2006 LaCrosse stalls at random when a/c is on under 30 mph. it can go all day without a stall or can stall 10 times on a short trip. diagnostics shows nothing and every mech who has seen it is stumped including dealer. car restarts immediately and has no other symptoms. is it haunted or what?
View 7 Replies2008 Buick Lacrosse CXL .. My son said the Oil pressure low light came on when he tried to start the car. It didn't want to start.
When I got there two hours later, it started but had a check engine light. But no low oil pressure light. Sounded like it was missing.
Code from computer came back P0300 "Random/Multiple Cylinder Misfire Detected". I cleared the code. Revved the engine to about 2000 RPM's and the CEL came back on.
Same code. When idling it feels like it's missing. The plugs look good, I am going to replace the ICM.
My Dad left me his 2006 Buick Lacrosse. Beautiful car. But I had the problems with the low beams not working and had to use the high beams to get home. My son replaced the relay for me and it worked fine....for awhile. Then I had to have the relay replaced again (the car parts place) ... it worked for a few months, then it FRIED ! Smoke was pouring out from my hood and the whole relay box melted. Now my car won't work at all ! I cannot afford to take it to the dealer. I would like to get it fixed so I can sell it and get a car easier to fix.
View 1 RepliesFor the 3rd time, my stepmom's car is in the shop because it won't start. They said it needed to be reprogrammed, but that didn't work. They seem clueless; if she ever gets the car back, she'll be afraid to drive it.
View 11 RepliesLove my 2007 Buick LaCrosse. It has just under 40,000 mi. Oil gets changed regularly, etc. Never had any real problems (knock wood). Past six months or so, the airbag symbol lights up for no apparent reason, stays on a little while, goes off, maybe comes back on again same day, maybe not for a week or two. Took it to local Buick dealership service department twice; they can't find a reason & said that the computer check doesn't even show it coming on. Should I be concerned? Will airbags deploy if/when needed? Don't know what to try next, if anything.
View 3 Replies2006 Buick Lacrosse, CXL, 78K miles. 6 months ago, the check gas cap message came on. The gas cap was replaced. The message is still on. Soon after, the engine light came on as well. The Buick dealer said (without running a diagnostic or looking at the car) we needed to replace the catalytic converter and it would be expensive! Had 2 diagnostic tests run - one at a garage and one at an auto parts shop. No codes were detected.
Whenever the car is close to its 3k oil change, an "'oil low" message appears. The oil has never been low, it's an annoying message to get the oil changed. As the gas cap/engine light came on shortly before its 75K mile check, could this be the same case?
The car runs great and there has been no change in gas mileage.
I have a 2006 Buick Lacrosse with the 3800 Series 3 V6. It has 140K miles. Lately on warmish starts (after shopping for example) the car will start then slowly die (not all the time but a good chunk of the time). It starts fine when truly warm, and usually when it's cold it's fine too. It runs great otherwise. It never stalls or dies otherwise.The car has new plugs and wires, a newish battery, a new air filter and I cleaned the MAF sensor. I've only had the car about 6 months, and noticed the problem in the last couple.I scanned for codes and there are none, also there is no check engine light. The car doesn't have an IAC valve or a fuel filter (I know those are common culprits)But it starts easier when cold (even -20) than when warmish. Here are two videos I took of me starting it. *note the coolant temperature gauge. It's partially warm.

Bought 09 Buick Lacrosse CX 4/11 with 26K mi. Jun. '12 passenger airbag began turning off intermittently with passenger in seat. Buick shop replaced pps module. In 2/13 it began doing it again. This time buick shop said the computer was being confused by placing items on the seat weighing less than 75-80 lbs. and didn't know whether to stay on or turn off. They "reset" computer. Been placing items on the seat ever since buying and never experienced this problem. Is the airbag sensor that sensitive? It's doing it again, a few days after the shop "fixed" it with the reset, and I only placed a newspaper on the edge of the seat and snatched it back up immediately.
View 1 RepliesI have a 2006 Buick LaCrosse. The low beam headlights have stopped working. I thought that maybe the bulbs needed changed (since I usually have to change them every 6 months) but after changing one with a brand new bulb, it still doesn't work. The "old" bulb looks ok. The fuses are also good (I checked them with a multimeter.) The only thing that I see in my shop manual is something about the ambient light sensor. If this has gone bad, would that cause the low beams to not work? The high beams work fine. The low beams will not work with the headlight switch in the "auto" or "on" position. I don't see any DRL relay or fuse in this car.
