Intermittent Vibration/Shuddering -Prius v (lowercase v for the Prius v wagon)

Dry CV joint?

 

Rotate the wheels and see if it changes. Tires can do weird things, and a defect in one will change how it feels if you rotate.

 

I had that in an old Datsun pick-up, I tried everything, wheel alignment, balancing, u-joints, and it was the tires themselves...tread squirm in an harmonic..Google ...death wobble.

 

Tread separations can do that too.

 

No, my wobble was intermittent, only started at a certain speed or after hitting a bump. It did not do it all the time, it was hard to track down. But through the process of elimination, weeks of time and money, it boiled down to the simplest thing...the tires. The tires looked good and balanced well, but the wobble only stopped after changing the tires.

 

Incorrect. A defective tire can do almost anything. Rotate and see what it does.

 

Try cleaning the mass air-flow sensor and the thermistor next to it. Use a spefific MAF cleaner aerosol. Do not touch the MAF sensor resistors. Do not use the MAF in car until it is 100% dry. With MAF cleaner, wait 30 minutes for cleaning solution to evaporate.

Might work. Had similar issue and this sorted out the problem.

 

probably close to new tyre time anyway.

 

I bought the $79.00 code reader to record data on my Gen II . Well worth it to get access to all the sensor data and not just the idiot lights. My money is on tires though.


iPhone ?

 

Still, no harm in cleaning the MAF. Something that is overlooked on services. It caused intermittent lumpiness and some intermittent vibration. The poor ECU was being lied to on how much air was entering the engine. Finally after a few weeks caused a P0172.

The mechanic-in-a-can cost me slightly less than £8.

 

Could have been a rock temporarily lodged in the tread, just enough weight to throw it out of dynamic balance.

 

My prius v 2013 has 155000 miles. I just had this problem for the dirt time today, that's why I got into this user blog.

The thing I that I had this issue when I was parked, not moving. It seemed that the problem started when the gas engine got started.

The tire response is inaccurate, because the problem is intermittent, not constant.

I thought it could be a failure on some kind of rely that triggers the gas engine to turn on.

I'll appreciate any advice on this issue. Thanks...

 

It is possible to get a bad shutter at startup if the engine is not properly running and synced with the hybrid's cvt and valve timing. I have had it happen on an older prius where I simply shutoff the engine and started again and everything was normal. These cars have variable valve timing and stepped rpm engine operation that is all synced by computers and the cvt transmission in conjunction with the cvt's electric motors. But if it does not throw a code / set the check engine light, I would not worry too much. Some people would suggest the 12v battery might be weakening.

 

Hello! Are found the problem? I have the same issue at 128,600 miles on Prius v 2013
