Subaru B9 Electrical/Lighting Problems



  • yoyodkyoyodk Posts: 28
    If it's just one of the two lights on the driver's side, then it probably needs to be replaced. Both of my lights on the driver's side went equally faint and then eventually out. I took it into the dealer during my 60K service and asked them to look at it. They came back and said the lights were "inoperable". Bunch of morons... Next time my car is in for service I am going to take it in to a different dealer and get an estimate to fix it. I won't pay a bunch of money to fix it, though...

    '06 B9 Tribeca. Fog lights cracked right away. Had brought this up at the dealer but was never documented. Once the first light burned out from moisture, I asked again about replacement. No joy. Out of warranty and wasn't documented. Called Subaru, still no go. Tired of fighting with them. Love the car though. 110,000 miles and drives like day one. Brakes replaced at 100,000 for the first time. Only other issue, navigation system LCD is dim for a few minutes when cold. Also, even with Version 2 of the Kenwood maps, still cannot drive me to my house, it hasn't moved in 14 years. :( Also missing many of the long established roads I travel.

    I found disassembly instructions through a google search and printed them out. I am having the same issue. Drivers door light is dim or will not light, intermittently. Passenger door works fine. I tapped the light when first started happening. Suspect a corroded connection, it is rare for LED's to fail.

    Here is a link to the Subaru installation manual. All the information you need for disassembly. :)

    Good luck!
  • My Tribeca left us at 100K and is with it's new owner. Mechanically as you state, the car was good - no complaints about the mechanical components and like all Subies, the 4 wheel drive is superb. But the electrical system and other glitches did not compare to what I was accustomed to with my previous Subaru's. Hopefully they are better now and lesson learned - never buy the first year model of any vehicle.

    I have a 2006 Tribeca. My tail lights, corner lights etc stopped working....they don't come on when I turn the full lighting system on.....they only come on when I use the switch on the top of the steering column.

    Has anyone else had this problem??? Any ideas??

    Did you check the fuses? Some times you can't tell that a fuse is burned out, a small crack may be hard to see.
  • I have the EXACT same problem! Did you get it fixed? What was wrong?
  • I did fix it but not by the dealer - there is a ground wire on the front headlamp assembly that if it becomes loose - it blows the rear taillights and interior lamp
  • Thanks, ok I give, where's the ground wire that comes loose? Is it braded or does it come from the wiring harness? Driver or Pass side? Thank you for your help!
  • Hi, I have a question about my low beam headlights. I own a 2006 Subaru B9 Tribeca. I have had both low beam bulbs replaced in the past couple of months at Wal-Mart. Since the second one was replaced, I've had a heck of a time driving at night. The lights seem dimmer, or possibly just not aiming straight out. When we first purchased the car a year ago, I was able to see fine at night. Now I need to put on the high beams in order to see well.
    Is it possible that the lights can be aiming the wrong way? Or do I need a brighter bulb? I'm sure I've turned the switch all the way to the full position for the lights. The low beams that come on are the two outer, circular lights.
    Any suggestions would be much appreciated!
  • always use Genuine Subaru parts, common can't you afford $20 that you are using wal mart made in china products. You earned what you paid for.

    Make sure the lenses are clean - my wife's Forester wasn't lighting up the road well, and when I looked they were just filthy. Cleaned, and all better now.

    other thing that may have happened is that the bulb blew out and coated the inside of the lens with [non-permissible content removed]. if so you will need to find a long swab like the doctors use to clean out the inside of the lens and then reinstall the bulb. you can tell if you clean the out side and its still dim...

    also make sure that the LOW beams are actually working and your not just on the daytime running lights...

    do they switch from low to high beams when you toggle the high beams?

    and no real way to put them in backwards, they have a notch and then its just plug the wires into the back.
  • Thanks for the reply. I will see if the lens is clean. When I go from the daytime running lights to the low beams I do see a difference, just not a significant one. When I switch to the high beams, a separate set of lights comes on, as well as the low beams and I can definately see the difference.

    Thanks for the advice.
  • I started having electrical problems with my 2008 Tribeca after driving it cross country in 2009. The map lights in the interior come on when I go over bumps, make turns, and if an adult is sitting in the passenger front seat. I have had my brake lights go out several times and in 2 years had to have them replaced three times. I have also taken it to the Dealer twice and they cannot recreate the issue. Does anyone have insight into what might be going on? Thanks!
  • they propably did not set those lightbulbs right in the seat .have simillar problem when I done it for first time on mine.Have them recheck it at dealer NOT at WASHMART!!!!They will check it for free I'm sure of it.
  • I just bought an 08 TriBeCa and having the same issue with my lights and back door light come on automatically after running over a bump or making a sharp turn. These lights actually need to be open manually so I do not understand it myself. It comes on then after awhile goes off. I made an appt last week to have it checked this week but I haven't been able to recreate the issue so it would have been no help to them so I canceled appt for the meantime. Have you been able to resolve the issue?
  • I was able to resolve this issue. The Subaru dealership in Austin, TX, took my door apart and found there were some wires that needed to be replaced and that solved the issue. I have not had any problems since. I had also had the door switch replaced prior to that.
  • Thank you, I thought I was totally losing it. Hopefully it's covered under warranty as I just bought the car recently. I hope mines gets resolved as well, will post updates once it gets resolved. :confuse:
