| Diesel Fuel System problems |
While driving, large amount of smoke came out. Took it to gm dealer who said that it the fuel injectors were leaking. Looked online and noticed hundreds of reports of the same action. GMC apparently did an extended warranty for the issue, but only covered it for 7 years from time of purchase and up to 200,000 miles. Talked to local dealer who denied the service and gm wont replace the fuel injectors.
The vehicle leaked diesel fuel from the engine. The engine ran hot, which combined with the fuel leak, could result in a fire.
