The instrument panel cluster will stop working. No gauges, speedometer, or tachometer. Usually occurs after vehicle has been driven, turned off and restarted. Know of several people having/had the same issue with this year model. Sometimes the cluster will become active again while driving, but usually doesn't.

My whole dashboard stops working the gauges lights everything just stopped working. I was traveling down interstate and everything stopped working but after a few seconds it all came back on for about 30 seconds and it all shut off again and never came back on I made it home and turned the truck off and went inside. I got up the next morning to go to work and cranked the truck and no gauges or lights were not working still. I slammed my hand down on top of the dashboard and everything came on and was working but that didn't last long and everything shut off again.

Radio speakers went out while still under warranty. Dealer tinkered with but never found exact problem and have not worked properly since. Then left rear door ajar indicator came on while driving 4 years ago still doesn't work most of the time. Fuel gauge inop. 2 yrs ago. Then speedometer erratic since august last year. And since oct 2013 vehicle just dies at low rpms or idles erratic. One out of 53 days most everything. Works fine except fuel gauge. Then all of sudden all the problems come back. I have been told it is all probably caused by the instrument cluster but with the it being over the mileage for the extended warranty nothing can be done and since just swapping out the instrument cluster may not fix any of the problems I should just live with it.

Instrument cluster has continued to fail. Called local chevy dealer, because truck is over the mileage it is no longer covered by recall that I was not informed of. First oil pressure gauge quit then speedometer failed. Chevy has known of the problem and should be held accountable to fix this problem.

While driving at any speed, I hear a chime from the instrument panel, then notice that the vehicle can no longer accelerate. I also notice that the engine light is on, and there is a message displayed stating the vehicle is in "low engine power mode". At this point, the vehicle can still be driven but at very low speed only. Any power for maneuverability under heavy traffic or highway conditions is gone. After pulling over to the side of the road and shutting off the engine, the engine light stays on but the engine power may have returned to normal (for a while). The following day or so - the engine light may even stay off, and everything appears normal. When the problem is first noticed, it seems to recur every few days. As time goes on however (maybe 2 weeks) the problem happens more frequently and is less apt to "reset" just by turning off the engine. The first time I took the vehicle into the dealer, they replaced the throttle control sensor connector, for a total bill of about $350. Now, after only 10 month, the problem has recurred. I took it back to the dealer yesterday, after only two of these "events" within one week, and was charged another $535 to have the throttle body replaced ("faulty sensors within the body"). Last night the problem came back again (yes - same day!). Today the dealer added a "redundant" ground to the throttle body (no charge this time). I was told by the mechanic that this problem has shown up on many vehicles like mine, and that gm seems to be at a loss as to what is causing the problem. This is an electronic throttle control (no direct linkage between gas pedal and carburetor). I am thankful that gm designed this to fail with power loss rather than full power (toyota), but I believe this is a safety concern none the less. Gm is obviously aware of the problem but is doing nothing to repair an obvious design flaw in their product.
