Buick - Lacrosse :: 2006 3.8l Engine Developed A Clunk Type Sound
Mar 16, 2012
I 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?

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.

I 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.

2006 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.

So out of no where I have a Clunk type sound coming from my steering column. But only when I turn the steering wheel five percent either way. Steering is still 100 percent responsive though.

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.

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?

For 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.

Love 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.

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.

We 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?

The 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.

2008 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.

I get a grinding type of sound when I am braking but only when I come to a complete stop and then again when I release the brake. It is only for a second but it is loud and doesn't sound good. What could be wrong. It also is much worse when it rains.

The first thing is that suddenly there's a clunk type noise from the transmission when shifting in to or out of 2/3/4. Also, when I'm in one of those gears, letting off the throttle and then re-applying lightly causes the clunk noise. However, I haven't noticed any actual performance difference, just the new noise. It's loud enough that I can hear it over the radio at a reasonable volume, and it may or may not be my imagination but I think I can feel it through the floor of the car.
The next thing is that in the mornings, the car seems to have trouble getting in to gear from a stop. So I'll pull up to a light, then stop, and if I take off the brake and get immediately on the throttle, the car will lurch pretty bad, even if it's only a little throttle. I've found that if I let off the brake, and wait specifically to hear/feel the transmission kick in, there's no lurch and everything is fine.
Also, on that same note, sometimes when I let off the brake at these times, the car nearly stalls. It hasn't stalled yet but it's felt close a few times.
As well, from a cold start, there is what feels like an absolute ton of engine braking in second gear, I can feel the car pulling back immediately after I let off the throttle, and this seems strange and new as well.

"Clunk" noise when shifting from P or R to D happening to me right now with my '06 GS300. It doesn't happen all the time, but it happened all day yesterday and sounded pretty serious. Took it into the dealer today, still under warranty, and of course it wasn't happening. Tech said he will keep it overnight, let it cool down, and check transmission fluid level which could be the issue. If that isn't the issue they said it could just be a "normal" sound. My wifes 2006 Sequoia shifts smoother and doesn't make a sound when you go from P or R to D ... Don't tell me it is the break pads releasing either because that is just as far fetched as the normal theory.

What could cause a suspension noise? Dealer says nothings wrong... Going over broken pavement etc it makes a nasty clunk sound sometimes, only at low speeds above 40 kmh... It's as if it goes clunk/crick, then goes away, switches sides then comes back...

I have a 2006 Sonata LX with 91,000 ,miles and today it starting making a clunk sound when I would accelerate normally as it was going from 2nd to 3rd gear. My question is this: I have 91,000 miles on it and have owned since new in 2005 (8 years). Does it sound like a transmission problem and would a transmission problem be covered under the 10 year, 100,000 miles warranty?

For a few months now I have been hearing a tap clunk type noise coming from under the car when I shift the auto trans into drive and reverse. Also sometimes when the car is slowing when driving I hear the tap sound as it shifts into first. I drove in by my local dealer and they listened to it and said Elantra transmissions can get noisy there is nothing wrong. They told me I have plenty of Warranty left so if something happens I will be covered.

I wanted to pass along the results of a brake issue I encountered in my 2010 Prius (15K miles) and report to interested Prius owners how the issue was resolved.
Problem: In the last second (or so) coming to a complete stop I noticed a few light clunk type sounds, like something was loose up front. I never experienced any degradation in the braking performance.
