Example complaints
Brakes: “I was slowly backing up at a flat launch ramp to put our boat into the water. As the trailer reached the water, I pressed harder on the brake pedal. When I did that, the brake pedal went to the floor and the vehicle continued to roll backwards until the boat reached the water. Fortunately that stopped the vehicle from moving and allowed me to apply the parking brake. One of my brake lines had burst. The repair shop said the brake lines were all rusted and not in very good shape. …”
NHTSA complaint #10648287, filed 2014-10, 101,000 milesElectrical system: “2003 chevy SUBURBAN 2500 (3/4 ton) - the instrument clusters are junk and dangerously unreliable - faulty. It is absolutely criminal that GM and NHTSA not issue a formal recall on GM 2003-2006 instrument clusters. Mine began failing at 40,000 miles in 2005 (fuel gauge reading wrong or empty if idling more than 30 seconds, speedometer pegging or reading wrong intermittently). I mentioned this to the dealer but they lied and said that had no other reports of such. …”
NHTSA complaint #10218121, filed 2008-02, 40,000 milesFuel system: “I will be driving down the road both hwy and city. The suburban will go into reduced engin and lose all its power and speed. I have to pull over and cut the car off and restart it and it's fine to go for maybe a mile and it does it again. They can not pin point what the problem is . It's very dangerous.”
NHTSA complaint #10823383, filed 2016-02, 190,000 milesTransmission and drivetrain: “One of the metal brake lines between the master cylinder and the ABS modulator valve ruptured during a stop due to corrosion. All brake lines in the vehicle have similar levels of corrosion near the area the aforementioned line ruptured, and at various other locations on the vehicle. The transmission cooler lines had failed approximately 18 months previously due to corrosion. The corrosion and rust on many components beneath the vehicle and in the engine compartment is becoming rather concerning.”
