1999 Buick Lesabre problems

Filed Apr 16, 2019 · Suspension · IN

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.

I was sitting at a red light when my air bag from the steering column deployed in my face. I did not hit anything. It was on or about 1/25/18. About a week prior to this event my horn began to steadily blow inexplicably. I did not have any reason to suspect anything other than a malfunctioning horn so I disconnected the wires to the horn. When the air bag deployed about a week later I concluded the air bag was inflating inside the steering wheel applying pressure to the horn sensor. I took it to the dealer who, after weeks of investigation, concluded they could not do anything to repair it and suggested I call general motors customer assist center. After reviewing pictures, (no one actually physically looked at it) gm decided corrosion to the sensing module caused the problem. I contend they have a defective valve which overtime began leaking gas into the air bag, hence the issue with the blowing horn.

1999 buick lesabre. Consumer writes in regards to defective ignition switch- anti theft wiring issues. *smd the consumer stated the ignition switch had to be replaced. An examination revealed that one of the anti-theft wires was broken and the second wire had the protective insulation coating cracked through to the copper wire. It appeared that rotation of the cylinder had chafed over time and compromised the integrity of both wires and the cause the security dash light to illuminate and the vehicle not to start.

My car is a 1999 buick la sabre with a 3.8l engine. July/20/2012 my car had 80,000 miles on it when my engine started to miss. When I got it looked at by my friend I was told there was coolant in the cylinders. The engine had problems with the intake plenum leaking coolant, because of the egr system. He then fixed the car. On november 20, 2014 my engine had 138,000 miles when it overheated on the highway. I found no coolant in the reservoir with coolant in the oil. When my friend looked at my car he said it was the plenum again, but this time the coolant in the oil may have wiped the main bearings. The overheating may have also warped the cylinder heads. He told me at the least there was damage done to the bearings. Being upset I looked online for information to find that this problem is common with that engine. Also that gm didn't acknowledge the problem. Has gm finally admitted to faulty manufacturing? Even if my car is fixed I no longer feel safe driving it. It may leave me on the road in winter someday with my young son. Or worse, stalling on the highway with loss of power steering. Can someone please help? I am a single mother going to college and money is tight.
