Power Steering Pump Warranty Extension

[__raj]

While fishing for the torque convertor warranty extension I ran across the following TSB for power steering warranty extension.

how are you finding this stuff, the last entry on that post is a 2011 TSB?

Educated guess on file name based on one for 2012 that works from elsewhere. It is sequential so I simply kept adding one in filename.

The files for 2012 are: http://techinfo.honda.com/rjanisis/pubs/SB/B12-0XX.pdf

where xx=01 for first one.......xx=31 equals last one I found.

I thought that's what you were doing. Although I was able to open the ones from that thread last night, today I'm getting a link Denied message.

My power steering barely works at slow speeds. Is it normally hard to turn? My wife drove it the other day and she hasn't driven it much. The first comment she made is that she could hardly turn it.

BACKGROUND
On some 2007–10 MDXs, the power steering pump
does not provide the intended amount of assistance
while the vehicle is driven at slow speeds with low
engine RPM, making the steering wheel hard to turn
when driving in areas such as a parking lot. To
increase client confidence, American Honda is
extending the warranty on the power steering pump in
affected vehicles to 7 years from the original date of
purchase or 100,000 miles, whichever comes first.
The warranty extension does not apply to any vehicle
that has ever been declared a total loss or sold for
salvage by a financial institution or insurer, or has a
branded or similar title under any state’s law.

If you believe your steering wheel is hard to turn at low
speeds with low engine RPM, call any authorized
Acura dealer and make an appointment to have your
vehicle inspected. If the hard steering is related to the
power steering pump not providing enough assistance,
the power steering pump will be replaced at no cost.
Please plan to leave your vehicle for half a day to allow
the dealer flexibility in scheduling.

Got the letter from Acura Canada. Pump being replaced now. Except brakes and rotors needed work and the bill is going to be larger than I would like for an A service! doh!

Well, also updating the Torque Converter software requires tranny fluid flush. Software update is free but tranny flush is NOT. Another doh!

[Dominik-X]

Lucky me, I did a 3x Drain and refill meself 2k miles ago. They should not require me to do that again. Although I see no mention on the TSB of the update also needing a tranny flush

[dapretendr]

so the links don't work, should i just call my local dealer and call to see if my vin qualify?

my pump does vibrate a bit when reversing out of a parking lot. but its not like i can't turn it like a car with no power steering.

Update: The tranny fluid flush wasn't due to software update. Tranny fluid was just dirty and needed it. Also gives the best chance for tranny to be as smooth as possible after update.

Software update. This feels more like the version prior to last years update. Higher RPM's before the next gear. Espeically 5th gear. Prior to today, 5th gear was hit during 65kmph-70kmph causing judder since RPM was only at 1300 or so. Now, it changes from 4th to 5th at 80kmph or so and rpm is at 1500. Makes a big difference. Anecdotal but I feel higher RPM gear changes overall. Just like prior to my first software update over a year ago. Back and forth with software to try and fix this darn judder issue. Smooth now, tranny flush probably helped.

Power steering, much smoother during parking now. Also asked tech to replace o-ring but he said it was part of the replacement kit.

Love the smoothness now. Except for the slight pulsing even after machining front rotors. Got near front brakes as well. Might go after market rotors all around when rear pads need replacing. Always something to improve upon!

btw, the rumbling of the power steering got worst over time (ie. turning wheel when stationary). Now, it's pretty much gone!

I went in yesterday to pick up the tranny fluid. I did a synthetic oil change yesterday, doing the tranny flush today and doing brakes and rotors all around in a couple of weeks.

I asked the service department about the TSB on the power steering and he said it was open on my VIN. I also asked about the torque converter and he said no. Would be helpful to get a copy of the TSBs that are out. I am going on vacation for a week and he said to call when I get back and schedule service for the power steering. He said it would take about an hour and if it needed it then they would order the pump and I would have to schedule the actual service then.

X owners...How many miles you had when you first noticed the power steering problem?

[Yumitori]

Make sure the tires are properly inflated. See the driver’s doorjamb label for more information.

With the vehicle on the ground, start the engine, and warm it up to normal operating temperature.

Warm up the power steering (P/S) fluid by letting the engine idle with the transmission in P, and turn the steering wheel from lock to lock about 20 times.
NOTE: If you do not heat up the P/S fluid, your diagnosis may not be correct.

After the P/S fluid is warmed up, turn the steering wheel from lock to lock, and note the steering
wheel effort.

Continue turning the wheel from lock to lock, and raise the engine RPM to between 1,500 and 2,000.
Note the steering wheel effort and compare it with the steering effort when the engine is idling.

If the steering wheel is easier to turn at high RPM, then you might be effected.

If the steering wheel effort at idle and high RPM is about the same, this bulletin might not apply.

There was a night and day difference when I did this test. I’m going in Saturday to have this fix done.

That is a good test Yumitori. The best part about getting a new power steering pump, the darn vibration (which got worst as the car aged) during steering while stationary is ALL GONE! Let's hope it stays that way.
