NEED TO REPLACE HEADLIGHT ON DRIVER SIDE OF 07 SUBARU TRIBECCA.

Does seem odd,never heard of Subaru having that odd habit.
I would have thought your dealer would have checked but if not have them or someone check the charging system output.

Generally, it is better to replace both at the same time, simply because the possibility of the other one following after. BUT $150.00? wow, that is not something that would void your warranty if you replace it yourself. The bulbs are as cheap as $7.00 at your local parts store. Save yourself $130.00 and replace them yourself. ^^ Good luck and hope this helps. P.S. If you are talking about the entire headlight assembly, then $150.00 is more than fare.

hi you have to pop the surround peice off on the interior on the other side of the mirror there you will find the screws that hold the mirror on, undo them and the electric plug and repeat to reinstall

Check near the headlight for loose or corroded chassis ground connection to the headlight.

This problem is with out fail caused by a defective ground connection to the headlight bulb, the ground is in many cases found near the headlight under the hood bolted to the inner sheet metal of the fender.

I have a similar problem. The adjustment screw adjusts both the high and lof beams. After changing the passenger side low beam, both sides then pointed at the ground. High beams were fine. I adjusted so the low beams are fine but now the high beams point straight up.

In talking with Subaru Service he said there is a "module". He said after changing the bulbs they should point down then auto-adjust back up. That didn't happen. I haven't found anything on such a module. He said it woul be $109 for adjusting the lights OR for the module.

If I find anything more I'll let you know.

It is Just a bulb. Open bonnet next to the radiator on each respective side is the wires to your headlight bulb. Very straight forward and easy to remove and replace. Good luck and have a great day.

The driver side headlight is dim. This is caused by loose
ground contact of the headlight ground terminal. Have
a check on this by tightening it up or reconnecting to
good ground (chassis).

Same problems. I'm willing to bet that Subaru outsourced their light manufacturing to China, seeing as how the quality of the bulbs are so poor.

I bought a 2006 Tribeca in late 2007 with 27K miles on it. Have about 47K miles on it now and have changed out both sets of the headlight bulbs twice. At present the side puddle light is out and I also need to replace one rear brake light and 1 rear running light. I've kept my last two cars (Nissan & Ford) for no less than 5 years a piece but, I've never had, or heard of so many crappy light bulb issues.

On one occasion, both headlights went out at the same time while returning home from the grocery store at dusk. I stopped at an Advance Auto parts to get bulbs and fix it in the lot but, quickly found out it's going to take a lot more work vs. previous cars I've owned and/or worked on. Not very safe and considerate Subaru!

While I'm sharing, I also had another hazardous issue come up recently. While driving back to VA from MI, the wiper blades ceased keeping the windshield clean. It was snowing a bit and the roads were wet and dirty. I stopped at an Advance, and at a Meijers, and was advised that they only carry the rear wiper blades for 2006, and would have to go to a Subaru Dealer to get the blades. Again, not very safe and considerate thinking on the part of our friends at Subaru.

I like the car but simple maintenance matters are way too complicated and unsafe.

No, you just remove the radiator grill and the side marker light and the headlight housing bolts and it comes out. Not a real hard job and is Real straight forward. Good luck and have a good day.
