2021 CHEVROLET SILVERADO 1500 Complaints

When I put the pickup in park, I get a message that states "Shift to Park". The pickup is completely stopped, the gear shift indicator is in "P". When I get out of the vehicle I get two loud two-horn alerts indicating that the pickup in not in Park, when in fact it is. Doing some research, I have seen that this is a common problem for GM vehicles. The console shift vehicles are actually involved in a class action lawsuit, while the steering column shift vehicles are not.

Check engine for cam shaft sensor wiring harness burnt up and damaged in numerous places shows bulletin board for this issue online but no recall has been made for this safety issue

Vehicle bucks upon acceleration in the rear end. Dealer recommends replacing the transmission.

Currently had my engine go into "limp mode" after checked engine light came on with code p1010. The coolant control valve is what is the problem, and GM/Chevy has issued a special coverage on this known part for my year make and model (Bulletin N252508341). However, according to the dealership, my VIN does not qualify for this known issue, regardless of my faulty part matching the special coverage for the year make and model of my vehicle. Now I'm stuck paying for the empty promise from Chevy.

The paint is coming off of the roof of my 2021 Chevrolet Silverado pick up truck. This is a common problem with the white color vehicles from Chevrolet. This is a safety issue due to paint chips and paint pieces falling down on the windshield.

The key will not release from the ignition when in park. This is all over the internet as a very big problem. People are bypassing the ignition interlock so they don’t have to leave the vehicle unattended with the key in the ignition inviting theft. Therefore while driving the ignition could be cut off and the key can come out. This is a huge safety issue. This will kill people.

On August 22, 2025 the malfunction indicator lamp (code: P146B Evap. purge pump) illuminated with no noticeable change. Ran codes at auto zone which stated engine failed and emissions not ready. August 25, 2025 drove to certified Chevy dealer dropped off vehicle and showed the service advisor the fix finder test results from auto zone as well as the illuminated indicator lamp (check engine light). August 26, 2025 picked up my vehicle with receipt stating "found dtc's P146b and P1467 stored in ECM (engine control module) for evap purge pump fault. inspected evap canister for any signs of fuel and none were found. replaced evap purge pump per special policy #N232395310. Cleared dtc and road tested vehicle to verify repair". September 9, 2025 my engine indicator light illuminated and my engine entered limp mode, a safety feature which reduces cylinder output/capacity. September 12, 2025 while in limp mode, I returned to the service dealer and informed them of the reduced power (limp mode) and my confusion as the second engine symbol that has been illuminated is in a different area than the first and my truck has ONE engine. (editor note: malfunction indicator lamp is for the emissions). My original transmission (8L90) was replace, because my vehicle was under power train warranty and the service advisor took it upon himself to approve the disassembly of my running, in good condition 8L90 transmission without consulting me or my approval. the 8L90 was "discontinued" for the 2020-2022 years without recall come to find out (sarcasm). I now have a new transmission (8L86-85) with the "special coverage" part (#N232395310) still connected, only now I have NO additional powertrain coverage for a new transmission, but the "special coverage" originally issued in 2023, BY MAIL, for 15 yr/150,000miles has extended two years plus mileage. (15 yr / 152,955) .The "special coverage" part should NOT affect the engine! Engines produce power/HEAT not CO2 . Sarbane - Oxley Act.
