2022 GMC Terrain Na

I had an issue with the All Wheel Drive system. The message Service all wheel drive system appeared as I was driving the vehicle. They found a rear differential module software issue 2810695. They found DTC C056D stored in rear diff control module. They programmed rear diff module and retested. Claim code is 1BYN199108119. I do not have any parts but I was told that they send warranty components back to the manufacturer for inspection.

On Aug 3rd 2023 I was driving east on a Michigan Highway when the service transmission warning came across the dash then the car shut off while driving 60mph. When trying to steer the car to the side of the road I noticed the car was in park(this car is equipped with push button shift). The car shutting off made it very hard to steer. If the traffic was heavy this could have caused an accident. I do have a video of this happening

April of 2022 I purchased this car brand new. January of 2023 this car started to have a musty/mold smell. I took it into the dealership in late February and inquired if this was a reported problem. I did as they dealership said and replaced the cabin filter. The cabin filter was black at 9,700 miles. It smelled horrible. On April 6, 2023, I took my car into the dealership to resolve this smell. It was discovered that the the cowl inside the firewall on the drivers side firewall had several holes and an incorrectly applied seam. It was also discovered that the drivers side sunroof drain was also disconnected. This was was full of mold. They replaced the entire interior of my car which took until June 28th. I expressed I did not want this car back for fear of mold, I had already been sick and had no idea why. Once I got into a dealer car, I quit coughing. The dealership cannot guarantee me that they got all of the mold in the car, it still has an odor in it. I have went through the claims process with GM and they have refused to buy back my car, based on my claim I am worried about my health. This car had $12,000 in repairs to it. I was promised verbally by the District Manager of After Market Sales that my car would be bought back. They backed out on the deal and told me they cannot buy it back for destruction. I have great concerns about my cars safety with the mold being so large. They cannot guarantee me the mold is completely gone as told me to by the Service Manager. Therefore, this would include the safety of others that travel in my car, to include children and older adults. This problem started in manufacturing and was acknowledged by the dealership as such. It was a defective car when it arrived on the lot.

Vehicle started stalling back in February 2023, service engine light started coming on and then we started getting a message that the SD memory card had been removed and this message has stayed on constantly along with the service engine light. I made an appointment to get the recalls fixed with the dealership that we purchased it from which is 50 miles away but was told the parts for the fuel pump and child restraints were not available at that time. They looked at the memory sensor card but could not find anything wrong and was told if the error message came back up to call them back, I know more got home and the message came back up so I called them back and they set me up with another appointment the following week. This time because the message only comes up randomly and it did not come up while I was there I was told nothing could be done but to call back when the message comes back and as soon as I got home it came up so I called them back, they made another appointment for the following week and this time the message came on when the tech drove it so they took out the sensor card and cleaned it and everything around it and said everything looks fine now but it still comes on, but was told due to them not having the parts for the fuel pump that we should take it to our closest dealership. On 6/15/2023 we took it to our local dealership and I was told they would need to order parts and the eta on it was 4 days out, they said they would call me when the parts came in, I waited until 6/22/23 and no one ever called me back so I called to check and the parts were still not in but would check on it and call me back, no one ever called and I still have not heard from anyone. The last time we took it up there the vehicle stalled, we almost got hit from behind and it kept dying and would barely start, it is now setting under my carport, we are afraid to drive it and I still have not heard from anyone.This all started in February 2023 and it is June now.
