I got an 07, last summer painted the rear bumper. Took it off and found a crushed harness under the mount. Mine can't be the only one like this.
Have you lost your turn signals or high beams? My 07 has been losing all of the things you described as well as the high beams, power windows, power locks, etc. from time to time. Its caused by the BCM going into safe mode. Im installing headlight relays soon as my HIDs are causing the BCM to think something is awry. If you have any aftermarket electronics try removing them.09 3.7 I5. To start my drivers side rear assembly is out. All 4x4 otf switches wont light up, Guage dimmer light wont light up and dimmer doesnt work, also my blower lights and #s 2 and 3 dont work for heat/ac.I did have the hitch wire assembly attached but i detached it after the left rears went out.I had an after market pioneer avic professionally installed.
