My 2023 GMC Sierra 1500 slt 4wd currently at 67659 miles was taken in to the dealer because of excessive jerk when accelerating or trying to reverse, diagnostic scan failed for check engine and abs trouble codes. The scan return code po747 indicating transmission pressure control solenoid “a” was stuck on for a predetermined period of time. The recommended repair is replacement of automatic transmission, solenoid control valve body. I’m aware that gm has issued a TSB 25–na-255 and special coverage n24245441–02 addressing this exact failure on the gm 10 speed and that gm previously issued a related recall n242454440 addressing this exact failure on the gm 10 speed transmissions, and that gm previously issued a related recall for this citing rear wheel lock up risk associated with transmission valve condition. My vehicle scan showed an abs failure at the same time as a transmission. Code, consistent with the safety risk. Gm has already acknowledged and its own recall documentation however I was told to contact NHTSA to document the safety risk and request investigation of the scope of this defect across affected models years and vehicles as mine seems to have fallen short. I previously owned a 2021gmc vehicle same model that experience the identical transmission valve body failure that vehicle could not be repaired in a reasonable time and I ultimately experience financial loss and had to replace a vehicle now I’m experiencing the same defect on the vehicle purchased (this one) with significantly fewer miles than would be expected for a major transmission failure, indicating that this may be a reoccurring manufacturing design defect rather than an isolated incident. Thank you for your time and I hope this issue can be resolved as I do love the truck otherwise however safety first. Thank you.
At 12,018 miles on my 2024 GMC Sierra 1500 I experienced a rear wheel lock up. I have 4wheel drive capability but I had the truck in rear wheel drive only. Thankfully I was not going fast at the time. I was going between 35-45 mph when experiencing the lock up. As I was going down a straight away, I experienced a rear wheel lock up of my 10l80 transmission. My tires were squealing like crazy. I pulled off onto the side of the road. After shifting to reverse and then park and then drive the problem corrected itself. When I brought it into the dealership, they could not find anything wrong with it. Additionally my trucks software was up to date and not lacking any updates. I don’t drive this truck very far and only drive about 150 miles a week. A rear wheel lock up of this magnitude at this low of miles is concerning. I’m not rough on the truck by any means. It’s more so a family vehicle than a hauler. I have got the truck serviced 3 times since I bought it for regular maintenance so that’s not an issue either. There were no warning indicators that this problem was occurring when I experienced the rear wheel lock up. This could have resulted in a collision with vehicles around me if I had not been aware of what was occurring.
I was driving at approximately 25-30 mph, accelerating from a stop light and I felt a clunk, heard a grinding noise and my back wheels locked up. It was snowy/icy conditions so the back end of my pick-up slid out to the right a little bit before the wheels unlocked and I was able to regain control. I could have slid off the road or into another vehicle had the wheels remained locked. The computer system then alerted me to a transmission issue and to reduce speed immediately and call for service. The pickup was then unable to shift out of 1st gear. The vehicle has been towed to a dealer and I have been informed the valve body in the transmission has to be replaced which is 8-12 weeks backorder.
