When I come to a stop and the auto stop/start disengages the car makes a grinding noise

When accelerating to get on to highway pushing on pedal but nothing happens, have to get pushing up and down until it goes. Has done this four time's and dealer says Buick has no fix for it. Have almost got rear ended twice.

The contact owns a 2019 Buick LaCrosse. The contact stated that the engine fan failed to shut off after turning off the vehicle. The failure occurred while the vehicle was idling in a drive-thru with the temperature gauge reading that the engine was in the cold position. The driver then drove at speeds between 60 - 70 MPH; after arriving at the residence, the engine fan failed to turn off. The contact disconnected the battery, and all the system functions were reset, and the fan shut off. The failure had become more persistent over time. The vehicle had not been taken to the dealer due to the fault codes being erased after disconnecting the battery. The vehicle had not been diagnosed. The vehicle had not been repaired. The manufacturer was made aware of the failure, and it was confirmed there was no recall for the failure. The failure mileage was 56,000.

In October 2021, while driving, the car lost power. Several indicators displayed at the time, including: • Service Engine • Service Stabilitrak • Service Antilock Brakes • Service Transmission I managed to pull the car to the side of the road and restart it, but it was stuck in first gear. After several restarts it performed normally. I took the car to Miller & Sons, they told me they could not find a code and the car was performing normally at that point so there was nothing they could do. They told me if the car did it again, to bring it in immediately so they could get a code for the malfunction. Two weeks later, the same malfunction occurred, I took the car directly to Miller & Sons. Once again I was told they could not find a code or problem and I was sent away again. The third time this malfunction occurred, I was driving at 40 miles an hour and the car began to accelerate on its own. I could not brake, shift to park, shift to neutral, steer or apply the emergency brake. After about 15 seconds, the car shut down in the middle of the road. It could have caused death or seriously bodily injuries to me or others. At this point I had the car towed to Miller & Sons. I am told that while test driving the vehicle, it also accelerated on the mechanic [XXX], almost causing an accident again. At this point the told me they found 60 codes dating all the way back to the first incident, but they still did not know the problem, they replaced the Transmission Control Module in hopes that would solve the problem. It did not. In August, the same thing happened. They replaced the transmission control module again. About a month ago (September 13) it happened two more times. It is still sitting at Miller & Sons. This time I contacted GM for some assistance. I was using the messaging system (case number [XXX]) I was told a senior advisor was assigned to my case and that a TAC team would consult with the dealership to diagnose and correct the problem....

