Answer Question
2023 Chevrolet Trailblazer RS service ECM , service Power Steering warnings on display
Recently had an accident on LH front of vehicle where the steering knuckle sheared in half. Got it back from body shop (after 4.5 months) now have a service ECM and Power Steering message on the display (where the digital speedometer shows). Body shop states that they took it to the dealer and had the codes cleared but they showed up again and they (body shop) are unable to figure it out, so they gave the car back to us as it was. Traction control, Auto Stop, Lane assist are not working. Could this be a speed sensor failure on the LH steering assembly, transmission sensor or steering column position sensor? The transmission is also acting weird as you have to rev the engine about 500 RPM over the idle speed for it to engage. Vehicle also pulls to the right very hard which could be a bad front end alignment. Any help would be much appreciated.
