20000 mi Black sooty buildup at exhaust pipe tips. Dealer said this is normal. Our other car, with a turbocharged engine alos, does not have any evidence of soot at the tail pipe. After driving ~ 15-20 minutes to get to interstate, exhaust smokes so you can't see out the rearview mirror accelerating onto the freeway in cold weather. Dealer says this is normal. Car hesitates or misses, occaisionally when driving 35-40 mph in 3rd gear, cruise on or not. They reflashed the engine contol module. It helped decrease the frequency, but did not eliminate the problem.
