I put a BUNCH of miles on my car -- have a 68-mile commute one way. So, my 2005 Lacrosse just went out of the extended warranty (102k miles). From day one, this car has had a hesitation upon acceleration -- kind of like a fuel line issue. The RPMs go way down (it's even stalled twice) and pushing the gas pedal does nothing. It will "catch" after a few seconds and then take off normally. Can't find a correlation between where I buy gas or the weather temp or conditions or really anything. It's so sporatic that the dealer hasn't been able to fix it -- they can't make it happen. But, as soon as I drive off their lot, it does it again. One time and one time only, I did get a blinking check engine light. I called OnStar to get them to run a diagnostics while the light was blinking. The only thing that they could tell me is that it was getting a "loss of power" error. So, anyone else out there own a 2005 Lacrosse or have any idea what's up with this lemon of a car??? Additional Details - The dealer has looked over the fuel system; I've added fuel injector cleaner to it; I've added gas treatment; the dealer changed out the catalytic converter. Can't think of what else to try.

WELL BUICK LACROSSE HAVE TIMING CHAIN.THE SERVICE SCHEDULES MAINTENANCE DONT GIVE NO TIME CHANGE.I SEEN TIMING CHAINS LAST OVER 100000 MILES OR MORE.IF YOU NOT A HARD DRIVER.TIMING STILL GOOD.CHAIN OKAY IF YOU HEAR CHAIN NOISES OR YOU NEED TO REPAIR FRONT TIMING COVER SEAL THEN REPLACE TIMING CHAIN.YOU BE THE JUDGE.IM NOT GOING TO TELL YOU NO OR YES.IF YOU GOT THE MONEY.WOULDNT HURT NOTHING.JUST THE COST AND LABOR..
Most "common" cause is and engine misfire that causes unburned fuel to enter the converter and overheat/melt the catalyst. The converter is covered by 8yr/80,000 mile warranty for defects, and may be covered thru Kia. On a positive note we have a 2005 sedona shuttle van a work with 250,000 miles on it and qoing strong.
remove electronic power steering (EPS) motor. remove the 4 bolts that hold on the motor housing. remove the housing. using a tooth brush, clean out the 'brush' dust from between the commutators. don't use cleaner spray as you might degrease the bearings. don't use anything metal to clean out the dust you might scratch or nick the commutators.
this solution has worked for over 500 miles for me. I'll keep you posted.
check all fluids and check the trans with engine running.after you check tranny fluid turn off car and check the rest of the fluids.
then put a obd2 on the electrical connecter and verify the trouble code is from the tranny.
there may be a recall on some things with that.
also on the kia it still maybe under warranty.
these are all good ideas to start with on a car that new to save some fast money.
something is having a hard time at this point of warmup.it may be the transmission but it very well could and may wind up being from a power loss from the engine.
keep me posted
hope this helps firstname.lastname@example.org thank you
the 2.7l has a sludge problem. This could cause the stalling and loss of power. There's a few fixes, the new water pump (which is part of the problem) doesn't dump coolant into the oil pan. Easy way to check is to simply drop the oil pan.
I took my car into the dealership on friday 02-13-09 only to find out my steering column needs to be replaced the motor is shorting out for the power steering ~ certain models of malibu's 2005 yr if your vin falls between 5F100001 - 5F250216 call Chevrolet they have a Technical Service Bulletin # 07126 - SPECIAL COVERAGE ADJUSTMENT - LOSS OF POWER STEERING ASSIST - 7 yrs or 70,000 miles regardless of ownership - they will cover the cost of the repair ~ Chevrolet 1-800-630-2438 or
1-800-833-2438 - They saved me from having to pay out of pocket !!!
