I have been experiencing. Severe hesitation and loss of power. I have replaced the 3 ignition coils, the ignition module, new spark plugs, and a wire set. I have been reading alot about fires on this site. Yesterday 7/7/16 when I came home there was a loud weering sound, and once I turned off the engine their was a loud piercing whistle as if built up pressure was being relieved under the hood near the passenger side wheel well. Today again a lack of power, flashing service engine light, and no power. I afraid the engine might catch on fire as in other postings on this site.

While entering the interstate highway, car started losing power at 50mph. After getting car up to a safe speed, got the car home where it then stopped running and would not re-start. Mechanic checked and found that the head gasket failed at 130,000 miles. This car has always been well maintained. Nearly caused me to be rear-ended as I was on a70mph interstate highway! Also, your website keeps telling me I have an "invalid VIN number!" this is the only one ever issued for this vehicle. What's with this?

My 2004 buick lesabre keeps losing power while I am driving. This is the 4th incident in 2 months! The vehicle dies and the power steering locks. This is a dangerous situation as I was on hwy 190 and there is major work being done. I was driving over a bridge and their are barriers on both sides of the highway. Each time the incident occurs I get a crank but no start. My vehicle is then towed to a mechanic and I've been told that the crank shaft sensor and ignition module are bad. The sensor has been replaced twice within a weeks time and not three weeks after the module was replaced it is back at the shop today. I have no leverage under texas lemon laws because it is used vehicle and unfortunately I have to put my job before my safety because I have responsibilities. I am in a dangerous situation right now!

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.

While driving on a 40mph road, the engine spontaneously lost power - the power steering and brakes also ceased to function as a result. The radio and lights were still on. After guiding the stricken car to a safe area, I turned the engine back on and was able to drive as normal. The issue repeated roughly a week later at lower speed while going over a speed-hump in a shopping center parking lot. Note: the issue occurred following the addition of apartment and mail keys to the keyring. I separated the additional keys from the car's key following the second incident. The issue has not repeated since.

Bought a used (2 owner) buick lesabre in dec '08 having 37,428 . In early march, '09, after less than 4000 miles, started hearing a brief gurgling when engine turned off. In mid-march, while pulling onto a highway from a slight upward grade the vehicle lost power, and a drive train vibration took place for a few seconds....nearly causing an oncoming truck to collide with us.took vehicle into a national franchised transmission dealer for checkup...transmission checked ok. However, technician discovered radiator fluid in manifold intake area. Suspecting leaking intake manifold seal and/or cracked intake manifold cover. Need to use the vehicle, but have to wait for repair until money can be put together. Am a disabled ex marine,vietnam vet.. Shouldn't have to put up with this problem, especially when it looks like a very prevalent one ,based on what is on the net. Replacement part is only 140.00 through a national parts company. The auto shops are quoting over 800.00 to fix. C'mon, let's get something done about this before someone is killed!!! Haven't you noticed the power failures in some of the reports??I would think gm would do a volunteer recall, rather than risk reputation, and consumer life&limb. The problem is that gm was using havelin's 'orange' antifreeze (dextrol) and it was faulty. It was congealing in the engine, disrupting coolant flow, thereby causing overheating enough to blow intake manifolds and/or gaskets........seems the 8 auto tech's I've talked to over the past week know this. So, why don't the industry and gov."experts"???

Tl*the contact owns a 2000 buick lesabre. The vehicle has bridgestone insignia sl, size p/205/75/r15 tires. While driving 65 MPH, the contact heard a strange sound coming from the vehicle and the engine began to lose power. He pulled to the side of the road and had the vehicle towed to a local auto shop. A professional technician noticed that the tread from the passenger side tire had completely separated from the tire. As a result, the tread from the tire became trapped underneath the vehicle, which damaged the engine and fuel pump system. The vehicle is currently being repaired at the cost of $1,900. The contact has pictures of the failed tire. The failure mileage was 28,000. Updated 05/29/08.
