We have experienced multiple recurring issues with our 2024 GMC Acadia that raise significant safety concerns and affect the vehicle’s reliability and overall operation. First, the brake system exhibits persistent squeaking, even at low speeds or light applications. The dealership has inspected the brakes but the noise continues, raising concerns about premature wear or improper brake function. More concerning is the behavior of the automatic braking system while reversing. The system has repeatedly activated the brakes without any obstacle, vehicle, or person behind us. These unexpected braking events have created both physical and psychological stress for occupants and pose a real risk of causing a rear-end collision from another driver who may not anticipate sudden braking. Due to this hazardous condition, we have been forced to deactivate the automatic braking feature entirely, defeating a critical safety system the vehicle is equipped with. Additionally, the engine frequently runs rough during cold start and the initial warm-up period for the first couple of minutes. This rough operation is inconsistent with expected behavior for a new vehicle and has not been fully resolved despite service visits. The TPMS sensors have also been problematic. Several sensors have already been replaced by the dealership, yet we continue to experience intermittent TPMS faults involving at least two wheels. This results in repeated warnings, loss of real-time tire data, and uncertainty about actual tire pressure conditions while driving. We also experience rattling noises from the interior trim near the door seals whenever there is a cross breeze or windy driving conditions. This appears to be a structural or insulation-related issue. We have others, but this space only allows for 2000 characters, and after writing this sentence, there are only 113 characters remaining.

I bought a brand new GMC Acadia at Thompson GMC in Raleigh NC. From day 1 I have been having a issue with the tire pressure sensors disconnecting from the system. Thompson GMC was giving me attitude for bringing it back so many times so I brought it to Leith GMC in Wendell NC for diagnoses. Both shops referred to GM TSB (Technical Service Bulletin) PIT6188 which they both tried the reprogramming with no such luck. I was advised to wait for GM to come up with a fix and refused a loaner for the time unless I paid (GM customer care confirmed I would have to pay up front for a loaner). It is now 6 months later and I am still driving a vehicle where lights still come up on the dashboard and no fix. I get no where with the dealerships and GM customer care (case # 9-14086984106) advises me I have to keep bringing it to the dealership. No one can give me a update on when this will be fixed and I am constantly getting a run around. Please help.

EA26006 · Electronic Brake Module Component Failure

Opened Aug 21, 2026 · No close date supplied

Status: open (inferred from source dates) · Service Brakes

On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM’s eBoost system to resulting in safety-related outcomes. At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles. ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system.
