Automatic Emergency Braking problems of the 2017 GMC Acadia

Thermostat issue (steering assist is reduced drive with care) have changed this sensor 3 times in the past 3 years, there is no excuse for that. The emergency braking almost cause me and my daughter to be hit by a train when my car emergency braked while going over train tracks. This is unexcusable.

Vehicle will apply breaks abruptly on its own whenever it thinks a vehicle is too close. Was in traffic and it kept slamming on the breaks as I would try and move forward. Will slam on the breaks whenever I attempt to just slow down during the course of driving. Was on the highway and anytime I pressed the breaks to slow down, automatic breaks would slam down breaks on its own. Drove vehicle right to dealership as the was a major safety issue for me especially with my baby in the car.

The contact owns a 2017 GMC Acadia. The contact stated while driving approximately 5 mph, the vehicle experienced phantom braking. An unknown warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was 114,590.

The abs system indicated a problem. When I took it into the dealership, they told me the abs was bad and needed to be replaced.

While operating the vehicle I stopped at a red light that was on a hill and the emergency parking automatically came on twice. I could not move the vehicle. It took about 15-20 minutes to finally turn it off. This has happened twice.

Shift to park error code along with several other error codes including no remote detected that have continually and intermittentantly appeared since my car was at 16 k miles. My car has been in the shop over 10 times and these problems continue to return. My car won't shut off correctly, and this drains the battery. On 2 different occasions I was locked inside my car, unable to start it. Both of those times the outside temperature was over 100 degrees, and I almost had to break my window to exit and survive. I frantically pushed several buttons, trying to start the car, and luckily something tripped so I could open my car. The dealership replaced my battery twice before 31 k miles. They have replaced 2 different fobs when the car didn't recognize them. The dealership has replaced the transmission control assembly, the body control module, the fuel injector, the immobolizer control module, the brake control module, and my car has currently been in the shop for over 3 weeks as they may also need to replace the instrument control module and hvac module due to those error codes. My car is at 46 k miles and has been in the shop 3 different times since 39 k (less than 10 k miles) all for similar problems. Thankfully I bought the extended warranty that will expire in 2 years. Something is draining the battery and GMC cannot or will not address the problem. There are similar documented cases: https://lemonlawexperts.

Com/blog/2020/05/GMC-acadia-shift-to-park-class-action-lawsuit-filed-in-texas/ please help to make GMC resolve this complicated problem! I now keep a tool in my car to break a window if I ever get locked in. I also keep my aaa membership active as I have had to get my car jumped several times. I do have videos of the problem, but cannot send a mp4 file.
