This car began to show signs of front end wobble a few months ago. This means it feels like the wheels shake from side to side mostly when accelerating from 30 to 45 mph. I took it to the dealer about a month ago but he said he only felt it one time while driving it several blocks around the dealership neighborhood. I took it to Firestone immediately after I left the dealership and they balanced the Bridgestone tires and the wobble seemed to be lessened. I then took it home and replaced the rear rotors and brake pads as they seems to vibrate when we put the parking brake on while driving. This seemed to help smooth it out at the time. This is my wife's car so she drives it and in less than a month she said it is wobbling again. I drove it again tonight and it is much worse than before so I believe there is something seriously wrong with this suspension. This car has been under a warranty from warranty warehouse for the past seven years and we have had some repairs made at the dealer and each time we ask them to check the front end as it made grinding noises and never seemed to handle as it should. Each time the dealer said it was ok. This appears to be a problem with many reports on the internet regarding front end issues with Buick Lesabre. We also had the drivers side seat repaired under warranty and it has not worked properly since it was repaired. We have had it back for this issue at least three times.
