Problems with the Electrical System

A modern electrical system requires a lot of care. It needs to have the right configuration to run all of the features that matter the most.

One NHTSA complaint shows major problems with this system. “According to the dealership where I bought this car, the ignition coil failed. This has happened two times so far, resulting in two separate trips to the dealership to diagnosis and repair the issue. They were able to reproduce and confirm the problem; however, what caused the coil to go out is unknown. The component has not been inspected by any other sources outside of the Hyundai certified mechanics at the dealership. No warning lights or messages appeared at time of occurrence; however the engine would rev up when switching between hybrid and gas modes causing the car to lunge forward. The car also would lose power and not accelerate placing me in extremely unsafe conditions as this has occurred on the highway both times. The car is currently at the dealership getting another ignition coil installed. The second time these symptoms appeared caused me to lose power while turning into a gas station from the highway almost resulting into a t-bone crash with a semi-truck. I purchased this car end of February 2021.”

Hyundai knows there are major electrical system issues with the Elantra. Service Bulletin #21-BE-002H discusses how the radio software needs to be updated because there is too much disconnection occurring. Basically, the Hyundai drivers are spending all of their time asking, “Can you hear me now?”

Problems with the Engine

Having a potent powertrain is just one part of the equation. If the motor isn’t reliable, the drive is anything but enjoyable.

One Edmunds customer states, “Purchased a 2021 Elantra from Hyundai and within 2 weeks, had problems with the car shaking and check engine light came on. Took it in and they said it was bad gas but never syphoned it and ended up having to bring it back two more times. Turns out there were several misfires and then they really did nothing when I brought it in the 3rd time and it sat there for a day and a half. I brought the car home since the dealership wasn’t working to help and they wouldn’t do a collateral swap and tonight, the engine started starting up on its own so we parked it far from the house with the hood popped open so it wouldn’t start up and if it did it wouldn’t catch the house on fire.”

Hyundai doesn’t walk around unaware of engine issues. Service Bulletin #21-01-048H discusses how there is a coolant leak in some vehicles. It is caused by machining burrs located at the mounting port of the cylinder head. With an overheating engine in play, the Elantra isn’t worth a dime. Instead, it should be sitting in the nearest junkyard, where it should be awaiting a wrecker.

Problems with the Steering

Keeping the Elantra under control seems to be a problem in its own. Customers continue to talk about losing control of this popular model.

Another NHTSA complaint says, “The contact rented a 2021 Hyundai Elantra. The contact stated while driving at various speeds, the vehicle drifted to the left and to the right. The contact stated that an unknown warning light was illuminated.”

When the steering gives out, it would be imperative to have a well-running braking system, but this is just as defective. Service Bulletin #20-BR-002H talks about brake fluid leaking from the caliper area, leaving drivers at risk when the system is needed the most. Maybe this is the “edge” that Hyundai brags about – causing everyone to put their life on the line.

Problems with Vehicle Structure

While the Elantra isn’t considered a high-end car, it should still be constructed with superior materials and manufacturing practices. However, that doesn’t seem to be the case.

A final Edmunds review reads “I bought the highest trim. 1- The trunk wasn’t closing properly. 2- The door panels squeaks and makes sounds at the slightest vibration. Badly assembled.”

There’s a recall that illustrates the lack of care in constructing this vehicle. NHTSA Campaign Number 21V30200 states that affected vehicles have front seat back recliners that weren’t welded correctly. This defect can cause the seat back to separate from the frame if a crash occurs. Truly, this car is forcing people to live on the “edge” even though they just want a safe ride.

Sometimes upon depressing the accelerator the engine does not respond. The car does not move in a traffic situation. Putting the car in park, shutting it down and restarting makes it go away for a while. Getting on and off the highway is especially dangerous. This has happened intermittently for the past 1-1/2 years. The dealer says that they cannot reproduce the problem. So, they cannot repair it.

