Weird stuff in hot weather

[Rickb3825]

So I moved to Las Vegas. And when it's really hot, in the triple digits. My truck does some strange things. Let's say it's lunch time and I go grab a fast food feast. I'm then sitting in the parking lot eating, listening to the radio, running the truck at idle and enjoying the AC. After a few minutes the emergency flashers start going. Today, I was distracted by a phone call. And suddenly my horn honked once. This got my attention and I saw my emergency flashers were blinking. It was a good thing because I was running late. The other thing that happens in the afternoon is the power center, where the usb ports are, have no power. I have a Motorola dongle that connects my phone for Android Auto wirelessly doesn't work. After about 15 minutes of driving it starts working again. Has anyone else experienced anything like this?

Batteries don't last long in the heat. If yours is a few years old, a new battery and making sure all of your ground wires have a good connection would be the place to start.

I have that issue with my radio when it's really hot

Its probably a bad battery I have lived here in the phoenix area for over 20 years batteries only last 2 years 3 if your lucky

It’s related to the TPMS fill alert. My 22 does it too. Sitting still idling in hot weather causes the front tires to experience a rise in PSI from heat. Engine heat plus parking lot surface temperatures cause this increase in PSI. If the system senses too much of a rise in PSI it will trigger the fill alert.

The fill alert may be/can be?? disabled I’m not sure, I’ve never looked into it. I’ve only had it happen when having my lunch in the truck so I just shut the engine off and restart to reset it.

It's not a given that everyone has a fill alert. I do not have it. When I picked up my truck at the dealer the pressure was ~90 PSI in each tire, which is 10 PSI over max sidewall pressure and I received no alert.

I'll agree with that. I'm about an hour SW of you and it actually cooled off to 109 yesterday.

Are you sure yours isn’t deactivated?

I have no way to turn it On or Off, as there is nothing in my Settings regarding the TPMS either way. I do know that I have a 'Low Pressure' alert because it has gone off before. And that picture is of a UConnect system that is several steps above mine.

That and gremlins is always my fallback.

I would agree probably a bad battery. Also, maybe a loose ground. I would also check the alternator at different times to make sure it is putting out the correct voltage.

Nice for this time of the year. I heard this weekend 116

Ding ding ding ding, you win. I realized that the day after I posted this. It occurred to me that the other thing that happens when this does is the evic display between the gauges goes to tire pressure. Still don't understand why that power station doesn't work. But it's not a big deal.
