I have a very heavy steering, when im parking in my garage and moving the steering wheel from left to right or right to left i hear this hissing noise inside the cabin. But when i open the hood and try looking at the power steering hose while moving the steering left and right i see the hose moving also and hear that hissing noise as well. What could it be? its not a squeek its more like air hissing.

Also what i noticed recently is when i turn on the car, hot or cold my rpms flactuate when i turn on the ac and the car stutters a little but then when i also engage into drive, sometimes it stutters to the point i feel like it could die one me. wonder whats going on here. The rpms also drop lets say when i go into reverse and brake, the rpms drop also. Seems like an IDLE problem.

I dont notice antything while driving.

 

I'll help you best as possible here. If anything we can meet up and ill take a look.

A few things can be happening here. Steering hard while not moving, when raise up the RPM's and turn the wheel in which it feels better then that's a p/s pump issuse. When there is noise present while turning the wheel usually indicates a leak with low fluid present which will also effect steering effort. Most common of the leaks is the p/s hose which connects to the top of the pump, if you didn't get that replaced under the recall then they tend to leak. Right by your oil filter on the cradle itself is the lower p/s link which has a 10mm clamp to secure the rubber to steel line. They tend to be loose and start a very small leak.

There is the p/s cooler lines that run behind the front bumper, right side where your lower grill pieces are which also has another 10mm clamp to secure the rubber to steel line. Those tend to loosen with time and start a small leak. The least likely to fail in these vehicles but still a possible, is the p/s rack. The fluid can leak out of the rack itself and flow into the tie-rod boots. Sometimes you can see the fluid leaking out of the boots, but sometimes you need to poke a small hole in the boots to see if they are leaking. One or both sides of the rack may leak. The lines going into the rack may also leak.

But 1st thing 1st, you start with the most obvious and pull off the cover where your washer fluid is and check your p/s condition and level. If it's black you need a p/s flush service, if it's low you have a leak present. Acura uses a clear with a slight hint of yellow p/s fluid. Most other companys uses ATF or a red type of fluid.

How to tell if you have the orignal p/s hose and not the recall one... Simple, the recall hose has an aluminum sleeve towards your rear valve cover and has a thick rubber sleeve towards the top of the line going to the p/s pump. The orginal hose doesn't fit that discription. Ive noticed all your running condition isssues with the vehicle my honest suggestion to you is either sell your TL and get another TL or get another vehicle in general.

You know with the the heat waves we've had your vehicle will suffer in the performance department. Hot humid air mixed with the already boiling hot engine bay doesn't allow great performance. You will suffer not only low end but all around. Vibrations you feel with A/C on ect may just be your motor mounts are toast. A/C does kick the RPM's up to take care of the extra load and the RPM's will drop down once the compressor kicks off. This cycle will continue as long as you have A/C on and will also vary in time to kick on and off compressor all depending on your fan speed and temp settings.

As others have suggested you need to scan your vehicle for codes, not only PGM-FI (ECU) but also VSA-ABS/Traction as well as body electrical. Your VSA/ABS/Traction have a huge role in how your vehicle is going to perform. The system is designed to keep you safe, it will also cut or reduce your power to the wheels if deemed unsafe. The slow low-end pick up, yeah VSA has much to do with the traction and power to the wheels.

 

Since your local and it seems like you know what you doing and we met once on the parking lot, next to the starbucks when i was with my fiance looking at your car so you know who i am... Im thinking you could help me out here I dont even know where to go and who to trust to take care of this problem. When you come back from your trip i hope you have some time to take a look at my car and see it that feels normal to you.

thanx a lot man

 

I hope I know what I'm doing since I work for Acura

Ive been doing Automotive Technician work for 7 years now. Been with Acura for 8 months. Thank you, like I said we live right next to each other so it's no biggy for me to look at it.

 

This sounds like his best best for his issues his car has. I hope you can help him out with these issues he has.

But back to your PS issue, what's the fluid level and how is the coloring?

