Example complaints

Brakes: “Brakes suddenly gave out. Pedal fell to floor and when I took it to be repaired I was told all the brake lines rotted out. I don't understand this because by vehicle was garage kept. My total bill was $875.00.”

NHTSA complaint #10586332, filed 2014-05, 170,000 miles

Body and structure: “Rear window leaked from day 1, reported to dealer, upon lease turn in it was discovered that rubber around window was cracked, they are now charging me for the damage.”

NHTSA complaint #10182073, filed 2007-02

Electrical system: “Chevrolet avalanche instrument cluster failures. Over the past 32 months the instrument cluster on my 2003 avalanche has been intermittently malfunctioning causing the speedometer, fuel, temp, oil pressure and all other gauges to not operate. As of 1/19/2008 all of the gauges on the instrument cluster failed completely. From what I understand Chevrolet has issued a extension of the warranty to 70,000 miles for this single issue but this is a safety related problem that should be taken care of under a recall of all vehicles with this instrument cluster.”
