2013 verono
My 2013 Verono jumped time bent 2 valve rods and did alot of damage! Buick will do NOTHING this vehicle has less than 100,000 miles on it!!! After some research I have learned that this is an issue with the Ecotech engine. The timing chain guide is PLASTIC!!! so please if you own this vehicle save yourself a ton of money and have your mechanic check this from time to time. There are no recalls for this Buick seems to think it's ok to put plastic in hot oil and have a metal chain constantly causing friction on it.
Once everything was fixed and sensors replaced now the vehicle is stalling and one else have this problem?

Sorry to hear you had these problems and GM will not offer any assistance.

Plastic timing chain guides/dampers are fairly common. Sounds like your chain may have stretch a bit and ultimately is the root cause. Just curious, is this a 2.4L or 2.0L motor?
