In owners' own words
Not sure the exact cause yet. But another big leak of coolant from the car. This is the 4th big problem with the same issue. I have been dealing with engine/radiator/coolant problems with this car since April 2024. It has been in the shop 2 separate times for 9 weeks total. With other visits in between. There is something wrong with this car. Engine
The engine stopped working. I was stranded on the highway and needed a tow. It was towed to a Chevrolet dealership in Alexandria MN, where it was diagnosed with a spun rear main bearing in the engine needed to be replaced. There were no warning lamps or anything prior to the engine completely shutting off and not being able to start again. Engine

First time was at 41k miles fixed by dealer under warranty, it happened again today 05/02/2025 with 100k miles on the engine with ticking and cranking noises and being told it need an new engine. 5.3L suvs need to be investigated and be recalled for engine failure it is a common issue please help.
