This is long and I'm sorry**
I purchased a 2011 Chevrolet Camaro on April 30, 2016 from Surburban Chevrolet. At the time of purchase it had 22,395 miles on it. On January 23, 2020 the motor blew with 49,033 miles on it. I changed the oil every 3,000 miles with Mobil 1 synthetic. This had been A GREAT car until now. I have contacted the dealership and was told the warranty is up as it was 5 years or 100,000 miles. Which I knew this. I spoke with Nick Chelsea and he helped me as much as he could but his hands were tied from a dealership standpoint. Which I appreciated the help. So to GM I go. I called 800-222-1020 and FINALLY got to speak to someone. Explained what happen and all he could say to me is I should of purchased the extended warranty. He said your vehicle had a 5 year 100,000 mile warranty. I said I'm sorry I didn't drive it more to blow up before the warranty was up. He then referred me to the dealership I purchased my car from. I told him I have spoke with Nick Chelsea. I also told him I have been doing my research online and GM forums all full of my same situation. V6 engines going out at 40,000 from the bearings. He told me he knew nothing if this. I explain forums people are getting engines replaced and so far with the new engines and upgraded bearings no reported problems. GM is aware of this problem as they are upgrading the bearings in the engines they are replacing. He once again said I should of purchased the extended warranty. I said GM needs to stand behind their motors. I put 27,000 miles on it in 4 years. I said so are you telling me there is nothing you can do for me? He said have the car towed to the dealership I purchased it from and have them do a diagnosis. I told him I already inquired about that with Nick and it would be roughly $1300.00. I said GM should be doing that. He said that there is nothing GM will do for me and he hoped I had a good day.
I am hoping someone can help me with this. I'm no way shape or form should my engine of failed. GM is aware and they need to be held accountable.

Wow, sorry to hear about this!

I've heard of a couple of these, but they've barely ever popped up here.

From my perspective you've done as much as I know to do . . . and unfortunately GM has done as much as they've promised to do. I know that hurts, but I'm a victim of the 6T70 35R wave plate problem, just mine was ~22,000 miles after the "we finally acknowledged this problem after many folks were threatened with financial ruin over it" extended warranty was up.

What are the symptoms of this engine "blowing up"?

What was it doing when this happened?

Do you know anything of this car'* history prior to your ownership?

I'm surprised they didn't even offer any type of goodwill. I work at a Volvo/Mack dealer and we goodwill work all the time. This is a bad reflection on GM.

Normal for GM from my experience, even when a dealer is completely in the wrong.
