2023 Buick Encore GX

I was driving in heavy traffic when I got a reduced power message. There was no where for me to go to get out of the traffic. This is the second time I've had this issue. I have already replaced the entire turbo several months ago. I took it to the dealer then. They attempted to fix it with just replacing part of it. It didn't fix. The cost to fix it at the dealer was more than I could afford so I took it to a different shop. All together it cost around $2000. Now it's happening again!!

Three nuts snapped, which secure the front muffler to the length of the exhaust system. The engine side of the exhaust pipe became disconnected and dragged along road, which occurred while driving the vehicle on a residential road. Steering was not impacted, however the pipe would have eventually come completely free, without driving directly to an auto-body repair shop.

I am reporting a serious safety issue with my 2023 Buick Encore GX that repeatedly shuts off while driving and doesn’t restart when auto stop is on, it leaves me stranded in traffic. The vehicle has been in the shop multiple times since February 13, and the issue has not been resolved. A service advisor has stated he is not comfortable putting me back in the vehicle and wants to help get me out of this car. I am requesting escalation, a case number, and immediate resolution. After having the oil changed in February, the check engine light came on soon after. Car had left me stranded prior to the battery being replaced. After 4 times in the same shop, they say a bad ground connection may now be the problem, however they also said they recharged the battery the visit prior.

When starting from a traffic light after the green light, the car made mechanical noises and would not accelerate above approximately 25 mph. It seemed obvious at the time that the transmission had failed, which was later confirmed after being towed to the dealership. There were no warning lamps or messages displayed; however, during the previous days, there were a few instances when the transmission "shifted" hard (this seemed odd considering it is a CVT transmission).

Component: Federal Safety Certification Label (49 CFR Part 567). Available for inspection. Summary: Vehicle was manufactured and sold brand new without the mandatory Federal Safety Certification Label. The omission was discovered during a professional trade-in inspection when the representative showed me where the label was supposed to be, but was missing from the car. The vehicle is currently non-compliant with federal safety standards, rendering it unmarketable. Confirmation: The manufacturing omission was confirmed by a review of historical authorized dealership service records. Photographs taken of the door jamb during routine service prove the label was never present. Symptoms/Warnings: There were no warning lamps or symptoms. I was never informed of this non-compliance by the manufacturer or authorized service centers during routine maintenance. Manufacturer Response: The manufacturer was contacted immediately via phone, email, customer service chat, and in-person to rectify the omission. However, the manufacturer failed to provide a resolution within the window of a time-sensitive trade-in valuation and tax credit package, causing the offer to expire. In subsequent communications, the manufacturer refused to remedy the non-compliance without charge, demanding payment for the label and labor in violation of 49 U.S.C. § 30120. The vehicle remains unmarketable and unused.
