I have had issues with my vehicle's oil leaking then burning/smoking off my car. This issue is on my engine's manifold & hasn't been recalled even though the same engine is recalled on other GM models. The engine on my Lesabre is the same 3.8 liter v6 3800 engine that was recalled twice by GM in the past 6 years. My engine had minimal fire in the incidents I experienced but quite a bit of smoke from the area the oil leaks. Once I kill the engine the smoke stops. GM wants to charge for a diagnostic check & wouldn't recognize the issue on the very same engine, viewing it as just a vehicle not recalled even if it has the same faulty part. It caused my car's catalytic converter to fail as it burned through. A fix is costly, so I went to my own independent mechanic to save myself money since GM does not want to take care of issues that they recalled. …

Beginning about August of 2015 until now, oct 2015, the engine of my Buick le sabre has begun to stop running while driving. When that occurs I lose my power steering and power brakes. Tonight (oct 7, 2015) it happened four times on the way home. I made it home safely fortunately but I will not drive the car again until it is fixed. Last week I had both a mobile mechanic and an auto shop (purcell) look at it and they can not diagnose the problem. They call it an intermittent defect. What I have experienced sounds exactly like the description of the experience of the automobiles that GM has recalled, although my year, make, and model are not on the list that I found on the internet. My experience is so similar that I want my ignition switch replaced by GM before I will drive the car again. Please advise. Thanks.

The 2002 Buick Lesabre has the same engine as the 2000 Pontiac grand prix, which is covered in the recent recall 15V701. This recall covers oil leaking from the manifold onto the rest of the engine, leading to a risk of fire. The 2002 Buick Lesabre is, however, not officially covered in recall 15V701, even though mine definitely shows all the symptoms of the recall. I have already taken it to the shop once to try to correct the problem. I would like to see the 2002 Buick Lesabre covered under this recall. If not, please outline why. Also, what is the exact fix for the other cars that are covered (because I would like to have that information when I take the car to the shop again to try to correct the issue; I again have oil leaking from the top of the engine)?
