After programming we also performed the module configuration procedure and although e removed the programming error, the system is still reporting a failure with the LEFT parking brake circuit. All circuits have been checked. The current hypothesis is that the electronic brake control module (EBCM) has failed internally. This likely occurred when the actuator wiring became exposed and allowed the wiring to short together. : https://s3.amazonaws.com/shop-ware-prod-attachments/d0edde862ec36d33b013087e9934f74892154a13.pdf?1678995379

Vehicle warning lights come on randomly - airbags, check engine, ABS. They will light during drive time, then blink out for no apparent reason. Instrument lighting may or may not light when vehicle is started, and instrument console and/or entertainment console will not function when unlit. Again, this happens randomly, and often resolves just as randomly. Have had vehicle inspected by dealer without any issues identified. Issues have been ongoing for a number of years. They can occur without regard to vehicle being in motion.
While driving on very slick roads on a highway, I attempted to brake the vehicle in preparation to making a left hand turn. I could not stop the vehicle. The wheels kept pushing me forward. I could feel the ABS pulsing but the vehicle would not stop. Luckily, no one was ahead of me or I would have hit the vehicle. It felt like the car was overriding my attempts to stop it. I wasn't just sliding on slick roads; the vehicle was actively pushing me forward.
Steering makes a clicking noise when turning the wheel. The vehicle makes a clunking noise when hitting minor bumps in the road and intermittently the steering wheel shakes at highway speeds. The vehicle has a rattling noise when first started and recently the ABS/traction control service light comes on when first started. Also the vehicle has decreased horsepower and the mileage lcd screen has been acting up and not always showing the prndl and also the transmission acts up when shifting into 3 and 6 gear
