2024 Chevrolet Colorado

At ~20,300 miles, severe chassis and steering wheel vibration occurred during high-speed highway descents while braking. Safety risk: reduced steering control at highway speed. The vehicle was inspected by a franchised Chevrolet dealer in Lakewood, CO. The technician's written service notes document rear rotor Lateral Runout (LRO) of 0.006 inches against GM's maximum allowable specification of 0.002 inches per GM Service Bulletin 00-05-22-002 — 3x the engineering limit. The defect was confirmed in dealer documentation and is available for inspection. After I identified this discrepancy, the Service Manager claimed the technician meant 0.006 mm (metric). Photographic evidence from the dealer's own diagnostic video shows a dial indicator clearly labeled in 0.001-inch increments with the needle resting on the 6th tick mark. A metric reading of 0.0002 inches is physically impossible to display as 6 full divisions on this tool. GM Customer Assistance denied the warranty claim, classifying it as maintenance. Lateral Runout is a geometric specification, not a wear measurement. A rotor 3x out of tolerance at 20,300 miles is a material or assembly defect. No warning lamps appeared. The safety concern remains unresolved.

The contact owns a 2024 Chevrolet Colorado. The contact stated that while driving at various speeds, the steering wheel was stiff and difficult to turn in either direction. In addition, the passenger’s side mirror failed to illuminate while another vehicle was passing by as intended. The messages "Reduced Acceleration", "Service Steering", and "Service Drive Train" were displayed on the instrument panel. The ESC warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed; however, the cause of the failure was not yet determined. The contact stated that while driving at various speeds, the vehicle lost automotive power. The vehicle was not repaired, and the failure became progressively worse. The manufacturer was made aware of the failure. The failure mileage was approximately 3,000.

Steering Column cover was rattling and felt coming apart. When Right side Turn signal was activated and the turn was completed, automatically left side turn signal was activated. Both of the above concerns were addressed by the GM Chevrolet authorized dealer on 8/26/2024. Again the Turn signal started malfunctioning as stated above, and the vehicle is now at the same GM authorized dealer for service with additional AC compressor failure. Date: 5/28/2025.

1.) While driving signalling for a right hand turn and then subsequently completing the right hand turn, the vehicle then signals left on its own accord. This is distracting for the driver and confusing to other motorists on the road. 2.) Blind spot monitoring system frequently turns on and or blinks rapidly (effects both driver and passenger side mirrors sporadically) when no other vehicles in the same vicinity. Distracting to driver who then is prompted to look around for vehicles that are not there. Quite often the trucks blind spot monitors light up when not a single other vehicle is on the road anywhere. This takes place on full size two lane roads and wide open multi lane highways where there are no objects near the vehicle whatsoever.

The turn signals to not function correctly and give inaccurate signals to other drivers. Most (perhaps all) times, when signaling a right turn, after the right turn signal deactivates, the switch "overcorrects" and signals a left lane change (three blinks to the left). This no doubt leads to confusion to other drivers and could cause a accident. Turn signal must work flawlessly! This problem has been broadly reported on the Chevy Colorado internet forum.

After completing a right turn with a right turn signal, the vehicle will sometimes signal a left turn for 3 blinks. I believe this is because the turn signal stalk 'bounces' down to the left turn signal area when returning back to normal position from a right turn.​ ​ This is a safety issue because the vehicle is signaling a left turn when no turn is intended. This could cause confusion to other drivers on the road.​
