High Temperature Warning

A strange / worrisome thing has happened to me three times now, and I wanted to see if anyone else has had the same problem.

My coolant temp spikes, I get a high temp warning, and then the temp drops back to normal. This all happens within a 15 second window. It happened under different driving conditions each time, so I am really confused. I've checked everything, and it all seems normal under the hood.

I did a forum search and it came up with one guy with similar problems, but it had to do with his engine block heater. There’s not much use for those in Houston… 104 the last few days.

Im in Houston as well, and haven't had any issues with this heat. Trip to dealer is in order. Have you checked for dtc codes?

I'd just run it down to the dealer to have it looked at. I imagine that should leave some kind of code in the system they could see.

The coolant cant physically heat up and cool down in such a short period of time so it sounds like a faulty temp sensor. Should be an easy fix for the dealer.

Agreed.

It's better than overheating.

Could also be your thermostat sticking too.. Go to the dealer on this issue soon.