The forward collision warning stopped working several months ago. We gave the (leased) car to the dealer for repairs after 4 weeks of waiting (parts, etc.) we were told the car was fixed and ready for pick-up. I drove it from baltimore to dc for a meeting and on several occassions when car stopped abruptly in front of me on the highway it did not give a warning, when I tried using cruise control, it would not engage because the conditions for doing so had not been met - same message I had when foward collision was not working. It's pretty clear that this was not fixed and instead they must have changed the messaging so that it does not appear as a warning when you start the car. The feature is really important to us because it has prevented a potentially fatal accident on a winding road in ny state where we found a truck on our lane due to a downed tree on the other lane - the car braked well before I did- which is the point of these safety systems.

While driving in stop and go traffic this morning (02/06/2023), at approximately 8:45 am, my hyundai elantra began accelerating on it's own. I applied the brakes and the car behaved as though I slammed on the brakes. The acceleration and braking issues happened multiple times during this drive. After the first incident, I shifted the car into neutral, (when it happened subsequently) until it quit accelerating, which was a couple of seconds. I have scheduled service at the hyundai dealer for tomorrow morning (02/27/2023)

Description
Our problem started a few months ago. At first, we thought it was just a fluke, but this issue has happened too many times to be so. The issues are, the car does not accelerate when we depress the accelerator, we see the tachometer move, but the engine is not actually accelerating. Then at times it will accelerate on it's own, while sitting at a red light, the car tries to move forward despite having our foot on the brake, it acts like we are trying to push the accelerator and the brake at the same time. Even worse, while driving, the car will go into accident-avoidance mode, even though there is nothing in front of us. There are no errors or codes populating on the dash.

I had reported that the horn wouldn't work.. Especially in cold weather last winter. The horn would work by the time I arrived at dealer. Told nothing they could do as it was working. It has happened 3 times in the last 2 months, finally totally nonfunctional the past 3 days. I called, stopped at dealer to have it checked. The car was returned to me with service person telling me that the horns diaphragm is stuck. When asked if working , he said for "right now." he told me a new horn(s) were ordered. I asked him what he did: he replied, I hit the horn with a rubber hammer until it worked! Well, one mile or so down the road, it didn't work. I checked the internet and there are multiple instances listed of ongoing issues with the horns on hyundai vehicles. In the end, I am driving with some hesitance as the horn isn't working. This is not acceptable in a car 1. 5 years in my opinion. Again, after checking on the nhssa website, no recalls or mention of this safety issue! Please escalate this to top priority! If not, anyone's injury or death is worth the wait!

Nhtsa recall number 22v354000 has been active since may 18, 2022. The dealership says no dealers in the area have received the part to fix it. The recall itself carries serious safety concerns as the seatbelt will explode metal fragments in an accident. The dealer has also told me that 35 other people are waiting for the recall to be fixed as well. This is ridiculous, hyundai needs to get these parts to the dealers.

I picked up my hyundai elantra n-line today 12/1/22. My car was at the dealership for almost 3 weeks for transmission judder (shudder?) issues and they claim to have fixed the issue with a tsb (technical service bulletin) from hyundai with some snap and cable and additional work that was not disclosed. After picking it up and driving only 3 blocks my car went berserk where all dummy lights went on, the car's engine revved to redline, took off and suddenly the front wheels turned left (due to the avoidance features of the car perhaps) and I was able to pull the emergency break and stop the car. The car stopped luckily and if the e-brake did not work I would have ended up hitting the rear corner of a car and into a house. While the car was stopped, it was still on (unable to be turned off), all lights blinking including dummy lights and the car was showing still in drive mode even though the revving stopped and the car was dead stop. After 10 minutes I was able to turn the car off (push button). Dealership dispatched a tow truck and now my car is back at the dealership for investigation. Note: tsb is something that is a known issue from hyundai but not yet to the level of an official recall is what I was told by the dealership.

