Example complaints
Engine cooling: “We own a 2002 Denali, that we bought used. The transmission went out around nov. 2008 (appr. 120,000 miles) we had the transmission replaced but the transmission went out again shortly thereafter (around 150,000). Through civil litigation, we found out that the transmission had went out previously, at around 70,000 miles. We are wondering if this is a common problem with denalis and if any compensation is available.”
NHTSA complaint #10282600, filed 2009-09, 70,000 milesTransmission and drivetrain: “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. …”
