The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights.

Starter Generator Failed on 10/12/2023 while the car was being driven. Warning received was "Electrical system: Malfunction!

While parking the car, the gearshift got stuck in “Neutral” even though N was not pressed. I was not able to restart the car once I turned it off. Every time I pressed the start button, a warning would come on the screen “ please put the vehicle in Park. Risk of roll over”. When I pressed the park button, nothing would happen.

The MMI/ radio shuts off and reboots at least every 5-6 minutes. When it comes back up, I get the error “user hasn’t been detected for some time”. Every time it shuts off it is 30 seconds to a minute where nothing in my MMI is accessible. This began around late June of 2025. No warning lights or error codes have been found.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.