On february 23, 2022, I was involved in an accident with the hyundai elantra, vin# [xxx]. The vehicle's brakes failed, and I struck a blue ford escape from behind with a speed of approximately 37 mph. On january 13th, I made an appointment with the napleton valley dealership in aurora, il. Where the vehicle was purchased complaining about the brakes and drifting into an intersection on route 83 and sycamore rd. For 20 feet. The mechanic checked the brake pads, drove it for 3 miles and deemed that the vehicle's pads were adequate. It was determined that no problem was found, brakes checked good, all within specs. (12,818 miles). The vehicle was towed from hinsdale, il. To dekalb, il., approximately 85 miles to my residence at 612 magnolia st. Dekalb, il. 60115. It was then towed a distance 3. 2 mile to dekalb body and collision, 116 industrial dr., dekalb, il. 60115. Since then, it has been back in the dealership for issues related to the engine, taillight, and a series of additional inspections verifying that the codes were working. On march 8th when I visited the body shop & collision I was told to “hire an attorney”. The vehicle was defective and should have never been on the streets. Preliminary findings on vehicle were concerning as far as airbag sensor was impacted but no airbags deployed at the time of impact. Upon vehicle arriving at our repair facility, we conducted pre-repair scan vehicle codes read as followed (see picture). Impact sensor was highly damaged, expected to have had airbags deployed at the time vehicle was impacted. Vehicle received front-end damages which resulted in needing the following parts replaced, front bumper and grille. Crash impacted the front bumper reinforcement resulting in some hours needed on frame machine to align front-end. Engine cooling system was impacted resulting in the need to replace radiator assembly and a/c condenser assembly. Hood and both front lamps are needed to be replaced as well.

Hello everyone. I need help I have a 2021 hyundai elantra and I have had the same issue for over 10k+ miles and 6 months. My traction control light, (no matter what speed or acceleration/deceleration.) will flicker on and off, make a horrible noise almost as if the abs is applying but no abs light comes on, and the pedals will go stiff and the whole car jerks. My 2021 elantra has had a new transmission put into it and when that didn't fix the issue, the wheel speed sensor was replace… well if that had fixed the issue, I wouldn't be writing this post. After a new transmission, and wheel speed sensors, didn't fix the issue the dealership themselves advised me to look into the lemon law being they had no idea at this point what was going on with my car. I have attempted getting my car bought back under the lemon law (ohio) which my car meets the qualifications being that the issue was brought the the dealerships attention, before the 12 month or 18k (whichever came first) which in this case was taken to them before both. And that my car had been in the shop more then 30 days cumulative (it's been 41) and hyundai has denied my request for a buy back, and has told me I need to do more research or get an exterior 2nd opinion. (pretty much a lawyer). They've advised me to “just keep taking it to the shop and get it fixed”. The issue is, this does not occur all the time. It is completely random and will do it once in a week and then not again for another 3. But when this happens, it's scary. It's loud, the pedals go stiff and the whole car jerks. Accelerating or decelerating. The dealership will not replace something if they cannot duplicate the issue which is also a reason it's taken so long to get any sort of answers. I have multiple videos, the service manager, has rode in my car with me while this issue has occurred and stated himself my vehicle is unsafe, and I should not be driving it. I need help!

The car was brought back to the dealership after a few months after noticing that the steering wheel would shake and the car would jerk when brake was applied to slow down. In normal street driving as well as during highway driving. The dealership since it was under the warranty replaced the front rotors and the brake pads to solve the issue. Within the one year of purchase of the car, it was once again having the same issues of steering wheel shaking and the car jerking motion back and forth. When he car was brought back to the dealership they said that it was not under the warranty and that they would not address the issue and that if I wanted it to be fixed I would have to pay out of pocket I think that there is something wrong with either the rotors or the braking system that is casing this shaking and the car jerking when trying to slow down, and it should be addressed and investigated further.