I OWN A 2019 BUICK LACROSSE E-SHIFT (VIN#[XXX]). OVER THE LAST 4-5 MOS. I HAVE HAD 3 INCIDENTS WHERE THE E-SHIFT MECHANISM HAS GONE INTO PARK WITHOUT TOUCHING THE SHIFT CONTROL. 1. FIRST OCCURRENCE - APPROX. 5 MONTHS AGO CAR WAS IN DRIVE AT VERY SLOW SPEED ENTERING PARKING SLOT WITH FOOT LIGHTLY DEPRESSED ON BRAKE. CAR CHANGED TO PARK ON IT'S OWN. STOPPED ABRUPTLY, GEARS GRINDING, JERKING ME TOWARD STEERING WHEEL. 2. SECOND OCCURRENCE - AROUND 10/10/20, CAR WAS IN DRIVE, FOOT LIGHTLY DEPRESSED ON BRAKE, WAITING TO MAKE LEFT TURN AT STOP LIGHT. CAR CHANGED TO PARK ON IT'S OWN. AGAIN THE CAR STOPPED ABRUPTLY, GEARS GRINDING, JERKING ME TOWARD STEERING WHEEL. I SCHEDULED APPOINTMENT WITH DEALER MAINTENANCE ON 10/13/20. THEY COULD NOT REPLICATE THE PROBLEM. ASKED FOR ME TO RETURN THE CAR SO THEY COULD HAVE OVERNIGHT. DUE TO COVID ESCALATION HAVE NOT SCHEDULED APPT. 3. THIRD OCCURRENCE - ON 12/11/2020, I WAS WAITING AT A RED LIGHT, CAR IN DRIVE, FOOT FULLY DEPRESSED ON BRAKE, AND THE CAR SHIFTED TO PARK ON IT'S OWN. I HEARD THE CAR LOCKS CLICK, AND WONDERED WHAT CAUSED THAT. WHEN LIGHT CHANGED AND I TRIED TO ACCELERATE, THE CAR DID NOT MOVE, AND IT WAS THEN I NOTICED IT WAS IN PARK. I INTEND TO TAKE THE CAR BACK TO THE DEALER FOR THEM TO SEE IF THEY CAN REPLICATE. THEY HAD NOTHING IN THEIR DATABASE ON 10/13/2020 REFLECTING OTHER COMPLAINTS. I'M SOMEWHAT SKEPTICAL THEY CAN REPLICATE DUE TO THE RANDOM OCCURRENCES. BUT IT DEFINITELY SEEMS TO BE IN THE SHIFT PARK COMPONENT OF THE CAR I AM NOW VERY HESITANT ABOUT DRIVING THIS CAR. SINCE IT HAPPENS RANDOMLY, AND ABRUPTLY, WITH NO FOREWARNING, I AM CONCERNED FOR MY SAFETY. MY QUESTIONS ARE: 1. HAS ANYONE REPORTED A SIMILAR PROBLEM TO YOUR GROUP? 2. WHAT OTHER INFORMATION DO YOU REQUIRE? 3. WHAT OTHER ACTIONS SHOULD I TAKE? 4. WHAT OTHER GROUPS CAN I CONTACT TO INQUIRE ABOUT THE PROBLEM? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

OCCASIONALLY THERE IS A LOUD SOUND IN THE CABIN OF WATER SLOSHING BACK AND FOURTH UNDER THE DASHBOARD. SOME DAYS IT WILL HAPPEN WHEN THE ENGINE STARTS. OTHER TIMES, IT IS AFTER DRIVING SEVERAL MILES. SOMETIMES IT HAPPENS A FEW DAYS IN A ROW. OTHER TIMES IT WILL GO A WEEK WITH NO NOISE. THE GM MECHANIC VERIFIED THAT THE COOLANT LEVEL IS FINE. IT HAPPENS WHEN THE CAR IS STATIONARY OR MOVING. I HAVE NOT HEARD IT AT HIGH SPEEDS.

When I get to a stop sign, and a stop light, when trying to accelerate after a complete stop, the car would struggle to accelerate to go forward. Where the shifting gears would start blinking, and the warning lights (engine power reduced, engine light, and the traction safety collision light) would display itself making it misfire and impossible to even go forward while pressing the gas pedal. It put me and other drivers at a safety risk because it would roll backwards after taking my foot off the breaks to accelerate where it would almost hit drivers behind me at the stops as well as them almost mistakingly hitting me in the back when my break lights stop reflecting when trying to accelerate at stop lights with traffic. I have had it diagnosed with the recall codes N20231344O GM # 20V668000 NHTSA # 18V576000 18V358000 But the dealships are saying there aren't any recall for the vehicle. This issues is ongoing.

The contact owns a 2018 Buick LaCrosse. The contact stated the hand controls were not working properly. While driving, the accelerator pedal was depressed, but the vehicle failed to respond. The engine power reduced message was displayed, and the check engine warning light was illuminated. After several attempts, the codes were reset, and the vehicle worked as designed. The contact linked the failure to the Special Coverage Campaign: N182188250. The vehicle was taken to an independent mechanic who disconnected the hand controls and informed the contact that the controls were operating as designed. The vehicle was taken to the local dealer, where it was diagnosed, and determined that the accelerator pedal position sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving at 55 MPH, the vehicle lost motive power and decelerated to 15 MPH. The message “Engine Power Reduced” was displayed, and the check engine warning light was illuminated. The vehicle was taken back to the same local dealer, where it was diagnosed and determined that the accelerator pedal position sensor needed to be replaced; however, the failure persisted. The manufacturer was contacted, and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 26,600.

