Hi, I apologize in advance for this long post but I am honestly stressed out about this and don't really know what I should do.
I am in sales and my territory is in multiple states so I drive a lot of highway miles. I have a 2019 Sierra SLT with a 6.2L and pretty much all the options you can get on the SLT model. I currently have 116,000 miles on it. I have not been happy with this truck from the start because it has left me stranded multiple times.
1,200 miles the solenoid went out that allows it to come out of park and I couldn't shift out of park. - Covered under warranty
Trailer module was replaced due to lights not working. - Covered under warranty
I used the GMC app to start my truck once while I was out of town and my truck then had no brakes and went into limp mode. - Covered under warranty. Dealer said it was because of a bug in the software update.
Idler pulley needed replaced because it was whining really loud
In January this year when the truck had 112K miles on it my engine failed. It was a broken lifter which bent the push rod and damaged the cam. Not covered under warranty and the dealer said I had a choice of $6,000 to fix the existing engine or I could put a new engine in for $8,000. I opted for the new engine.
This took about 5 weeks to get back. $8K was to cover labor and everything. When I went to pick it up the bill was $9,400 and I was told that my oil pressure sensor was damaged in the changeover so I was charged for that, as well as they said I now needed a new fuel pump even though that was fine when my engine failed. That along with a $1,500 rental car bill because it's my only vehicle, I had near $11,000 out of pocket for this. I have seen the posts about the GM lifter issues and that is what happened to me but GM refused to help in any way.
I got my truck back and opened the hood. The factory wiring harnesses were just laying in the truck not clipped into the factory clips anywhere. The bolts that hold my air filter box and coolant overflow reservoir are completely missing. There is a bracket wire strapped to the wire harness that is just hanging there. There is a liquid gurgling sound from the dash which makes me think they didn't purge the air out of the coolant properly or something like that. That's all things that I could see at a quick glance, there are more I'm sure. But the reason I took it to the dealer and not some random guy down the street is because I wanted it done right and that wasn't the case.
I have 4,000 miles on the new engine. For the past few weeks when I start it it will stall sometimes. Then it would stall as soon as I put it in reverse. Then it was stall a few times until I get going but then be fine. Yesterday I went to the store and when I left the truck was running rough. It stalled multiple times leaving the parking lot and would surge kind of. When I was leaving it stalled as I was pulling out onto a major road.....I was able to limp it home.
I don't know what to do. I don't feel I should have these issues on a 2.5yr old $60,000 truck. I don't want to take it to the dealer that did the engine swap because I don't trust them. I can't afford to get another rental car for a month. I can't afford to keep putting thousands of dollars into this truck. This has been the worst experience of a vehicle I've ever had. My last truck was a 2005 Nissan Titan. I bought it new and sold it in good working order when I bought this truck. I had that for 14yrs, 430,000 miles and NO MAJOR ISSUES.
