NHTSA complaint #11746241 — an unverified report by a vehicle owner.
My vehicle has 2 issues that are known but only recalled for another year. My car will say shift to park when in park and will not power off. My vin shows no open recalls for this issue for my vehicle but there is a service bulletin for this issue with my year vehicle. The dealer will not cover the cost of repair since my vin is not listed in the recall. Also I just had to replace the vaper cannister purge pump and vaper cannister valve and extended warrenty was offered on the purge pump and valves for 2021 trailblazer for this known issue but not 2022. Dealerships refuse to address my concerns to assist/investigate/return phone calls to help to see how to add the 2022 trailblazer to the recall

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. U0151 – Lost Communication with Airbag Control Module (SRS) The system lost contact with the airbag diagnostic module. This may affect airbag deployment during a crash, making it a serious safety concern.

Month of June of 2024 I purchased 2021 Chevrolet Trailblazer LT with 31k miles on the odometer I had to service my vehicle and had to replace the fuel pump, took weeks to get in due to the strike that took place, Chevrolet will not back behind their employees nor their consumers. They only honored me 15pts on my vehicle, a few months pass and more issues arise one being the manifold sensor (a) and then another two days on the road the wiring harness thankfully my car was under a secondary warranty and I paid $200 per repair, although this became a very costly month being $600 car payment and $400 in repairs in a matter of a few months owning the vehicle, I am having similar issues again with the wiring harness a year later.
NHTSA complaint #11666643 — an unverified report by a vehicle owner.
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.

On [XXX] while driving on the highway my check engine light came on. The car turned off while going 60MPH on the 18 mile stretch towards Miami from Key west and luckily there were no cars around me. I checked for the code and it was P1467 for the Evap Purge Pump. I took it to a dealership in Miami and they told me it would be fine to drive that the part needed to be replaced. I drove back to key west and bought the replacement part. That same part did not work. I checked to see if the part was receiving voltage and it was. So i will continue with going to the dealership. My wife and son have developed a cough from having to constantly smell the fumes due to their existing asthma. I will never buy another chevy again.

IN January my fuel gage stopped working , unable to know how much gas I had. The fuel pump and floater needed to be replaced If fuel was not getting to the engine the vehicle would stop working causing a possible accident with other drivers . I did not use this vehicle for many days until a mechanic cleared for useage . It cost me $320.00 of my own money to fix this for safety concerns. As of today 1/22/25 I has been fixed by A-Plus in North Fort Myers.

I have brought my car into the dealership over the last few years at least 6 times for the same issues. Currently there are two codes coming up as permanent on my car which is for the Evaporative Emission System Flow and Brake Booster Hydraulics performance. I drive my child of three every day and the number of times my check engine light comes on and goes into reduced engine power is not okay nor safe.

05/29/24 I took this vehicle to Cronic Chevrolet in Griffin, Ga due to check engine light being on. Code detected purge pump it was still under warranty at that time only had 43,906 miles on had to get the purge pump replaced. Several weeks after getting it back I kept getting a shift to park message come up when trying to put it in park then started having trouble getting it to go into drive. I have had so many close calls from people almost bashing into me because my car will not go into drive and you constantly have to switch in and out of gears for it to finally go in. Its sucking the had right out due to it not shifting gears properly. The code reader detected transmission control module which I find to be faulty and understand there are serval recalls on this specific vehicle , when it started this issue it didn’t even have 50,000 miles on it!

NHTSA complaint #11585401 — an unverified report by a vehicle owner.
Very strong gas smells coming from under the hood. After driving a few miles, fumes enter the passenger compartment. Had to stop parking it in our garage for fear of a fire before I could get it into the dealer. I've been told it's a fuel leak associated with the fuel rail system. I'm 20 days past my warranty and only at 29,000 miles. It's a nearly $2000 fix. GM was aware of the problem in 2021 as there is a service bulletin for this item. I should have been notified in 2021 that there was a possible problem which could lead to a fire or explosion.
