Am I asking for too much?

So my 2025 Acadia AT4 (bought brand new) had an upper radiator hose at 19k miles and we took it in for repair in January. We were told the part was on federal back-order but the car was safe to drive. We were sent home with the car and told to fill it with coolant as needed. The car started going into limp mode occasionally and so we took it back in again. They said the limp mode was caused by the upper radiator hose throwing codes and telling the computer it’s unsafe to drive. Then the wifi/onstar goes out so we take the car in a second time. This time they keep the vehicle for 29 days for safety reasons. We filed a complaint with GM and they offered us either a A) extended warranty (which I already purchased 🙄) or B) up to $5k voucher to use towards a new GM vehicle. It just feels like a slap in the face, especially considering they probably should’ve kept the car the first time, but instead told me to go home and maintain it with my own money. Also considering that we bought the car new, $5k wouldn’t even cover the depreciation value that we’ve already lost in the car after owning it for a year and it now having 33k miles on it. We asked for a repurchase or even a trade but they declined that.

Should I just give GM the middle finger and contact the BBB to Lemon Law it? Do I even have a good case for that?

TIA for any help! And if I should post this somewhere else for advice please let me know.

Like title says, I’ve found 3 vehicles, first a 2023 Yukon XL (denali ultimate), 48k miles, engine went out last year, replaced, comes with 150k mile engine warranty through GM. Dealer wants 64k. Plan is to keep the vehicle 8-10 years.

Other 2 vehicles are 2022-2023 Escalade ESV sport trims with 40k miles, both have engine replacements and same GM warranty as above. Dealer wants 59k.

Worth risking paying for a buyback/lemon law vehicle or no? Curious anyone’s thoughts of owning a vehicle with a branded title like this.

Can’t believe how bad this is getting.
Took truck in in the 22nd because it said “service high voltage system” got it back, they said it only needed an update. Leaving their parking lot everything started going back on.
Bought it back on the 25th as that was the next available appointment. I was told they needed a part and it “should be ready on the 29th/30th (Mon/tue).
All week no call, so on Fri the 3rd I call. Apparently they are still waiting on the part that hasn’t arrived yet and might be in the next week. But no guarantee.
Called the Chev Ev concierge for help as this is getting frustrating. They can’t help and can only send a customer service survey AFTER it is fixed. ( but who knows when it will get fixed.)
So now another week without truck with no actual date of when this mysterious part might arrive even though they should actually have a date if they actually ordered it.
Losing tons of money and cancelling plans every weekend because we don’t have the truck.
Was offered a Bolt ev as a loner or a rental truck. Neither are very helpful, definitely don’t have the extra $300/$400 for gas every weekend, (as we are at two weekends now) and a bolt definitely isn’t close to a comparable vehicle as a Silverado Ev.
My chev app is now showing more issues than what I brought it in with. So what is actually happening with my truck ?! Dealership said it is just sitting waiting to get worked on. Again waiting for this mysterious part with no known arrival date that just gets put from one week to the next week.

Prior to this we were looking to get another ev to replace wife’s SUV but definitely won’t be looking at chev anymore. A week and half later and no actual information or help Is beyond disappointing.

Battery would only charge to 66%
Dash said “service high voltage”
Regen stopped working.
A/c stopped putting out cold air

First appointment i mentioned others had similar issues on a Reddit form but was assured it was only an update issue.

I guess mentioning Reddit just made them mad lol.

Chevrolet should be doing better.

I have an appointment Tuesday to replace my brake booster and power steering. I know it’s difficult to give a firm answer but I wanted a ballpark. He said $600-800 on the HIGH end. I had them confirm again that this is for both with the parts, and he said less if it takes less. Their labor rate is $150/hr.

Is this real? Or have I just gotten used to being overcharged at other places?

Vehicle is 1995 GMC G2500. Thanks!

Hey I accidentally bought 5w-40 oil for my 2015 GMC terrain It was supposed to take 5w-30 but I only got 5w-40 can the ecotec handle it

What kind of gas mileage are y’all getting on your GMC Sierra’s? I’ve got a 2015 V8 SLE and a 2 inch level and get around 13.5 city driving. Seems kind of low to me just want to check out what other people are getting.

I currently own a 2024 Buick Envision and the lane keep assist is so bad it might as well not exist. If it intervenes at all, it ping pongs me back and forth in the lane. My 2019 Accord kept me dead center like I was on a rail.

I’m currently considering a 2025 Acadia and it does not have Supercruise. Is the regular lane keep any better on the Acadia than the Envision, or is it just a GM problem? Thanks.

Could us some help here. I’ve got a 2017 GMC Sierra 1500. When running the AC, no matter the mode, the fan starts and stops all through the drive. Not consistent either. Electrical gremlins are not my specialty. So thought I’d try here. Any help is appreciated. It’s too damn hot!

I have a 2018 GMC Sierra 5.3 with crank no start issue. I am able to get the truck to start with the air intake removed at the throttle body and the PCV tubes removed from the intake housing. As soon as I install one of the PCV lines or the intake to the throttle body, the truck stalls. I’ve tried running it with the MAF sensor disconnected, but it will not start. The filter is clean and not collapsed. I was unable to find any leaks or restrictions in the intake tube/housing.

Removed the PCV valve and performed a rattle test, does not seem stuck. Wondering if I’m dealing with a bad EVAP purge solenoid or a vacuum leak somewhere else in the system?

UPDATE:

Because I was getting so much back pressure at the PCV hoses I decided to remove the downstream O2 sensor as I suspected the 3rd cat was plugged up. It started first try. So yesterday I removed the 3rd cat and it ran well. Drove it around a bit no issues. Went to drive it again after some time and it stalled. Threw codes for low voltage on bank 1&2 ignition coils. I checked them all, inspected fuses and wiring, all was good. Let it sit overnight because I suspected the engine was flooded. Started up first try this morning. Drove around for 10 minutes and started getting sluggish acceleration. Was on my way home and it died again. This time throwing codes P0011 & P0016 for cam position and VVT. I am wondering if the ecm is on its way out or if there is maybe any chance that too much gas got into the oil when it flooded and it damaged the VVT solenoid?

2nd UPDATE:

Let it sit for a few hours and tried starting, still would not start up. Returned after letting it sit overnight, started first try. Let it idle to operating temp and stalled again, cranks will not start. Any idea what to look at before firing the parts cannon at it?

Thanks!