The 3.6 liter engine in my 2018 Buick Lacrosse Avenir only has 53,939 when we experienced a thermostat failure. The engine temperature was dead cold, and the dual electric fans were running non-stop. When I scanned the trouble code, I found PO128 which points to a faulty thermostat. Because the thermostat is buried under the intake manifold, we had the local Buick dealership replace it at a cost of over $800.00. I don't feel that a car with so few miles should be experiencing a thermostat failure. But this seems to be a common problem with the GM 3.6 liter motor according to a number of Buick forums that I read after the problem occurred.

The contact owns a 2018 Buick Lacrosse. The contact stated while driving at an undisclosed speed, the vehicle hesitated to accelerate while the accelerator pedal was depressed. The contact pulled over and checked underneath the vehicle. The contact discovered that the START/STOP accumulator endcap bolt had detached, causing transmission fluid to leak onto the ground. The vehicle was towed to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that in 2021, he detected an abnormal fuel odor coming through the air vents while driving. The brake pedal also stuck while depressed, and the rear brake pads needed to be replaced frequently. The contact stated that the vehicle was taken to an unknown dealer in 2021 for the fuel odor, and an unknown fuel system part was replaced. The contact related the failures to NHTSA Campaign Numbers: 20V668000 (Power Train), 18V358000 (Fuel System, Gasoline), and 18V576000 (Service Brakes, Hydraulic); however, the VIN was not included in the recalls. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was 161,188.

Thermostat failure at 56,000 miles.

The contact owns a 2018 Buick Lacrosse. The contact stated that the key fob failed to open the doors and the vehicle was unable to be restarted. The failure had recurred on several occasions. The contact stated that the batteries in the key fob were replaced but the failure persisted. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 100,000.

I have brought my 2018 Buick Lacrosse to two different Buick dealerships who say that even though a special instruction letter was recognized and a recall was observed, because my check light went out and the codes on the car where cleared, they will not fix either recall. On three different occasions, the car slowed down to a crawl speed, the check engine light went on and the brakes applied themselves. Also across the dash was displayed 'service transmission'. I thought it was the accelerator pedal position sensor, but it may be a transmission problem. I've had it towed on three different occasions and had the battery replaced. Neither dealership will not fix the problem, however.

When I tried to stop at the traffic light, the car suddenly accelerated and went forward. At that time, the car brake was engaged. On the same day; When I tried to go forward at the traffic light, the car suddenly accelerated. The dealer service center said, "We cannot find any issue with the transmission."

2018 BUICK LACROSSE. CONSUMER WRITES IN REGARDS TO VEHICLE SHUTTING OFF SUDDENLY. *LD THE CONSUMER STATED THE BATTERY WAS REPLACED, BUT THE FAILURE RECURRED. THE DEALER UPDATED THE SOFTWARE , BUT COULD NOT GUARANTEE THE FAILURE WOULD NOT RECUR. *JS

I RECEIVED A NOTICE FROM GM THAT MY VEHICLE WITH THE ELECTRICAL CONNECTION TO THE ACCELERATOR PEDAL WHICH COULD CAUSE A A REDUCED POWER AND ACCELERATION CONDITION. HOWEVER, THIS IS NOT A RECALL AND I SHOULD NOT SEEK A REPAIR UNTIL I HAVE EVIDENCE THAT MY VEHICLE HAS THIS PROBLEM. THIS SOUNDS LIKE A SERIOUS SAFETY RISK TO ME. IF THIS CONDITION OCCURS WHEN I AM MERGING INTO TRAFFIC ON AN INTERSTATE, IT COULD CAUSE A SERIOUS ACCIDENT. APPARENTLY OWNERS ARE SUPPOSED TO WAIT FOR SUCH AN OCCURRENCE IN ORDER TO GATHER EVIDENCE OF A NEED FOR A REPAIR. I WANT GM TO TELL ME IF MY VEHICLE HAS THIS DEFECT IN ADVANCE AND, IF SO, REPAIR IT BEFORE THE DISASTER OCCURS.

