What owners report
My 2023 Chevrolet Trailblazer is about 3 months old and it's been making squeaky noises when I break. The squeaky sound is getting worse over time and I have an appointment scheduled with Chevrolet to get this resolved. My concern is a 2022 recall on this same vehicle due to the break system. Therefore, I am reporting this for the year or 2023 because my car is brand new and making screech noises every time I break. Also, my electric system randomly stops working. For example, my touch screen Car play system pixelates and sometimes doesn't even work. I turned off my car and the radio stayed on and the volume wasn't going down. The car was off and the radio was still playing! After about 15 mins the radio stopped playing while the car was off. Something isn't right with my trailblazer, electric and breaks. …
The ABS system in this vehicle flashes warnings at quick restarts and while holding the brake down, it has no "sponge" when this happens. The brakes squeal constantly. I've had them inspected at every single maintenance and there can be no flaw found. When driving on the interstate, the engine is very "jerky" almost like the transmission can't keep up with the speed of 70-80mph (not always, but it is noticeable when it happens). At first I didn't think much of it but with the mass recall of chevys identified, I believe it needs to go on record - particularly about the brakes.

Vehicle Diagnostic Summary - Trouble Codes Explained 1. P0562 - System Voltage Low The vehicle's electrical system is running at low voltage. This could be due to a weak battery, a failing alternator, or poor electrical connections. It may cause various electronic issues and unexpected shutdowns if not fixed. 2. P1005 - Fuel Level Sensor Control Module: Too Many Resets The fuel level sensor module has been reset too many times, likely due to electrical glitches. This may cause the fuel gauge to be inaccurate or unstable. 3. P14C0 / P14CD - Fuel Pump Driver Control Module Signal Error There is a configuration signal error from the fuel pump control module. This could lead to fuel delivery problems, starting issues, or engine stalling if it worsens. 4.

The fuel gauge is fluctuating from full to empty and the empty light comes on. It has occurred a few times now over the last few weeks. The issue has the potential to cause a stall condition, if the vehicle runs out of gas unknowingly due to this inaccurate gauge condition. I have been able to research some documented evidence of this known issue on NHTSA, but have not found any solution being offered by GM.
