My warranty (2002) is 5yr/100k on the engine and engine related componets. Injectors on the 01's and 02's are 7yr/200k. Most everything else is 3yr/36k which includes the tranny, differential, axel seals etc etc. Tires / batteries are generally covered by manufactures warranty. There are some exceptions that I'm not sure of but paint for example is rarely warranted for more then a year and smog related stuff has a warranty which I am unclear on. The NSBU sw that tells the ecm what gear the trans is in seem to fall under the emmisions warranty for a diesel.......So making a short story long, 3/36 is the end for most items other then engine