View 17 RepliesWe purchased a new LaCrosse CXL in 2005. Its speedometer now shows 90,126 miles. The 5W-30 motor oil has been changed every 3,000 miles with no indication of oil loss until around 65,000 miles, when I began noticing a slight drop in oil level on the dipstick (about 1/4 quart) within the 1st 1,000miles following the scheduled oil changes. I then added enough oil to bring the oil level back to full. Within the next 1,000 miles, the oil level again shows oil loss of about 1/4 quart. This has continued over the last 4 years. The car is garaged, and I have never seen any sign of an oil leak on the floor. I have alsodriven behind the car several times, and have never seen any sign of oil smoke coming out of the exhaust pipe. Both my Buick dealer and oil-change shop manager can offer no explanation as to why this oil leakage problem developed and continues. The oil shop manager says he has other Buick customers with the 3800 V-6 engine that complain about this same problem of engine oil loss.There have been no mechanical problems with the car and with the exception of the oil "leak" we have been well pleased with the car. Where is the oil going?
View 6 RepliesThe brakes on my 2007 LaCrosse do not feel like they are engaging when I am reversing and the car is cold (first thing in the morning or first thing after work). The pedal feels very stiff/hard and the car doesn't feel like the brakes are stopping it. Every time I apply the brakes after that first time, they behave fine. I had the front brakes repaired/replaced but the problem persists.
View 2 RepliesI have a Lacrosse that has 110,000 miles on its engine. The car has has regular maintenance and oil changes at suggested intervals ( 3000K). 2000 miles into this oil change, The engine developed a clunk type sound. I checked the oil and it was dirty so I took in for another oil change. I was quite surprised to hear that I needed a new engine immediately. They could not tell me what had failed but I was in need of a $4000.00 engine transplant.I requested that they change the oil and give me back my car. I have taken it to another shop and they concur with shop one. Shop two took it to a third shop while they had it just to confirm. After the oil change, the repetitive clunk became a persistent tap. Is my engine really going to implode in the near future? Is there anything that can be done to extend the life of the car?
View 18 RepliesI have a 1999 Buick Regal GS with a supercharged 3.8 liter engine and 161,000 miles. I bought the car off of my uncle and he said he would have to change plug wires every month to month and a half because it would start missing so bad. When I first drove the car it would quit on me at red lights and in parking lots, it only seemed to do it at low idle speeds. I live on a hill with a blacktop road and I had to give it a lot of gas just to pull the hill it was missing so bad. The plug wire had a lifetime warranty on them so I replaced them and it stopped quitting on me but I still had a bad miss at random but not as bad it would just be like hard jerks. I added sea foam fuel injection cleaner and had the fuel filter replaced. The mechanic checked the spark plugs and he said they were like new AC Delco. I also cleaned the MAF Sensor (the mechanic told me to and how) because the engine did not run steady at idle and it seemed to work that, but not the miss. Could my problem be the plug wires? They are carquest brand 7mm wires.
View 6 RepliesHaving a little issue here with my 2000 buick regal. There is an occasional instance where my car won't start for a while, then after several attempts, itll start up. When I turn the ignition key, it will not even attempt to turn over. I can't hear any clicking noise, but the lights/radio/ac will work . I know I know, it takes a lot more to start the motor than those things. What gets me most is the randomness of it, and it will eventually work without me really doing anything. I figure if it were a bad battery then it wouldn't start up at all after several attempts. I can see a bad battery connection being an issue if I moved the car and it started working, but I can sit there and just keep turning the switch on and off and that seems to be enough most of the times.
Usually it will come on within 5-10 minutes, and if I knew it would always come on in that amount of time, it wouldn't be a big issue. But, once it took over an hour before it came on again. It usually does it during the day and after I've been driving it a while, but not always. Just last night it did it for a few minutes and I hadn't driven it all day and it was at night (temp was in the mid 70's, usually hotter than that a good amount during the days) I've checked the fuses and relays and they seem to be working.
