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.

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. After speaking with the diesel technician at the dealer I learned that it is a very common problem and the repair comes with a $10,000 price tag. I was also very surprised that there has never been a recall for this problem and gm continued to use them until 2017...7 years! My truck is a 2011 with only 54k miles, and they just fixed a 2017 with only 7k miles! I have since done a lot of research finding hundreds of low mileage gm duramax diesel between 2011-2017 with the exact same failure. I was able to get the bottom of the failure itself and I found the following...the bosch cp4 fuel pumps that were used in these trucks (also found in late ford and vw diesels) are made in europe to different specifications. The pumps rely on lubricant found in diesel #1 to operate smoothly and last a long time. Here in the u.s. We only have diesel #2 which lacks that lubricant and causes the internal parts of the pump to disintegrate sending metal shavings throughout the entire fuel system. This is why the repair averages $10,000 across the country, the entire fuel system becomes contaminated and has to be replaced. I contacted gm and they don't believe this is a safety issue. A vehicle suddenly dieing with seconds notice on the freeway is certainly a safety issue in my eyes. Especially when it's a common failure that can be prevented.

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.

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.

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.

The truck had the check engine light come on when we took it to the dealership they replace the fuel pressure regulator. The light soon came back on due to a faulty fuel pump which sent the car into safe mode, which made the car do a nose dive from 55 to 15 in a matter of seconds on a major interstate in atlanta.
