There are 2 owner-reported engine complaints for the 2020 Buick Encorein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Defective "TURBO CHARGER" at 38,091 miles. The defective worn-out or damaged turbocharger was removed from the engine and a new one was installed at a cost of $1816.00. This part should not wear out at 38,000 miles. My mechanic informed me that this is common in the Buick Encore vehicles to experience a defective "TURBO CHARGER" at low vehicle mileage.
I am co-owner of the vehicle. My daughter was driving the SUV when the Check engine light came on. There was no warning whatsoever, and the turbocharger has gone bad . Prior to the light eliminating there was nothing wrong with the suv. I was driving the suv when the check engine light came on. I also own another 2020 Buick encore where this also happened. I was driving the vehicle when the check engine light came on with no prior warning and it was a failed turbocharger. There is something wrong with these vehicles .
