   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.

10. Filed Jul 9, 2024Failure Apr 1, 2024Citronelle, ALEngine

    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.

    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.

    I purchased this vehicle (used)on 01/12/2021. 5 weeks later the brakes pedal went to the floor. It has done this randomly several times. Usually I can get the car stopped, put it in park and pump the brake pedal a few times and the pedal will be back to normal.When this happens it's usually at a low speed and I can get the car stopped but it takes a while. I have attempted to talk to Gen. Motors at Detroit seeking information as to how can I repair this problem. I got no help from Detroit. My local Buick shop manager tells me it could be any number of things. Maybe a sensor or something in the brake system or a vaccuum problem. I need to know what to do to fix this problem before I get into a wreck.