At about 11 months old my car suddenly seized while attempting to enter the highway. This came with no type of warning from the vehicle until the car had stopped and then every light on the cluster came on. I was fortunate not to be rear ended. The car was towed and 2 days later the dealership called to tell me there were no errors and nothing was wrong with the car. I told them what had happened and they called later that day and I was informed that they needed to install and entire new engine assembly. The car only had 7000 miles on it and should not need a new engine. There is some major design flaw with this car which poses a safety issue. Additionally I looked at my service records for the car and it looks as if the dealership is trying to cover up the fact that a new engine was placed in the vehicle as it is listed as routine maintenance. Please look into this and contact me if needed

Sometimes, for no reason my car will not accelerate (no amount of pedal to the metal will help) and then when it does accelerate, it surges forward at random points and tries to overpower the brakes. This has happened multiple times and the dealer claims they have never heard of this happening. It could cause a serious accident when it happens.

A squirrel chewed my wiring into the temperature coolant sensor. I had to have two different rental cars for six weeks before I received my car back. Nothing happened to those vehicles during those six weeks. Within a week of having my car (2021 elantra) back, a squirrel chewed more wiring. My car is now needing another repair. This is a known issue with hyundai as well as other makers. I feel it's pretty compelling evidence that there is a problem as two vehicles were not bothered by squirrels for six weeks and then my car comes back and it gets chewed up again right away. All cars were parked on my driveway.

Two matters: 1) the recall notice "campaign 216" regarding my 2021 hyundai elantra has not yet been remedied nor has hyundai announce a timeline for a remedy. It is regarding the windshield. 2) secondly, my horn stopped working 100% and I took it to hyundai last week and they said a lot of 2021 elantra's were coming in with broken horns. They ordered me a brand new part that seems as though they redesigned the horn system. It will be replaced this week. I asked if I missed a recall and they said no, the horn problem has not yet required a recall but they seemed to suggest that the horn issue is a real matter effecting their elantra's. I would hate for other 2021 owners to suffer a horn failure when they actually need it in a real life safety situation. The horn just stopped working. The horn is a safety function and if that is broken what can one do in an urgent matter "yell", not likely. No warning ahead of time... Just one day it stopped working with no indicators.

On multiple drives the car has "lurched" or accelerated when foot was not on the accelerator pedal. These were minor issues, but unnerving when pulling up to park near a structure. Today 3-23-22 I was driving and after about 1 hour of normal operation the car began to accelerate while pressing the brake, and decelerate while pushing the gas. The engine was revving and then slowing down opposite of what would be expected. This is a hybrid vehicle - it felt as if the gas engine was supposed to be spooling up to charge the battery but instead was feeding power to the wheels. There was no engine light illumination from this. I restarted the car and it seemed ok. Honestly, this was scary - trying to move from one lane to the next to an exit to safely exit the morning rush hour freeway. I had to keep my foot heavy on the break to make it slow / stop. On two other previous drives the vehicle "lurched" / the car "bucked" once or twice and then the gas engine would not re-engage. The mil came on, and the car drove on battery power only. I drove off the road, restarted, and the vehicle worked fine. By the time I got the car to the dealer the mil had cleared and they were unable to pull any codes and deemed the car safe / found no issues.

Wireless apple carplay frequently disconnects at random during drives. I've got the latest iphone update, done every reset in the book, and spoke with my dealership and there is no solution. It is also impossible to use a wired carplay function despite a data-usb input. It is a totally unnecessary move to force users into using this failure of wireless technology. The screen will frequently black out for an extended period of time creating a challenge if you are following the navigation. Additionally, you must tap through 3 warning pages before being able to access the streamed maps or other content again. It is distracting, unpredictable, and continuously more frustrating as neither hyundai nor apple have provided a solution that works and instead resort to a “blame game” of each other. Furthermore, both companies act surprised when hearing about this issue, but a quick google search shows many users struggling with no solution in site! This started the week I bought my car (brand new) and has only gotten worse since.

