Hello,
I have conflicting opinions on why my gas gauge and tire pressure lights are acting up. I had the fuel tank sensor replaced.
That didn't help. I was told by an Infinity dealer that it's the instrument cluster. Now my TPMS flickers and then stays on. My mechanic told me all four were working properly and that it was the battery. I think he is just trying to sell me a battery. The dealer did state that all the indicator lights will start acting up and that this is a sign that it's the instrument cluster. Thoughts anyone?

TPMS lights don't flicker. Sounds like the internal power supply in your cluster is dying.
