~100K miles, never any problems, what maintenance should I do?

Is that 'brake thumping' at tire rotation rate (pads or rotors) or ABS system thumping (pump)?

In another year or so, may want to look at changing brake fluid, transmission fluid.

Otherwise, repeat the 10k+ intervals.

 

No.
My mechanic quotes $90 parts and labor, about $40 is parts.

There are a number of youtube videos for a gen3, and the v is the same.

This guy is clearly not an expert, yet does a fine job.

 

The guy's a larcenous idiot. That's putting it politely.

I've drained/refilled the transaxle fluid myself, a couple of times now. It takes me maybe a couple of hours, mainly due to the time to raise and level the car just with floor jack and safety stands. The fluid (4 liters on hand, about 3.5 needed) will cost about $40 at the dealership parts counter.

 

So is that brake thumping or tire thumping? Pulsing through pedal?

 

Yes, you have a bad rotor. It may have been that way since new, but it will continue to worsen. Whether it can be remedied depends on how far out of whack it is, which is justification for dealing with it sooner rather than later. Tire changing gorillas can do that sometimes when they use an air wrench to over-tighten lug nuts out of sequence and warp the rotor.

 

I watched a Costco mechanic torquing wheel nuts: no star pattern, just go around in a circle.

 

Tranny Fluid change takes less then a 1/2 hour, and should cost no more then $100.00. Find yourself another mechanic.

 

Warped (out of flat plane), not out of round. They warp for a variety of reasons including out of tolerance (too thin), and over-tightening of lug nuts. Honda rotors are THE WORST for this.

 

The rotors are like a big washer: drop onto the lug bolts, then wheel, then the lug nuts.

 

Just hit 100K on my 2012 Prius v. Replaced the spark plugs with Bosch iridium. Big difference, engine smoother and mileage improved. Highly recommended.
Will do the 10k oil service and radiator and inverter coolant flush per service manual. The dealer does not recommend the transaxle / transmission flush. They said it is a sealed unit and they can only flush 4 quarts. I plan to keep the car for another 100k miles. Any thoughts?
Thanks.

 

Makes no sense. It's in no way "sealed"; there's a fill and a drain bolt. There is no point to a "flush", and full capacity of the transaxle is around 4 quarts; when you drain it, yup, maybe 3.5 quarts'll come out. If you've got four quarts on hand that'll do you: just refill with the car level, till it starts coming back out, which will occur around 3.5.

 

Replaced my trans fluid at the dealer a couple of weeks ago, took about a 1/2 hour and $100.00 bucks. Your dealer/service advisor needs to go back to Toyota school.

 

The quoted me $220 in NJ. I will probably get the fluid and take it to a local shop.

 

The alos quoted me $159 for coolant flush and $59 for the oil change? Is this the going rate?

 

This is the transaxle fluid change? Yeah still too high.

Get 4 quarts of "TOYOTA ATF WS" from Toyota dealership parts department, and ideally also get the two washers (one for drain, one for fill, they're identical). Print out the instruction I posted, it'll help whoever you use. The parts are around $40, and for a garage with a lift it will take about 1/2 hour. If you're providing all the parts, they shouldn't charge over $50.

Is this a Toyota shop? And even they might not be that familiar with Prius coolant change. There's two coolant circuits on the Prius, one for engine, one for inverter. Watch NutzAboutBolts videos, pinned in the maintenance sub-forum, just to get an idea of what's involved. Again, use only the Toyota spec'd fluid, to be safe.

 

Can somebody please confirm, at 100k do you need both the engine and inverter coolant flushed? There are two separate systems, right?
Thanks.