In the middle of crossing the verrazzano narrows bridge in new york city, the forward collision warning came on and the braking system automatically engaged repeatedly. I was traveling about 30 mph and had about 4 car lengths between my car and the one in front. The system kept engaging no matter how much room I put between myself and the car in front of me, and as I was in the middle lane of a bridge in heavy traffic I could not pull over. I always keep a good distance in front when driving, but because of the system inappropriately engaging I almost got rear-ended about four times. I was terrified and this continued to happen until I got off the bridge. I use my car mainly on the weekend, and also travel this bridge almost every weekend and this was the first time this happened but it was terrifying and extremely dangerous!!!!

According to the dealership where I bought this car, the ignition coil failed. This has happened two times so far, resulting in two separate trips to the dealership to diagnosis and repair the issue. They were able to reproduce and confirm the problem; however, what caused the coil to go out is unknown. The component has not been inspected by any other sources outside of the hyundai certified mechanics at the dealership. No warning lights or messages appeared at time of occurrence; however the engine would rev up when switching between hybrid and gas modes causing the car to lunge forward. The car also would lose power and not accelerate placing me in extremely unsafe conditions as this has occurred on the highway both times. The car is currently at the dealership getting another ignition coil installed. The second time these symptoms appeared caused me to lose power while turning into a gas station from the highway almost resulting into a t-bone crash with a semi-truck. I purchased this car end of february 2021.

After the dealer told me they could do nothing, I opened a case with hyundai motor. Hyundai motor has failed to reply or report back on a resolution. Initial report was made on 5/13/21 and a case # was assigned (case manager assigned on 6/5). As of today, 6/9/21, hyundai motor has not yet contacted me for a resolution.

    Great article. Really helpful to see that it’s not just me. I have a 2021 Hyundai Elantra Hybrid Blue. Started having issues with the forward collision sensors mid road trip. No bumps, no nothing crazy, just driving on the open road and then the. cruise control kicked off and the sensor warnings came on. Brought it in, the dealership had it for an entire week. They recalibrated and it worked for about a week and then failed again, and it was back in the shop again several weeks later. They ordered a new part and when it finally came in, it wouldn’t calibrate because “the signals from the sensor were being sent to the wrong places on the control board”. While there, they performed a software update. Now the car lunges suddenly when slowing down or stopped. I have to drive it with my foot over the brake to keep it from trying to get me to participate in an unintentional street race or rear end collision. I will be bringing it back to the dealership for a 4th visit to troubleshoot the sensor when the next one comes in. Also, to troubleshoot the lunging acceleration/deceleration/jerking issue, and to troubleshoot a whirring sound that the steering wheel just started making. This car gets me to work, but I’m starting to worry for my life and those of the other hundreds of thousands of drivers I pass by every day. Not sure what more I can do here.

    My Elantra hybrid Reeves up, lunges forward, or stalls leaving you a sitting duck while pulling onto the road. When it lunges forward it is hard to stop the car which is a serious safety issue for rear end collisions etc. No service light has come on and their crappy software diagnostics shows the car has no issues. After being towed to a second dealership the tech experienced the lunging etc while on a test drive. For the 4th time their computer diagnostics failed to detect any issue. With a big to-do Hyundai USA advised the dealer to replace the transmission and after 2000 new miles the same lunging and reeving and stalling happened again. So Hyundai failed to fix the issue with my car for the 4th time. The car is back in the shop and a rental was never offered from this terrible company. Stay away from these cars they are not worth the headache. They need investigated for their fraudulent diagnostic software that is keeping these cars on the road and preventing people from lemon law proceedings, fraud is fraud. In fact if you are involved with a person driving a Hyundai consider suing Hyundai USA. They know all about these issues and don’t care to address them until someone is killed. At this point I would call it manslaughter.
