I keep having emission problems. The first time I took it to the dealership they fixed then it messed up again had that fixed about three months later check engine light was on again same thing had it fixed for the third time check engine light went off and of course came back home had to fix it again it’s off for now. I’m just waiting for it to pop back on. Second problem that I’ve been having is the fuel pressure sensor changed it light went off now it’s back on. They say change the fuel pump just to see. Did that check engine light back on? When is the check engine light gonna go off another problem that I’ve been having shift to park that pops up every so often at this point, I do not recommend Chevy traverses too many problems and nobody fixing them

I have been experiencing an intermittent issue where the vehicle displays a “Shift to Park” message, even though the gear shift lever is clearly in the Park position. When this happens, the vehicle will not fully shut off, and I have to repeatedly move the shifter back and forth or restart the vehicle to clear the message. This issue began around January 2024, and it has become more frequent over time. I understand that this is a known defect in GM vehicles, and that GM issued Technical Service Bulletin #19-NA-206 to address it. According to the TSB and owner reports, this problem is caused by a faulty park switch or microswitch inside the shifter assembly, and the solution involves installing a jumper harness and/or replacing the shift control assembly. This is both a functional and safety concern, as the vehicle may not recognize it's in Park and could potentially result in a failure to turn off or secure properly. I’m requesting that General Motors or an authorized dealer perform the recommended repair per TSB #19-NA-206 at no cost, as this is a widely reported manufacturing defect. Please advise how this issue can be resolved as soon as possible. I am attempting at uploading a photo and a video. The system does not allow videos and it is rejecting the photo.

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 the federal safety agency 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 the federal safety agency 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)

Torque converter is bad. Codes will not come up when test ran. Mechanics mis diagnose the issue until it’s too late. Mechanic now doesn’t think it’s worth it to replace- wants whole new transmission.

One year ago the check engine light came on. Diagnosis stated EVAP system leak. Replaced a bad purge valve.now almost a year later the engine light comes back on car also started struggling shifting and shift to park would come on when car was already in park. Diagnosis states a large leak in EVAP system, smoke test determined leak was coming from the fuel canister. Canister was replaced and within two trips engine light came back on and car continues to struggle shifting as well as having a rough idle. Another diagnostic test reported bad fuel sensor. 2019 traverse seems to have a lot of EVAP system issues and have been told as well as read that this is a trending issue with this vehicle. With each diagnosis report it states it would fail fuel omission.
