2015 Chevrolet Colorado

The 8-speed automatic transmission develops a noticeable shudder or vibration, most commonly felt between 30-50 mph during light throttle application. The shudder originates from the torque converter clutch (TCC) and has been a persistent issue across GM's 8-speed transmissions. Over 150 transmission-related complaints were filed with NHTSA for the 2022 Colorado.

Transmission fluid drain and refill with updated Mobil 1 Synthetic LV ATF HP fluid as recommended in GM Service Bulletin 18-NA-355. GM advises against torque converter replacement alone, as engineering reviews show it does not provide a long-term fix. Complete transmission replacement may be necessary for severe cases.

Certain 2022 Colorado models equipped with a manual passenger seat may have a hook attachment that was not properly welded to the inboard track of the seat frame. The hook can separate from the track, allowing the seat to become improperly anchored and potentially failing to restrain the passenger in a crash.

NHTSA recall issued. Dealers inspect the front passenger seat and replace the cushion frame if the weld is defective. The repair is performed free of charge.

The 2.5L four-cylinder and 3.6L V6 engines can develop misfires that cause rough running, power loss, and check engine lights. Common causes include carbon buildup on intake valves (direct injection engines), failing ignition coils, and fuel injector issues. The 3.6L V6 is particularly susceptible to timing chain stretch at higher mileages.

Replace failed ignition coils and spark plugs. Perform intake valve cleaning (walnut blasting) for carbon buildup on the 3.6L. Inspect and replace fuel injectors if faulty. For timing chain issues on the 3.6L, replace the timing chain, guides, and tensioners.

Owners report electrical system anomalies including intermittent loss of power steering assist, random warning lights, infotainment system reboots, and erratic gauge readings. The electric power steering can fail momentarily, especially during low-speed turns or parking maneuvers, requiring sudden physical effort to steer.

Inspect the electric power steering motor and wiring for faults. Update the steering control module software. Replace the steering column assembly if the electric motor has failed. Check and clean ground connections to resolve erratic electrical behavior.

The HVAC blower motor can fail, resulting in no airflow from the vents regardless of the fan speed setting. The blower motor resistor may also fail, causing the fan to only work on the highest speed setting. This makes the vehicle uncomfortable in extreme weather conditions.

Replace the blower motor and/or blower motor resistor. Inspect the blower motor wiring connector for melting or corrosion, which can indicate a resistor failure causing excessive current draw.

General Motors, LLC (GM) is recalling certain 2015 Chevrolet Colorado and GMC Canyon vehicles. The power steering assist may be lost due to a poor electrical connection within the steering gear assembly.

A loss of power steering, particularly at lower speeds increases the risk of a crash.

General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Colorado vehicles manufactured January 6, 2015, to March 17, 2015, and 2015 GMC Canyon vehicles manufactured January 6, 2015, to March 19, 2015. A poor electrical connection within the steering gear connector may cause a loss of power steering assist.

A loss or reduction in power steering assist may increase the risk of a crash.

GM will notify owners, and dealers will replace the steering gear torque sensor cover assembly, free of charge. The recall began March 1, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 15595.

General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Colorado, and GMC Canyon trucks manufactured January 6, 2014, to December 24, 2014. The affected vehicles may experience the front brake calipers leaking brake fluid. This is due to air pockets, an imperfection in the metal caliper body.

If the vehicle experiences a brake fluid leak it can increase the stopping distance, increasing the risk of a vehicle crash.

GM will notify owners, and dealers will inspect and replace the front-brake calipers if necessary, free of charge. The recall began June 9, 2015. Owners may contact GM customer service at 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14888.

General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Colorado and GMC Canyon trucks manufactured January 6, 2014, to April 1, 2015. In the affected vehicles, the hooks that secure the driver's and/or front passenger's seat frame may not have been properly attached to the vehicle body during assembly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 207, "Seating Systems."

If the seat-frame attachment hooks are not secured properly, the seat may not be adequately anchored to the vehicle, and in the event of a crash, the seat occupant could be at an increased risk of an injury.

GM will notify owners, and dealers will inspect the seats, correcting their installation as necessary, free of charge. The recall began on June 2, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service 1-800-462-8782. GM's number for this recall is 15150.

General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Colorado vehicles manufactured September 15, 2014, to January 21, 2015, and 2015 GMC Canyon vehicles manufactured October 3, 2014, to December 9, 2014. The affected vehicles have a front driver air bag inflator that may be misaligned to the air bag module backplate. This can cause the inflator to separate from the backplate during a deployment.

If the inflator separates from the back plate in the event of a crash necessitating deployment of the driver's frontal air bag, this may cause the air bag or steering wheel components to separate and be propelled into the interior compartment, potentially seriously injuring the driver or other occupants. Additionally, the air bag may fail to properly inflate, increasing the risk of injury to the driver.

GM has notified owners, and dealers will inspect the driver air bag module inflator for proper alignment, replacing the air bag, as necessary, free of charge. The recall began March 19, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 15037.

General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Colorado and GMC Canyon vehicles manufactured January 6, 2014, to October 1, 2014. In the affected vehicles, the driver air bag connections may have been wired incorrectly. This could reverse the deployment sequence and disrupt the deployment timing of the driver air bag. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 208, "Occupant Crash Protection."

If the driver air bag does not deploy as designed, there is an increased risk of driver injury in the event of a crash necessitating air bag deployment.

GM will notify owners, and dealers will reprogram the inflatable restraint sensing and diagnostic module (SDM), free of charge. The recall began on October 6, 2014. Owners may contact GM customer service at 1-800-222-1020 (Chevrolet) or 1-800-462-8782 (GMC). GM's number for this recall is 14690.
