On 25 october 2019, while moving forward after backing out of the parking space at my work, the truck began an uncommanded turn to the left. with significant force i was able to straighten the steering wheel. in light of the potential lack of steering control, i had the truck delivered to the courtesy gmc dealership in lafayette, louisiana for repair. according to the repair receipt, the electric belt drive rack and pinion steering gear was replaced and the truck was returned to me on 30 october 2019. on 22 november 2019, again while driving through the parking lot at my work the truck went into an uncommanded left turn. the actions of the truck were nearly identical as i experienced in the first truck loss of control event. i delivered the truck to courtesy gmc in lafayette, louisiana. when the customer service advisor turned the truck into the service bay, a loud metal-to-metal sound was heard from the front of the truck. on 4 december 2019, i met with the customer service advisor and the automotive technician at the courtesy gmc dealership to discuss the status of the truck. the automotive technician stated that he was going to contact gmc about the issue the next morning. on 5 december 2019, i was contacted by the automotive technician who informed me that he had discussed the issue with an engineer at general motors corporation. the engineer advised the automotive technician to replace the part that was previously replaced, but order the part through a different parts warehouse. this was strange to me as i would believe that the parts from any warehouse would be acceptable. on december 2019, the truck repair was completed and was returned to me. thus far, the truck has operated properly.
Steering is intermittent at times. the steering wheel will not turn smoothly, instead it jumps in 1-2" increments. seems to reset or fix itself after the truck is turned off for a little while.
Steering locked when turning into a parking lot and would not straighten out
Power steering would go out at ant time and then it would start working at different times.would have an audible alarm service power steering would come on the display and my abs and brake light would turn on.almost wrecked on 3 different occasions because of the loss and then working of the steering
Making a right hand turn onto our road the steering wheel locked up. i was unable to control the truck other than braking. after slamming on the brakes the steering resumed.
I own a 2017 chevy colorado z71 4x4. once back on the highway after off-roading on the beach, while forward driving at roughly 50 mph i ran over a chopped piece of fire wood in the road. the piece of wood contacted the skid plate, which then collapsed the hollow skid plate bracket welded to the front cross section/axle of the chassis, which then flattened into the plastic power steering module(s) connected to the electric power steering (eps) rack. this caused immediate loss of power steering, loss of abs vehicle control, loss of electrical charge from the alternator to the battery, loss of ability of the vehicle to show correct speed, random transmission shifting (into and out of gears, as well as throwing vehicle into neutral) as well as intermittent loss of all cabin electronics (including tachometer relaying speed and rpms, odometer, fuel gauge, battery voltage gauge, etc.). due to this being a road hazard incident, as well as poor manufacturer design/placement of a plastic electric power steering rack, i was forced to have the vehicle towed and file a claim with my insurance company. repairs have been ongoing for 3 weeks and are still incomplete as the vehicle's computer cannot recognize the new oem part. attached photos show damage with the skid plate removed. mathematical measurements will prove the collapsible bracket, if flattened in a similar directional manner, will most definitely make contact with and impact the electric power steering rack. this plastic rack also includes other modules that impact the aforementioned performance issues. gm has failed to acknowledge my concern of design after multiple attempts and conact with their
Tl* the contact owns a 2017 chevrolet colorado. while driving low speeds, the steering wheel became difficult to turn. the contact had to jerk the steering wheel to get it to operate normally. in addition, the brake warning indicator illuminated. the "please check power steering "and "drive safely" messages were also displayed. the vehicle was taken to barley automotive (791 ste genevieve dr, genevieve, mo 63670, (573) 355-9633) where it was determined that the vehicle was operating as designed. the vehicle was not diagnosed or repaired. the manufacturer was not contacted. the failure mileage was 19,000.
