Three-row SUVs are the latest rage for family travel, and the 2018 Mazda CX-9 is one of the top choices. The newest lineup claims that it’s “never ordinary,” and owners couldn’t agree more, especially since the majority of vehicles aren’t dealing with a faulty electrical system, defective fuel system, a malfunctioning steering system or shoddy structure, as this one is.

Problems with the Electrical System
Electrical system issues can range from annoying to dangerous. No matter what level of problem is faced, it can be exhausting trying to figure out what’s wrong.
One such electrical system complaint comes from a customer left on the NHTSA website. “Driving the vehicle to an abrupt stop and I had no control. The dashboard lit up with all types of warnings and heat was coming from the front of the car.”
What’s worse than this is a Mazda recall that also affects customers. NHTSA Campaign Number 19V403000 states that the wiring harness connectors provide weak retention force, causing the passenger frontal air bag to not deploy during an accident. This issue can also cause inoperable turn signals, making it impossible for other drivers to know what’s going on, which only further leads to a higher instance of a crash that requires the air bags to work. It seems the automaker is hitting owners from every end with this malfunction. It’s just one way that Mazda wants to live up to its “never ordinary” reputation. Where most companies deal with a recall causing one problem, this defect causes countless problems.
Problems with the Fuel System
The fuel system ensures the engine has what it needs to move properly, but what happens when it becomes defective? Numerous problems can exist, from the inability to move at all, to complete lack of control over the engine power.
Here’s what one complaint left with the NHTSA had to say. “I was waiting in a stationary position, at a red light, behind some other vehicles, with my foot on the brake pedal. All of a sudden the vehicle started to lurch forward as if someone had stepped hard on the gas pedal! I was struggling to keep the car still by depressing the brake pedal harder, but it wouldn’t stop the car. I had to put it in Park and turn off the engine to stop the forward thrust of the vehicle.”
There’s another fuel system-related instance that the automaker owns up to. Service Bulletin #01-003-18-3421 states that some owners have trouble getting power out of the engine, but there aren’t any warning lights or DTCs. The cause is listed as a high fuel temperature, forcing the learned pressure to exceed a level that the PCM limits engine power to avoid fuel injection lack. To counteract this, technicians must upgrade the PCM control logic to allow for more power. Why the CX-9 wasn’t allowed to have access to this power from the get-go is anyone’s guess? That might have been too ordinary.
Problems with the Steering
When traveling with seven people, owners want complete control over the steering, but this is a major concern with the CX-9 models.
One Edmunds review says, “Above 65mph it has a vibration. I went back and drove a GT and T model to see if it was a difference in tire size, but that wasn’t the case. All three cars had the same thing to some degree.”
Other steering problems have also come to light. Service Bulletin #02-004-19-3574 states that customers are complaining about the steering wheel being more than three degrees off-center, even while driving on a flat, straight road. Technicians are told that up to three degrees is considered normal and should be left alone, while anything more than that can be repaired. Why did the steering wheels get put on off-center? Maybe to make the vehicle even more extraordinary in the eyes of the automaker.
Problems with the Vehicle Structure
One more aspect that helps to set it apart is the structure. It wasn’t built the way it should have been. It doesn’t take long to find countless complaints about the integrity of the vehicle.
Here is one Edmunds review that discusses the concerns. “Within four months there were numerous chips along the front of the vehicle. I have never had a vehicle chip s profusely in such a short period of time. Also do not have this chipping on our 2017 Mazda 6 which has standard paint. The paint just does not seem durable. When I took the vehicle in a six months for a service I pointed out the chips to the dealership service advisers. One service adviser even pointed out what he thought were a couple of paint imperfections. But Mazda representatives said this was normal wear and tear and would do nothing to repair. If this is normal wear and tear on a vehicle that is not even a year old, then the upgraded paint is not worth the cost.”
There’s never a normal reason for a car’s paint to chip in less than a year. Any dealer that tries to state that is truth is simply covering its own butt. But, it turns out; the paint isn’t the only part that wasn’t manufactured correctly. Service Bulletin #09-018-19-3584 states that the door weatherstrip also comes off at the lower, front part of the rear doors. The automaker claims that it was caused by an insufficient gripping force applied by the factory. To correct this, the dealers have a newly shaped weatherstrip that should adhere better. Of course, Mazda will replace this weatherstrip, which only costs peanuts compared to a new paint job. When it comes to the more important and extravagant structure-related repairs that need to be made, it’s impossible to find the company stepping up to the plate. Once again, this only proves that the company is anything but ordinary, but it’s also likely that Mazda is losing valuable customers in the process.

