The jeep is now doing it while I am driving. Would be nice to have a recall on this considering its a common problem. I have the lifetime powertrain warranty but of course this won't be covered.

Try the battery wire at the TIPM lug. Disconnect the battery negative terminal. Remove the wire from the TIPM lug. Clean it with a wire brush. Hook it back up and reconnect the battery negative terminal. See if that makes a difference.
If it doesn't, disconnect the battery negative terminal, and raise the TIPM out of its cradle. Disconnect and reconnect each plug. If there is a contact problem, this will usually establish a new connection.

The last resort is to replace the TIPM.

All others were fine. Door locks would unlock with remote none would lock. Turn signals would not flash 3 times when tapping (for passing). Dealer said your warranty does not cover electrical. I asked "how much for the install and tipm?" They wanted to do it at their cost(so they said) at $700.00. After a temper tantrum that only a seasoned 41 year old could throw they stuck to their price. I called a friend that is a service manager for a local dodge dealership here in Michigan. (Thank-You Jody F). I was able to purchase my new tipm for $250.00 and he delivered it to my door. The other dealer said there was 2 to 3 hours labor included in the price. Today a friend...(Thank-You Jacob your the Man!) helped me remove and replace my tipm. It only took about 15 minutes! Really!
Tools needed.
1) 13mm socket with a ratchet.
1) 10mm wrench.
1) Small tip flathead screwdriver.
1) Watch with a second hand or a stopwatch.
1) Extra pair of hands....Mine were connected to my friend and coworker Jacob.
#1. Remove the negative battery cable.
#2. Remove the cap of the tipm.
#3. Remove the lead to the tipm.(small nut )
#4. Remove tipm pop in clips on top that secure tipm to the jeep.
#5. Carefully unplug all of the connections on the bottom of the tipm.(These have gray rotating clips that attached to the plug).They are all color coded/idiot proof to reinstall. There is a small black release in the center push them in with the screw driver then rotate the gray clip downward to release.
#6. Remove the old tipm.
***It helps so much to have one person stand in front of the jeep holding and rotating the tipm and one on the passenger side removing and installing the plugs.***

To replace the tipm do this in reverse order.
VERY IMPORTANT!!!! STARTING INSTRUCTIONS!!!!!!!
Place your ignition key into the ignition.
Turn the key to the on position for 12 seconds.( I used a stop watch)
Then turn the key to the off position.
Then start your jeep as normal and check all of your functions to ensure normal operation.
Thanks to the help from all of you and some help from my friend mine works fine.
Im sure there are photos and maybe a link to a video of an install.
I am not a repair tech. I cant type that great but I hope this will help someone solve their tipm problems. Thanks again to everyone. JEEP ON!

No issues with horn, wipers or airbag light...

Is it the TIPM?
Check connections first since it only happens every couple of weeks?

COULD DAMAGE BE CAUSED IF NOT REPLACED?????
