Example complaints

“I have a 2011 chevy 2500. 6.6 turbo diesel at 136k miles. My def heater just went out and my dealership said it's only under warranty until 120k miles. I've been looking online and there's a lot of 2011s that are having the same problem. Someone needs to step up and be responsible for this. It's costing me $1200 to fix plus a day off work. I'm self employed and if I sell a faulty product I'm required to replace for free. G.m should be doing the same.”
NHTSA complaint #11306829, filed 2020-02, 136,000 miles“Exhaust manifold bolts are breaking despite regular non commercial use and proper maintenance. This causes an exhaust leak and I am not comfortable driving my infant in the truck now. Dealer says 4 how odd labor plus parts so approx $1000 fix? That's unreasonable for any motor but especially under 120000km.”
NHTSA complaint #10908343, filed 2016-09, 78,000 miles“Traveling at 60 miles per hour, accelerated and the accelerator stuck going up to 80 miles per hour in a 60 MPH zone. I stomped on the accelerator to no avail. I had to put the truck into neutral to avoid a crash. Pulled over and finally kept stomping the accelerator until it released.”
NHTSA complaint #10543673, filed 2013-09, 36,000 miles“I was traveling to work in the fast lane of the freeway when I heard a faint squealing noise and the truck suddenly started running rough. I began crossing all 4 lanes and by the time I made it to the the slow lane the truck completely died. I was able to safely coast off of the freeway due to my quick reaction and lack of traffic at the time, but the situation was very dangerous and could have been much more so with heavier traffic or a less aware driver. Later diagnosis at the Chevrolet dealership told me that the cp4 fuel pump disintegrated inside. …”
NHTSA complaint #11150932, filed 2018-11, 54,000 miles“Battery needed to be jumped off. Jumped off battery and then decided to go and purchase a new one. We were driving down the highway at 60mph, flames and smoke started coming up over hood. Pulled over, parked and jumped out and started throwing items out of vehicle. Called 911, but by the time they arrived, the truck was totally engulfed. It is a complete loss.”
