I have flat towed behind my motorhome 9 times. 4 of those times the Jeep failed to start after being towed. Any idea why?
Additional information: Automatic Transmission, V6.
Each time the Jeep was placed into and taken out of recreational towing mode I followed procedures described on pages 397–402 of the 2019 OM.
At the end of the procedure to place the Jeep into tow mode, the START/STOP Ignition Button was left in the OFF position. It was not left in the ACC position while being towed.
There was no rapid clicking associated with a dead battery when the Jeep would not start. The battery was checked with a voltmeter and found to be fully charged. I simply put my foot on the brake, punch the START Button and nothing happens.
Troubleshooting to isolate: without connecting the Jeep to the motorhome, I placed the Jeep into tow mode and then took it out of tow mode the next day. The Jeep started every time. I must have done this 8-10 times. The problem only occurs after the Jeep has been towed behind the motorhome, the last time being after the troubleshooting to isolate the problem.
The only electrical connection between the motorhome and the Jeep is a 7-wire power cord that operates the Jeep’s left/right turn signals, brake lights, and taillights.
The charge line on the 7-wire power cord was checked and found to be providing proper voltage from the motorhome to the Jeep battery.
None of the 3 different Jeep dealerships that have investigated the problem have been able to replicate the problem or find anything wrong.
