Problems with the Electrical System
It isn’t just luxury cars that integrate sophisticated electrical systems these days. However, the luxury car owners expect more when compared to a budget model. Yet, they aren’t getting it with this Infiniti.
Here’s one NHTSA review to consider. “Driving on interstate at 70 mph with active cruise engaged. The instrumentation all went black, cruise control released but engine continued running and I used manual acceleration in order to maintain speed in the flow of traffic. After approximately 30 seconds, the system re-booted. Instrumentation came back on and I reset active cruise control and all appeared ok. After a few days, we were returning home and as described earlier, the same event occurred on the interstate. I took the car to the dealer, described the incident, they reported they had seen that before, checked the computer and saw no codes and said it must have been a system reboot.”
While that must have been a scary situation, there are even more serious concerns. NHTSA Campaign Number 19V654000 states that over a million vehicles can suffer from a back-up camera image that doesn’t display correctly. Whether the car is cruising on the interstate or attempting to back out of the driveway, it’s clear that the computer glitches put people’s lives in jeopardy. Talk about thrilling!
Problems with the Steering
Thankfully, the above complaint didn’t involve trouble steering as well or that could have been a disaster. Still, steering issues are being reported.
Just look at this Edmunds review. “I took my car in the first month because of it drifting to the right constantly and was told its roadcrown but nothing ever inspected. Roadcrown is in the right lanes not every lane. The 4th month the run flat on front right blew out on the sidewall but was no potholes around and roadside assistance never came to tow my car. I had to buy 4 new tires. The 14th month new tire on front right has sidewall damage again with a crack on the inner lip of the rim. Rim was replaced but nothing else inspected. Potholes will throw a car way out of alignment. I went to pay for alignment and only spec out was the left front toe. Now in spec car drifts to the right even more. So if you want a self driving car lol that will go from the left lane to the far right lane in 2 to 3 seconds all by its self I guess its for you. If you want a car that will be a constant money pit, unsafe and warranty not covering this car is for you.”
Aside from the steering concerns, Infiniti has also addressed trouble with the tires and wheels. Service Bulletin #ITB20-003 states that the TPMS sensor could be leaking air in some vehicles. In the affected vehicles, it could be occurring continuously, causing a loss of air pressure that becomes dangerous. To repair the problem, technicians must replace both the valve stem washer and valve nut. So far, it’s clear that the advanced systems meant to keep everyone safe are simply just backfiring and causing more trouble after all.
Problems with the Transmission
From the mechanical standpoint, the powertrain and transmission must be working correctly to provide a smooth ride. Yet, this is another source of complaint from owners.
One Edmunds review states, “Infiniti reprogrammed the transmission to shift into higher gears at slower speeds. The results are being in 5th gear at 30 MPH. I am sure this was in an attempt to maximize fuel economy but the result is lugging this great power plant to a pedestrian level. Tranny is also harsh on downshifts from 5th to 4th and 4th to 3rd.”
It turns out that Infiniti had so many problems with the transmission that a stop sale was issued on some vehicles. For that to occur, the automaker had to be concerned about something major related to the transmission torque converter, further proving how much of a disappointment this luxury car actually was. At this point, customers looking for a thrill might do better off sky-diving or bungee jumping instead.

| Description | This car has been drifting to the right since bought causing premature tire wear which has now been 5 sets of tires in 36k miles. The front right tire always seems to blow out. Alignment has always been knocked out in within weeks. Several independent shops point to defective bushings while infiniti doesn't see the issue. This same issue was recalled for the 2016 models. I've replaced the knuckle and lower control arm and now stays aligned but seems to causing premature tire wear and blowing the right front tire. I cant get more than 10k miles out of a set of tires and constant fighting with the car drifting to the right. I have several more documents. The consumer stated the reason for the drifting, the tire tears, and alignment knocking was due to a defective rack and pinion. The consumer stated that the dealerships are refusing to replace the defective part on the vehicle under the warranty that is now expired. Paying for alignments and tire replacements is a waste of money considering the root of the issue has not been fixed yet. The consumer stated that due to the multiple issues, they will not be able to do a private sell of the vehicle. The only option would be to sell it to the dealer. |

| Description | Passenger front seat shakes/vibrates even at lower speeds and it makes lots of noise. Tires were checked and has nothing to do with tires. I actually googled issue on my model and there are tons of posts with this exact issue. I have an appointment for dealership to look at issue in the next couple of weeks. My concern is that other consumers who have had issue that I've read about online had not had the problem rendered. It was not considered part of warranty. I'm my opinion, it should because it's an obvious defect. I should not have to pay out of pocket to have this corrected if it's defective. |

| Description | I have 3 issues with the car. The braking issue presented itself last in time but is most important relative to safety. Around mid january 2022, my car, while I was driving, and without any notice, began to decelerate/brake for no reason. My car is equipped with front driver assist but there were no cars, hazards, in front of me. It was a clear, dry day and the car was warm. It was momentary and fortunately no one was behind me. The car beeped, but there was no other warning. The second time this same event happened, however, the accelerator pushed back against my foot. Again, no one was in front of me and it was a clear, dry day. The third time this happened, the car beeped and what I know now is the cruise control indicator, appeared on the display. I did not touch the cruise control to activate. The other two issues were that both display screens were blacking out and rebooting while driving, for no apparent reason. The other issue is with the sirius xm satellite, which is not functioning properly. I have informed sirius xm of this issue as well. Given all of these issues, possibly all electrical, I contacted my local infiniti dealer to assess, with special concern for the random braking issue. The car was assessed and they could not duplicate any problems. They mentioned that perhaps if they had more time they may be able to duplicate the problems. The following monday, I took the car to the dealership and left it overnight for assessment. I was called the next day and advised that they could not duplicate the issues. The dealership returned the car without making any repairs, diagnoses, or being to able to duplicate problems. Since the car has been returned to me, it has continued to have problems. The braking issue has happened twice since, with one time involving the accelerator pushing back. The screen has blacked out and gone into parking mode, while I was driving. I have contacted infiniti corporate to advise of problems. |

| Description | I originally owned this q50 2018 vin [xxx] and infiniti replaced it with the one I had listed. The fact is I own neither of them any longer but feeli should report it because it is a safety issue which infiniti refused to deal with. The blind spot light did not work on either car . Between 10 am and 8 pm you could not see the light and audible signal you could barely hear. I am reporting this problem in the hopes of saving lives. It was a safety issue it cost me $$ the second replacement but never felt comfortable in the car . Yet infiniti could care less though the dealer was very helpful information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6). *tt *tr |
