Four problems related to suspension have been reported for the 1999 Buick Lesabre. The most recently reported issues are listed below.
As I was driving from the gas station I took a left and as I accelerated, the engine started to vibrate. I I had never noticed this before that day. So proceed to take my time carefully back to work. I examined the undercarriage of my 99 Lesabre custom and that's where I noticed that the drivers side subframe bushings have all but fell out due to severe rust. Thankfully the passenger side is still firmly attached. Upon further research, this is a common problem with gm cars of this era and the dorman replacement parts are readily available. Had this component failed on both sides the engine and transmission would have fallen out and caused an accident or worse. I am still trying to figure out if this is a recall issue or just a bad choice of vehicle design by gm and their lack of concern for the publics well being. These subframe bushings should have been or should be a viable recall concern today. Thank you for your consideration in this matter.
Suspension is not working properly. Vehicle becomes unstable/ bouncing, and moving from side to side to the point where consumer is getting sick. Contacted dealer, and the dealer is not willing to do anything.
When traveling over 60 mph the steering wheel moves too easily. The dealer/manufacturer acknowledges that there has been a change in the suspension starting with the 1996 models.
When vehicle rides rides over a bump or a series of bumps not readily visible, the bounces are above normal and in a series of bumps directional control becomes serious.
