I have a problem with my 2001 Frontier Crew Cab SC. I bought this truck new and have had this problem repeatedly. Dealer can "reproduce" it in the shop, so it has not been fixed or diagnosed.

While driving and the truck is warm, I get an exhaust smell in the cab. Sometimes very bad. I have to turn on the AC to clear it. Also, while driving, I cannot drive with the windows open or the sunroof open because I get the exhaust in the cab.

The truck has almost 70,000 miles and is regularly maintained.

Anyone else have this problem?

Thanks for your time.
