My 2005 Impala speedometer and temperature gauge are working when they want to. I set the cruise controll at 70 mph and car seems to do fine. I dont use the cruise controll and try to hold the car at 70 mph and got a ticket for doing 82 in a 65. After getting the ticket on 12 March the speedometer after either 20 minutes of sitting or driving does not read right says below zero, then I turn car off and on to try and reset the guages work on and off.

Speedometer stops working or shows a lower speed than actual speed. This occurs at least once a week, sometimes more often. So far has not caused an crash, yet.

The speedometer is at 35 mph when the car is at a standstill. The indicated speed is incorrect when the car is moving, showing a faster speed than the car is moving.

I have a 2005 Chevy Impala, currently with 22,320 miles. At my oil change and tire rotation, (~20,500) I was informed by repair place that they would not perform the tire rotation as I would be needing to replace the tires soon. I asked why they were wearing so fast- I was told, they noticed it on many Impala- premature tire wear between 18,000-25,000 miles. ~ 15 months ago, with only about 13,000 miles, when I had an oil change done I was informed me the engine was leaking oil from the rear of the engine, I should take it to the dealer for repair. The dealer had to replace (under warranty) several seals/gaskets- oil pan, drain plug, oil filter, plus replace the drain plug. The car is sometimes hard to start and have to hold the key in the start position, and/or lightly press the gas pedal to start it. About two weeks ago, I grinded the starter. Sometimes the car will start roughly and immediately stall, or will stall the first few seconds as I am backing out the drive way. Dealer about this they told me I was using cheap gas and to use a better brand, but I always use "brand" gas, I even use fuel injector cleaner dealer later told me I needed to have the fuel injection "flushed" with their system for $199, plus tax and charges, hearing it was not good for the vehicle, I declined. I have also noticed a "clunking/bumping/banging" noise when turning, especially hard turns. My brakes need to be replaced, the front brakes are starting to make a thump when braking, and yesterday when braking hard, I heard a squeal noise, (rear?). fuel gauge sometimes rapidly fluctuates, when driving, and at times when accelerating, (though not concurrent) I hear a "swoosh/gargling" sound. I was accelerating too hard. The fuel gauge will swing as much as a 1/4 tank when driving before recovering to the correct position. Gauge shows low fuel level, low fuel light comes on, I only needed 10-12 gals to fill it (~16 gals).

Speed sensor went bad at 45,000 miles on a 2005 Impala. Repaired the problem and found it caused the instrument control panel to be in-operable and need to replace that. Wipers also park in upright position. No defect codes found.
