Get you car inspected today. Do not drive until it is
Plastic intake manifold failed at 110,000 miles, replaced that. Ran good again.
Now the subframe rubber bushings have failed, and almost left me stranded. If the final bolt had broken, it would have disconnected the steering wheel and I would have had no control on where I was headed.
This is a major safety issue that can easily be inspected by any owner, no special tools needed (other than a flashlight if it's dark).
How to inspect: Look under the car directly behind each front wheel. You will see a subframe assembly bolted to the floor of the car with two bolts on driver's side, and two on the passenger side. These bolts go up thru a large round washer-like retainer for the four inch diameter rubber bushing that fits inside the subframe.
What you want to look for is if the washer under the bolt head is rusted and/or the rubber bushing is in good shape. Three of the four on mine were completely gone. Parts are available from the dealer to replace these. The rubber parts are called insulators.
I am not sure what years and models are affected by these, but I found numerous reports from other year LeSabres. It may be as widespread as 1991 - 1999. I believe any "M" body style could have this problem.
Would you buy another car from this manufacturer? No
