So I took the car to an auto shop. They told me the motor locked up / Seized. The engine has oil. What would cause an engine seize?

Only thing I can think of is maybe a rod or piston? But I would find that odd because I shouldn't be anywhere near that range for that to be an issue?

Any advice, suggestions on how to best approach the issue?

Kinda a shot in the dark, most common would be a failed oil pump. What was it doing before kicking the bucket?

A 2020, hum.


Let me call the dealer I sold mine too, and see what caused it. Might not be the same but maybe a starting point t

I was playing around with another camaro. I did 2 or 3 60mph pulls, so it always had a hard shift at that point. I rolled into my subdivision and the rpms went to zero. When trying to start again just a single click.

To clarify, the mechanic used the term "Engine Lock" rather than "seizure" He said he tried to turn it but wasn't able to.

Doing more research, there is a thread on here, that talks about spun bearings. Another source I found talks about valves getting thrown into the engine which can cause a lock up. Other research says maybe a broken timing belt. I don't know to be honest. I'm the farthest thing from a Mechanic.

I am not sure it is applicable. I see this being the worse possible scenario, and I'm just trying to find out just how bad the situation is.

A bunch of 2020’s were shipped with a bad batch of valve springs. Typically the failure would occur in under 1000 miles but I’m sure some could have went longer. Yours could have shipped with a bad batch of valve springs which would have a caused a valve to drop.

I think 2020 was the notorious year for valve throwing with the LT motors, but I wanna say that was within the first few thousand miles.

Really bummed out by this. I'm not sure what to tell the shop, or if I should just tow the car back to my house until I can figure out what to do.

Going to be hard to determine without further troubleshooting. I would pull the plugs and look for damage on them. Might narrow it down to a cylinder if parts were bouncing around in a cylinder due to valve train issues. If it is due to a spun bearing that locked up the rotating assembly, will probably need to pull the oil pan to confirm.

It's a 2020 do you not have a drive train warranty on it still?

From what work he has listed, warranty is bye bye

And insurance won't cover something like this.

This. No way that car has any factory warranty. It sucks but you're just gonna have to have them tear into it to see if it can be rebuilt or if you need a new engine.

Gotcha...! I didn't look at Fluke's signature. Bummer...! it sounds very expensive. Best of luck with it though.
