2005 Hummer H2 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

DOES NOT MOVE PAST 1.WHEN I ACCELERATE NEITHER OF THE TWO GAUGES ARE FUNCTIONING. I HAVE YET TO REPAIR IT BC IT HAS HAPPENED JUST A FEW DAYS AGO BUT I WAS TOLD THAT I AM LOOKING AT A VERY LARGE REPAIR COST TO REPLACE THE ENTIRE DASHBOARD CLUSTER.
