2024 CHEVROLET TRAILBLAZER Electrical System Problems

My 2024 Chevrolet Trailblazer has two main issues. First, there is a constant squealing noise when braking. I reported this twice to the dealer — the first time they said it was just sand inside the wheel. The noise continued. On the second visit, they told me it would cost over $100 to inspect the brakes because the wheel needed to be removed, which I couldn’t afford. This problem started before the vehicle reached 36,000 miles. Second, the electrical system malfunctions occasionally while driving. When I connect my son’s phone to Bluetooth, both the dashboard and infotainment screens shut off completely for a few seconds. This happens while the vehicle is in motion, and it is extremely dangerous, especially on highways. The screens then turn back on. I believe both issues may relate to safety and should be investigated.

The dash and radio have gone out while driving several times now. Was driving out of state on vacation and it has gone out on us over 9 times. We will be driving and the dash goes black. You can’t see your speed, gas or radio.

The vehicle was started with the key fob. The vehicle was then driven for 12 miles without a key within the vehicle. I had to bring the key to where the vehicle was located to lock the car and be able to drive it. This has not been inspected.

THIS IS AN UPDATE FOR COMPLAINT # 11619009 After doing some online research and discussing with the service manager at my dealership, we identified a SIMPLE issue- apparently there was a problem with the torque used in connecting the ground wire for the electrical auto start-stop feature, which is what cause my vehicle to completely die and not be able to be restarted. after it was identified, it was corrected within minutes. I highly recommend that there be a service bulletin for any purchasers/lessees of the new 2024 Trailblazer (and possibly other Chevy vehicles) to have the grounding issue checked.

I am writing to formally express my frustration and disappointment regarding ongoing issues with my vehicle, which I purchased new on [XXX]. Despite repeated efforts to address these concerns with authorized dealers, I have been unable to achieve a resolution. My vehicle currently has 13,630 miles and remains under warranty. However, I feel my concerns are not being taken seriously, and the vehicle's persistent issues are being overlooked or dismissed. Background of the Issue: For over a month, I have been reporting significant electrical problems and other malfunctions with my vehicle. Each authorized dealer I approached assured me that nothing was wrong. To verify these claims, I sought a third-party diagnostic evaluation, which revealed two specific error codes—clear evidence of underlying issues. Details of Dealer Appointments: Appointment: November 25-26, 2024 I entrusted my vehicle to [Dealer Name], where it was kept for two days. Despite this, no diagnostic efforts or repairs were conducted, as confirmed by the service advisor, Erica Jones. Frustrated by the lack of action, I retrieved my vehicle on November 26, 2024. Second Appointment: December 2, 2024: I scheduled another appointment with the same dealer and dropped off my vehicle on December 1, 2024. To my dismay, the paperwork I received at the conclusion of this visit contained several discrepancies: The entry date was listed as November 25, 2024, with a promised completion date of December 2, 2024. This is incorrect, as I had my vehicle from November 26 to December 1, 2024. The mileage recorded at drop-off was less than the actual mileage on the vehicle at that time. The report stated that only one mile was driven during the diagnostic process, which is insufficient for evaluating my concerns thoroughly. Issues Reported: I have consistently reported the following problems with my vehicle: Seatbelt Malfunction: The seatbelts fail to secure me during sudden braking situations,etc...

My daughter was stopped at a stoplight and the auto-stop engaged. The light turned green and she began to accelerate when all of the error lights on the dash lit up, then the dash info system and infotainment system went out followed by the engine turning off and not restarting. While all of this happened, the vehicle behind me struck my daughter’s car. Luckily it was at a low rate of speed and no one was injured. I took the car to the dealer and after nearly a week of testing they found nothing wrong and found no error codes in the system. They ere not able to replicate the problem. However, once we got the vehicle back a similar instance happed again, except just the dash info system and infotainment system went out and the car was still drivable. Once restarted the electronics came back on as normal. It has not happened again at this point. Had the first incident happened at a higher rate of speed a severe injury or fatality could have occurred.

I was driving my 1 week old vehicle, on a city street, foot still on the gas, and the vehicle COMPLETELY shut down; no power at all. it wasn't the auto start/stop technology, but rather a complete power down. no lights, no hazard lights, no dash, nothing worked. The car came to an abrupt stop. The gear shift could not be moved into neutral, nothing. Luckily I was on a city street with not a lot of traffic. If I had been on a highway it could have caused a SERIOUS accident; if I had been driving across railroad tracks and it stops - very dangerous. I was able to contact AAA, and after a "jump", it started. However, because of my proximity to the highway, I opted to have it towed to the dealer where I bought it....they ran service on it and can find nothing wrong with it...as you can imagine, I am nervous to drive on the highway (which I do 5 days a week normally)...

I was driving and the vehicle cluster display and radio went out. I was unable to see how fast i was going and any system info. It eventually came back on. During this time the car was continuing to drive but unable to see any lane - blindspot warning or speed or system controls or warning events.
