 The catalytic converter caused the car engine to turn off in the middle of the road. the car was having acceleration problems getting to just 25-30 mph and while driving it, the engine turned off and took several attempts to restart it. after a couple months, i found online that letters (special policy number 05551) were supposedly sent out to impala owners for an extended warranty for this faulty part. i'm the second owner of this car so i wasn't aware of this and just got it replaced in october. a chevy district specialist said the car was bought 18 days before this warranty coverage and i was 2 years outside of it because i'm the second owner. the car is in great condition and less than 84,000 miles on it as of today. i'm not sure what warrants a recall, but several sites have customers saying they've had to replace this part multiple times on their cars because gm sold a car with a faulty design. *tr
