A boss I had several decades ago sued GM regarding his lemon Chevy and won. Just about everything that could be wrong about a build was evident in his car, which he was only able to use some two months out of the 18 months he owned it - the rest of the time GM was trying to fix the problems. Cooling system, engine blowup, tranny blowup, rear-end blowup, paint and body problems, etc. One problem was leaks in the roof, water would cascade down on him after a rainy day when he parked. They opened the ceiling and found a wrench inside, from the factory when the car was built. After winning his lawsuit, my boss vowed to never again own an American car.
