In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Instrument cluster has continued to fail. Called local chevy dealer, because truck is over the mileage it is no longer covered by recall that i was not informed of. First oil pressure gauge quit then speedometer failed. Chevy has known of the problem and should be held accountable to fix this problem.
-
Was driving about 60mph and speedometer went to zero then wouldn't go past 15mph after that. Sometimes it works and then not.
-
Service brakes, hydraulic:foundation components:hoses, lines/piping, and fittings corriosion from front to rear on all above.
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 30, 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.
