Engine

“2014 Buick Regal GS AWD sedan, second owner. Car was purchased as a certified used from Buick dealer in 2018 with 40,xxx miles. Car now has 137,xxx miles, no longer under extended warranty. Have had all regular maintenance done and have records. Aside from normal wear and tear, no prior issues with car. Car engine suddenly started to run rough, Check Engine light came on while driving 65 mph, sudden loss of engine power and car died on the highway causing congestion and vehicles to swerve on highway, loss of steering control, pulled over. Car was able to be restarted but running rough, engine light on, severe reduction in power. Talked with nearest dealer, they said to not drive car. Had local GM mechanic do inspection, computer codes indicated loss of compression on cylinder 3, misfire. Compression check and bore inspection indicated loss of compression on cylinder 3, valve failure/damage, oil in the turbo, requiring complete rebuild or replacement engine and turbo. Review of TSB from GM indicated this is a known issue, engine to be replaced.”

“TL* THE CONTACT OWNS A 2014 BUICK REGAL. WHILE APPROACHING THE DRIVEWAY OF HER HOME, THE CONTACT ATTEMPTED TO ENGAGE THE SHIFTER INTO THE PARK POSITION; HOWEVER, THE VEHICLE SEIZED WITHOUT WARNING WHILE THE KEY WAS STUCK IN THE IGNITION. THE CONTACT ATTEMPTED TO DEPRESS THE SHIFTER LEVER AGAIN, BUT THE FAILURE RECURRED. THE CONTACT DID NOT ENGAGE THE EMERGENCY BRAKE. THE FOLLOWING DAY, THE CONTACT ATTEMPTED AGAIN TO PLACE THE SHIFTER IN THE PARK POSITION WITH THE KEY STILL IN THE IGNITION OVERNIGHT. THE CONTACT MANAGED TO GET THE GEAR TO SHIFT AND, ONCE RESTARTED, THE VEHICLE RESUMED NORMAL OPERATION.

Service brakes

“AFTER COLD START THE BRAKE SYSTEM IS WEAK TO NON EXISTENT. WE HAVE A SLOPE OF APPROXIMATELY 25-30 DEGREES AND THIS CAUSED US TO GO INTO OUR NEIGHBORS YARD WHEN THE BRAKES ONLY SLOWED THE VEHICLE AND COULD NOT BRING IT TO A COMPLETE STOP. WE ARE CURRENTLY WORKING WITH OUR LOCAL DEALERSHIP TO GET THE PROBLEM FIXED, HOWEVER DIAGNOSIS IS PROBLEMATIC DUE TO THE FACT THAT IT ONLY OCCURS ON A COLD START AND THEN BECOMES A NON ISSUE. CURRENTLY YATES BUICK IN GOODYEAR AZ HAS BEEN DISMISSIVE AND UNHELPFUL WITH THIS PROBLEM AND BUICK CUSTOMER CARE LINE IS EQUALLY UNHELPFUL. I WILL UPDATE IF I CAN FIND A MECHANIC THAT CAN DIAGNOSE THE PROBLEM.”
