This Problem Across All Years
This vehicle had 19500miles on it when we picked it up at the airport rental agency. It was 2WD model. We used it for 2200 miles on a family vacation and 95% of this was interstate highways. Smooth road surfaces. The travel conditions were sunny hot, dry. There were 6 passengers and a decent amount of luggage. Rear cargo area still had foot or more of space though so it was not stuffed like for a beach trip. At one point after getting on the highway from on ramp, there was a horrible sound. It got louder and louder quickly and caused us to panic. My husband looked in all the mirrors. He said it sounded like a Peterbilt semi was barreling down on our ass. But there was none in the mirrors. He quickly let off the gas pedal during this and the sound went away. As we sped up again though, it did the same thing and this time even louder. Starting around 72mph. Something was resonating in the body or powertrain of the car and it seemed like it was about to come apart! We did a check quickly, all of the windows were completely up, the AC was on. The radio was off. He slowed back down, the sound went away. But for 3rd time of trying to reach 75mph, the whomping sound came back and was so intense, it was debilitating and he almost could not hear me talking. We didn't know what to do. He braked immediately to pull off to the side. On a busy highway. After we stopped he got out to look at the tires but we did not a have tire pressure gage. They seemed perfectly normal. He looked under car, in wheel wells, opened the hood with the engine running, shook the car from side to side. Nothing was found loose or hanging down. After this, we could hear the same type of sound at 54mph, 60mph, and between 72-77mph , it all came down to what RPM and gear the transmission was in. This seems like a total design flaw in the chassis or power train. We told the rental agency that no one should be using or buying this car until the issue was fixed.

After owning the vehicle for 13 short days, the check engine light came on and a message appeared indicating the vehicle could not be put in reverse due to unsafe vehicle condition. The vehicle just hit 500 miles at this time. Brought vehicle to the dealership 7/14 and it is still there diagnosed with needing a valve body for the transmission which is on back order and no estimate on when it will be available.

The transmission system on my 2025 Chevrolet Traverse began showing signs of failure approximately 2–3 months after purchase. Symptoms include erratic shifting, gear hesitation, and sporadic power loss while driving. Although the issue was promptly reported to Chevrolet headquarters, I was unable to bring the vehicle to the dealer earlier due to the lack of available loaner vehicles. The car is now at the dealership and has been there for nearly three weeks without any updates or contact from the service team. The transmission is available for inspection, and documentation of the issue exists. The malfunction has created safety risks during normal driving, including delayed acceleration when merging into traffic and unexpected gear disengagement at speed. These conditions compromise vehicle control and increase the likelihood of a collision. Additionally, the vehicle produces a persistent squeaky noise from the accelerator pedal during operation, which could indicate underlying mechanical stress or a deeper linkage issue. The sound is both distracting and concerning, especially during highway driving or sudden acceleration attempts.

Brand new Traverse with 3,600 miles on it started leaking transmission Fluid. Was told by dealership it was a slow leak and it was ok to drive while waiting for parts to come in. 12 hours later while wife was on highway coming home from work check engine light came on and vehicle went into low speed mode. My wife was able to drift off the highway and come to a stop. There was a puddle of red fluid under the vehicle and the undercarriage and rear of vehicle were covered in transmission fluid. It was towed to dealership on 02/14/25 and we are still awaiting status of the repair.

Hi, I purchased a 2025 Chevy Traverse High Country back at the end of November. It only had 2200 miles on it when my transmission started slipping. I was really enjoying this SUV too. On January 13th I noticed something weird happening when I would accelerate. When I would accelerate if felt like my tires were slipping on ice followed by a jerk. I knew it wasn't ice after accelerating at each stop. This worried me because my 10 month old son was in the vehicle with me. I was worried it was going to stop mid traffic. I drove it home and called the dealer and asked them to get me a loaner ASAP because the Traverse felt unsafe to drive. Luckily I got a loaner that same evening after dropping it off. When I returned home I saw the tranny leak on garage floor. A large reddish pink puddle. It's been in the shop since Monday. The Service department is trying to find parts to repair it. According to them they won't be available from GM until February 28th, unless they find it elsewhere. According to them it needs two bolts that are backing out of pump causing it to leak. Cars been in the shop now 11 days and counting. This is a big safety concern that needs to be made aware of to the public. People are purchasing this vehicle without knowing there's possible issues with the transmission. There definitely needs to be a recall on this transmission until they figure which ones are affected by this problem.

I was driving down the interstate in 3 lane traffic at approx. 70MPH. Car had 1,700 miles on it at the time. Engine abruptly reduced power and the RPMs shot up to 6000. It was a struggle to not get rear ended and get to the shoulder. With cars on either side this could have been a very different outcome. Upon getting to the shoulder the car would no longer go into gear. Dealer diagnosed it as a transmission failure and would need a new transmission. There was transmission fluid all under the car.
