2024 Chevrolet Traverse Power Train

2024 Chevy Traverse transmission failed at 5,200 miles while exiting a major interstate. Vehicle struggled to downshift and switch gears. Transmission fluid leaked excessively while driving and parked. The vehicle was not drivable after failure. Unreliable and clunky acceleration and slowing down put passengers, including children - especially those in the rear-most seat - in danger. The problem was confirmed by the dealer. No further inspection outside of the dealership has occurred. There were no warnings prior to the failure or even during the failure. It wasn't until 20 minutes after the first observation of unusual handling, when an attempt to put the vehicle in reverse was made, that the notification was on the dashboard. When starting the vehicle 18 hours later to take a photo of the exact mileage, no alert was on the dash at all.

My 2024 Chevy Traverse is leaking coolant within the radiator hose system. While driving on a busy interstate, the vehicle went into protective limp mode reducing acceleration, creating a dangerous situation for myself to manage. A check engine light did come on with the reduced acceleration notice. I am having to add coolant to the vehicle constantly to drive it. Parts on our national back order now due to the huge influx of others experiencing similar issues. Dealership has confirmed leak - however I’m told it is not covered until manufacturer warranty and can be costly to repair!

I had my upper radiator hose leaking coolant after only owning this brand new vehicle about a year and half. Has less then 20,000 miles on it. I was able to get it into a Chevy dealer and they confirmed the leak. Seems the original part was defective. Was told I could take it home and drive it until the part came in(no eta on that) but to monitor the levels of coolant. Within two days I had a huge puddle of coolant in my driveway and had to bring it back to the dealer immediately. Thankfully I had coolant on hand and was able to refill the reservoir to make it to the dealer. This is a big concern because this is my wife’s car that she uses primarily to transport our two young children around. Thankfully she didn’t get stranded somewhere.

FLUID LEAKING FROM BOLTS ON TRANSMISSION REQUIRING FULL REPLACEMENT

We were driving on a street and the vehicle suddenly just stopped. We could not get it out of park. We could not get into neutral it would not shift into any gear and it said transmission needs service. That is such a dangerous thing because luckily it wasn’t a busy street because it just stopped in the middle of the street and we waited there for an hour and a half to get a truck to tow it off

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.

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.

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.

With only 1017 miles on vehicle, the transmission leaked all of the fluid out. Incident happened on a side street, thankfully not on the freeway as this would have been even more of a safety concern. Vehicle was sent to local dealership for inspection. NO warning lamps or messages appeared before, during or after the transmission fluid leaked out of the vehicle.

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.

The manufacturer was contacted and opened a case, but no additional assistance was provided. The failure mileage was approximately 2,200.
