Have a 2012 Prius with 210k miles and what looks like the original traction battery I have a trip planned from NJ to FL in August. A little worried about a failure that might strand me along the way. I have zero issues so far. MPG is generally good. No coolant leakage or excessive oil consumption. I drive gently but I have only driven the car for its last 20k miles any suggestions for increasing my chances of no issues. I just cleaned the battery fan. It wasn’t too dirty. I also cleaned the eGR cooler and replaced the water pump last summer any recommendations for a dr Prius test?
I would not worry about the hybrid battery stranding you. They usually don't suddenly fail especially at highway speeds. Hopefully no codes. If you have had a rough start I would think twice about the trip. Primarily due to the potential of an early head gasket leak that is not yet showing coolant loss. Too many clean their egr thinking it will eliminate an occasional start up rattle. I would keep the speed down to posted limits and I would want an engine temperature monitor which could be a bluetooth app like Car Scanner or whatever you have assuming you can easily see it with a phone mount.
