2024 COLORADO TB purchased new on [XXX]. About 3 days later with 150 miles logged parked in my driveway I noticed OIL spots and leaking. Drove to dealer and they kept it for around 3 days. Dealer contacted GM to supply data points and information. GM had a bulletin placed for REAR MAIN OIL SEAL AND GASKET failure they attributed to faulty parts from original plant inside U.S. Dealer received authorization and billed warranty pulled tranny (allegedly) and replaced rear main oil seal gaskets to stop leaks. Had truck back in 3 days with much pressure and calls noting it was a brand new truck. A few quirks and lights I'm monitoring NOT related to this noted issue stated. GM was attempting to determine how many trucks these faulty gasket seals affected. Dealer was good about providing rental free and turned truck around quick. Extremely odd and quirky for brand new truck with 150 miles logged but I guess things happen it is what it is. I read all the other blogs and statements noted here so I wanted to include this one.

2024 Chevrolet Colorado transmission complaints
Page 2 of 2: complaints 11 to 13 of 13, newest first, as owners wrote them.
I bought a 2024 Colorado Trail Boss on May 31 and after a week the truck broke down I made a stop in a T intersection, once I had a clear path I started to accelerate and in that moment the truck jerked and at the same time I heard a loud noise under the back of the car. It felt like if I had been accelerating in neutral and suddenly changed gear to drive. After that, the car continue moving but after a few seconds the truck started to lose power and going super slow I tried to accelerate but the truck did not respond. I was able to pull off the road and stop in a parking lot. after that the truck no longer moved forward or backward regardless of what gear the car was in...the car didn't move again. he truck was towed to a Chevrolet dealer, and after two weeks, the service advisor informed me that the issue was with the transmission valve body. When this happen my family was with me in the truck, Luckily, nothing serious happened and I was able to get off the road.
I was driving the vehicle up a mountain, in a 70m speed zone, when the dash board lit up. The vehicle started to decelerate, I pushed the gas petal but it just decelerated. I put on the emergency light and continued to the exit. Stopping in Liberty Pa, at an Exxon station. Called GM roadside assistance. On-Demand Diagnostics stated: ECM-Engine System code P00700. TCM P0658, TCM P2729, and P281D. Odometer reading 3840. Remaining oil life: 49%. Our safety was compromised by the unexpected deceleration of the vehicle and possibly being stranded on the road. Was luck to get off the highway safely. The car was towed to Jack McNerney Chevrolet, Inc. 363 NYS Rt13, Tully, NY 13159 +13156968976. The car has been at the dealer since the night of [XXX]. Have been told that the car is not drivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
