Speedometer don't work,gas gauge don't work, transmission is going out etc and i only had the vehicle for 9 months now but the problems have been for along time. *tr
Speedometer failed at 44,000 miles. gas gauge misreads. instrument cluster is being replace by gmc on other models with the same cluster but they decided not to replace the envoys cluster. gmc knows that they have clusters that fail and have even been monetary reimbursement by other companies to replace but still do not replace for the envoys. *tr
Took vehicle in for inspection and check engine soon light was on. a code p0455 was found which means a large gas leak. it was discovered that the gas leak from the gas tank seal where the filler neck hose attaches. repair is replace fuel tank as the filler neck is built into the gas tank. *tr
