Lemon Law
 

Brand new 2023 Buick Envision only had it 3 months and the turbo went out. They have no part to fix it and don’t know when they will get the part. It’s been two months now.

And have they been providing you with a rental car for those two months??

The 2025 Envision has been in production since August (I don't know if they're available yet in the USA), so yours was apparently a left-over when you bought it? It hasn't been a huge seller for Buick. If I'm not mistaken, it is the only Chinese manufactured vehicle sold by the Big Three. I believe the entire drivetrain is produced solely in China, so I'm not surprised there are problems with the parts supply chain.

Keep in mind, with the Lemon Law, you're going to pay for the Depreciation/Mileage on the car. You're not necessarily going to get back what you paid ... you're going to pay for what you've used.

A lot of missing details. Did the dealer supply a loaner? Then just a minor inconvenience. I would call the manufacturer. Not available part? Good chance they can find it for you. It is possible yours failed because they are all defective. Possible your dealer has unpaid bills and is on credit hold. Sounds like A RUN AROUND. Were it ME, I would show up at service counter when they are busy. State your ISSUE politely but LOUD AND CLEAR. Demand to speak to the manager-get names etc

Far as attornies the bar association will give you a list of names. Easy to look them up on the internet. Honest review? Based on experience I have a negative opinion about attornies and our legal system

Amusing way to look at it. Anything will eventually need service. our current world things are not made to be serviced. Cars? Well you need to take the engine out to change the 4th spark plug.

Does not help BUT due to government controls-pollution safety etc you cannot bypass parts. A turbo is a high speed fan that is powered by engine exhaust. Imagine a high speed fan run by hot engine exhaust. Lubrication is a nightmare. Car computer may prevent you driving the car without it working.

I suggested contact the manufacturer. Today so much is done by computer. The deale orders by part number. May not be a BRAIN in the procedure. PN xxxxxxxxxxx for you may not be avail.
No one reads REPLACED BY PN...............
