2021 Buick Encore Gx

While driving check engine suddenly illuminated following by a "warning reduced engine power" message. Car began driving sluggish and driving over 35mph caused serious trembling. After multiple diagnosis with several engine codes pointing to issues with ECM, and mass air flow sensor, and the wiring affliated . I took the vehicle to the GMC dealership to get vehicle serviced and was told the wiring had broken and melted which caused the check engine to come on and the vehicle to drive the way it did. The cause was the zip tie being tied too tight as stated in GMs own bulletin number 22-NA-008. This should be a bulletin it should be a recall!

The contact owns a 2021 Buick Encore GX. The contact stated that during a routine oil change at the local dealer, the contact informed the dealer that while in the park or shifting to park, the engine was shutting off unexpectedly. The message to “Shift to Park” was displayed and the vehicle was difficult to turn off. The contact wiggled the ignition to shut off the vehicle. There were no warning lights illuminated. The failure persisted over time. The contact was concerned about being stranded due to the failure. The local dealer was contacted, and it was determined that there was no warranty or recall coverage on the vehicle. The vehicle was not diagnosed or repaired. The contact had scheduled an appointment for a diagnostic test. The manufacturer was contacted and confirmed that there was no warranty coverage on the vehicle, and no assistance was provided. The failure mileage was approximately 17,500.

This is an ongoing issue that I have brought to the NHTSA's attention before, which resulted in a special coverage program being issued; however, now GM is not willing to assist me with the special coverage program due to a branded title (used vehicle), and the condition is only getting worse. Tonight, on August 16th, my vehicle experienced a complete loss of power, including engine functionality and fuel/propulsion systems. This stems from the original complaint I filed last fall (11614068) in relation to the turbocharger. I was advised by GM that they would not service my vehicle multiple times by rude supervisors, as my vehicle did not qualify under the special coverage because it's not a "safety issue:", and that the NHTSA has not issued a safety recall for this issue, when it's a safety issue. This is outrageous, and I URGE the NHTSA to look into the severity of this issue. It's only a matter of time before I am on the highway when my vehicle experiences what it did tonight. A complete loss of power, engine functionality, and the fuel/propulsion systems. I already had a near-death experience while driving on the highway when my engine power was reduced, which caused me to go from 65MPH to 40MPH in seconds on a highway, in the left lane, and I almost got rear-ended by someone going 75MPH. This is a safety issue, and it's not just impacting me. I find it so misleading that GM sent me a legal letter stating they knew there was an issue with the turbocharger and that they would take care of the repairs at no cost to me. The first line on the legal document states, ' Your satisfaction with our product is important to us," unless your car is used and has a branded title. There is nothing on that special coverage notice that explicitly states your title must be clean. I urge the NHTSA to issue a safety recall on the turbocharger so other Americans like me don't have to spend months going back and forth to get a simple repair done, an essential safety repair.
