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.

Traveling about 65 - 70 mph I noticed my speedometer went 'wacky', meaning it went down to 0 - 20 mph and back up again to the speed I was traveling. Nothing else happened. The next time, maybe a week to a couple weeks later it did I it again, only I heard the doors unlock and it had died. Since then it has been happening more frequently. I have always been able to start it right back up. I can be out on the highway or in town. I usually put it into neutral, start it and keep going. It has happened as many times as 3 times a day, or it won't die for 3-4 days. I did have one especially dangerous situation with a semi-trailer truck behind me on the highway when the vehicle just died.

In approx 2010 my Buick Lesabre had issues starting and would occasionally stop operating during travel. All ignition functions would cease to work. Towed to Buick dealership to resolve and replaced ignition switch. This year a similar action happened where the car would not start. Again at the dealership the ignition switch was replaced. Is this ignition switch issue included in the GM recall?