| Description | Coolant leak into cylinder head, resulting in overheating and blown head gasket. Repair cost was k to resurface cylinder head and replace gasket. Repair did not fix issue, likely due to unseen cracks or warping to cylinder head. Will require rework, likely entire engine replacement, as the defect cannot be corrected. |

| Description | The infotainment system screen has developed several cracks in the upper left-hand corner of the screen. Often time these cracks look like spiderwebs or frost --it's commonly referred to as "spider cracking." this is the second time my vehicle has had this issue. At the present time, the cracks are contained to the upper left-hand corner of the screen, but they are getting larger. The vehicle has been inspected by my local mazda dealership and I'm awaiting a resolution. As I understand, this is a known issue with 2016-2017 model years and a tsb has been issued for these years. Mazda should extend the tsb to 2018 and beyond. |

| Description | The main infotainment display randomly exhibited "spider cracking" which obstructs the view of the material being displayed within the screen. It is unsafe because the operator is unable to see maps, time, locations, controls, reverse cameras, etc. All of these are displayed in the screen and, due to the manufacturing defect, the operator is distracted by straining to see what is displayed behind the cracking. This is a well documented issue plaguing mazda vehicles. Mazda has admitted it as defective, and are fixing the problem in the 2016-17 models. However, the 2018 model (which has the same screen as the 2016-17) is being refused. The fix needs to be extended to the 2018 model and beyond since it iw clear this it is still a widespread issue. It is well documented that once the cracking starts, it quickly spreads to the entire screen if not repaired, causing even more danger to the operator who will be distracted while attempting to see the display behind the screen. |

| Description | 2018 cx-9 gt that has experienced spider cracking in the upper right corner of the infotainment screen (the cracks are inside the screen). This started after the car sat at the dealers lot in cold temps while waiting for repairs to the engine feb 2022 (mileage on car at that time as about 36k). Mazda had issues a service alert on 2/20/18 in regards to this issue for 2016 - 2018 cx-9's (along with other model of similar years). No mention to me by dealer (who I have taken car to for all service matters from 1st day of purchase). Mazda then issued a warranty extension program letter dated 5/06/20 to dealers, service & parts manager that they would extend warranty coverage to fix this issue, but only for 2016 & 2017 cx-9 vehicles. Over time the cracking has gotten worse & is slowly growing in size. (some other owners have it cracking in different parts of screen, which renders the touch screen useless). Mazda should include 2018 in the warranty extension program, so this issue can be resolved for all years affected. |

| Description | Driving the car home from work, the engine temperature gauge started to go up high. I added coolant that same night. Went to the dealership for a check up. I was told the coolant was coming out from the back of the engine and will need to partial repair the engine. Only 75k miles in the engine and that was an estimate cause I could need a brand new engine. Now I'm stranded with out a car waiting for a response. Mazda should do a recall regarding that issue cause I've seen a lot of cx9s have the same issue. Thats not good for reliability. |

| Description | After owning this used vehicle for about 11 months, the engine temperature gauge indicated the car was running hot - about 240 degrees. After inspecting the vehicle at home, we added coolant to the system. This helped maintain engine temperature temporarily, but we noted over the next several weeks that the coolant was dropping rapidly. After inspection by a mazda dealer, it was concluded that the cylinder head needed replacing. |

