Had estimate of $500 to replace and program new BCM.. We have towed car home after going to store. I used to drive otr so we got a second vehicle to drive.

Random misfire code won't go away since weeks after purchasing my vehicle which was then under warranty. The dealership replaced the car computer & ignition coil module, spark plugs and the code temporarily went away good enough to pass emissions. They also performed the key recall the code keeps coming & no mechanic or dealership can tell me why but they keep taking my money for a temporary fix.the dealership said I needed a new catalytic converter. I have replaced 5 sensors, the ignition coil module twice, the catalytic converter, all six fuel injectors, the fuel pump and had 3 major tune ups.
