Catastrophic engine failure. Metal debris in the oil. Manufacturer defect.

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.

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.

While driving vehicle if you suddenly stop vehicle would stop, however when applying pressure to gas pedal vehicle would not move, if foot is left on pedal car would jerk and then proceed forward. Unlike other vehicle after breaking hard vehicle would move without hesitation.

Unintended acceleration. Pulling into a parking space in a shopping center parking lot, after going over a speed bump and making a left hand turn into the spot the car accelerated and would not stop. Pushing on the brakes did not work. Car has a system to prevent crashing in to an object in front of the car but that did not work. The car struck a pole in the parking lot doing significant damage to the right front of the car.

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 sh

Rm collision forged my signature to cash out 20'000$ and did not fix my car. My car was stolen june 15, 2019

Vehicle was purchased December 2021 upon purchasing the vehicle I noticed the horn was not functioning, vehicle was taken back to dealership, they corrected the issue, then months later horn isn't functioning at all. Nor is Lane Departure Warning, Lane Keeping Assistance, Parking Collision Warning, Rear Cross Traffic Warning functioning on car. The automatic rain sensor isn't working at all.

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, thy reported they had seen that before, checked the computer and saw no codes and said it must have been a system reboot.

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

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.

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 consu

This car has always drifted to the right. Now it is drifting to the right and left. Constantly having to correct steering to keep straight. Car pulls hard to the left when braking. Going over bumps or at high speeds the car feels very loose and getting harder to keep in control. The car also shifts at 2 rpms and feels like its jerking. Has been taken in for alignment 4 times and the dealerships refuse to inspect or fix car. The toe specs are constantly being thrown out of spec in less than 4 weeks when hitting bumps the steering wheel shifts and stays shifted. It is harder to turn left than it is to turn right.*dt consumer stated she now has a bent strut and manufacturer told the dealership to release the car until consumer settled the claim with her lawyer.*jb*dt*dt*jb consumer state

Tl* the contact owns a 2019 Infiniti q50. While operating the vehicle, the predictive forward emergency braking feature malfunctioned and the vehicle would not stop or slow down when a second vehicle stopped ahead. The vehicle was taken to competition Infiniti (587 middle country rd, st. James, ny) to be diagnosed, but the cause of the failure could not be determined. The manufacturer was notified of the failure. The failure mileage was 300.

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.
