In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
I got this vehicle and have had the body control module replaced 3 times the first time was as soon as it got out the dealer lot the turn signals were not working so I took it back a week later and they had to replace the body control module and since then they have replaced it 3 times

Your site shows no recalls. I got a recall for a repair I had to have done a few months ago. I just got the recall notice from GM, but when I called to inquire about a reimbursement, they state the recall was released in 10/2025. Even though your site says there was no recall at the time.

When trying to back in garage, transmission would not go in reverse at all and can only move forward, at times, the navigation display screen will turn off or freeze before operating normally, and the brakes have been squeeking ever since it was driven off the car lot when purchased new; GM says that's normal.
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