IF STOPPED UPHILL AND THE AUTO STOP ACTIVATES, WHEN YOU RELEASE THE BRAKE THE CAR CAN ROLL BACK, AND THE WAY PEOPLE STOP ON TOP OF YOU THESE DAYS YOUR CAR CAN ROLL BACK INTO THEM AND YOU HAVE TO REPAIR THEIR CAR. PLUS IT ACTUALLY TAKES MORE GAS THAN MY V8 2016 GMC SIERRA THAT DOESN'T STOP WHEN TRAVELING FROM MY FUELING LOCATION TO MY HOME, PER THE CARS OWN COMPUTER SYSTEM

I SENT THIS EMAIL TO THE SURVEY FOR RANDY MARION DEALERSHIP ON STATESVILLE RD HERE IN HUNTERSVILLE NC. AGAIN I DO NOT WANT THE VEHICLE BACK AS IT IS TOO MUCH RISK FOR ME, MY FAMILY AND MY WORK. IT PUT ME IN A DANGEROUS SITUATION FROM BEING STUCK IN THE STREET AND DEALING WITH AN ANGRY PASSENGER. WE MUST GET THIS RESOLVED IMMEDIATELY. I AM LOSING MONEY. I NEED A DEPENDABLE VEHICLE. THE SALES PART WENT AS EXPECTED. A LOT OF SMILES AND VERY ENGAGED IN CONVERSATION. THE SALES GUY MIKE WAS VERY NICE. NO PRESSURE. THE PROBLEM IS AFTER THE CARE WAS SIGNED FOR. AFTER THE EXCITEMENT OF GETTING A BRAND NEW VEHICLE I REALIZED I PAID TOO MUCH AND DIDN'T UNDERSTAND ALL THE CHARGES THAT JACKED THE TOTAL UP SO FAR. HOWEVER THAT'S NOT MY ISSUE. MY ISSUE IS THE BRAND NEW CAR IS SHUTTING OFF IN THE MIDDLE OF THE STREET. IT GOES COMPLETELY DEAD. LEAVING ME STRANDED. IT HAPPENED THREE TIMES ON 10/5. THE BRAND NEW VEHICLE IS PPUTTING ME IN A DANGEROUS SITUATION FOR ME, MY FAMILY AND MY CLIENTS. SO I'M NOW LOSING INCOME AND IT ALSO CAUSED ME TO HAVE A BAD CUSTOMER SERVICE EXPERIENCE WITH A CLIENT WHICH EFFECTS MY PROFESSIONAL REPUTATION. THE PROBLEM WITH THE VEHICLE IS MAJOR AND A SERIOUS SAFETY ISSUE. YOUR SERVICE TEAM IS WORKING WITH GMC ENGINEERS TO FIGURE OUT HOW TO FIX THE PROBLEM, HOWEVER I DO NOT WANT THIS VEHICLE. YOUR SALES MANAGER STEVE SAYS THIS IS UP TO GMC TO DETERMINE IF A VEHICLE CAN BE EXCHANGED OR NOT. THIS IS COMPLETELY UNACCEPTABLE FOR ME. I WORK TOO HARD AND A LOT OF PEOPLE DEPEND ON ME.

While driving down the road goin around 45 mph all of a sudden my steering wheel got so stiff I could hardly steer the car off the road and out of traffic. I didn't hit anything, my power steering just stopped. I put the car into park and turned off the ignition after a few minutes I started it back up and my steering was back to normal. This has happened to me 2 times driving my 2016 Buick Lacrosse Sport. It's Dangerous and Honestly if your not paying attention it can cause a accident.
