NHTSA Complaint #11461638 — 2016 KIA SORENTO

A couple of months ago, we parked the Kia in the garage and the next morning, went to start the vehicle and attempted to put it in gear and the shifter button would move depress. We ended up replacing the brake switch but the problem remained. We took the vehicle to our local mechanic who ran a number of tests and determined the fault to be within the BCM module. Tests performed. They measured the voltage from the brake switch and validated the proper voltage was there. They went to the interlock solenoid at the shifter and verified the solenoid is functioning properly when provided ground. They went to the BCM (Body Control Module) connector and provided ground from the connector to the solenoid to validate there's no problems with the connectors or wire and this worked. Based on these tests, they have determined the BCM module to be at fault, either not detecting the brake is depressed or the BCM is detecting it, but it's not providing the ground needed to the solenoid. At the moment, we have resorted to pressing the shift lock release to operate the vehicle.
