My vehicle was towed to the dealership on 10 april,2003, the catalytic converter/ exhaust system had to be replaced, my car doesn't even have 47,000 miles on it and it is just barely 2 years old???? The engine lost all power, the parts were replaced, the transmission was flushed, but.... The vehicle still doesn't have the power that it should have and the transmission is not shifting like it should, now I was told that when the catalytic converter went that it sent pieces though the lines in the car, I did ask the dealer if this would be cause a problem with the engine or the transmission and the response was (it shouldn't) now this does sound like a problem to me.... I would like someone to look into this matter and give me a real answer on this problem...the problem that this vehicle had is kind of unheard of in the early stage of mileage and age.. The dealership was even confused on the problem, all computers that the car was placed on by different shops should nothing was wrong with the car, until it was put on a flat bed and taken to the dealer.... I would appreciate any help you can give me in this matter....
Vehicle is 2001 chevrolet impala. At 11,500 miles, engine began to lose coolant. (no visible leaks). Dealer service manager indicated "this is a big problem" and that plastic intake manifolds on gm v6 engines are warping causing coolant loss. Dealer "fix" was to install "gm pellets" to seal cooling system. If engine still loses coolant, intake manifold will need to be replaced (approx cost=$800). According to various interntet chat groups, this problem exists among a wide range of gm models with 3.4 and 3.8 liter engines, yet there is no recall or any written acknowledgement from gm that this problem exists. There is also no indication that replacement of the intake manifold will cure the problem, as the replacement part is identical to the original.
