2024 Chevrolet Traverse engine problems

Filed Oct 23, 2026 · Engine · PA

I have a 2024 Chevy Traverse with 32,000 miles. It has been using a quart of oil every 4,000. Bulletin states less than 1 quart every 2,000 miles is okay. Unbelievable that a new car is allowed to use any oil. Did not know I purchased a two‑stroke engine. If someone does not check their oil they could be running 2 quarts or more low in between oil changes, which could damage the engine. Just checked my level, see photo. Drove 3,000 miles and the level was almost at the bottom of acceptable. I still have 60% oil life before the next change. After another 1,000 miles probably would have gone below the low line. Not good for the engine. Mentioned to the dealer during the first oil change and they started overfilling. Told them to stop that as that is not good for the engine. I am worried the engine will fail prematurely.

2024 Chevrolet Traverse, 2.5L turbo (LK0). The cooling system has repeatedly lost coolant through quick-connect hose fittings. On 4-3-2026, at 36,650 miles, Washington Chevrolet replaced the radiator inlet hose under warranty for coolant loss. After that repair the vehicle kept losing coolant, and I have had to top off the reservoir repeatedly. No low coolant warning or dash alert has ever appeared. On 10-14-2026, at 49,066 miles, the same dealer found the outlet hose at the coolant surge tank leaking, rated it Critical, and quoted $480.30 to replace it. The dealer declined warranty and goodwill coverage. Safety concern: coolant loss with no driver warning can lead to overheating, reduced power, or engine shutdown while driving, including at highway speed. GM has acknowledged quick-connect coolant leaks on this vehicle under Special Coverage N262546590 (radiator inlet hose, 2024-2026 Traverse) and bulletin PIT6494A (the same seal failure on GM's 2.7L turbo trucks). My second leak is at a different quick-connect in the same cooling system, which those programs do not cover. I am asking the federal safety agency to investigate the quick-connect coolant fittings across the entire LK0 cooling system, not just the radiator inlet.

I am reporting a serious safety incident involving my 2024 Chevrolet Traverse RS AWD, with approximately 34,378 miles. On or about [XXX], while the vehicle was being driven near Sarasota Florida at approximately 25 mph, it suddenly lost propulsion and all electrical power. The instrument panel, displays and vehicle electrical systems went completely dark. The vehicle was completely dead and would not restart. Police subsequently jump-started it, but the vehicle’s systems did not initially operate normally. This vehicle previously experienced another complete electrical-power failure while parked overnight, and the dealership has a record of that incident. Following the in-motion shutdown, the dealership performed a complete software flash using USB and stated that a software problem may have caused a parasitic battery draw. I understand how a parasitic draw could discharge the battery while the vehicle is parked. However, I have not received an adequate explanation of why the vehicle lost all electrical power while the engine was running and the charging system should have been supplying power. I am requesting that General Motors open a formal product-safety case, review the dealership’s diagnostic and programming records, determine the complete cause of the in-motion shutdown, and provide written confirmation of the tests and repairs performed. Please provide me with the GM case number and escalate the matter for appropriate technical or field review.

Vehicle overheated while driving on interstate in 32F weather. No warnings lights warning of low coolant - only noticed climbing temperature gauge and cooling fans running at full speed. Pulled over and drove slowly to nearest exit with service station. Found coolant reservoir completely empty but with no obvious leaks. Chevrolet dealer diagnosed leaking radiator hose - typical with numerous social media report of similar issue with the 2024 model year Chev Traverse Generation 3.

The car has a check engine light. Code reads P3075. The app shows an Engine Cooling System error. Please schedule service now. The dealer diagnosed the issue: the coolant pipe to the radiator has failed and needs to be replaced. The part is on backorder, and there is no ETA for the repair.

This has happened two times. Driving down the road between 35-55mph. "Speed limited drive with care" no CEL. Took to dealer, advised with a CEL or no codes nothing they could do for it. Multiple nights I get home and the fan stays running after engine shutdown. Engine overheat within 10 min of drive time. OIL SMELLS LIKE FUEL. This time engine throttles back and nearly caused accident with not being able to merge.

I am filing this complaint regarding a persistent and unresolved defect with my 2024 Chevrolet Traverse, VIN: [XXX] . The first occurrence of this issue was in June 2025. Since then, the vehicle has repeatedly experienced a “Check Engine” warning, engine misfires (cylinder misfire), loss of power while driving, and severe engine shaking. These symptoms make the vehicle unsafe to operate. The vehicle has been taken to an authorized Chevrolet dealership approximately 20 times for the same ongoing issue. Despite multiple repair attempts, the problem has never been permanently resolved. In total, the vehicle has spent about three months out of service at the dealership. As of January 14, 2026, after the vehicle has been at the dealership for over two weeks, I was informed that the dealer is unable to repair the vehicle. They have escalated the case to the manufacturer, General Motors, because they cannot identify a permanent solution. The current mileage of the vehicle is approximately 41,700 miles. This ongoing defect makes the vehicle unreliable and unsafe for normal use. The repeated failures to repair suggest a potential manufacturing or design defect rather than an isolated incident. I respectfully request that the federal safety agency review this matter and determine whether an investigation or further action is warranted.

My car is leaking coolant. There is no warning light or anything. Had to be towed to the dealership. Dealership confirms the truck is not driveable and needs an upper radiator hose which is on backorder until January. There aren't any loaner vehicles according to the dealership.

To date, I have brought the vehicle to the service department four times, primarily due to the check engine light and other critical malfunctions. Below is a summary of the incidents: First Visit (approx July 2024): The vehicle suddenly lost acceleration while I was in traffic, leaving me stranded in the roadway. This posed a serious safety risk. The vehicle remained in the shop for 28 days. Second Visit (September 29, 2024): Multiple warning lights illuminated, and several diagnostic codes were detected. Third visit (do not recall the issue): Will find work orders if needed Most Recent Visit (December 3, 2025): A coolant leak caused the temperature gauge to spike, resulting in the air conditioning shutting off due to overheating. The next day the check engine light came on. I had no warning prior to the guage spiking. In addition to these major issues, the following concerns remain unresolved: Brakes continue to squeal. The dealership advised this is normal and that front brakes wear faster. Reverse sensor activates randomly, causing the brakes to engage abruptly. Also the front crash sensor triggers without any obstruction ahead. The dealership recommended disabling this safety feature. These recurring problems raise serious safety concerns and significantly impact the reliability of the vehicle. The advice to disable safety features is unacceptable and does not address the underlying issues.
