Underhood fuse block caught on fire from the headlamp driver module micro-relay #35 melting down. Headlights went off and the battery started draining. Pulled over, turned off the car, and opened the hood to discover that the #35 micro-relay was arcing and had melted itself to micro-relays #44 windshield wipers and #38 air conditioning compressor. Both windshield wipers and air conditioner was off at the time. Even though the engine was off the relay continued to arc and was melting the underhood fuse block. Grabbed an insulated set of pliers and pulled the #35 micro-relay (the #44 and #38 relay came out at the same time). Arcing stopped with the micro-relays removed. I have filed a previous report on the #35 headlamp driver module micro-relay, because it had turned off the low-beam headlights while I was driving, at night, on the highway. Turning the light switch to manual-on did not turn the low-beam headlights back on. I had the #35 headlamp driver module micro-relay replaced and it too proved to be defective. After just a few months, it started turning on the headlights about 10 minutes after the vehicle was turned-off. Had to have my vehicle jump started, replaced the battery, and replaced the #35 headlamp driver module micro-relay, yet again. The 3rd #35 headlamp driver module micro-relay, caused an electrical fire, costing me over $700 to repair. Apparently there is no fuse to prevent the melt-down of the micro-relays. There is no caution, and no warning in the owners manual, to advise the user about what to do in the case of the low-beam headlights suddenly going off. There is no protection against an electrical fire being caused by the #35 headlamp driver module micro-relay, or any other relay from starting an electrical fire.
2008 Buick Lacrosse electrical complaints
Page 4 of 4: complaints 71 to 85 of 85, newest first, as owners wrote them.
The power door locks do not work either with door switches or the remote fab. Only way to lock or unlock doors is to manually lock or unlock doors, except drivers door which will lock and unlock with key. Remote start doesn't work because door can't be locked with fab. Took to dealer and was told that all 4 doors needed to have the actuators replaced. Priced over $1000.00. They offered to pay $350.00. It seems to me that there are problems with the control unit that sends signals to actuators, both by door switches and the fab. Based on the complaints filed I am not alone with, not only, this very expensive problem, but a severe safety issue.
Experiencing problems with the automatic door locks. Sometimes they work & sometimes they don't! Sometimes when I hit the unlock button only the driver side unlocks. When I hit the lock button I have to manually lock all passengers doors. Also having problems with the instrument panel lights intermittently will fail causing limited visualization of the gauges. Also have a clunking noise on the right side.
We have a problem with our automatic power door locks and the remote start feature. They don't work, either by key fob or the power door lock buttons in the car. The only way we can lock our doors is manually. We took to the dealer believing it to be just the drivers door but they told us all our door lock actuators needed to be replaced, close to $1000.00 repair with no guarantee that the actuators are the true problem. After going on the federal safety agency site I see that we are not alone with these problem. I can understand a actuator going bad, but not all of them at one time. I am a former dealership gsm and very aware of "normal wear and tear" and "defects". I've never in my 35 years in the business seen this with door locks. I was insulted by their offer to repair them.
Tl* the contact owns a 2008 buick lacrosse. The contact stated that the lights con the instrument panel would fail sporadically, causing limited visualization of the gauges when driving at night. The contact took the vehicle to the dealer but the dealer was unable to diagnose the failure. The vehicle was not repaired. The failure mileage was 47,000.
Tl* the contact owns a 2008 buick lacrosse. While driving approximately 65 MPH, the contact noticed that the fuel gauge displayed an incorrect fuel level even though fuel was in the fuel tank. Then, the engine stalled without warning. The vehicle failed to restart and was towed to an authorized dealer where they advised that the fuel tank was empty. The technician dispensed one gallon of fuel into the fuel tank and was unable to detect a problem. The failure had not yet recurred. The manufacturer was made aware of the failure. The approximate failure mileage was 35,000. Updated 07/08/11*lj updated 07/18/11
The fuel level sensor located in the gas tank has failed three times in the past three years. Each time the dealer has replaced the fuel level sensor. This has occurred first in dec. 2008 (7574 miles), then nov. 2009 (21145 miles), and now dec. 2010 (37344 miles). The service tech at the dealership informed me that this problem is fairly common (in fact, when I took the car in for repair this time, there was a pontiac aztec with the same problem being repaired). The tech also told me that the cause is sulfur in the gas causing the small wires in the sensor to corrode and eventually break. The module error code error is p0463.
Tl*the contact owns a 2008 buick lacrosse. While driving an unknown speed, the contact stated that the lights on the instrument panel suddenly began to dim before they eventually shut off. The lights turned back on. The failure occurred intermittently. The vehicle was taken to an authorized dealer but the failure could not be diagnosed. The vehicle had not been repaired. The failure mileage was 30,400 and the current mileage was 30,500.
Remote, remote starter (rke) fob for car stopped working properly. Replaced batteries even though dic did not show batteries needed changing. This maybe a problem also. Sometimes it works, sometimes it doesn't. Worked perfectly fine, then problems started. 99% of the time it will not start the car. 50% of the time it will or will not, lock or unlock car. I have tried resetting and/or personalizing keys & fob through dic center. Car will sound horn to show it has been reset properly, but isn't. Still does not work properly also when using rke, the door lock knob will not come up all the way and the door is not unlocked. Also, the door lick know will not go down all the way if I use the rke fob. If I use the key to unlock the door, the door knob will come up all the way and the door will unlock. If I use the rke fob to lock the door, the door knob will not go down all the way and the door will not be locked. I have tried using the fob away from all possible interference which I do not think is the problems, it still only works sometimes.
Instrument panel lights and radio display lights go dim, very hard to read. Does not correct if car is turned off then back on. Does not correct if battery is disconnected then re-connected. Does not happen at any certain time, just happens.
Air bag passenger seat light shows off even with a passenger seated. Passenger is well above 80lbs. Indicator light on dic shows seat belt not being worn even when a passenger has one on.
2008 buick lacrosse. Dash light problems *gr the consumer stated he has driven as far as 125 miles in the early morning with no dash lights. The only thing that could be seen, was the odometer and trip mileage. The consumer stated the dash lights worked sometimes.
While driving at 55mph I ran over a road bump and my 2008 buick lacrosse super shut off(stalled). I coasted to the burm, hit brakes to a stop. The car started on the first try. Continued my trip with no incidences. Took to dealer and no codes showed in their computer. Called gm customer assistance and they gave me a case number. No bulletins. Scary to drive. Traffic was light this time but may not be the next time.
2008 buick lacrosse dashboard is malfunctioning. Consumer states that the dealership can not do anything to fix the problem. *nj the consumer stated he was unable to read the instrument panel while driving during daylight hours.
Instrument panel will not light up when turned on. Cannot read speed and other gauges during daytime. This is the third buick of mine so afflicted.
