2004 Buick Rainier Exterior lighting Problems

“Low beams on lighting goes out for no apparent reason. This has happened two times in the last two weeks. Dealership says they just can't find anything wrong. Although they had another vehicle there with same problem. This seems to be a recurring problem with GM SUV's. My 1994 gmc did the same thing and I heard reports of other gmc's doing the same thing. Not good on interstates at night.”

“Headlights fail intermittently while driving. While driving last night the low beam headlights went out. The high beams still worked. This is about the sixth time this has happened. I changed out the headlight relay just before this occurred as I had seen a recall on 2006 and 2007 rainiers showing this as the problem. After a short time the high beams also went out. I parked and turned the engine off for a while and when I restarted the high beams were working again but not the low beams. …”

“This is my second complaint rising from the same issue, I own two 2004 Buick Rainier's and they both have had an issue with the low beam headlamp bulb and connector being melted due to poor connection. This is a costly repair since the GM parts catalog does not list a replacement connector, they would rather sell the entire headlamp assembly. The first complaint occurred on my other Rainier now this one. No headlamp is a safety concern, and due to the wiring overheating and melting could be a potential fire hazard.”

“I have had trouble with the headlights dimming while driving since the beginning, the dealership has several times worked on the problem, which I think has cleared up..so far. Now my speedometer has started messing up, it says I am going 50 while parked and 120 while driving. I only drive short distances and mostly into and back from town 6 mile one way. I have 50,969 miles on my 2004 vehicle, I keep its checkups and oil changes regularly: dealership has records. …”

“Have noticed after a heavy and driving rain that the electrical systems acts up. We call it crazy car! All the dash lights blink & flash, bells ding and gauges fluctuate while the vehicle is at rest and on the move. We shut the engine off, sit for a minute and restart only to get the same thing. That may happen for the entire ride duration or we may get no dash lights at all. It appears to me that there is a short or a moisture that creates this happening because after a few days of good sunny weather where the water has evaporated from the roadways, our beloved rainer comes back to normal. …”
