Unhappy Check Engine + Red Triangle + "Problem" displayed on Nav

Hello, I'm new here and hoping someone can help me.

This afternoon my Check Engine and Red Triangle lights came on, along with a very helpful "Problem" displayed on the navigator. It does not say anything else, not does it actually tell me what the "problem" is.

The car's a 2005 which has worked great up until now. Even when I drove it home from where I was the car seemed to be working just fine.

I live in the California desert, where it's currently 110F, could that be the problem?

Should I take it to the dealership? Or is this something that I could try to fix myself?

Any advice you can give would be extremely helpful.

Thanks a lot.

There have been several Prius's with similar problems in the past couple of weeks. Suggest you read the following thread:

Also, it would be helpful to know how many miles you have on the odometer, and whether you have had any maintenance or repairs performed in the past few days or weeks. If so, what was done?

In addition, have you replaced any of the following; and if so, when:

• Traction (high-voltage) battery

• 12-volt battery

• Hybrid coolant pump

The information above will help members provide more accurate troubleshooting advice.

Thanks, and WELCOME to PriusOnline!
