Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Exhaust manifold bolts are broken off on both sides of the 6.0 engine, causing exhaust fumes in the passenger compartment when I driving the vehicle. I have owned this vehicle since new and have never had any engine work done to this vehicle.”
NHTSA complaint #11165902, filed 2019-01, 40,000 miles“Gm mad a faulty bolt design and no one is holding them accountable. I have 3 broken manifold bolts and the dealership wants $2100 to repair. There are thousands upon thousands of others just like me who are helpless. Why are you and the epa doing nothing? The vehicle can't pass emissions like this!”
NHTSA complaint #10716594, filed 2015-05, 147,000 miles“Upon starting my truck, the oil pressure gauge immediately goes to 80 with no acceleration. At this point, there is no noise or other lights coming on to warn of other problems. This problem started a few days ago. When truck is in motion the oil pressure gauge continues to stay on 80. I know the 2006 chevy 2500 heavy duty 4x4 have had recalls on different things, but need to see if this is a problem for other chevy trucks as well. I have read several recalls about these trucks and a lot of them we have never been notified to take it to a dealer to be checked. …”
NHTSA complaint #11073907, filed 2018-02, 100,000 miles“Transmission slipping, banging periodically 1,2,3 gear and down shift. Transmission gauge red-lined, now is not properly showing temp. Oil gauge is moving 0 to 80 all the time. Some lights have been going out on panel and steering wheel. Check engine light on and off. Transmission company diagnosed as a possible electrical issue and chevy states the transmission bang and slip is common and no repairs are needed? Help.”
NHTSA complaint #10690494, filed 2015-02, 71,000 miles“Vehicle under carriage looks more like a 30 year old vehicle. Brakes lines have failed causing extended stopping distance or swerving off road to avoid collision. Oil cooler lined ruptured and leaked oil on exhaust manifold, a potential fire hazard, especially when all the exhaust manifolds rotted as well so hot exhaust gases are not directed out the exhaust, also a concern for poisoning occupants with toxic exhaust gases . Power steering fittings rotted causing loss of steering. Gm is useless, when I contacted them they said it is the environment. …”
