Power Train Problems of Chevrolet Traverse - part 2

The transmission. It is disengaging while driving down the road. It literally has basically stalled out in the middle of intersections, the highway, etc. There is a recall for this exact problem just not with my VIN for some reason. I tried to get a dealership to look at it and see if they can fix it they say they will not. I am not safe nor are others with this malfunction.

On [xxx], my 2019 Chevrolet Traverse (VIN [xxx] ) experienced a complete transmission failure. The vehicle began to hesitate, jerk during acceleration, and then completely lost the ability to shift or drive. It had to be towed, and the dealership confirmed that the transmission must be replaced. This is extremely concerning because gm previously issued recall 20v668000 involving missing bolts in the start-stop accumulator of the transmission, which can cause fluid leaks and loss of propulsion—a potential safety hazard. Although my VIN does not show this recall as active, the symptoms and failure seem directly related to this known defect. I am requesting NHTSA investigate whether this recall should be expanded or reopened to include more affected vehicles. In addition to the transmission failure, I have had to replace the purge solenoid valve three times due to persistent check engine lights and fuel system issues, which suggests deeper reliability issues with emissions and vapor management. Lastly, there is now a hole in the exhaust pipe, which is affecting performance and may pose a safety or environmental concern due to potential carbon monoxide exposure. These multiple powertrain and emissions-related failures within the same vehicle raise serious concerns about the long-term safety, reliability, and manufacturing quality of the 2019 Chevrolet Traverse. I respectfully request that NHTSA investigate this model year and VIN range further. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

Transmission shudders at low speeds changing gears. Less than 79,000 miles and changed or flushed transmission 3 times at dealership. Vehicle has been at dealership over a month with no fix in sight.

Vehicle started to show error for shift to park. Not able to shut vehicle off. Vehicle drives fine but when I go to park and vehicle is in park. I go to turn vehicle off and error appears. I called dealership according to them just to look at vehicle its going to cost me $275. . For everything else $1,100. After reading all the complaints on this issue why has manufacture done anything. Obviously this is a well known problem I've always loved my chevy.

I recently had to replace my transmission (2020 Chevrolet Traverse) due to shuddering from manufacturer's fault in assembly process. Now I'm having to replace the transmission in my mother's 2018 Chevrolet colorado that has less than 65k miles. These issues cause power loss while driving. I was in the middle of passing another vehicle when my vehicle experienced power loss. This is a huge safety issue, not only for my family but many others that I know that are experiencing or have experienced the same issues. I have 3 family members that have had to have the same repairs as well as over 40 acquaintances. I had assumed with the thousands others that I've chatted with on facebook and reddit that this would have been a recall, sadly, gm/Chevrolet doesn't seem to care that it is their fault that their consumers are having to spend thousands of dollars to correct an issue that leaves the manufacturer at fault. With the thounsands experiencing the same issue, I feel that those that have already had to spend money should be reimbursed.

Upon shifting to park, an error message prompts us to "shift to park". The shifter is in park position, however the vehicle says it is not. The chevy dealer recreated the issue and advised to repair because it will lead to not being able to turn off the engine, or not being able to start the engine, or it will drain the battery. Any of the above could lead to a safety issue depending on where the failure could occur. I had the veicle repaired at the expense of $501. 29.

Car will shift into park and dash will say park but it keeps saying shift to park and car will not turn off.

Purchased the vehicle in 2024, the vehicle recently has been notifying “shift to park” when vehicle is on park and ignition is turned off, the notification stays on and alerting, so I am unable to leave the vehicle. I must turn the vehicle on and off again, while moving the shifting lever back and forth from drive to park, this must be done a minimum of four times before it reads the lever in park position. It’s a safety hazard because, the vehicle cannot be left on shift to park and possibly roll away or drive/excel on its own. Vehicle has not been inspected at this time, when purchasing the vehicle in 2024, car fax report did not indicate any issue with power train. Would also like vehicle to be inspected for missing airbags, when driving 65mph or more, you can hear and feel air coming in and out of side front left passenger side of the vehicle.

The shifter control assembly keeps malfunctioning 3 times in the last 4 years on our 2019 chevy Traverse. When my wife puts the shifter in park and proceeds to shut down the vehicle, the Traverse will not recognizes that she is in park already, and will not let her shut off the vehicle. She must then reverse and forward the care several times until the sensor or solenoid engages and recognizes it is in park. This creates a dangerous and frustrating situaiton. The dealership has confirmed this is an ongoing inssue with the Traverse, and chevy customer service also confirmed on the phone that this is a weel known issue and she was not sure why they did not recall or take care of this issue already. Official problem is "internal failure to shifter/solenoid assembly". This has caused issues 3 times and our vehicle is not even at 90k miles. This is not a wear ant tear part, but a core functional item that should not go bad repeatedly in such a short period of time on a newer vehicle. Chevy customer care has encouraged me to file this complaint and get this on record and have the NHTSA begin to work with the manufacturer.

When putting the vehicle in park I have to keep moving the shift handle back and forth to put it in park and the ac keep leaking freon under the dash board a bad smell come into the vehicle make me dizzy.

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.

Shift to park error code where vehicle does not turn off and vehicle does not appear to be in park. Gm vehicles had this issue in the past and still appear to have this same issue.

The contact's husband leases a 2023 Chevrolet Traverse. The contact stated that after the vehicle had been parked for approximately 10 minutes, the contact who was occupying the front passenger's side seat turned off the vehicle while the driver's seat was unoccupied. The contact stated that the vehicle started rolling backwards and crashed into a tree that was 100 ft. Away. The contact husband, who attempted to stop the vehicle from outside, sustained a partial tear of his hamstring and calf muscle on the right leg and received assistance from an orthopedic. The contact sustained a contusion on the left hand but did not seek medical assistance. The contact and her husband were able to drive away from the scene and pulled into a parking lot, where the failure was reproduced. The vehicle was then driven to the residence and parked in the garage. The dealer was notified of the failure and referred the contact to the manufacturer for assistance. The contact stated that the manufacturer was notified of the failure and sent a field investigator, who inspected the vehicle but failed to inspect the transmission. The manufacturer later informed the contact that no assistance would be provided. The contact was not provided information on the field inspector assessment. The contact related the failure to NHTSA campaign number: 23v172000(power train); however, the VIN was not included in the recall. The vehicle was not repaired. The failure mileage was approximately 14,000.

When placing the Traverse in park the car will not shut off and warns that the car is not in park while other indicators show that it actually is in park. Confusing and worried that it is not in park and that the car con not be safely shut off. Flipping the shift knob and button numerous times has, so far, finally allowed the car to shut off safely.

The vehicle would not shift into park. We were told by the dealer park switch sticking at times.

Transmission continually failing. Judders under acceleration. Metal in transmission fluid and leak in transmission.

When I stopped and ready to park the car, I put transmission to 'p' park position and press button to stop the engine. Even it is in park (p) position, the display shows 'shift to p position' message. I have to restart the engine and change the transmission and put it again 'p' position. Sometimes I had to try few times. I searched the internet and this looks like a common problem, but no recalls on this model.

Regarding the vehicle's functionality, the horn activated unexpectedly on or around may 2, 2025, sounding continuously for approximately 10-15 minutes while the vehicle was occupied.
