2018 Chevrolet Traverse

The contact owns a 2018 Chevrolet Traverse. The contact stated that while attempting to park the vehicle, the gear shift selector was shifted to park(P), and the message "Shift to Park" was displayed, and the contact was unable to turn off the vehicle. The contact stated that after shifting to park several times, the failure self-corrected. The contact stated that the failure was intermittent. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The contact indicated that the vehicle had previously been repaired for the same failure. No further information was available. The failure mileage was 84,000.

The vehicle has a design flaw which causes a bracket which connects the 2 pipes which connect to the catalytic converter to fail. Once the bracket has failed, the rear catalytic converter is allowed to vibrate more than designed, adding extra stress to the catalytic converter. Over time, this additional stress causes the catalytic converter to fail, releasing harmful gases directly from the engine exhaust manifold with carbon monoxide and other harmful gases into the air and into the passenger compartment of the vehicle. This is a know issue that GM has recalled on the 2019 (recall N212356540) and 2021 (recall N222385510) model year Traverse. Other years may have also been recalled that I am not aware of. For some reason, GM has neglected to take ownership of this issue on the 2018 Traverse which shares the same design as both the 2019 and 2021 model years. I have gone to the dealership and contact Chevrolet's customer service multiple times and they refuse to reimburse me for the cost of the necessary repairs. I have already purchased the broken and necessary, ancillary components and repaired the vehicle myself because I did not want to pay the dealership over $2000 in labor which they quoted me.

The vehicle was taken to the local mechanic, who informed the contact that the exhaust manifold bracket had failed and needed to be replaced along with a section of the exhaust system. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure and informed that the vehicle was not covered under the manufacturer's extended coverage related to the failure.

Been receiving a "shift to park" warning message since last year. It seems to be a known issue, however nothing has been done about it. I've had trouble from time to time getting the car to recognize the Park position I've put the shifter in and occasionally have sat in my car with it on for minutes attempting what I can think of to have to car finally recognize that I shifted into Park. I had called a Chevy dealership near me who advised because my car is outside warranty it would not be a covered repair. I'm concerned as I have 2 young children and this is our family vehicle. I cannot leave a car running while I have my children inside or with them inside and me outside trying to turn the car off.

My 2018 Traverse has had the “shift to park” message displayed on the instrument cluster when I put the vehicle in park. Even though the red P for park is illuminated and the vehicle is clearly in park the ignition will not power off when you depressed the start/stop button. The vehicle displays the message shift to park. Now this has transpired for about 3 months and it is very frustrating when you can not park in your garage especially when storms are imminent from the forecast not to mention carbon monoxide poisoning! Now I or my wife have to continuously push on the shifter to get it to turn off. Or we have to turn the vehicle back on and try driving around the block or wherever we are at. Now not being able to turn your engine off is a definite safety concern especially when you have children and pets . This has been happening in GM SUV’s and is a known issue by GM but they seem it’s not a safety issue due it not causing any issues while driving. I had the vehicle repaired at our local dealer and it was $789 to repair the malfunctioning item. I have never heard of a shifter being defective in today’s modern cars. Whether it’s a mechanical issue or electrical issue it needs to be addressed. If I were to live an apartment dwelling with indoor parking I would have to find some other means to park if I could not turn my engine off. I have read numerous complaints online via forums which is very saddening when these automakers claim dependability with their very expensive vehicles. If the vehicle was built with defective or faulty components how does thst burden fall on the consumer?

To the National Highway Traffic Safety Administration (NHTSA), I am writing to inquire about an issue recently encountered with my 2018 Chevrolet Traverse. On July 21, 2025, my vehicle was at Riverview Chevy for its state inspection, during which the rear toe links were identified as failed and required replacement. This service, including the necessary alignment, resulted in an out-of-pocket expense of approximately $750. I recall previous discussions regarding a potential recall concerning failing rear toe links on 2018-2020 Chevrolet Traverse models. While my vehicle is a 2018 model and experienced this exact issue, the dealership indicated that no recall was pending for my specific VIN. I find this discrepancy concerning, particularly given the known history of this component in similarly years and the fact that my vehicle indeed suffered this failure. I will be submitting the relevant documentation from the dealership outlining the repairs performed. I kindly request that you review this matter and provide clarification regarding the recall status for my vehicle's VIN. I am seeking a resolution regarding the costs incurred for this repair, as it appears to be a known issue for which a recall may have been appropriate. Thank you for your time and attention to this matter. I look forward to your prompt response.
