my 09 chevy hhr is doing crazy stuff at random
Ive had it sine july 2018. Its used..
But lately as i drive it reads low fuel, but there is a full tank of gas. Then it says to service tire monitor. Then evrything goes back normal. Continue driving then car interior lights go off. Is this a bad BCM anyone please give me a starting point. No codes come up when it was scanned . The car does not stall jerk ride hard or funny
just gauges randomly go crazy

Moved to a new thread

The starting point is to ask if the recall has been done? .https://my.chevrolet.com/recalls

Check the battery.

Then check out the fuse boxes.

Then check out the connectors on the ECM.

Most likely would be low battery voltage, possibly a dead cell in the battery.
loose fuse panel under the hood.
a loose ground wire.
loose fuses, relays, or connections

Another vote for checking the battery. After sitting for a while (10+ minutes) it should read 12.6 volts or higher. Any lower and the battery should be replaced.

Come back and let us know what happens!

And welcome!
