Top problems in owners’ words

Verbatim from NHTSA complaints, newest first

Engine

10 reports1 crash
“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.”
Owner complaint to NHTSAFiled Jul 8, 2026Vehicle speed control, EngineODI 11749209

Power train

6 reports1 crash
“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.”

Electrical system

6 reports1 crash
“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.”

Vehicle speed control

4 reports1 crash
“Vehicle is tramaling or wandering at 50+ mph speeds. Making it dangerously difficult to keep between the lines without constant steering corrections. I have had car aligned and changed the tires. Still issue persists. There are several post online about this issue with the infiniti Q60 and Q50 models.”

Steering

4 reports
“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…”

Suspension

4 reports
“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.”
