Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I have a new GLS450 and on two separate occasions the car has shut down at a stop with no warning. First time was approximately mid July of 2023 with about 1,700miles. While at a stop the instrument panel displayed a text box with the words “Malfunction” across the screen, and proceeded to shut down. After a minute we were able to restart the car. Took it back to the dealership and they were not able to get any codes or reason why it happened. Now 3 weeks later it happened again, and back at the same dealership from where I purchased it. …”
