INFINITI Q50

Affected: Steering/Electrical/Direct Adaptive Steering, 50K miles While driving my 2017 Infinity Q50s under normal driving conditions, the vehicle suffered an instantaneous, catastrophic, and total failure of the power steering assist system without any prior warning or dashboard fault indicators.

Had 2 new tires installed on the rear of the car and they both busted at the seam. Shredded the tires and damaged 4 wheels.

Something happened to cause power loss. I checked the recalls and work that was supposed to be performed but didn’t get done like it was supposed to. I need to have it checked now asap! I see 2 engine replacements and also the turbos and 2 of the catalytic converters. The last 2 need replacing as well or it’s not going to be right.

The valve body on these cars are useless. Driving down a highway and cant shift out of 3rd gear almost had a car re-end me. Today I am driving and the ECU is not responding I see the check engine light on then I'm like not again. This would be the 3rd valve body I replaced.

The backup camera in my vehicle intermittently fails to display an image or presents a blank or distorted screen when the vehicle is placed in reverse. This defect significantly…

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…