| Description | > I have a 2018 mazda cx-9 with about 70,000 miles on it. Since 2020 this vehicle started developing cracks in the infotainment center screen. I only had about 23,000 miles on it at that time. The cracks are now starting to obscure my back up camera, communication system and nav system displays causing a safety issue. It is distracting to not be able to see clearly on this screen and I am afraid something will happen to me or my kids. About a year ago I did take this car to the local mazda dealer, for the longest time I thought I did something to it, but I did not. They called mazda customer service and no good will was offered. There is a technical service bulletin out but not a recall. There are several models older than my vehicle that have had this screen repaired free of charge by mazda. Same issue - nothing different then what is going on with my car. There are many many of the very same complaints online. Can some please investigate this issue. It is ridiculous. |

| Description | I purchased my 2018 mazda cx-9 grand touring cpo with 39k miles and was sold the life time extended powertrain warranty through the dealership. The car now has 74k miles. While sitting idle at the school bus stop in my neighborhood waiting for my daughter the temperature gauge light comes on. I immediately drive home (exactly 0. 3 miles) not going over 10mph back home, park call a tow truck company to tow it to the priority mazda dealership in tysons corner, va from which I bought it. After a few days the mechanic calls and tells me there is a coolant leak and the repairs for the cylinder head should be covered under my lifetime extended warranty. A few days later I get a text message from the service rep that states. "unfortunately, the extended warranty has denied coverage of the cylinder head, stating it to not be an internally lubricated issue.... We need to fully inspect to determine what is needed (cylinder head or full engine due to overheating) cost of teardown |

| Description | Mazda has refused to admit and repair a clearly defective screen, affecting visibility of the camera system, navigation, climate controls and infotainment. Pictures attached are several months old and the issue continues to get worse. The dealer says "corporate won't cover it", corporate customer service will not respond to repeated attempts at contact other than a generic "your vin is not covered". Service alert direct from mazda and pictures of my screen showing the exact issue are attached. For a k+ vehicle with less than 30k miles on it (less than 20k when the issue started), this is unacceptable. Please hold mazda accountable. |

| Description | While commuting home on 8/19/22 my cx-9 began overheating and coolant temp. Warning light illuminated on dash. This was a dangerous situation as I had to stop in the middle of traffic for fear of ruining my car and risk getting rear-ended and also navigate to the shoulder of the road. Took the car to the dealership where they confirmed p111a engine overheated dtc and coolant leak. Cx-9 has a cracked cylinder head, the exact problem outlined in mazda tsb 01-013/21. This happened at 61,xxx miles... Roughly 1,000 miles outside the powertrain warranty however it's highly likely this crack and leak developed well before the end of the powertrain warranty period. |

| Description | Spider cracks in both the left and right top corners that continue to spread, creating larger blind spots while in reverse. This is an issue that mazda is aware of and impacts many models from 2014 until 2019. Even though this may not be considered a "safety feature" in it's traditional form, it has become common practice to rely on this feature while reversing the vehicle. Much like additional airbags may not be required, if they are, they should be fixed when they are proven to be faulty. Both the local dealer(roger beasley austin north) and mazdausa refused to cover the cost of fixing the issue even though they are aware it is faulty. There is even a service notice that was put out by nhtsa that discusses this issue and my model is included, however I have been repeatedly told my vin # does not qualify. |

| Description | Within 6-8 months of purchasing the car we noticed the brakes squeaking and vibrating. At that time the car was under 25,000 miles. At our maintenance check it was advised that we have the brakes resurfaced at the next appt. Back brakes were done in 3/2019 and the front were done in 6/2019. We noticed the squealing and vibration returned again. At our recent maintenance check, we asked to have the brakes and rotors inspected. We were told everything looked fine and nothing needed to be done, however we are still experiencing the vibration which is very troubling. We called another place explaining the issue and they said that it sounds like we need new rotors. Our car has mostly been sitting over the last year and a half with very few added miles. We're curious to know why a car with less than 25,000 miles on it needed the rotors resurfaced and why with less than 60,000 miles it needs new rotors. The brakes on the mazda suv's seem to wear rather quickly or perhaps the incorrect brakes are put on for this size of vehicle. The increased vibration seems like a safety hazard |

