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 experienced complete brake failure while coming up to an intersection during rush hour. To avoid crashing into the vehicles in front of me I went off the road onto the shoulder and coasted until I stopped. During this “brake failure” popped up on my dash. (I have a picture) I ended up turning the car off and then starting it back up. Everything appeared to be fine, however I was not fine. I called the dealership right away and brought in. They diagnosed it as needing brake master cylinder and it took about 30 days for the vehicle to get fixed. Now I’m experiencing transmission fluid leaking. The vehicle shudders when accelerating.

My 2024 Chevy Traverse is leaking coolant within the radiator hose system. While driving on a busy interstate, the vehicle went into protective limp mode reducing acceleration, creating a dangerous situation for myself to manage. A check engine light did come on with the reduced acceleration notice. I am having to add coolant to the vehicle constantly to drive it. Parts on our national back order now due to the huge influx of others experiencing similar issues. Dealership has confirmed leak - however I’m told it is not covered until manufacturer warranty and can be costly to repair!

I had my upper radiator hose leaking coolant after only owning this brand new vehicle about a year and half. Has less then 20,000 miles on it. I was able to get it into a Chevy dealer and they confirmed the leak. Seems the original part was defective. Was told I could take it home and drive it until the part came in(no eta on that) but to monitor the levels of coolant. Within two days I had a huge puddle of coolant in my driveway and had to bring it back to the dealer immediately. Thankfully I had coolant on hand and was able to refill the reservoir to make it to the dealer. This is a big concern because this is my wife’s car that she uses primarily to transport our two young children around. Thankfully she didn’t get stranded somewhere.

2024 Chevy Traverse transmission failed at 5,200 miles while exiting a major interstate. Vehicle struggled to downshift and switch gears. Transmission fluid leaked excessively while driving and parked. The vehicle was not drivable after failure. Unreliable and clunky acceleration and slowing down put passengers, including children - especially those in the rear-most seat - in danger. The problem was confirmed by the dealer. No further inspection outside of the dealership has occurred. There were no warnings prior to the failure or even during the failure. It wasn't until 20 minutes after the first observation of unusual handling, when an attempt to put the vehicle in reverse was made, that the notification was on the dashboard. When starting the vehicle 18 hours later to take a photo of the exact mileage, no alert was on the dash at all.

We were driving on a street and the vehicle suddenly just stopped. We could not get it out of park. We could not get into neutral it would not shift into any gear and it said transmission needs service. That is such a dangerous thing because luckily it wasn’t a busy street because it just stopped in the middle of the street and we waited there for an hour and a half to get a truck to tow it off