I own an 87 Buick Lesabre Limited Coupe [URL] ..... I have driven it for the past 6 years with no major problems, but just now it has begun to have a stalling problem. The engine just shuts off at random times. Doesn't matter if you're at a red light or driving in traffic. She will stall, then after 5 minutes will start up again, and stall again. So, I took to it to my mechanic & he changed the ignition module & mass air sensor. I picked it up, and the 'Service Engine Soon' light went on, and then she stalled a few minutes later.
So, I drove her back to the shop (stalling several times on the way), and my mechanic changed the crank position sensor, and she still died. He read the trouble code 42, so he changed the ignition module again. I picked her up yesterday, and she made it home without stalling, but the 'Service Engine Soon' light still goes on after 5 minutes of idling, which leads me to believe that the problem lies somewhere else. Could it be an electrical problem (wiring, fuses, computer) that is causing the 'service engine soon' light to go on & the car to shut off? What else could it be?
I have a 2002 Buick Rendezvous with a 3400 sfi engine. The vehicle runs perfect except random stalling when you are stopping or pulling out. It seems the vehicle has a random low idle unless the air conditioning is on at which time the idle stays around 700 and the vehicle does not stall. I had a repair shop clean the throttle body which made no difference. I replaced the IAC valve and air filter yesterday and still no change. Also was wondering if you unplug the IAC valve should the idle change because it has no effect on the idle at all when I unplug it while the vehicle is running. Really cant afford to just start replacing item after item with no result.
View 8 RepliesI have recently noticed that my car will stall out when I get up to about 20 mph. My car starts fine, no check engine light on. I has a tendency to just die in the middle of the road at times too. I have changed the spark plugs, spark plug wires, and a new fuel filter. Do I need to change the mass air flow sensor? Or the crank position sensor? I have no problems starting the car either. Runs good when it runs.
View 10 RepliesI got my Touareg 2 months ago, and has been nothing but trouble. I also own a 1997 E39 BMW 528i, and I have never had so much problems with it in 8 years as with the VW in 2 months. Just plain terrible. There is now a strange problem, and it looks like the local service could not localise it properly.
My engine stalls at random. It usually happens at low RPMs, at a red light stop, etc. The engine usually goes bananas, the revs going up and down, and it looks like its choking. Sometimes switching to N and then pressing the revs up a few times works, but not always.
Sometimes the EPC and the triangle (exclamation mark) lights come up, but not always. It happened to me, that the engine just plain stopped.
It even happened to me when I was going slow down the hill in front of my house!!!
Can you imagine, initially I was firing up the engine with the button, having the key in my pocket.. And when the engine stalled, I lost all the servos, and the steering wheel just LOCKED!!!
I mean this is really serious. Since this happened twice, I am always using the key in its place... The local service just changed some electronics which supposedly monitor the engine RPM. It did not work...
I have a 2000 crown vic, police interceptor..... 1st.. car started idling rough had the codes read gave misfire on 4 . So we had the boots and spark plugs replaced. Car ran fine for like 3 days then engine light came on again.. running rough... code read misfire in 8 so had the coils on 4 and 8 replaced... ran fine for all of 2 weeks. Again engine light came on... now showing a misfire on 7, but car runs fine..??. Anyways I noticed my battery gauge was marking a really low charge... but as soon as I would get on highway it would jump back up to normal...
It did this for a couple weeks, then I noticed the gauge was marking really low car was losing power... I have a new battery and alternator on car already. But still I had them tested; both tested fine... Then car kept stalling at stop signs ans red lights went ahead and exchanged alternator 4since its under warranty anyway. This cause the charge gauge was reading normal.. but car still kept dying... so replaced fuel filter... didn't replaced tps and mass air flow sensors too...but it still keeps dying on me. Now codes are coming up misfires on 4&8! Why does my car keep stalling and what would cause these random misfires especially when these coils have been replaced already???
So I have a 2000 Buick, and it generally starts. However, twice now at random times the car hasn't started. It doesn't turn over, but makes a buzzing sound. The strange thing is, that usually after leaving it alone for a few hours, it will start as though there are no problems. I assume it's some kind of electrical issue, but I would love some input on the possible problems with my car.
View 2 RepliesI own a 1999 Buick Park Avenue - that stalls. There is no pattern to the stalling.It stalls when I start driving, after I have been driving for a long period or when I just begin driving. It stalls when I turn a corner or on the highway, when I am at a stop sign or a red light. It is baffling. My mechanic has tried a number of solutions, including replacing the crankshaft sensor, however, it still stalls.
