In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Transmissions will not shift out of 1st gear. And puts out a 752 code. This can happen at anytime. Vehicle will suddenly lose power at any time.
-
The Car has over the last few years not turn off due to shift to park. This is concerning, due to we cannot turn the car off unless we strike the shifter few times assuming this is the remedy. It doesn't look like there is any type of recall but there should be.
-
There is a water leak problem with the Acadia ! My car had a dead battery and when it was time to change the compartment was full of water I also get water under steering wheel.
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.
