2012 BUICK ENCLAVE Complaints

While driving, the vehicle suddenly and without warning experienced a severe, dangerous loss of acceleration. The dashboard immediately displayed a "Reduced Engine Power" warning message along with a "Service StabiliTrak" light, forcing the vehicle into an immediate electronic fail-safe "limp mode." This sudden, drastic reduction in engine power severely restricts the vehicle's ability to maintain safe roadway speeds, accelerate from a stop, or merge safely into traffic, posing an immediate rear-end collision hazard to myself and other motorists. Furthermore, the defect simultaneously disables critical active safety systems by shutting down the StabiliTrak and Traction Control networks. A diagnostic scan revealed code P2138 (Accelerator Pedal Position Sensors 1-2 Correlation Not Plausible). Investigation reveals that this is a widespread, systemic safety defect caused by design flaws in the vehicle's body. Rainwater and moisture from clogged factory sunroof drains or cowl seams leak directly down into the interior cabin wall, pooling into the primary instrument panel-to-body wiring harness block (X218 connector) in the driver's side footwell. This water intrusion causes green corrosion on the delicate pins, short-circuiting the 5-volt reference sensor circuit for the throttle controls while the vehicle is in motion. General Motors is fully aware of this exact defect and has documented it internally via Technical Service Bulletin (TSB) #10-00-89-017H (and related GM TSBs). Because this defect causes unexpected, immediate engine failure and disables traction safety networks while driving, it constitutes a severe safety hazard that should be escalated to a mandatory safety recall.

Fuel pump, throttle body, and High pressure fuel pump. Car makes door lock noises and’s completely cuts off while driving over 20 times now on highway and all. Have gotten several things repaired in addition to these listed things and after repairing car works fine for a few months then needing to be replaced again. No codes are being given other then abs, traction control warning and stabilitrak

Steering wheel airbag warning. Seat belts fraying. The underneath welding for the support bar, potentially the rear axel, came unwelded.

The contact owns a 2012 Buick Enclave. The contact stated that while driving at various speeds, the vehicle lost motive power and hesitated while attempting to accelerate and depressing the accelerator pedal. During the failure, the check engine warning light momentarily illuminated. The vehicle was taken to a local mechanic who was unable to determine the cause of the failure. Additionally, while opening the rear liftgate door, there was a clicking sound coming from the driver's side rear liftgate door strut. The cause of the failure was not yet determined. The manufacturer was notified of the failure, but no assistance was provided. The local dealer was not contacted. The contact was informed that the VIN was not included in NHTSA Campaign Number: 15V415000 (STRUCTURE). The failure mileage was 118,000.

My car has shut off multiple times , electrical shorts, intermittent no start, intermittent misfires all the time but randomly , injector codes even when replaced and injectors are good , yes come check out my vehicle no shops can find out what's the problem practically the whole front end has been replaced and problems still happening it is congruent with a recall but shows nothing from vin

When pulling onto a county road with traffic the transmission kept slipping and the engine would rev higher. It took a lot longer to get up to speed and the cars behind me had to brake quickly.

Driving along and engine power reduced causing car to slow significantly - like downshifting two gears. Lights / traction control lights came on dash. Errors flashed - "Traction Control Off", "Service Stabilitrak", "Engine Power Reduced" All of this not only caused a slight bit of confusion, but placed us in danger with the flow of traffic. A repair shop replaced the gas pedal, however issue persists. Research indicates the throttle body sensor might be at fault - so we replaced this. Issue persisted, so I spent time online and found a GM TSB indicating a known issue and extending the warranty 10 years or 120K miles for P2138 Code. At this point, this issue persists intermittently, so we do not consider the vehicle safe to drive.

The contact owns a 2012 Buick Enclave. The contact stated that while driving at various speeds, the vehicle lunged forward while accelerating. The failure was more persistent at speeds of 40 MPH and lower. There were no warning lights illuminated. Additionally, while turning the steering wheel to the left or the right there was a clunking sound coming from the steering wheel. The vehicle had been taken to an independent mechanic where it was diagnosed that the rack and pinion needed to be replaced. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The failure mileage was 83,000.

What does it mean when my car says service StabiliTrak and service traction control? Its main function is indicating that the traction system has been turned off manually to remind you to turn it back on when necessary. However, the StabiliTrak warning light may also signal potential damage to vehicle components that allow the system to work effectively. Loss of Power to Engine, Can't stear, feels like its about to blow up. It seems very usual for the Enclaves, Traverses and Acadias. And I had the same problem out of my 2014 Traverse LTZ

If any warning light comes on such as my add air to a tire (it always tells me the wrong tire), all of the warning lights start flashing. Things shut off (radio, dash lights, backup camera) and sometimes the car will shut completely down and come back on. I am afraid to drive very far.
