2023 Chevrolet Traverse Electrical System Problems

Driving down the interstate the main screen went out completely, GPS, radio, controls to temperature for the back. Back up camera works and it shows a Chevy sign. GM dealer states the radio/Onstar module is out completely. This ironically happened immediately after warranty expired.

The contact owns a 2023 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle unintendedly shut off, the instrument panel went black, and the vehicle lost motive power, and the vehicle lost power steering and power brakes functionality. The vehicle was shifted to neutral(N) and restarted, and regained power, and the vehicle returned to normal functionality. The failure also occurred while depressing the brake pedal. There were no warning lights illuminated. The failure had become more frequent and occurred approximately 3 - 4 times a day. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 20,000.

I have read several things about EBCM and the control power circuit being above threshold and wondering if this is a recall for this model? I am getting 3 error codes C0800, B1325, & U0151 for this vehicle. (General Motors is recalling over 449,000 SUVs and pickups (2023–2024 Cadillac Escalade, Chevy Suburban/Tahoe, GMC Yukon, and select Silverado/Sierra 1500) due to a software fault in the Electronic Brake Control Module (EBCM) . This issue prevents the brake warning light from illuminating if brake fluid drops, increasing crash risk.) It's showing the same issues as above.

The infotainment center went black. No sound in vehicle, no back up camera, no radio

Radio screen went black and back up camera not working. no chimes or turn signal not making sound

I was driving and the vehicle lost since power, I was unable to roll down the windows. And then the car just stalled. Luckily I was aware of it stalling so I pulled over in a residential area and came aaa. They sent out a battery service technician, he read the battery, the battery was ok but the alternator had low voltage. (Picture attached) so they recommend not to drive it and so I had to call for a tow truck to come. We bought a battery charger, it charges up to 12 but when we put it into drive it drops back down to 10 and that's when everything shuts off and the car dies.

The contact owns a 2023 Chevrolet Traverse. The contact stated that while driving 50 MPH, the vehicle inadvertently lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle failed to restart. The battery warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the alternator. The vehicle was not repaired due to parts being on backorder. The manufacturer was not notified of the failure. The failure mileage was 45,000.

While practicing parallel parking in the vehicle for about 1 hour, upon leaving the parking lot, there was a message that popped up on the dashboard reading, “SERVICE BRAKE ASSIST”. When driving the vehicle out the parking lot, the brakes were hard when pressing and the vehicle took a while to brake. I found myself braking at a far distance in order to stop the car at the nearest stop light. I turned my emergency lights and drove carefully home, since the engine light came on, which I parked and turned off the car. The next day, I turn on the vehicle and the engine light is still on, I take it to the local Auto Zone for a code, code P0556 is showing BRAKE BOOSTER PRESSURE SENSOR. I then call the dealership, they tow the vehicle and upon arrival they run diagnostics and text me the following message: “ Buckalew Chevrolet: They looked into all of those. They'd have been induced by the parking brake situation, however eveything in the computers have moved to "history" standing which means the vehicle no longer deems it an issue. If a code is not active or current, there is not much I can do with it. It shows us what the computer saw as having an issue, but not what the issue is or how it occured. Without us being able to duplicate it or it actively giving a signal that we can measure, we are kind of stuck without a paddle.” They next say they don’t find anything and they cannot fix it, there I have to go pick up my vehicle. Therefore I do, but the following weekend I go practice parallel parking AGAIN, and the issue happens all over again with the EMERGENCY BRAKE ASSIST turning on by itself, I continue to have braking problems. “STEERING ASSIST IS REDUCED DRIVE WITH CARE” reads on the dashboard, I call the dealership, they say I have to bring the vehicle in when it’s actively having the issue, and I explain that once I turned off the car, the dashboard message disappeared. No response, no resolution. the dealership just brushed it off and said it was nothing.

The contact own a 2023 Chevrolet Traverse. The contact stated while the vehicle was turned off and parked in the garage, the exterior and interior lights started flashing, the horn started honking continuously, and the windshield wipers activated. Additionally, the doors locked and unlocked inadvertently and stopped when the vehicle was in drive(D). The vehicle was taken to the dealer where it was diagnosed that the computer module needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 17.

After purchasing our vehicle we noticed back up camera view was switch to a globe view and noise in vehicle when driving over 40 mph that sound like electric wires shorting. Took to dealership they said they did updates to information center. After a few days it continued to do the same issues. Called dealership back and they took another look at it and said they once again pushed out a large update. Well vehicle continued to have same issues with addition of now rear view camera is going while in drive. Stereo screen gets all glitched up. Took it back and they kept it for a week and claimed they replaced stereo next day after picking it up it continues to have same issues and now my apple CarPlay doesn’t work. They claim I need WiFi to have it connected. Which is a lie it was working before they replaced stereo. I have contacted GM regarding all this. There is an open case. We have only had our traverse for 3 months. I have videos as well that my children have taken while reverse camera is going while I’m driving in drive.

On April 17, 2023 I was on my way home from work and got a message " Battery Saver Mode Activated." I checked the voltage and it was at 11.4. By the time I got home, the voltage had gone down to 10.3. I took the vehicle to the dealership on April 19, 2022 for repair. It was a bad alternator. On June 29, 2023, my family and I were on vacation and at a hotel in North Little Rock, Arkansas. I got up the next morning, 0330, and started the car and I got a message, " Battery Saver Mode Activated." I checked the voltage. It was at 11.3. I had to drive to the nearest truck stop so we would not be stranded on the side of a dark highway. The battery light came on and a message came up something like, "Charging system low. Vehicle could stall anytime." The battery light remained on. We made it to the truck stop, voltage was at 10.1, and I had to call a tow service to take my vehicle and my family to the nearest dealership in Stuttgart, Arkansas. It was another bad alternator and was repaired again and returned to me on August 4, 2023. Both instances, I was on busy highways with no gas stations for miles and not very good cell service. I live in Texas and the weather was hot and I had my son, my granddaughter, and 3 dogs with me. I couldn't get the windows down because the battery was dead. I contacted the manufacture. The vehicle is available for inspection upon request and has not been inspected by the manufacture as of yet.

After owning new vehicle for one month the check engine light comes on, return to dealer for service and we are told there is a known issue with 2023 Traverse showing check engine light off the lot. The vehicle is inspected and found that wires from the computer are rubbing/melting against a hot surface in the engine/transmission causing a faulty check engine light.
