Car stalls when driving, no reason. No codes generated per dealer. Also have a problem with horn beeping at random times sometimes days apart. This truck is not driven for a week at times. There may be a correlation between the intermittant horn sounding and the failing ignition. The security system wiring harness and keyless entry system may be tied to an ignition kill switch when the defective keyless entry system triggers the horn. When driving, the horn may not sound as a key is in the ignition and/or the vehicle is exceeding 15 mph may disconnect the final circuit driving the horn. Remnants of a security system wiring may exist whether or not the vehilcle comes equipped with a security system or not. This would explain why no failure codes are ever found. I will go to dealer and ask them to replace keyless electronic module to stop the horn from triggering at random times and hopefully fix stalling problems.
