2015 Buick Encore: check engine light

Filed Jun 26, 2026 · Engine, Fuel system · IN

The turbo in my vehicle has a check engine light come on and than the engine does no act right. The repair shop that looked at car stated that the manufacture knows this is a known issue and they have not made a recall as several cars my year range has this going on. If this is a known issue why is there no recall. I worked had for my car and I can not afford the repair of a know issues with the turbo as it cost a lot and I should not have to cover this as it is apparent this is a manufacture defect that is known. It puts me as risk as the car is not preforming properly and it jumps and does not go properly when it has the issue arise. I will get hit for not going after I come to a stop and will not accelerate properly. This issue appeared 2 months after I purchased the car and I took it to a shop who told me he has tried to contact Buick to cover the repairs for others and gets no where. I think that the manufacture knows and will not repair something that is not the owners fault but there shafty part and they know this as it was a recall in other years of my vehicle.

My check engine light came on so I took it to a repair shop. They put it on their Diagnostic System Check Computer and the code #PO299 came up. After further inspection and investigation, the failed part is the Turbocharger- A1140104N. This vehicle's, vin number, model year and mileage qualifies it for warranty replacement and labor for the faulty part. However, because it is a Buick and not a Chevy the dealership is not authorizing the repair, even though it is the exact same system and part that is being replaced in the Chevy models. Without this part functioning properly, it affects performance and the car's ability to accelerate when needed which makes it a hazard to drive if you should need to accelerate quickly.

The turbocharger on my car is failing and had a verified check engine light code PO299. The car is a 2015 with low miles, only 53k. This is an obvious manufacturer defect/defective product with an estimated cost of $1500.00 to replace, according to an ASE independent auto shop I use for all my vehicles. The car is unfortunately not under any warranty anymore, to my knowledge. There is no recall on this part but online on Buick forums and other credible sites, you will find owners of the same exact car reporting independently, the same failing part issues. I am the second owner of this car and bought it used in 2021 from Carmax. Since then, I have spent $$$ to fix random necessary repairs that are defects of the car but not on recall. Recently, the ac went out and that was over $500 alone. Prior to that an 02 sensor and sparkplug went out, etc. I want GM to reimburse me for the repair cost of the failing turbocharger on this low mileage vehicle as it is without a doubt, a manufacturer defect needing repair to prevent the engine from failure and a total loss! I contacted a GM/Buick agent and formal complaint and request for reimbursement. I am now waiting for up to two days for a "senior agent," to contact me back and discuss further options, if any. Until then, I am without a car with two kids at home and this defect is unsafe and a financial burden to me and my family. This is a known issue on this vehicle model and should be covered under a recall from GM!
