Yes I’m dumb enough to ask this question and yes I waited for Reddit to tell me what to do before trying it myself

Had it for about 7 months. No issues. LOVE IT!

I have a 2021 Chevrolet ACTIV trailblazer. Bought it new. About a month ago my check engine light comes on. Car is driving normally. I stop by an auto zone and they pull my codes for me. There are a lot, maybe a dozen. I make an appointment at the Chevy dealership closest to me for the next day.

That evening I needed to move my car out of the driveway for garbage pickup, noticed the check engine light is off. Okay, weird, still taking it into the dealership. Next morning get into my car, check engine light comes on and also low power mode warning comes on. I turn the car off, crank it again and the check engine light goes off and no low power mode warning. Okay, dealership is two miles away. I drive it there. It drives normally.

Fast forward four days later, they can find nothing wrong but they tell me I need a new battery. I thought that was weird, my battery was like only a year and a half old. (I had to replace battery and alternator at around 60,000 miles). So, I leave dealership with new battery and a new set of back brake pads I had been talked into, and the check engine light off. $1200.

Next day check engine light is back on. I immediately drive it back to dealership. They keep it for seven days trying to find the problem. Come back finally and tell me they suspect rodent damage in the wiring harness and it will be a four hour $800 diagnostic fee just to try to find the problem, with no guarantee they will. I decline not only because of the $800 fee, but at this point I have decided this dealership is shady af and I’m taking my car somewhere else.

Do some research and find an independent garage with amazing reviews about people with electrical problems and I take it there. The owner of the shop comes out, and I give him the printout of my codes the dealership had pulled. He decides none of these codes relate to one another and he thinks I have water damage from my sunroof drain being clogged, and it’s damaged modules somewhere under my floor in the car, probably under the drivers seat. So I let him do his thing, and he takes the interior carpet and seats out of my car to see if there is water damage.

Fast forward two weeks later, he says he has found light water damage but cannot find the source of the leak. His last message said that they are putting the interior of the car back together and I can pick it back up, apologizing that they couldn’t find what was wrong with it.

So, I will be going to pick up my car, probably with the check engine light still on and me still nervous as hell to drive it more than a few miles at a time back and forth to work. Rideshare has been killing my wallet since this has happened and I’ve put out what is serious money for me now and the car still has some sort of issue. It has about 88,000 miles and of course I just paid my car off this year. Besides the alternator issue that happened a while ago, the car has run great.

Im a single gal and money is tight. I’d really like to not have another car payment. I’m looking for advice of any kind from anyone that may have an idea of what I should do or where I should go. I don’t want to take it back to the original dealership if possible because per online reviews, they’ve got some shady practices in their sales and service dept also.

I’ve uploaded a pic of the codes in case anyone can decipher what may be going on. I really appreciate anyone’s guidance or help that may have experience with this. Thanks Reddit!
