2024 Chevrolet Traverse

The contact owns a 2024 Chevrolet Traverse. The contact stated that there was fluid leaking from the vehicle onto the driveway. There were no warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed that the transmission was leaking transmission fluid. The vehicle was not repaired. The manufacturer was contacted and opened a case, but no additional assistance was provided. The failure mileage was approximately 2,200.

I was stopped at a red light in rush hour traffic in the middle of three lanes. When the traffic light turned green, I pressed the accelerator and the engine revved, but the the vehicle did not accelerate in a normal manner. The CEL came on in the DIC along with a message "Reduced Acceleration. Drive with Care." I was able to slowly change lanes and turn into a parking lot while cars maneuvered around me to avoid a collision. I was unable to exceed 10mph while surrounding traffic was moving approximately 50mph presenting a safety hazard. Per an Onstar On-Demand Diagnostic scan, the PCM indicates a P0746 code. The vehicle was towed to a nearby dealer. The dealer indicated the transmission will be repaired under warranty. There were no warnings (slipping gears, rough shifts) prior to the incident. The vehicle has less than 3200 miles on it.

With 103 miles on odometer, vehicle check engine light illuminated, warning message appeared on DIC regarding reduced acceleration, then vehicle proceed to downshift causing the vehicle to reduce speed dramatically almost causing the vehicle behind to hit my vehicle. Vehicle now does not shift properly and is at over 4500 rpm, while driving at a speed of 55 mph.

The transmission suddenly failed on this vehicle. I was later informed that it was the clutch piston. Fortunately, the failure occurred at a stop light when I attempted to accelerate from a stop. The vehicle initially did not move as expected. If this had happened when turning into traffic, or merging onto a highway, it could have been dangerous. There was no warning light or indication at first. The service engine light only came on after about two miles. I was able to drive the car but accelerating was very slow. This car was purchased on [XXX]. I am seeing some documents online that indicate GM knew of this problem, and the dealer possibly should not have even sold me this car. As of this date, the car sits at the dealer with no replacement parts available. I took the vehicle to Phillips Chevrolet in Frankfort, IL. The representative there is who told me it was clutch piston that failed. There was never any warning or indication. This problem occurred suddenly.

Transmission issue: Dealer was not able to replicate issue due to it only happening periodically. When putting into drive mode and going to accelerate it feels as if the transmission is slipping and give a big jerk. Also will sometime make a loud noise like tranmission is "dropping". Or when foots off gas peddle after going at a steady speed then go to accelerate again it will jerk. Dealership said that is normal as there is a "learning phase" which I've owned several new vehicles n never experienced this before. No warning lights have been shown. Reverse automatic breaking issue: Several occasions while reversing vehicle will slam into park mode when nothing is behind me. Brought to dealer, dealer said to shut off the notification. However, I don't want to have to shut it off. Tech did experience this once while attempting to reverse vehicle. But service advisor said there is no fix for this issue. Very startling to anyone in vehicle when it quickly locks up.

On May 14 a service bulletin was released by GM for an issue with the transmission #N242446290 causing a reduced acceleration suddenly and finally zero acceleration after a few minutes unexpectedly. I purchased this car brand new on [XXX] and was not made aware of this potential problem. On [XXX] we took a family vacation road trip from TX to Gatlinburg, TN. The transmission failed and the engine gave zero acceleration the night of [XXX]. I had to have GM roadside tow the vehicle to a Chevy dealer there in Tennessee and then rent a car out of my own pocket to drive home. This is a safety hazard for sure with the vehicles listed on this bulletin as it gives no warning of failure while driving. I was pulling onto the road with traffic when the engine light came on and I lost all power, unable to move out of the way.
