The navigation system and the one-pedal driving system started malfunctioning. The navigation system began displaying a different location during remote driving, causing it to send me down a street against traffic. This issue has never been resolved and continues unabated. Then, while on the highway, when I needed to slow down, the one-pedal driving system deactivated, causing me to almost collide with another vehicle. This has happened more than three times this month. GM and Chevrolet just keep saying they'll call me back to resolve the issue, but they never do, and they refuse to fix it.
I was driving my car and a "service high voltage battery" message appeared on the screen and a message to reduce charging the car to 68%. The message coincided with the car having no cabin heat and no ability to defrost the windshield. The dealership says that the cabin heat and AC use the same cooling system as the battery …

The dealership says that the cabin heat and AC use the same cooling system as the battery and that any failure in the battery cooling system can cause a no heat/AC situation

OnStar Module failure. This did not trigger any type of notification. I had to make several phone calls to OnStar to determine I would need to schedule a service appointment for a technician to look at the vehicle. After inspection it was noted that the OnStar Module is not working and will need to be replaced. Upon ordering the part I was informed it is on backorder with no delivery time noted. If I were to get into a crash OnStar would not have triggered a call to first responders for my safety - which is a service that I pay for. No warning lights appeared and the the OnStar button still shows "green" as in active service.

On Monday, April 6th, I was turning into a parking lot and the braking system, specifically the anti-lock braking system (ABS) and electronic brake control module, appeared to malfunction. While driving, I received a warning indicating the ABS was off, and the brake pedal became soft with reduced stopping ability. The check engine light also came on. I had to coast the vehicle to a complete stop. The vehicle is available for inspection upon request. The loss of normal braking function significantly reduced my ability to stop the vehicle safely, increasing the risk of a collision. This created a dangerous situation for myself, passengers, and other drivers on the road. Brake failure at any speed presents a serious safety hazard.I am aware of similar complaints reported for this issue. My vehicle was towed to and inspected by a dealership where it sat overnight before being diagnosed; however, they were unable to reproduce the issue at the time of service. Despite this, the braking failure did occur and remains a safety concern. The service advisor told me to "bring it back if it happens again" and that it "lost communication with the EBCM" which sometimes happens. The vehicle has not yet been inspected by the manufacturer directly, police, or insurance representatives. There were no warning lamps or other symptoms of this problem prior to the failure.
When attempting to engage the Left turn signal, the lever has to be pushed down several times to "catch or engage" and stay engaged. Frequently it won't stay engaged and turns off before the turn is completed. (The Right turn signal works properly). This happens 8 out of 10 times on a consistent basis. The dealer shop supe…

When attempting to engage the Left turn signal, the lever has to be pushed down several times to "catch or engage" and stay engaged. Frequently it won't stay engaged and turns off before the turn is completed. (The Right turn signal works properly). This happens 8 out of 10 times on a consistent basis. The dealer shop supervisor and tech test drove it as well as another brand new lot vehicle and both did the same thing. They said that that's what they all do, and I should push down more firmly, which doesn't help. I'm in my late [XXX] , have driven new GM vehicles for decades and know how to use a turn signal. I have been in the middle of LH turns and the turn signal was not flashing to advise other drivers of my intent to turn. I believe that this is a significant and dangerous safety issue. I bought the vehicle new a little over a year ago and it currently has about 2500 miles on it. I am not sure when this started happening, but I started to notice it at about 1700 miles, 6 months ago when I started driving it regularly in place of my 2024 Chevrolet 1500 pickup.

On four occasions while operating the vehicle down the roadway the dash screen and infotainment / vehicle information displays all have went dark off and reset causing disruption to vital information. Cruise control stayed active. It is unknown if the advanced safety features failed during the reset.
There are two issues with the headlights as it relates to the instrument panel and controls. First, the symbol on the instrument panel is the same for both headlights and running lights. This means at dusk, I cannot know whether my auto-headlights have turned or if I need to override the auto-feature to turn them on manually. …

There are two issues with the headlights as it relates to the instrument panel and controls. First, the symbol on the instrument panel is the same for both headlights and running lights. This means at dusk, I cannot know whether my auto-headlights have turned or if I need to override the auto-feature to turn them on manually. Second, the headlight controls are buried in a menu, hidden behind the steering wheel. The "quick menu" is inconvenient, but the fact that it is hidden bedding the steering wheel means that I have to lean forward and around to fiddle with it, which has led to me drifting into another lane as I am distracted. From the driver's perspective, the "quick menus" are all hidden behind the wheel, and the control panel is just far enough out of reach that the driver must adjust and lean forward to reach for any controls not on the steering column.

1 March, Onstar failed while utilizing the gps late at night. Stuck on side of the road until a passersby assisted me. 2 March, took truck to dealership, after 4 days said no issue found. Driving home, same issue persisted. Called dealership, told to bring back, 45 minutes away. Declined because was told no issue found. 6 March, morning truck completely dead. Called dealership and was told to have towed back to dealership. I declined because you didn’t find any issues when it was there. Following morning, 7 March, had truck towed to local dealership. After a week, was told Onstar telematics module failed and needs to be replaced. As of today, March 29, the part is on back order.
