General Motors has issued a Technical Service Bulletin to address problems with the driver information cluster display on certain 2020 model year GMC Acadia and Chevy Malibu vehicles.
The TSB (N202309750) indicates that 2020 model year GMC Acadia and Chevy Malibu units equipped with the optional eight-inch Diagonal Multi-Color Driver Information Center (RPO UHS) may change the radio station/audio track without customer input. In response, dealers will reprogram the instrument cluster, the automaker said, which will remedy this issue.
The eight-inch UHS Diagonal Multi-Color Driver Information Center is an optional, full digital driver’s display that is available in certain GM vehicles, including the 2020 model year Acadia and Malibu. The configurable, full color display incorporates the speedometer and tachometer and can also display warning messages and other vehicle information such as estimated mileage or oil life, for example. In the GMC Acadia, the display is only offered on the Denali trim level, where it comes standard. Similarly, the only way to get the full color cluster display in the 2020 Chevrolet Malibu is to opt for the range-topping Premier trim.
GM has had similar bugs with other in-vehicle display screens in recent months, as well. The automaker issued a fix over a bug pertaining to the favorites menu in certain Buick, Cadillac and GMC vehicles last November and is also facing a class-action lawsuit over alleged problems with the IOR 7-inch radio in certain 2019 and 2020 model year vehicles. While not related to software, the automaker was also sued last year after customers complained the CUE infotainment screens in some Cadillac vehicles were prone to cracking.
Newer GM vehicles running the automaker’s Global B electric architecture can take advantage of over-the-air updates to address potential infotainment bugs such as this. Neither the Acadia or Malibu run off of Global B, however, so customers affected by this issue will have to bring their vehicles into a dealership to have them repaired.

Gmc. Needs to fix the issues with the power reduce engine that pops on when you are driving which slows down your driving speed. This is very dangerous especially driving on the highway. Its going to be a lot of lawsuits coming because gmc wont do a recall on the Chevy Malibu 2016.
My 09 Acadia does the same thing, like something automatically reduces my speed. Along with other consistent Acadia issues. I take darn good care of my vehicle. Upsetting! Beautiful truck, too many problems. Certain issues should be recalled, that never was.
My 2012 acadia denali does the same thing traction control engine power reduce.
So many time i took it to the dealer and it still happen.
Our 2017 Acadia screen pushes its own buttons and has dead spots. The dealer said it needs a new screen. It’s really frustrating and feels like something the manufacturer should take responsibility to fix.
Did you find a resolution to this? Our 2019 Acadia screen just starting pushing buttons, making calls and doing things on its own
Did you try cleaning the screen with one of the special electronic wipes? That worked for me for about a month, then i cleaned it again when it started acting up again. The dealer said I needed a new screen, but so far this seems to be working.
I have taken my 2018 Malibu back to dealership again for same problem: Low fuel, steering assist, shift to park, engine icon stabiltrack lights come on as well as the dials go to zero. Shift to park comes on even when it’s in park. No lights on steering column or dash to let you know what gear it’s in. A little over 13000 miles. I had to get it towed Monday to Greenway in Tuscumbia Alabama (where we bought it)because it wouldn’t turn off or turn on. Had to put emergency brake on because I had no brakes. They said battery needed to be charged & there was a recall. Picked it Tuesday-fine. Wednesday lights again, loss of power, brakes smell like I was driving with them on. I’ve taken this car back to have it fixed several times and this keeps happening. This is ridiculous! In the other forum government? this has been happening with other years of Malibu. We have no other car. And dealership had no loner. I work 2nd shift and it’s really scary knowing you could be stuck on the side of the road.
You highlight some great ideas-but I am concerned you may be generalizing. I want to see you write more about this, because you are a very eloquent writer and I enjoy reading your posts.
Is anyone here in a position to recommend Shapewear? Thanks x
