4 Exterior Lighting problem

Failure Date: 01/16/2014

The rear passenger tail lamps are dimming to about half the normal strength. The bulbs are all fine, but I am getting notices on the dash that the lights need to get checked. I checked the rear light harness and it appears the electrical connector has melted so that it can't be removed from the component that actually holds the bulbs. I am concerned that this might be a fire hazard. The electrical failure also seems to be affecting the horn. There are two horns on this car. One is on the drivers side and one on the passenger side. The passenger side horn is not functioning. It appears like there is weak to no electrical power on that side of the car. This is extremely dangerous too as I can't warn other cars on the road if needed.

5 Exterior Lighting problem

Failure Date: 10/14/2013

All exterior light bulbs keep burning . -seat belt stays on even is used. Air bags comes on and off. The engine makes like high idol noise like the car wants to move even its brake.

6 Exterior Lighting problem

Failure Date: 09/23/2013

All right rear lights failed. Starting to get messages of rear left lights failing, but non have actually failed yet. I took off the back panel in the trunk to change the bulbs and found the wiring has melted through the plastic housing unit, it looks like the wires and the unit have been burned. After taking the car to the dealer, he said it was starting to happen to the left side of the car too. This is costing me $500 for the entire replacement! I've read so many complaints about this same issue. I'm amazed that there hasn't been a recall issued yet. Burning up wires in the trunk has to be a safety hazard!.

7 Exterior Lighting problem

Failure Date: 08/01/2013

Right taillight failure. The entire taillight is not working so I removed the cover in my trunk to look if any of the bulbs were blown. When I removed the cover it smelt like something was burning. After further examining the taillight assembly you can see what that the wires were either burnt or shorted out and the plastic connectors have a brown to black film on them. Not sure if this has been a recent issue but wanted to see if this was something was being investigated as a potential recall.

8 Exterior Lighting problem

Failure Date: 07/26/2013

Inside dash warning saying "check rear right signal lights" and right signal flashes quicker than normal. Upon inspection, lights were working but bulb holder inside lights and connection harness was melted where the brown wire was. Unable to remove harness out because the connector was melted on. Smelled like fresh burnt plastic. Severe fire hazard!.

9 Exterior Lighting problem

Failure Date: 07/24/2013

Driver side bulb burned out. Replaced bulb. After further inspection noticed the passenger side lights dimmer than right side. Replaced the passenger side bulb with new one but remained dim. Noticed that bulb assembly gets very hot and also noticed a dark spot that appears to be indication of burning like a short circuit.
