2021 GMC Acadia

While driving vehicle stalled multiple times in the middle of the road, with service transmission and engine light coming on, causing unsafe conditions, causing accident and leaving passengers stranded. Battery being drained and needing to be replaced multiple times within 2 years. Vehicle stopping and shutting off on the highway causing dangerous driving conditions!! Radio and lights flickering, with radio freezing and shutting off. Electrical system not working properly and overheating!

While driving down the interstate at 70mph+, the instrument panel went black and restarted multiple times. The car continued to stay at a sustained speed, but I was unable to control anything or see how fast I was going. It appears as if the car has shut off, but it isn't. It also affects the lights. It has happened multiple times with no known cause. When I brought this up at the dealership, they said that it would be an $80 diagnostic fee and unless they can replicate the problem they can't do anything about it because it doesn't throw any error codes. There was another women in the dealership the same time as me with the exact same issue. No fix offered. Looking online and talking to others this seems like a common issue that GMC is ignoring.

Electronic dashboard failure. Entire instrument panel randomly shuts off while driving, including speedometer and all gauges. Driver then has to wait for system to reboot itself before it begins working again. This condition is completely random and may not occur for months, or may occur several times within minutes. This is a safety issue due to the driver's inability to monitor speed. It is also possible that other safety systems are being shut down while waiting for the system to reboot. GM has known about this software glitch since 2021, and it affects certain GM vehicle models from 2021-2023. (Refer to GM TSB# 21-NA-054). NHTSA should require a recall for this problem.

My 2021 Acadia digital dash goes out (completely black). I took it to the dealership on Friday August 25, as the issue was happening more frequently. I was told the software was not current. This was attributed to parking in a garage each night. Yesterday September 22 while driving, the dash again went out for a much longer timeframe (several miles). I called the dealership. Service was closing but was told by the receptionist that one of the sale people said to (1) park the car, (2) turn off the engine, (3) open the drivers door and leave open for 5 minutes to reset the system and everything should be fine. The black dash prevents the driver from seeing current MPH. I am uncertain if it also disengages adaptive cruise control and auto-braking. Is it acceptable for the digital dash to routinely go black while being operated? Is there a more sustainable resolution for the dash going out? Thank you!

The IPC goes out while driving. GM is aware of this issue in several models they make starting in 2020. They failed to call a recall on the issue and when you take it in to be looked at there is a service bulletin out to have the dealership to do a software update on the IPC to resolve the issues that some customers may be experiencing. This issue costs 189.99 to diagnose the first hour then the dealership spends another 2.5 hours diagnosing the known issue to charge customers for a total of 3.5 hours in repair costs. GM does not assist in anyway with covering the cost of the repair to the vehicle that is a 2021 make and model. In all to make your car safe to drive again the repair costs 474.88 and there is no guarantee after the software is updated that the issue will not come back and then I will be left with taking it back in for troubleshooting to be charged another 474.88 as long as the price does go up for electrical diagnostics charges. It’s pretty convenient on GM and their dealerships to charge customers a to fix a safety concern that can happen again and charge 3.5 hours of labor charged even when there is a service bulletin out telling repair technicians to do the software update when a customer stated the IPC goes out while driving and comes back on. If there is a know. Issue then my issue should be been resolved with just having to pay for time it took the repair technician to do the software update. Not waste time tracing all wiring just to run up all labor rates first.

Vehicle has previously been brought in to GMC dealership at least 2-3 times for the dash turning on and off while driving. Started happening around 5,000 miles here and there. First took it in just over 7,000 miles as it was happening more and more frequently. It was last in for the issue on 2/6/23. The dash turned completely off WHILE driving going approx 45-50 mph, is not turning back on, unable to see speed while driving.