| Description | Happened to me two times in past three weeks, where I am coming to a stop, or hardly moving, and car suddenly accelerates. Had my foot on the brake and the car was still trying to accelerate. Yesterday, 4/24/21 it took all my strength on the brake to keep the car from pulling into oncoming traffic. I have been driving for 39 years and have owned many cars, and something like this never happened to me. I will be bring the car dealership tomorrow, the car has only 10k miles on it as we don't do a lot of driving with it as we owe two cars. I did not have my foot on the wrong pedal, this is very dangerous and if the dealer does not find anything with the car, I intend to sell it, as this is probably one of the scariest experience I had with a car. It is intermittent, so I am not sure when its going to occur, but twice in the last few weeks is not coincidence ( it also happened to my wife a few months ago, but we thought it could have been due to snowy road conditions). In one case I was coming up to a stop sign, and was braking and car was accelerating as I tried to break. I had to put car in neutral and the shut off car to get to stop. Yesterday, I was pulling out of a parking lot, and was waiting for an on coming car to pass me before I could turn onto road, when car was trying to accelerate, when I had my foot on brake, and took everything to keep the car from accelerating forward into on coming car. Once car passed, I made turn onto road, and issue did not repeat on the remaining mile to my house. I went onto a mazda forum and I saw a few others who raised the same concern/issue. |

| Description | Emergency parking brake ('epb') began to malfunction following recall to fix electrical components on mazda cx-9, 2018. Epb will not release, or will unexpectedly and suddenly release with car accelerating in gear ('drive' or 'reverse'). Most recently when activating the emergency parking brake ((car was on a a roadway incline) the brake would not release, after 2 hours of being stranded and of attempting to get the brake to release, ( including rocking/shifting/alternating gears/braking/seat belt on/seat belt off/ manual brake on/off and following all manual procedures repetitively) a cell phone call to the mazda service manager who suggested rocking the car back and forth between gears ) the emergency parking brake suddenly and unexpectedly 'released', sending the car lurching forward and requiring driver to slam on brakes to avoid driving over a cliff). Vehicle epb inspection requested, mazda service manager stated the epb is, 'no longer necessary for vehicle safety', blamed the malfunction on 'bread crumbs' , offered to replace a defective console switch (presumably with another new, but also defective, switch) but refused to inspect the mechanical/operational aspects of the automatic emergency parking brake system (for abnormal rust, water leaks, defective cables, defective electrical wiring, etc.). Mazda uses the same manufacturer of epb for all mazda cx series vehicles. Federal nhsa recalls for epb malfunctions were mandated for all mazda cx series vehicles - except the mazda cx 9. The cx 9 uses the same epb system as do the other mazda cx series models. It stands to reason that the braking issues for other mazda recalls is the same reason why the cx 9 should have recalls to fix the automatic emergency parking brake system. Please issue a recall for mazda cx 9 vehicles to fix the automatic emergency parking brake defect(s). Thank you. |

| Description | I wanted to say it happened to us while we were driving back from a daytrip on saturday. We had our kids in the car and my husband was driving. All of a sudden the scbs light came on and the car just stopped giving gas. The car behind us couldn't tell we were slowing down because there was no brake light. We were almost rear ended. The car behind us couldn't stop in enough time so they just swerved onto the other side of us. We had to pull the car over and it was almost nighttime. My husband ended up pushing the car to get it off the road and to a safe place. It would only go 2 miles per hour. I had my car towed to the dealership, I have not heard anything from them except they are continuing to look into it. It's a 2018 mazda cx9 with only 26000 miles. It's never been in an accident. I'm hoping that whatever the fix is, it's covered under warranty. If it was a truck or bus behind us, they would not have been able to stop either. If we were on a highway and this happened, there is no doubt it would have caused an accident. |

