2019 INFINITI Q50 Owner Complaints

Early turbo failure should be extended to newer vehicles not only up to 2018. I am experiencing turbo failure and there is no extended warranty for this repair.

Air bags failed. Auto has 28,000 miles and has no accidents. Warning light showed that airbags were not working June 2026. Auto brought to dealer, and it is a very costly job to fix. Auto just out of warranty in years not miles. Infiniti in previous years has had a recall on their cars, but not my VIN number for failing airbags. This is a manufacturing defect, and it should not have to cost me. Infiniti has offered a partial discount.

own a 2019 Infiniti Q50 3.0t Sport with approximately 80,000 miles. The vehicle began experiencing engine knocking/ticking noises, rough idle, hesitation under acceleration, shaking, and intermittent misfire symptoms. The issue continued even after replacing spark plugs and ignition components. The dealership/mechanic reported possible internal engine damage and metal shavings in the oil, indicating potential failure of internal engine components. The vehicle has been regularly maintained with oil changes completed on schedule. This appears to be a widespread issue affecting many Infiniti and Nissan vehicles equipped with the VR30 3.0 twin-turbo engine. Numerous owners online report similar symptoms including engine knocking, turbo failure, metal contamination, loss of power, and premature engine failure at relatively low mileage. The issue creates a serious safety concern because the vehicle can lose power, hesitate during acceleration, or potentially fail while driving in traffic or on highways. I am requesting that NHTSA investigate repeated engine failures involving the VR30 engine platform used in Infiniti Q50/Q60 and related vehicles.”

While operating the vehicle under normal driving conditions, the engine experienced a significant loss of power and reduced acceleration. The issue is believed to be related to turbocharger failure within the engine system. The loss of power created a safety concern, particularly when attempting to merge into traffic and maintain highway speeds. The vehicle did not respond as expected when acceleration was needed, which could increase the risk of an accident in certain driving situations. The problem has been confirmed by a dealership service department, and the vehicle is currently available for inspection. The diagnosis indicates that the turbochargers require replacement. Prior to the failure, there were limited warning signs. Any warning indicators were either minimal or appeared shortly before the issue became noticeable. The failure occurred at approximately 107,000 miles. Based on publicly available information, similar failures have been reported on this vehicle model, suggesting a possible pattern related to the turbocharger system.

The twin turbo failure is a known issue with Infiniti. I took my vehicle to the dealership and it was diagnosed with having a passenger side turbo failure. I have 145K miles on my vehicle. It is outside of the warranty period and very expensive to repair. Infiniti knows there is a problem regarding turbo failure in the Infiniti Q50 and the consumer is forced to deal with expensive repairs $7K for one turbo per the dealership. Had I been made aware of there being a problem, I would not have purchased an Infiniti.

Shortly after purchasing the vehicle, I began experiencing serious performance issues. While driving, the vehicle suddenly lost power, would not accelerate properly, and warning lights appeared on the dashboard. The vehicle eventually shut off while in operation. The vehicle was inspected by a dealership, which initially stated there were no issues. However, the problem continued and worsened. The vehicle was then inspected by an authorized Infiniti dealership, where technicians identified a consistent knocking noise coming from the engine. The dealership indicated that the noise is consistent with internal engine damage and recommended further inspection and likely engine replacement. The issue developed very shortly after purchase, and there were no prior indications that the vehicle had been damaged or misused. The sudden loss of power and engine failure created a potential safety hazard, especially while driving in traffic, as the vehicle was unable to accelerate and could have led to a dangerous situation. The vehicle is currently available for inspection, and the issue has been confirmed by a certified dealership. The cause of the failure is currently under further evaluation.

While driving, my vehicle suddenly shut off without warning. After restarting, the vehicle would not accelerate over 40 miles per hour. I had the vehicle inspected by the dealership, and they informed me that the engine oil filter contained metal debris. The dealership explained that the presence of metallic particles in the filter could indicate internal engine wear or damage, and they recommended a full engine replacement at a cost of approximately $20,000. At this time, I have not been shown the filter or the debris, but I was advised that this condition may require further diagnosis and possible engine repair or replacement.

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.

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.

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.

While vehicle is in “D” drive move the car would jerk likes its trying to shift/switch gears and jerk hard. It sounds like the issue would involve the transmission. Another occasion happened when I came to a complete stop, & then pressed on the gas, and the car jerks again then started to accelerate.

The car sometimes turning - changing lanes - just various times the rear end will slide around - or skid. Just does it various times - does not matter if the road is wet or not. Infiniti Service did not find an issue - but there is definitely an issue. No certain time so hard to pinpoint what is causing it.
