In March of 2022 the vehicle displayed a warning to service the side detection system. on March 31st 2022 the dealership diagnosed that the Side Blind Zone Alert Module failed due to water intrusion. The replacement of the modular was completed free of charge under "Campaign - N172097060 Special Coverage Adjustment". In December of 2024 the same warning to service the side detection system was activated again, several weeks later the warning lights on the side view mirrors lite up and remained on. Upon bringing the vehicle on February 13th 2025 for service, in it was determined to be caused by the same failed part as the first occurrence. This time the repair was not covered by the dealer, and was 1099.22. GMC has not solved the underlining problem with these parts. The side detection system is critical when driving a larger SUV for blind zone awareness to avoid collisions while driving in multi lane traffic. When the system failed, the lights on the side view mirrors made driving difficult due to the distraction and glare. Although this problem is known by the manufacture it has provided a permanent solution, as they continue to use the flawed original parts. Due to the sensor being electrical, there was no symptoms prior to failure; the warning appears and continued at each start up. The cost of repairing safety features on an ageing vehicle becomes a burden, especially when those features can only be repaired by a dealership at high prices. This keeps many people from maintaining or fixing their cars, putting others at risk. I have the modular from the most recent repair, and will include a photo if possible.

I was driving and all of a sudden my drivers seat started to move foward and down and then eventually reclined fully back and then stopped. Now my seat is permanently reclined. I could have been killed or seriously injured because the seat was moving while I was driving the car and I felt I could have been smushed into the steering wheel.

Special Coverage Adjustment N172097060 Side Blind Zone Alert Module Water Intrusion was issued for my vehicle. I took it in to get fixed and was told I was past the 6 year extension (May 2022) but under the milage (79,199). They told me the parts are on back order from GMC. This was on 04-03-2023. On 04-05-2023 I was driving my vehicle and the instrument cluster went partially blank. I lost my speedometer , tachometer and most of the other gauges. I had numerous warning lights on. The blinkers stopped working and I had no control of any environmental controls or radio functions. I pulled off the side of the road and shut the vehicle off. I tried to restart it, it started but even more things began to fail electrically. I shut if off again, tried another restart and now it would not start. I tried multiple times and could not get it to start. With the car off and the key out of the ignition, the heater control panel would stay on and the fan was running. I tried a few more times and finally got it to run but still had no instrumentation. I was less than a mile from home and tried to make it back. While driving I had no electrical control of anything and no way to determine my speed. I made it back, but now my vehicle will not start at all. With the key out it still runs the heater controls and fan. This is a dangerous situation not being able to control your vehicle electrical systems and being able to start your vehicle. This needs to be a recall, NOT a manufacture " Special coverage adjustment" that they know is a known issue and dont even have to parts to fix it.

I was unable to see the road, my speed, or anything within the vehicle. I did some research and this is a vary common issue with these vehicles and nothing has been done to correct it.

Passenger side carpeting and foam are soaked from a leakage somewhere. The fuse panel under glove box is soaked and not working correctly. Water is almost making its way into battery under passenger side rear floor. Rust has formed under the shifting console. Car is moldy. No one can tell me what is happening but thousands of complaints online regarding GMC Acadia all have this problem. My vehicle is useless 20,000 in the driveway and cannot drive. Not to mention me and my kids have been driving in mold for who knows how long. GMC needs to fix this issue before they have a class action lawsuit on their hands.
