2024 Chevrolet Traverse engine problems

“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 NHTSA to investigate the quick-connect coolant fittings across the entire LK0…”

“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…”

“The contact owns a 2024 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the vehicle stalled with the engine warning light illuminated. The failure was a recurring failure. The vehicle was towed to a dealer and was diagnosed with engine failure. The vehicle was repaired, but the failure persisted. The manufacturer was made aware of the failure. The failure mileage was approximately 75.”

“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.”
