My passenger headlights keeps going in and out. The wiring harness has been replaced twice and it still does it. My check engine light keeps coming on for the evap system even though its been replaced.

While driving my truck on the interstate and pulling a travel trailer, the driver's side front tire had a blowout without warning. My truck and trailer momentarily swerved but I was able to regain control and pull over to the right shoulder. I heard the remaining tire tread strike the wheel well repeatedly before I could stop the truck. The blowout caused extensive damage to the fender, wheel well liner, battery, headlight bracket, bumper and wiring harness. Aside from the body damage, numerous wires were torn and rendered the truck inoperable. Due to the amount of damage, my insurance carrier deemed the vehicle a total loss. I'm shocked and dismayed that the tire failed. The tires had a 60,000-mile warranty on them, but had been in service for less than 22,000 miles. I checked the tire pressure before starting the trip. My TPMS did not indicate a loss of pressure during my travels. The road was flat and in good condition. I did not strike any objects on the road. Because I was pulling a trailer, my speed was approximately 50-55 MPH. Upon further inspection after the blowout, I noticed a large hole in the tire casing. I presume that the tire deteriorated from the inside out, and ultimately resulted in failure. I'm lucky that traffic was light and that I was not near the edge of a cliff or mountain road. Although I lost my truck, this blowout could have had much more serious and dire consequences for myself and others.

When I use the driver side sunvisor and flip it down to block the sun, it shorts out the electric ovethead lights. I flip it back up and after shutting off the vehicle and waiting sometime it comes back on intil I flip it again . Happens when stationary or moving. Has happened about a dozen times now.

My passenger headlight works intermittently. The bulb is good. The wiring harness inside of the housing has been changed and did not solve the issue. It will work for a month or so then not work.

The automatic headlights shut off in the dark for no reason. I was driving on a back road with no street lights. I was coming into a turn and all of a sudden the headlights shut off. It was pitch black and the headlight switch was in the auto feature. I quickly reached and turn them on manually. This was very dangerous. If I wasn't on a road I normally travel I would have wrecked.

When I tried to switch my headlights from dim to bright, they wouldn't stay in bright. After several attempts the brights would not come on. When I signalled to turn left, the left headlight went out. When I signalled right, the right headlight went out. When I stopped and set the parking brake, both headlights went out. Seems like my truck has a ghost onboard!

The headlights are not adequate to see safely at night. The lights do not shine forward of the vehicle enough to be able to see what is ahead at night, such as curves in the road. Also, the lights do not project to the side of the vehicle enough to see when making a hard turn to the right or left. They do not provide any light at all when turning. I sometimes have to roll down the window and stick my head out to scan for obstacles as best as I can on dimly lit roadways. I can use my high beam lights in traffic and never get flashed by other drivers due to my lights blinding them.

The headlights on this model dodge ram (2500 slt mega cab) do not provide adequate illumination at night. My headlights are adjusted properly for alignment by the dealer but the bulbs just do not provide enough light ahead or to the side of this vehicle. The dealer can only "check the connectors for proper installation" under warranty. I have not been able to get a response from chrysler.
