#2 of 51 2005 Buick Lesabre

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?

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, find a dealer who does. This adjusts for the uneveness in the tire's rolling height when under pressure. In other words, many tires don't roll round; even if they're balanced they crush differently on one part than another under the car's weight. So they essentially roll as if they are not round.
Park Avenue and some LeSAbres and Sevilles went to Michelin tires (Symmetry) to get away from tire imperfection. The company swapped tires on Park AVenues to put on Michelins to fix the problem.
Also, the wheel alignment affected my 03 with 16 wheels and Michelin symmetrys that it came with. I had a good service manager who used the vibration analyzer to be sure it was wheel and tire speed related. I told him that after he had really carefully balanced them, it seemed to oscillate on uphill pulls but not ont he downhill pulls o smooth interstate in Tennessee. He felt the alignment wear on tires and took it in. The rear were out of toe and the front also. He set them to what he considered the middle even though they were within tolerance. GM paid for alignment touchup up to 12000 miles. So get back with alignment complaint andget them to print it out. Also do Force Balancing.
Fixed it. Ain't perfect, but no car is. They stayed balanced until 35K and I paid to have them rebalance $7.50 each.
What tires were on the car and what ones did you replace with?

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.

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.

Thanks Imadazol97, I don't know why Buick would drop the cabin air filter. Really keeps the interior cleaner. I'm asking my dealer for a holder.

I have a 2004 Buick LeSabre with the same problem. I have been to the dealer again and again. Sometimes they tell us we are nuts, there is no problem; sometimes an honest technician says, yeah, this car has that problem and we don't know how to fix it. They have even tried new Michelin tires. I have initiated a Lemon Law complaint with our state attorney general's office. BBB Autoline (Better Business Bureau) has a website that can help you get started. I would encourage you to stick it out; I test drove a used Buick before purchasing mine and it's vibration was even worse - probably a testament of what is to come. Unfortunately I had no idea this was a consistent problem with the LeSabre, or I never would have bought mine. Good luck.

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?

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.

FWIW, Michelin Harmonys stopped the vibration in mine. I love these tires. Quiet, good traction, great ride. Had them on 1.5 years and 21K miles.
