2002 GMC DENALI User Comment / Complaint

At 34,000 miles it started with a squeaking noise under the truck when moving. dealership could not find a problem. noise continued. individual found that the "plastic parts" used in the universal joint were broken up inside. replacement parts consisted of the same plastic parts which are in need of replacement now at 62,000 miles. service departments are not fully knowledgeable of the denahli system or its parts and spend more time ordering the wrong parts. also the engine has cut out on me while driving. luckly i was traveling at less than 15 miles an hour. on top of everything else today the muffler has a hole, the size of a nickle, rusted out of it and condensation water shooting everywhere. this truck has been nothing but trouble. high priced truck, low quality parts. repairs are in the process.
