2016 Buick Encore Complaints

Acceleration was reduced immediately on the freeway after the check engine light came on the day before with a P0299 code for turbocharger repair. Now the vehicle will not start and the dealership service said an additional code of po366 is now showing. Are these related? The turbocharger has an extended special coverage, but not engine repair that is likely the result of the turbocharger failure.

In 2021, My ex husband received a notice from Buick extending the warranty to 120,000 on the Turbo Charger fuel injector due to failure in many vehicles. It was not included as a recall. In the State of Texas, vehicles must have an annual inspection to remain legal to drive. Each vehicle receives an annual Sticker. My sticker and inspection were due in July. In May of 2024, my check engine light came on. I took it to Autozone to diagnose, and they said it was the turbo charger. Since I had no idea my ex-spouse had a letter, I purchased fuel injector cleaner and did this every week. Chevron 92 has always been my gas of choice. Unfortunately, it only cleared the engine light for a few days and my vehicle failed inspection at 120,000 miles. I took my Buick Encore to a traveling mechanic, who cleaned the injectors (supposedly), and after driving about 100 miles and in July finally passed inspection to avoid a citation. At 122,00 miles, on [XXX] I drove my Buick to Dallas Texas,...

2016 Buick Encore VIN [XXX] approximately 60,000 miles. The vehicles turbo had a catastrophic failure pushing oil into the engine, and the catalytic converter causing extensive damage to both. The description from the first mechanic shop, I took it to descripted it as the turbo exploded, spewing oil everywhere. Buick knows the turbo engine is faulty and they issued a 'special' warranty, however the warranty doesn't cover the damage caused by their faulty turbo engine. There wasn't anything I could've done to prevent this. In fact, the GM dealership replaced the turbo and that turbo failed and had to be replaced. I've been asked to cover the cost of repairing the engine, catalytic converter and clean the oil that sprayed the engine compartment. In hindsight, Buick should've issued a full recall on the turbo. They made a business decision not to recall the turbo, but they need to accept responsibility. Living in rural Northern Wisconsin, we are fortunate that this didn't happen...

The turbo on my 2016 Buick Encore hasn't been working right for about a year. My engine light has been on consistently everyday for about 8 months. I've taken it to the dealer to get it repaired, and there is a bulletin - Reference Number A212338300 - but for some reason my VIN doesn't meet the requirement of the turbo replacement - even though the bulletin is for a turbo replacement. Why is my turbo NOT covered by the bulletin? Clearly there is an issue with the part since a bulletin exists in the first place.

After investigating the failure, the contact related the failure to Service Update: 43210. The manufacturer was not notified of the failure. The failure mileage was 100,000. The VIN was not available.
