I'm planning to drive my 2005 Prius with 175k miles from Bozeman Montana to Anchorage Alaska on the Alcan highway in late April, and I want to make sure I take care of any needed maintenance now, where I have access mechanics. I want to minimize my chance of having any trouble miles from anywhere in Yukon territory! I bought my prius with 145k miles from a mechanic/dealer specializing in hybrids, so it had been thouroughly checked over and fixed up before I bought it. Since then, I have not had to do any major repairs. The car has been very reliable, but is starting to show it's age (mileage is closer to 45mph, runs a little loud). - what parts/maintenance tasks should I make sure get checked and attended to for a Prius this age, and considering I will be driving through places FAR from any repair shops? - should I take it to the Toyota dealer, or try to find an independent shop that does well with hybrids? And how would I even go about finding a good independent shop? In the past I've had repairs take longer/be more expensive than necessary cause a mechanic was not really familiar with hybrids and I would want to avoid that. - I have a chilton's manual, so I'm open to advice on what things I can save money on by checking myself and what things I should let a shop handle. I'm fine doing basic things like fluid changes and 12V battery changes but don't know enough about cars to tackle serious repairs. I already know that I should get a full sized spare tire and air compressor.
