Engine started consuming oil at around 25-30k miles. Now adding 3Q between the recommened oil change period. First realized this when driving on road trip and the engine oil low warning triggered. Driving at night on a interstate - had to pull off and find a safe place to check it. Could of been stranded with an engine failure in the middle of nowhere. Dealer confirms the issue, but GM says 1Q per 2000mi is "normal" in their world. Refuses to do anything when losing 1/2 your oil every oil change internal...

I own a 2023 Chevrolet Traverse RS, VIN [XXX]. This vehicle has repeated safety-related failures involving the engine/cooling system, fuel-injector/misfire system, steering-assist warning system, and electronic parking brake system. The vehicle is currently at AutoNation Chevrolet West Austin, dropped off on XXX, and is available for inspection. Soon after delivery, the vehicle began losing coolant and overheating. This was not isolated. Before the engine was finally replaced, there were at least four documented coolant/overheating-related dealer visits or repair notes: XXX. The problem repeated again on XXX, becoming the fifth coolant/overheating-related visit and resulting in GM/dealer-authorized engine replacement after internal coolant-related findings. Dealer records show low/empty coolant reservoir, overheating, fan-running symptoms, almost one gallon of coolant added, no external leak found, coolant dye added, GM TAC involvement, and internal coolant findings. After engine replacement, the vehicle continued to fail. In February 2026, it displayed check-engine light and “Steering Assist Reduced / Power Steering Reduced.” The dealer confirmed misfire and replaced cylinder 1 fuel injector. In April/May 2026, the vehicle displayed a service parking brake warning; the dealer documented left rear parking brake actuator high current. Now, on XXX, the vehicle is again at the dealer for blinking check-engine light, and the dealer advised the code shows another engine misfire. My family’s safety is at risk. Repeated overheating, engine replacement, steering-assist warning, parking brake warning, and recurring misfire create unsafe drivability risk, especially on highways, merging, intersections, or long trips. I no longer feel safe operating this vehicle INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I am filing this complaint due to a recurring exhaust leak in the front exhaust pipe of my 2023 Chevrolet Traverse, which poses a potential safety hazard. During the vehicle’s bumper-to-bumper warranty period, Freedom Chevrolet in San Antonio replaced a leaking front exhaust pipe (receipt attached), a known issue covered by a Technical Service Bulletin (TSB) for earlier model years (2018–2022) but not for the 2023 Traverse. Less than two years later, with the vehicle now at approximately 84,000 miles, the front exhaust pipe has failed again, exhibiting the same leak issue. This recurring defect is concerning because exhaust leaks can allow carbon monoxide and other harmful gases to enter the vehicle cabin, posing a risk of poisoning or impaired driver awareness, especially during extended operation. Additionally, the issue may contribute to environmental hazards due to improper emissions control. Despite my requests for assistance from Freedom Chevrolet and GM Customer Care, I have not received a satisfactory resolution, and the repair cost falls on me as the vehicle is out of warranty. I am aware of complaints and TSBs documenting similar exhaust leak issues in Chevrolet Traverse models from 2018–2022, including a recall for the 2019 model year (the federal safety agency ID: N222385510), suggesting a systemic issue that may extend to the 2023 model. The lack of a TSB or recall for the 2023 Traverse leaves owners like myself vulnerable to repeated failures and safety risks.
