Let me share my experience on this.
It really started acting up and finally became unusable.
Car overheating got worse, in two miles to drive home Thursday night, I had to stop 4 times to let the engine cool down.
So, I went to take it in the next morning and same issue. Had to stop every 1/4 mile or so to cool down from 250 (light coming on). After about 5 times doing that, I was 1 block from the dealership (less than 2 miles from my house) and it wouldn't start at all.
So then I had to call a tow truck and have it towed the last block to the GMPP dealership I always go to.
They fixed it at no charge and paid for the tow along with checking complete system over and sent me on my merry way. I was stressing major on this.
It was there for two days but it's fixed now - for good I hope. Drove it tonight for 1 1/2 hours with no issues. Temp hovering at 194-199 most times. Stop and go it went to 205, but then right back down to 198 when started moving.
So, I got the issue fixed under warranty and it was marked that way on the paperwork from the dealership.
I don't know if this is typical, but just thought I'd share my experience in Charlotte, NC.
Maybe was nicer because we take both our cars there and the company I work for has a fleet account with them. But in any case I'm not complaining.
