NHTSA complaint #10695320, filed 2015-03, 85,000 miles

“Purchased a 2007 Buick Lacrosse less than 2 months ago. Within the first month the low beam head lights went out. Took back to the dealer and they replaced the head light module. No the low beams are not working again. Now the dealer is telling me I have a faulty fuse block under the hood.”

NHTSA complaint #10822450, filed 2016-01, 88,888 miles

“We were 60 miles from home having dinner. Got in the car after dark to come home, started it and no headlights. Low beam headlights failed to come on whether by auto or manual switching them on. We had high beam but no low beam or daytime running light. This is very dangerous. It is our only vehicle for daily driving. We need this repaired under the 12-1-2014 recall from Buick.”

NHTSA complaint #10664467, filed 2014-12, 122,220 miles

“While driving down the highway one night the low beams suddenly went out. I was force to use the high beams until I could pull over. Inside the car I could smell something burning, something electrical. Once I pulled over I notice smoke coming from under the hood and that the fuse block under the hood was on fire, which hold fuses and relays. The two relays that was affected were the low beam and high windshield wiper, so they no longer work.”

NHTSA complaint #10508895, filed 2013-04, 67,300 miles

“A improperly shielded wire grounded out and caused the under hood fuseblock to melt, some reports on line state that the car caught on fire from the same problem. Came out of restaurant and car wouldn't start. When the hood was raised we could smell burning rubber. Had I been driving it could have been very serious reported to GM to try to get reimbursed. Said because it wasn't on recall that they could not help us. The purpose of the fuse box as we understand is to prevent this from happening.”
