Received message dash stating "Steering Assist is Reduced, Drive with Care". The AC turned off and temp gauge went to "C". Noticeable difficulty steering at both highway speeds and on city streets. While driving to auto shop the message disappeared, AC turned on and temp went back to normal. About and hour later while diving on the interstate it happened again and steering was difficult again. This first occurred on August 24, then again on September 12 and October 21 and again on October 25. No consistency as for time of day or outside temp. Lasts for a few hours then goes back to normal but when it happens randomly it does pose a safety issue with difficulty steering and no lane assist.

2022 Acadia a bulletin you posted for defective thermostat. My wifeâs car shows exact symptoms but dealership says itâs not included in recall posted by you. Only mentioned car has gremlins? Can you look into expanding your recall since the exact symptoms are as described. By the way I also house a Gm Sierra with a 6.2 and that nightmare continues

What failed & is it available? The infotainment/radio module failed entirely due to an OTA software update (Codes: U18B4, U0184, B1325). The vehicle and component are fully available for inspection upon request. How was safety at risk? The federally mandated backup camera is now too faint/dim to read, destroying rearview visibility. Bluetooth/hands-free phone pairing is completely disabled, increasing driver distraction risks and preventing compliance with hands-free driving laws. Is it confirmed by a dealer? Yes. A local GMC dealership inspected the vehicle and confirmed the module is bricked, quoting $2,286.00 for a hardware replacement. Inspected by manufacturer/others? It has been…

Since we purchased our 2022 Acadia 6/24/2022 we have had the warning "Service Safety Restraint System" pop up randomly. We have mentioned it numerous times over the years when the vehicle has been in for routine service at our local dealership. They have never been able to determine the cause as no service code ever shows up for them. Today in addition to the warning the red air bag warning light also lit up briefly. The warning has popped up 2x in the last 2 weeks again with today being the only time we noticed the red light as well. We are now more concerned about the safety of our vehicle. (We will be on vacation now through 8/25 & would be available after that date for any contact)

âSteering Assist is Reducedâ warning, P0128 code, thermostat-related symptoms, increased steering effort or other safety concerns while driving. This issue required increased steering effort and affected my wife's driving ability to respond to changing traffic conditions. This is most likely a faulty thermostat housing assembly. This has been well documented temperature gauge problems, cooling system issues, and related warning messages. Our GMC Acadia is a 2022 AT4 with 53,500 miles. GM recently issued Special Coverage N252508350 for 2021 Acadias with the 3.6L LGX engine affected by thermostat housing issues. Owners of other model years reporting substantially similar symptoms remain…

This vehicle was bought brand new and has received proper maintenance from one dealership since purchasing. I had to replace the thermostat and radiator before owning the vehicle three years. Within two years of owning the vehicle, my battery went out, which I thought seemed a little early. Then shortly after, I noticed that my locks werenât engaging when I took my car out of park. Then my car wouldnât even lock. When I tried to do it on the door control, nothing happened, then when I used my key to do it, it caused the alarm to go off and I couldnât get it to stop. This resolved after a day, and then it rained again, and it started again. This time, my car wouldnât unlock and I was…
