  What code was showing on the code reader? There's on that indicates the system can't keep pressure and that would indicate the gas cap or other hoses or switches.

  I have a 2005 Buick LeSabre custom which I bought used last week on 4/29/09, and I have had to go back 2x this week because the service engine light came on, and this time the tech told me the gas cap was defective. Car has 68,500 miles was a rental car before I bought it. Is this a common problem

  Hi, I have a water leak in my 2005 Buick Lesabre. It happens when using the air conditioning. The leak appears to be clear clean water. It's coming from under the dash on the passenger side. The dripping is approximately three inches from the floor board hump. The amount of water is enough to saturate the carpet on the passenger side. I suspect it is a problem with the drain from ...

  My Service Engine Soon Light is on. I had my nephew (mechanic) check for the code and it is EBP P0496, he tells me that the gas tank is going to have to be dropped (he can not do this job). He told me to take the car to the dealership and get the job done. How much is this going to cost me? Does anyone know?

The previous time 2007 it began shaking after driving down out of the Colorado mountains after many miles of braking...result was new rotors and brakes.

Buick LeSabre Brake Problems

  Very interesting! My son has an 05 LeSabre he inherited from his grandad. The car was brand new and made the scraping noises at 10,000 miles. I have since replaced the brakes twice, two sets of tires and now the front wheel bearing and hub need to be replaced! My daughter also has a Buick Regal that has brake issues. Is this a Buick problem??

  Written by: niceride3 on Dec 15, 2009 12:01:53 PM

  Apparently, YES it's a problem!! I have a 2003 with 78K and the cap needs to have special attention to make sure it's secure OR you WILL get a check engine light. Once the cap is secure, the warning will go away after a few start-ups. And unfortunately if the gas cap needs replaced, your Auto-Zone replacement won't work....it MUST be a GM cap. Fred

  I haven't heard that description for transmission problem. Is it an engine problem? Miles on car? Plugs wires changed in the last 60-70K miles with AC plugs and OEM level wires? Possibly a coil problem reacting to heat. Check each coil tower for cracks or tracing of spark jumping. Check bottom of coil for poor contact to base to which they bolt.

  Mys 2003 Les with cheap Goodyears has no problem, there are tsb's out there about the issue relating to this being more prevalent with the lite weight suspension components, as mentioned a road force balance is important and there is even a suggestion of replacing front hubs and bearings.Even a slight runout is felt in the car.

• Re: 2005 Buick Lesabre [shoshm]

  Written by: imidazol97 on May 1, 2006 5:29:12 PM

  Which Michelin tires were put on? Was the car aligned correctly? Has the car been driven with the vibration analyzer attached to various parts to diagnose the vibration type? Were the wheels force-balanced on Hunter 9700 by someone who knows what they're doing? Preferably a GM dealer who knows what's needed for trouble-shooting the vibrations in the stiffer frames with lighter parts in today's modern cars?

• Re: 2005 Buick Lesabre [sundog]

  Written by: imidazol97 on Jan 30, 2006 7:33:27 PM

  The filter was omitted after 02 with little fanfare. You can buy the plastic skeleton holder which snaps into the heater box and it comes with a filter. You might try aftermarket but the skeleton is probably a dealer only item. The filters are about $18? at PepBOys-Purolator.

  Wjohns02, Do you have a cabin air filter installed? Did it come with the car? I just purchased a 2005 Limited Prestige with the Celebration package, but no cabin air filter. Jim.

  Which size wheels and tires do you have? The 60 series tires tend to be stiffer. The problem is a known problem due to lack of tire quality and the lightness of the suspension parts and the rigidity of the car chassis-someone told me it's based on the original Aurora and Riveria. The tires needed to be Road Force balanced using a Hunter 9700 balancer. If your dealer doesn't have one, ... Read More

  I have a 2005 Buick Lesabre with less than 10,000 miles. The car has a consistent vibration at highway speeds even though we have tried a new set of tires and a complete rotation and balancing of the tires. The dealer indicates there is no problem with the car; however, the vibration persist. Is anyone else having this problem?

• Good-Bye LeSabre

  2005 is the last model year of the Buick LeSabre. I currently owned a LeSabre and its a very nice automobile. Its a shame GM did not invest more into the LeSabre to keep it competitive with the new Avalon, 300 and Charger full size sedans. The LeSabre was the best-selling full size car for many years and was manufactured for more than 45 years by Buick. Good-Bye LeSabre.

The LeSabre will be redesigned for 2006 (but will remain on the FWD G body platform) and get a new name and probably an optional Northstar V8.
