ELECTRICAL SYSTEM
After heavy rain or a carwash, the door locks and lift gate don't work from key fob. And the vehicle says no remote detected and has trouble starting. After a day or two they start working again. It caused U0422 (invalid data received from body control module). On forums it says it can be water leaking into the vehicle and shorting out the BMC from either the HVAC drain or a weatherstrip somewhere. Now my rear passenger door locks don't work at all. Dealer wants to replace the actuators but can't find the root cause of the problem. Issue has been going on for over a year now.

Started getting a warning indication when starting the vehicle that stated some portion of driver assist was not functioning (or some verbiage close to that). We didn't notice any difference in the operation of the vehicle and took it to a service shop after about a week. They did some testing and discovered the problem. I am not mechanical at all but they said there were several technical bulletins from the manufacturer that led them to the problem - a bent pin on one of the rocker arms. I am going to upload the technical bulletins (3) they provided me as well as the invoice (3 pages).

The Car has over the last few years not turn off due to shift to park. This is concerning, due to we cannot turn the car off unless we strike the shifter few times assuming this is the remedy. It doesn't look like there is any type of recall but there should be.

Car will not shift into park therefore I cannot turn the car off without disconnecting the battery. Dangerous bc you don’t know if the car is in park or not when you have to get out and stand in front of car to life hood and disconnect battery.

SERVICE BRAKES, ELECTRICAL SYSTEM, EXTERIOR LIGHTING
I experienced the brakes squeaking on and off for a few weeks this past summer. When at the dealership for an oil change, I was told the brakes pads were still good and the squeaking is common, especially during hot humid weather. Since then, I have lost the brakes twice. Both times, the pedal went all the way to the floor without resistance and after a few seconds, they came back like nothing happened. There was no warning at all. I have also experienced a complete blackout on my dashboard for about 30 minutes without known reason. On a separate occasion, the battery died for no reason. There have been times that a message is displayed on the dash to service rear turn signal lights. They flash fast as if they were out, then the next time I drive the car, they are completely normal. From what has been reported, there are some serious concerns with the 2024 Acadia. I have leased 3 Acadia's before this one and have never experienced anything like this. The brakes failing completely could have ended very badly for myself and/or others. There are several other reports of this nature. Please look into recalling this vehicle to prevent fatalities!!

ELECTRICAL SYSTEM, SERVICE BRAKES, ENGINE
purchased the vehicle in good faith, unaware that the check engine light was illuminated at the time of purchase and not informed that this indicated a serious mechanical or emissions-related issue. After purchase, the dealership repaired an emissions-related problem, and the check engine light was no longer present when the vehicle was returned to me. However, within three days of having the vehicle back in my possession, I began experiencing additional issues, including electrical malfunctions and abnormal noises coming from the front wheels. These problems caused the vehicle to feel unsafe to operate and raised serious concerns about its reliability and overall safety. Due to these concerns, I returned the vehicle to the dealership immediately.

VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
The electronic dashboard goes black while driving. I was driving to work on the highway at highway speeds and the entire electronic dashboard went black including the hud display and the radio screen. The radio screen turned back on and auto reconnected to my phone and android auto. I was able to safely get to an exit and park, turn off the car and restart and the dash did come back on to then go black about 5 minutes later this time the hud stayed on and I was able to get to work where the car sat off for 8 hrs , when leaving work the dash stayed on. The radio screen would turn off randomly and unable to connect to a programmed cell phone via Bluetooth or data cable. I brought the vehicle in for a service and this issue plus the concern of the transmission shuddering. The dealership found the problem and both the dashboard and radio needed service updates and both were charged to fix. A service update should not be charged for the dash as you have no speedometer when it goes out. There was no warning or alert that the dash or radio needed an update.
