2020 HTC with 5K plus miles. 25 mile, 40 minute ride, top down, AC on, medium humidity. Parked in garage and 4 hours later this puddle is observed. Also a few small moisture patches down the centerline of the car. Feels like water, no smell, I even tasted it…..a tad salty.
Never saw this amount at this location before.
Opinions and ideas welcome.
Or possibly condensation from a weep hole in the exhaust.

[QUOTE=RKCRLR;1605310640]My opinion: AC condensation. The evaporator condensation drains into the center tunnel and the water finds the easiest path out.
I agree, most likely AC condensation that had pooled in the center tunnel. Nice to know that you don’t have one of the cars that had the moisture drain into the passenger foot well.

sleekvt, that's a lot. I'm truly very sorry about the problems you're experiencing with your new C8. I can't even imagine how painful that experience must be. I hope it is resolved completely and quickly. For the record, my C8 has not given me any mechanical problems whatsoever over 10 months and 6400 miles of delightful service.
You mentioned that your dealership told you that the extended warranty they offered was only available at the time of purpose. My dealer held me up for about half an hour during delivery trying to sell me such a warranty which is not a GMEPP. It looked good, but the pressure to sell it gave me the gut feeling they were trying to sell me a "bill of goods." I declined, of course. As I and others have posted, the GMEPP can be purchased up until the manufacturers 3-year warranty ends. You might consider canceling the warranty they sold you.

It's probably best to call Dennis Fitchner and give him a description of your vehicle, its delivery date and current mileage. He'll email a very extensive list of months-mileage choices and the price for each tailored for you car. In May 2018, his prices were several hundred dollars better than others I found on the Internet.
.Probably alot of C8 buyers lease so they don't have to worry about this to a certain extent.

The problem with these warranties are they are usually a BAND AID FIX. It's no good if you plan to keep your car for a very long time or over the warranty period because eventually that warranty will expire plus dealerships will use the very same part only to fail again in the future unless they actually correct the problem with upgraded part. Otherwise same old problem will happen again and this time it will come out of YOUR pocket $$$$.

I took my C8 into my Chevy dealer for my first oil change. The dealer said that my coolant plug/ cylinder head is leaking. The y said not to drive the car for any length of time and wait until the part comes in to get it fixed. Has anybody else had this problem? Or if anybody can clue me in on this I would appreciate it.

2021 10k miles my A/C compressor took a crap.
The clutch seized open causing a horrible loud rattle I thought my engine was toast when it first happened lol. Busted clutch rattle bounces off firewall and redirects intensified sound to the intake manifold area. Obviously no CEL and blowing hot air gave it away, but damn the sound was deceiving.
my local dealer actually had another C8 for same A/C Compressor failure issue and had to order 2… Part on back order of course but only took 2.5 weeks to get them in. Replaced with new unit in like 1/2 day all good now.
Never had an A/C compressor fail on a new low mileage car, but after first thinking I snapped/dropped a spring or some other known horrible top end issue… I’ll take a crapped compressor all day long over that. I don’t know how in the hell they replaced without dropping the engine as its so damn tight in corner against firewall but damn glad they didn’t have to.