| Description | This vehicle is has been on lease for 1 year and has less than 4000 miles on it. Initially while attempting to start the vehicle that had been parked overnight it gave the following warnings: - keyless entry malfunction - charging system malfunction - vehicle overheating - battery malfunction the car would not shut off until I held the start/stop button in for roughly 20secs. The dealer service center took the car and told us the battery had a low charge, charged it and returned it. Several weeks later while the vehicle was in motion with 2 adults and 2 children on a city street traveling at about 20mph it gave the following warnings: - keyless entry malfuction - charging system malfuction - vehicle overheating - battery malfunction - pull over to safety at this point the vehicle was still in motion and the stereo, hvac, and power steering cut out. I was able to pull the vehicle over but again had trouble shutting it off. I had to hold the start/stop button for 20-40secs. The car was towed to the dealer service center. We were told by the service center that a lot of 500 vehicles of this year and model had an engine harness defect that no recall had been issued for but they were aware of defect and had a fix for it. I feel I was lucky that I was only traveling 20mph when the power steering cut out. If I had been traveling highway speeds on a bend the situation could have been tragic and I had my children in the car. Currently, based on what I've been told by the dealer service and sales managers there are potentially hundreds of other 2018 cx-9s which could experience this same malfunction while in motion. |

| Description | On friday (june 29th, 2018) around 9:29 pm, my car broke down while my family and I were traveling from rochester ny to boston massachusetts. I was driving down the massachusetts turnpike when all of a sudden my check engine light turned on and my car just started to slow down in the middle of the highway. I was able to pull over in time and called mazda roadside assistance because after the car stopped, it wouldn't turn back on. Since we were on a restricted highway, my car had to be towed and we were taken to a safer location. When the car was put down, it turned on and the check engine light was still on and the fuel gauge said that the car still had 40 miles left. The guy that towed our car said that it might have been a fuel issue, so we went to get gas. Once we filled up our tank the check engine light was still on but we were able to reach our destination. The next morning, I took the car to the nearest mazda dealership and they restarted the car and according to their report nothing was wrong with the car. They said that it was safe to drive but they had no clear reason as to why the fuel gauge wasn't stating the correct information. After the trip I, reported this issue to mazda and they didn't answer me until two weeks later. Their response was that there was probably nothing wrong with the vehicle and that this was a one time issue. I did research on my own and discoveries that someone from saudi arabia had a similar issue. Since mazda hasn't been willing to help resolve the situation I am filing this complaint because I am not willing to put my families life in the same risk again. |

| Description | I purchased a new mazda cx-9 in sept 2017 because it had the highly touted smart city braking system for which I paid thousands extra. I had had a previous rear end collision and wanted to be sure this system would at least warn me. I set up some cardboard boxes wrapped in aluminum foil. I slowly (10 mph) drove the car into them without touching the brake or accelerator. The car did not slow down or warn me.(I tried sending a video to you from my iphone which may not go through) I made an appoint to repair this obvious factory defect and significant safety issue. The service manager at olympia lincoln /mazda(and puyallup milam mazda) refused to repair it they stated and showed me a print out from mazda factory that forbids real time testing and stated that if the trouble light is not on they aren't allowed to repair or real time test it. I think that the factory is afraid of dealing with a massive safety recall. To compound things the active live traffic display doesn't work either which makes matters worse since I can't see where an accident has occurs in real time. I understand its defective in most mazdas with navigation in 2016 and beyond. The is a class action law suit starting to be filed about this. *bf consumer stated regarding defective automatic braking system on 2018 mazda cx-9. I have not heard back after filing this complaint 2 months ago. Updated 8/24/18*jb |
