hfl stays connected to my phone after shut off, plus tpms error( went away for now). this all happened today. my town has been raining heavily for the last 5 days. is this electrical problem. any possible DIY fix? im afraid my car will go off randomly in the parking lot at work tomorrow. my car is 2006 with 136k miles.

 

It's normal for the HFL to stay connected for a minute or two after you've shut the car off. Check your tire pressure.

 

Check your battery....low battery voltage or a bad battery will cause alarm to go off

 

I would make sure the skylight drains are clear and water isnt getting on your cpu given the rain and the multiple issues

 

The car was back to normal agin the next day. Something prob got wet from the rain. Thanks for the inputs
