Power Steering Reservoir Going Down

Heads up. I have an early 14 and love it. It takes the Pentosin CHF-11S or whatever FCA calls theirs which is in fact Pentosin. I took it in about April as my reservoir was low and I topped it off to the blue line before doing so. Mistake as the dealership which is first rate could not find a leak anyplace. I paid the fee for them investing it and stating no leaks anyplace. Must be evaporating as others have reported the same thing. I raised the BS flag stating I have a 07 BMW 335 that takes the same Pentosin and in 10 years of ownership I have never seen the level go down.
It is low again so I am at a decision point; should I just refill it myself (48,000 miles) and just ignore this until it gets worse or take it into the dealership and see if they can find a leak? I was told by my dealership that they could top it off if they can't find a leak. Here is the deal. I pay 139 bucks diagnostic fee regardless if they find anything or not. I have Max Care but it only covers the repair and they argued last time that I had to pay the maintenance fee not the 100 bucks which Max Care says should be paid before the service program kicks in.

My thoughts until I can see something really leaking it is doing the same as last time but leaking a little more now. I would guess I will add 6-8 oz of Pentosin and keep watching it. Once it really starts leaking where I can notice something pulling the fiber cover off the bottom the dealership can then repair it.

Be sure to check your level and use the FCA MOPAR power steering product or Pentosin CHF-11S. When I checked MOPAR had a better price than the parts houses or ordering online...

Re: Power Steering Reservoir Going Down

Your problem sounds very much like what happens here on other threads. Most of the time the steering rack is slightly leaking.

Re: Power Steering Reservoir Going Down

Looked at my PSF yesterday and it was 3/4" below the minimum mark. I have 2015 JGC Limited Ecodiesel with 13,300 miles


I visually could not see any wet spots on the R&P boots or anywhere underneath the engine compartment. No fluid on the garage floor.


Took it in this morning and the dealer looked at it. They pulled the lower shield and didn't find anything wet or leaking. They topped off the fluid to the max line.


I'll keep an eye on it over the next couple of months and see what happens. If it goes down again it seems to me the leak has to be on the rack seals and the fluid is sitting inside the boots.


Dealer told me if fluid was sitting inside the boots they would swell up and deform and get soft.


Time will tell.

Re: Power Steering Reservoir Going Down

I think until they see it dripping on the floor they will do nothing. Makes sense can't see it must be just an owner with no clue. So far I have lost well over 12-14 oz since I have refilled it twice. My service plan is good until 8/120 so I have time. I might squeeze the boots and see if anything weeps out...

Re: Power Steering Reservoir Going Down

If it goes down again I will insist they check inside the boots. I also have the 8/120 extended warranty.


I don't think it was low from the factory when new. This topping off will tell the story if there is a issue.


You're right, they think we are imagining things. At least it's documented now.

Re: Power Steering Reservoir Going Down

My level was right at the blue line. I refilled to a line slightly above that I marked slightly above the blue line. I have a good dealership but frustrated with this issue. I have replaced power steering racks by myself so I know the score...

Re: Power Steering Reservoir Going Down

Experiencing the same thing with my 2015 Limited with 20K miles. Mine seems to get to the minimum mark and hasn't seem to go below that. I'm thinking that may be because it sits for extended periods of time without being used. I'm not noticing any leak indications as well. Dealer says it wasn't top off at the factory, doubtful. I think I would have caught that on delivery inspection.

Power Steering Reservoir Going Down

Mine has also done this since new with no visible signs of leaking. I have a bottle of the special fluid, forget the specification, for our Jeeps and just top it off every 10k.

For comparison, every BMW I've owned did this too.

Re: Power Steering Reservoir Going Down

Every BMW I have owned that leaked I replaced the racks on. But of the 12 I owned including some for 11 years they didn't leak.
It is definitely leaking and soon it should show especially if I squeeze hell out of a CV boot.

Re: Power Steering Reservoir Going Down

My level is low too. Looks to be a common problem or a characteristic of the vehicle. I too have the 8/120 warranty, so I am not going to worry about it. I see no leaks either. I will have the dealer top it off at the next oil change.

Re: Power Steering Reservoir Going Down

This should not be a issue with a $50K vehicle. Either it's leaking, or it's not. If it's not, the fluid should be staying at the normal level.


In the 30+ cars I've owned over my lifetime, this has never happened till the JGC.


My wife's 2013 Ford Escape Titanium has kept it's level since I've owned it.


To have to top off with 6-8 oz. of PSF in a year is not normal. Till I saw this post it wasn't even on my radar that this was a issue.


If I hadn't checked it, in another 6 months it would have completely lost all the fluid.


Again, it was 3/4" below the minimum line. I'm not accepting that this is just the way it is. There is a issue and FCA and the dealer should and will in my case, figure it out.

Re: Power Steering Reservoir Going Down

I have had this issue with my '14 since the day I bought it. The service advisor at the dealer said that it is normal to consume some fluid. This is the same guy that told me I used out of date DEF when he looked at the shipping date on the container instead of the the manufactured date. So much BS. I am in the middle of a Lemon Law claim now--going to arbitration in March. Too many troubles with this vehicle!
