2018 Chevrolet Traverse

My engine light came on, so I took it the mechanic. According to the reading it says it was my purge valve, they replaced. After driving 30 miles it came back on. I took it back and they thought it was a defected part so they replaced it again. After 30 miles, it came back on. The mechanic searched online and showed me this issue was for 2019 for a recall. I contacted GM to see if there is a recall for 2018. They said no. At this time the engine lights stays on, but it gives a evap engine light. I can't pass smog due to the issue. The gas tank does not have a cap, it's open. This is how it was when I purchased the vehicle.

The contact owns a 2018 Chevrolet Traverse. The contact stated that upon parking and attempting to turn off the vehicle, the message "Shift to Park" was displayed while the gear shifter was already in park(P). The contact stated that the vehicle responded after several attempts to shift to park(P). The dealer and the manufacturer were not contacted. The vehicle was not diagnosed or repaired. The failure mileage was approximately 81,000.

When car is shifted into park, it does not register that. It is in park. Therefore the car keeps beeping, and you cannot leave the car in this position. This is the second time that we have had to address this problem once in 2021 and now in 2026 I believe that General motors should fix this problem without the consumer being charged to have it corrected.

The exhaust system on my 2018 Chevrolet Traverse has failed due to cracking in the exhaust pipe and/or muffler assembly. This appears to be consistent with known issues in similar model years where exhaust pipe brackets separate and cause cracks or holes in the exhaust system. The failure has resulted in excessive exhaust noise and potential exhaust leakage. The dealership has confirmed the issue and recommended repairs costing several thousand dollars but stated my VIN is not included in the existing recall or special coverage. Yes, the vehicle and failed components are available for inspection upon request. The failure of the exhaust system creates a risk of exhaust gases, including carbon monoxide, entering the passenger cabin, which poses a serious health hazard. Additionally, a compromised exhaust system can affect vehicle performance and emissions, and in some cases may increase the risk of fire if hot exhaust gases escape in unintended areas. This issue is especially concerning because it has been identified in other model years of the same vehicle, yet my vehicle is not currently covered, despite experiencing the same failure. This creates an ongoing safety concern for myself, my passengers, and others on the road. The problem been reproduced and confirmed by a certified Chevy dealer.

Vehicle was driving fine in good condition and well maintenance. No warning at all and went to drive it home from a friends and it would not go in reverse at all. Towed to dealership and they said it’s a transmission issue. There is a recall on 2018 chevy traverse vehicles. My vehicle is not showing up but I do believe this could be the issue and should be considered a recall