 

Ill pay you whatever it takes if you can find the culprit... seems lilke Im only able to spin tires when its raining outside Not that i would want to but just bothers me that a car with all the modes i have done cant even do that ...

 

The fluid is right on the low level line i gotta see the color better but seems pretty dark to me.

 

Ok today i checked the power steering fluid reservoir when i heard the noise again. With the car running i opened up the cap of the reservoir and saw some foaming or boiling or bubbling, whichever describes it the best. What is the sign of that ?

 

Guys i have the same thing but i don't hear any hissing noise coming. Only thing is the heavy steering problem.

 

anyone who can help me please

 

need more info like how much fluid is in there, call model/year, the exact problem, etc.

 

I also have this problem without the rpm/stutter issue. A mechanic told me that the fluid was dark and have a burnt smell to it. The PS fluid level is fine and the recall was done as well. Also have a smell coming from under the car.

 

if its foaming/bubbling then you have a air pocket that is in your power steering system. more than likily it the the o-ring like on this video from youtube.

I had the hard steering issue while stopped or near stopped. I had the recall done and they replaced the o-ring. I still had the issue so I replaced the power steering pump with a remanufactured one from O'Reilly Auto Parts and the problem was fixed. It was $94 and only took my 1 hour to replace.

I actually had gotten so used to the hard steering, I didn't know how bad it . I started the car and turned the wheels. I actually thought the TL was on jack stands because it turned so easily, but it wasn't, that is just how easy it is supposed to be.

 

omg i would be so happy if my TL's power steering gets to be that soft seriously!. I have to use both of my hands to actually be able to parallel park.

 

Judging by your signature, you have a Kinetic Blue TL-S! The TL-S comes with a "tighter" steering system so its a bit harder to move the steering wheel. It's good in a sense because it provides a good amount of feedback to the driver! Systems like the new electric ones don't provide much feedback however they are easy to spin and turn!

 

dude i really have to put a lot of strength when turning though. I've driven other TLs including type-s and they're so much softer. I actually feel like if im working out when im parking lol

 

Sounds like a bad P/S pump if there is no leak or air in the system this would be the case. If you have warranty left take it to the dealer

 

Now look at the mods i have below as my sig. Do you think my warranty would get voided if they see that? That's 1 reason why I'm scared to take it as it is even though i know my warranty is still good until November of this year.

 

Your misinformed, only and only if whatever modification you did cause the failure will that item NOT be covered under warranty, your whole vehicle as a whole will still have warranty. Understood? Take it to the dealership.

 

I just got back from the dealership and got my power steering wheel pump, the resovoir, the 2 side mirrors, and a side marker replaced for free! I don't even have to struggle to park with 1 one hand

Acura of Westchester is one to go!

 

bad o-ring if there are bubbles and its dirty

 

My car (05 tl) had a "whining/droning" noise in winter that had the tough steering symptom. I know on my car it was a recalled hose or something for the power steering.

2 years ago my steering was making a funky noise. Dealer replaced PS pump and boned me for about 400 bucks. About sixs months ago I noticed steering was really stiff. Dealer checked for leaks but found none.

Then last week my engine light came on, VSA light came on and tranny would not shift out of 4th (up or down). I was freaked out so as soon as I got off the Tappan Zee bridge I stopped to check trans fluid (it was fine).

When I restarted the vehicle, VSA light went out and trans was shifting ok. Turns out the throttle sensor was bad. Had sensor replaced, codes have been reset and all is well. Steering now seems better. Makes sense since it is variable assist steering and faulty throttle sensor probably distorts reported speed.

 

I looked at OP's vehicle two weeks ago. I found the his p/s 0-ring for the inlet hose was not replaced. So I replaced it with the updated 0-ring, and check the rest of the lines for any leaks. The 2x 10mm clamps that lead to the cooler and rack were slightly loose so I tighten them both up and filled up the p/s fluid. Other than that a system scan cleared codes, rotated tires and off he went. I haven't heard anything bad so I'm sure it fixed his steering issues.
