Buick LaCrosse Problem Report
Buick LaCrosse The Check Engine Light With Code: P0011, P0014, P0021, P0024, P0341, P0346, P0336, and/or P0391
Vehicles with certain V6 engines may illuminate the Check Engine Light one or more of the following codes: P0011, P0014, P0021, P0024, P0341, P0346, P0336, or P0391. Our technicians tell us that some vehicles may require a powertrain control module (PCM) software update to correct this issue. Other vehicles may have excess camshaft end play on one or both cylinder heads which will need to be corrected using special procedures outlined by GM.
Light constantly coming on with the same misfire codes. I looked at my mechanics little computer and one of the four manufacturer codes was the P0011 codes. - Visitor
Car idles when at a light. Upon accelerating check engine light comes on and car loses all power. Had it towed to the dealer 2 times and dealer has been unable to replicate the problem. Upgraded software, recommended using different gasoline and changed the fuel pump after the first incident. Issue has not re-occurred "yet" but dealer recommended trading it in and getting a new one. Which is not an option since i would not want to buy another GM vehicle based on this experience.
Update: Experienced the problem again. Dealer unable to replicate the problem. Now also experiencing replace battery in the key fob. Replaced battery but car would not recognize the fob. Removed cup holder and employed the manual process for starting the car. Replaced battery again and reprogrammed the key fob. Fob now working to unlock car, and when in the car have only experienced two intermittent issues where car will not start. Never EVER have I experienced these problems with a car that is less than 5 years old. GM, your product needs to improve if you ever want repeat customers. This gal, will not purchase another GM vehicle again. Looking to trade this in and find a more reliable mode of transportation. - MSullivan10

On two occasions the check engine light has come on suddenly...and remained on. On both occasions, the car was towed to the dealership who advised me that "sometimes computers have to be adjusted." There remains other troubling problems, which may or may not be attributed to this symptom, e.g. car has shut off completely when making hard left turns, car has surged unexpectedly when applying brakes, etc. - disgusted1
