POWER TRAIN, ENGINE
Engine Seized up on me while driving on the freeway. Four of the crankshaft bearings seized up and one of those four completely melted. good thing the freeway I was on was not too crowded, my dash just all of a sudden lit up saying shift to neutral to restart engine. I was able to get to the shoulder. I tried re starting the engine and nothing happened. I had it towed to Simpson Chevrolet in Irvine CA. they reported back to me and said Engine has seized and I will need a new engine, cost of $16,893. I cannot afford a new engine right now and have been left without a vehicle. GM has taken no responsibility for this failure even though all maintenance has been performed on time every time.

ELECTRICAL SYSTEM
The rear power tailgate was randomly opening and closing on its own, on several different occasions. The safety risk was, if the tailgate would have opened when traveling down the roadways, items in the back could have fell out and possibly striking another vehicle and causing an accident. The truck has been taken to Gandrud Chevrolet in Green Bay WI, confirmed there was a faulty tailgate switch and replaced. There was no warning before the switch failed, it just happened on its own.

ELECTRICAL SYSTEM
The tailgate is opening automatically without anyone near the vehicle or keys. It has only started recently and I see similar vehicle models are being recalled for the same issue. My concern is that this could happen while driving down the road, posing a risk to other drivers if there are items in the bed of the vehicle. Prior to the tailgate opening unexpectedly, the button to push on the tailgate that opens it quit working. It will only open with the keys or button in the cab, or now at random times.

STEERING
51,000 miles and Power steering warning light came on, attempted to turn and the wheel and was a struggle to make a turn. I almost ran off roadway and struck a tree. I struggled to get the truck home, where it sat for a minute and reset itself and worked properly for now. Upon reviewing the electric steering in this year, make and model was very common within 15k miles to 65k miles. Upon internet search, revealed this problem had a recall. Wanted to make sure before a manage to transport the truck for service at dealership and pay for high labor charges.

UNKNOWN OR OTHER
Since the purchase of this truck I have been having the same issues consistent with the current recall. It has gotten worse and has almost caused an accident during acceleration due to skipping or locking up of the engine/wheels. Worse when traction control is on. This Happens almost every time the gears shift during acceleration.

ENGINE
The first time it happened my Truck started shaking a lot on the highway and it left me stranded on the side of the road. It had around 20,000 miles on it. When it got repaired I was told it had to do with the lifters on the left side of the engine. Took them 2 weeks to fix the issue. The second time it happened was on the ramp getting on to the highway, this time at 58,000 miles and now the right side lifters. Except this time they couldn’t fix it and they are going to replace the whole engine and give me a new one. Only thing is that it's been in Chevrolet shop for over 2 months and they have an ETA of a new Engine arriving in about a month if even that. So currently don't have my truck.

POWER TRAIN
While coming to a stop at the end of the exit ramp my vehicle bucked when trying to go from a stop into 1st gear. Eventually the truck continued in a forward motion. Then came to a stop light and once again from a stopped position by truck bucked and eventually went into gear and continued forward motion. Parked the car where it sat for 1.5 hours then went to drive the vehicle and it bucked again into 1st gear. Drove to a parking lot were we parked to get lunch. Came out started the vehicle backed out of the parking spot and drove forward to the exit of the parking lot. When trying to exit the vehicle failed to move forward. The car acted as if it was in neutral and only revving to high RPM's. Removing the fuse for the Transmission Control Ignition allowed the vehicle to move forward but only in gears 1,2,3. I brought the vehicle to GMC dealership and they recommended a fluid service to determine if metal chips are in the fluid. That service was performed and issue remained. The Dealer has recommended a complete transmission replacement. My vehicle never displayed a warning lamp or shown symptoms prior to this failure. My vehicle has a 8 speed transmission which is known to be a failing part with Chevrolet and GMC. A new transmission is costing me $7900 plus tax on a 2021 with low wear and highway use.

ENGINE
Around [XXX] on [XXX] the vehicle shut down with no codes showing or any warning. The weather was approximately 13* f. After many failed attempts to restart, and the electrical systems would not power down as if the vehicle thought it was still running. The only way to get the system to shut down was to disconnect the battery. i had to physically push the vehicle to a safe location. The next morning I attempted to diagnose the issue with no success. I had the vehicle hauled to the dealership from which it was purchased in Idaho to have it inspected. Tuesday morning I received word from the dealership that the engine suffered major failure. This will be the 3rd engine in the vehicle. I am uneasy about the dependability of the vehicle as I have recently discovered that this particular engine is having massive failures all over the country. So much so that the NHTSA has opened an investigation for the purposes of safety. I purchased the vehicle for the main purpose of pulling a snowmobile trailer with snowmobile to the mountains and also to tow my boat and trailer. Both of these activities require a vehicle in which I can depend on. While I am waiting for a back order engine the dealership and manufacturer refuse to lend a like vehicle, leaving destitute. I am hoping that this agency can offer some assistance, and I believe it's important that you are made aware of the hazard that this particular engine possesses. As I previously mentioned this the 3rd engine and As far as I can see this will occur again putting myself and others potentially in harms way because of a known issue. This does not make me feel confident of the safety of the vehicle. Be aware where i live there grades in every direction and extreme weather conditions from season to season.

POWER TRAIN
Drove my truck home for lunch. Truck drove normal all morning with no warning lights or audible warnings. Went to leave and head back to work. Put my truck in reverse and it would not move. Still no warning lights or audible warnings. After looking online it said that this was common in the Chevrolet speed transmission. It also says the valve body was bad. They also stated that it could lock up the transmission and cause an accident. Luckily I was not driving down the road to find out. When talking with a Chevrolet dealership they told me that the parts to fix the transmission is on backorder. They also stated that the parts may not be available for months. Because the Chevrolet dealership had other Chevrolet vehicles in with the 10 speed transmission with the same issues and could not get parts because of the valve body being on backorder. They also said that the whole transmission being on backorder. This sounds like it's a common problem with Chevrolet 10 speed transmissions.

STEERING
I was driving and my electric steering locked up. I had it towed to a garage and they reset the computer. I'm afraid it's going to happen again. I'm going to the dealership on Tuesday and I don't feel that I should pay for this since it's a safety issue. I only have 50,000 miles on it.can someone please get back to me. Thanks
