Maybe this will help someone. My TB started throwing the same error for Engine Power reduced. Took it to the dealership and they said it needed a new computer program, which they did. About 50 miles later, the EPR message came up again. Took it back to the dealership and they said they had a bulletin that said the Turbo Solenoid? needed to be changed. They did that and 27 miles later, the EPR message came up yet again. Took it back to the dealership today and they say a new bulletin says to replace the turbo and components associated with. Mine has 23K miles on it and I am hoping this is the permanent fix. Fingers crossed.

I realize this is a little over a month late, but I also have a 2021 trailblazer with about 29,000 miles that's doing the same thing. I have an appointment Friday at the dealership. Did anything ever come of your situation?

Mine has been at the dealership for 10 days and probably going to be for about 2 more weeks as they are awaiting parts according to them. I love my TB, but if the Turbo fails this early (23k miles), I am afraid it is going to do it again in another 20K or so. I think I am going to trade mine before the warranty is up.

Hi guys! I’m glad I’m not alone with this issue. I got my 2021 TB back from the dealership yesterday and the light went on again today. I have the engine power reduced message too, but the speed is not limited or anything like that. You can definitely feel that it’s less powerful tho. I called them and told them what you guys said here and I’m bringing it back to them tomorrow. Wish me luck!

Did they replace the entire turbo or just the wastegate solenoid....that's what they did to mine the first time.

Going on 3rd week parked at the dealership with parts expected on 08/01. Got a call yesterday that parts at minimum will be shipped on 08/17. So basically 6 weeks with no vehicle counting the other 2x it was in the dealership to begin with.

Oh dang! I’m on week 4 and it doesn’t look good for me as well. Parts are on back order and they started a nationwide search for it, but so far we don’t have the parts, ETA, or anything. I just open a case with GM and I’m waiting for a call. Also, I’m opening a Lemon Law claim. This is a nightmare!

yes I did the same....

Latest update from GM and the dealer. Parts were supposed to be at the factory on 08.18.2022 and arrive at dealership on 08.25.2022. Service manager texted me this morning and GM is now saying mid-September is the absolute earliest that they will get parts. This is the 5th time they have changed the arrival date of parts so I presume mid-September means mid-October. I have applied for a buyback from GM but they say the car has to be fixed before they will consider a buyback. They have had my car in the dealership since July 18th and by the time it's fixed it will be close to 60 days. My suggestion, and as much as I loved my Trailblazer, get rid of it now before you run into the same issue. My lawyer is now involved filing a Lemon Law claim. Will keep you posted on how it turns out......so frustrating......
