Got a ‘21 Tahoe with 20k miles on it and just recently started to notice this “Check System” message appearing on the Air Filter Life screen instead of the usual percentage.
Curious if this means the air filter life is gone or if the sensor is bad. So far I have never replaced the air filter...
Got a ‘21 Tahoe with 17k miles on it which I’ve had since it was new in April 2021 so it’s about 2 years old. It sits in a garage most of the time except when I’m at work.
I’ve noticed both headlights have a fog inside each of the lenses that looks like they’d be 5-8 years old. Anyone else’s...
Anyone else have an issue in their 2021 model with the fit and finish of the front bumper piece where it meets up with the fender and front headlight?
Attached are photos if what mines doing. I had the dealership fix this once where they removed the bumper and repainted it as there was a...
Any idea on what this noise is? When I stop or let it idle through a drive-thru for example, then come to a stop, about a second after that I'll hear this weird metallic/squeaking type of noise that lasts another second or two. This is easily repeatable by letting it go forward a little more...
I was just curious if anyone has regularly put E15 gas in their gas tank and what their experience was? I know the manual says it's fine up to E15 or 15% Ethonol. I've got the 5.3L engine which doesn't require premium gas.
I live in Iowa and the E10 (87 octane) is discounted as an incentive...
Here’s something strange. Twice now on days when the high temp was 0 degrees or less here in Iowa, when I go to remote start my ‘21 Tahoe and later get inside it the dash will display the message “Heater Performance Mode Active”. Anybody know what that means? I can’t find anything in the...
Saw this recent post on GM Authoroty where lifter issues are present in new 21’s that are arriving at dealers.
It sounds like the dealer will need to replace the bad components before the customer takes delivery...
Just a PSA that this was recently posted on the GM TechLink website where it talks about chafing on one of the engine wire harnesses which can cause a variety of problem codes to be set.

Looks like it can affect all engines in some of the 2021 Tahoe, Yukon, and...
This might just be coincidental, but thought I'd mention something about it...
I took my 2021 Tahoe Premiere w/5.3L V8 (built in March '21) to the dealer for an alignment under warranty (since the steering wheel has been off a little since it was new) which they covered under warranty. While...
So, I got my new 2021 Tahoe Premiere about 2.5 weeks ago and took it on it's first road trip down to a friend's place about 60 miles away and when we were driving around that city, we parked somewhere and I could hear air coming out of one of my 22" tires.
We were next to Sam's Club so asked...
