This time, the suv fluttered so the front camera lights and front collision lights came on... I took it back to the dealership and it was shaking after gear shift to 2nd. They replaced the valve body upper and lower program TCM Latest Cals code 1822376759 reset shift adapts with scan tool...

It took a week, and picked it up yesterday and will take it back in for same fluttering at gear shift Monday. From June 17th until June 21st, 2019.

Update from Aug 12, 2019: The third week back to the dealer was a charm... Torque converter was replaced... it stopped the fluttering at the changing of gears.

We had noticed a jerky transmission from the purchase of this car. No information was given to us about faulty transmissions or gear problems. I have had multiple problems with this vehicle but I will only mention the transmission issue here. We got an estimate on May 14, 2020 because the service center said that the transmission needed to be replaced. The estimate total to replace the transmission was $5524.12. As you can imagine, we never dreamed that we would have needed to replace the transmission. This vehicle is practically brand new in my opinion. It's barely 5 years old!!! I am not sure where we are supposed to pull that kind of money out of thin air.

We paid this vehicle off, with extra payments and hard work, about a year ago. We will need to get a second opinion on the repairs and have not done so yet. Life has to go on. I want to dump this heap so badly and get something I can rely on like a Toyota. This could have been the first time we had a vehicle paid off, had no payment and could have possibly relied on driving it another ten years without much more than maintenance upkeep. If we had a Toyota, we most likely would not be having this problem. Even if you account for the repairs, we would be paying less than if we bought another car and had to pay interest for 5 years on the loan for another car. I don't want another loan!!! SO FRUSTRATING!!!!

After picking up our new truck we noticed that the vehicle's engine was short jumping at low speeds, especially when in traffic. After only a couple weeks of ownership we dropped off our new vehicle to be repaired. Dealer 's GMC certified technician had to consult with GMC corporate to help troubleshoot and then decided to replace the lower and upper valve covers which was a quick fix that lasted a little over a week. Now our brand new vehicle is once again a lemon and repeating the original issue.

After contacting GMC and after requesting another new vehicle since its common sense that a brand new truck should not have any internal engine problems; GMC corporate response was "don't you think that 1 car in 300,000 would have an issue"... that's a sad response since I would imagine that replacing 1 out of 300,000 would not even phase their bottom line - at the end we are not talking about a loose belt or wheel out of balance, but an internal problem which there tech told my wife that he could not guarantee that the care was safe during his test drive.

The dealer's manager response was "the car is not our problem when it leaves our lot", it then falls under the manufacture warranty; which makes sense, but once again we are talking about a brand new car, not a car that has some usage. Shame on me for allowing my family to purchase an American car from a company that has to heavily discount there vehicle to show value, and compete for market share, and also, a company to worried about their bottom line. It has now become obvious to me on why they failed and went bankrupt.
