the temperature gague said that my car was overheating, but the engine warning light never came on and i had plenty of coolant. took it to the mechanic, he couldn't find any problems other then the sensor possibly being bad. he changed that out and the gague worked fine for about 2,000 more miles & then went PAST the red line and all the way around. I found a way to reset it, but it just kept going back, so I dont even bother with it anymore.

I went on a long drive and the speedometer went crazy. Just shot up to past 100 mph and then spun around like a clock hand. Same exact thing happened to temp. gauge. Car never overheated but gauge is not working and just bounces around where ever and then stops where ever and freezes when I turn the car off. I had water pump replaced last year and have kept perfect tune ups on vehicle. I am going to try to replace sensors first.

First the speedometer worked off and on and then finally stopped with needle going all over and stopping. Then the temperature gauge finally stopped working. The Fuel Gauge still works fine. I have been told the 2005 trucks had this problem and recalled but not the 2005 Chevrolet Impala.
Speedometer only works when it wants to. Using GPS to relate to speed. Have gotten a speeding ticket due to this fault. Cannot get repaired as the Chevy dealer said it takes a few weeks and the whole instrument panel has to be removed, plus is very costly. Don't have the money to repair. DEFECTIVE!

The temperature needle goes past the red zone when I turned the engine on. This happened in the morning when the engine had been off all night and the engine is cool to the touch. I turned on and off several times then the indicator returned to its normal range

Instrument cluster has gone haywire. Sometime when I'm taking off at a light, it bumps, feels like someone has hit me from behind. Heater core went out, coolant leaks, has a small oil leak.........

Pulling the CLSTR/BCM fuse resets it; does not last more than a few days, then begins erratic behavior again.

For the last week, we've been getting what seem to be false readings on the temperature guage. Twice the needle has been in the red and other times almost that far. No warning lights have come on at all. We've replaced the thermostat, temp sensor, flushed the cooling system, bled the system, and the fans are working. It seems each time we start the car, the temperature guage needle never drops back to cold and just keeps getting higher even when the engine isn't heated up. There is nothing else indicating possible overheating or problems with head gaskets or the intake manifold. We have not found a solution yet because we don't know what's causing it.
