On October 23, 2026 at about 7:25 AM, while my wife was driving our leased 2025 GMC Acadia (20,773 miles) with our son in the car, the vehicle displayed 'Brake assist failure. Press hard to brake. Speed limited.' The ABS and traction control warning lights came on and the brake pedal became very hard to press due to loss of brake assist. No crash or injuries occurred. This failure matches the eBoost electronic brake control module issue under NHTSA Engineering Analysis EA26006 covering 2024-2026 GMC Acadia. My wife is afraid to drive the vehicle. The vehicle is currently at the dealer for repair. I am requesting that NHTSA record this incident and that GM be required to remedy this safety defect and release us from the lease.

I was driving my car and my brakes felt weird. Then warning lights came on and my car told me that my brakes weren’t working and I would need to push them hard to stop. I put on my hazard lights and turned into a side street and was able to safely stop in the parking lane next to the curb. I shut my car off and then turned it back on. At that point, everything looked normal except for the engine light was on. I started driving again and within less than five minutes, the brakes went out again. I again was able to make it to a side street and stop, but was in a no parking zone. I was able to slowly make it into a parking lot and safely into a spot.

Engine cooling system malfunction, Ive had to receive maintenance on my Acadia 2025 elevation 3 times in the pass 2 months for the same issue, The coolant system. This is becoming a reoccurring issue that needs to be investigated thoroughly. Ive had to get a rental car all 3 times, and this is becoming frustrating and financially draining. My biggest concern is what is to happen once my warranty expires? guess I'll be paying a note and repair cost until a recall is opened on this issue and then will have to wait for reimbursement. This is horrible to say this car was made 2 years ago. Attention is needed on this defective part. I'm so frustrated to I might just trade in this vehicle. I pay for dependability and reliability in the amount of 1300.00 monthly, but only receiving a financial headache.

While driving my 2025 GMC Acadia, the vehicle experienced a sudden and severe failure of the brake master cylinder assembly, causing a significant loss of hydraulic pressure and braking assistance. Multiple dashboard warnings illuminated simultaneously, including ABS and brake system alerts. The brake pedal feel altered abruptly, drastically increasing the required stopping distance and creating an immediate collision hazard. The vehicle is currently grounded at a certified GM dealership awaiting a total replacement of the defective master cylinder assembly under factory warranty. Mileage at the time of failure was 19,000.

I was driving my 2025 GMC Acadia Denali on [XXX] with cruise on. Suddenly sound and banner notifications were telling me that I had no brakes. I immediately hit brake to break cruise and vehicle went faster. I managed to get cruise off from steering wheel. Put flashers on and took foot completely off gas. I was very fortunate that I didn’t hit someone or that no one hit me. After about 2 miles, I was able to pull in an empty church parking lot and get stopped. After getting stopped I was 2.4 miles from [XXX]. I was towed to GMC dealership in Montgomery, AL and diagnosed with defective master cylinder and no brakes. Very concerned because GMC has not issued a recall because the master cylinder failure has occurred many times before.

Since delivery, my 2025 GMC Acadia AT4 has had severe wind noise from the driver's side window at highway speeds. The noise sounds like fingernails on a chalkboard and at times as though the window may shatter. I have taken it to the dealership 4 times with no resolution. I provided video clearly capturing the noise and was still told they could not hear it. I have confirmed the dealer road tests the vehicle in morning traffic at low speeds — where the noise cannot occur. It only happens at highway speeds. Their "cannot duplicate" finding is the result of inadequate testing, not the absence of a defect. After sitting for approximately 7 days, condensation builds up inside the cabin, indicating the driver's side window seal is improperly installed. I reported this to the dealer as well with no fix. After 4 visits, dismissed video evidence, and improper test procedures, the defect remains unrepaired. I request NHTSA investigate this as a potential widespread issue on 2025 GMC Acadia vehicles.

Our onstar module has stopped working since last November after a software update and now issues are starting to cascade causing many other electrical issues to the point that I expect the car to leave my wife and 15 month old daughter stranded. Ours and many other vehicles are having this issue and when any question is asked to gm no response is given or we’re just told to keep waiting.
