#1155 of 1415 Acceleration Problems by riddybear

May 30, 2008 (10:38 am)

HELP! Hi, I have a 2007 Freestyle and can not figure out what is going on with it. I have two seperate issues. The first is when I put it in reverse, it will surge then I have to slam on my brakes and the car dies and the service engine light comes on, but when I restart it, the service engine light does not stay on. When I start driving, there is absolutely no acceleration in the vehicle. The second is when I am at a stop light or sign, if I take my foot off the brake, it takes off on its own. It is incredible scary. I have read the posts and it always happens on level ground, so thats not it. On some days, when I go to start my car, I hear a load roar when I turn it on. I have 51K miles and I have an extended warranty until 60K, but Ford can't get it to do it again. They said if they can't get it to do it again, they can't fix it. I have taken it to them six times. HELP please.

It may be an issue with the transmission (CVT). When during the day and how often do the issues occur? Does it usually occur when you first start it in the morning? If so, leave it overnight at the dealer and have them test drive it first thing in the morning. It's critical they identify it within your warranty period otherwise it will cost you thousands of dollars to fix. The good thing is that it's on record that you let them know the issues within the warranty period. You may want to have it checked at a different Ford dealer.

I've been having identical problems. You are describing my 2006 Ford Freestyle perfectly. Mine started at 28,000 miles. (when I bought it) Same issues randomly stalling at any speed or in park. No bad idle or chugging. Dealer has had on and off for the last 18 months and can't find anything. The instrument cluster has been changed and a new PCM but has not fixed the issue. They cannot get it to duplicate. They had it for 2 days and nothing. I picked it up and drove 11 miles and it cut off. There is a data recorder in it now and am trying to get images. Again no trouble lights or codes. Would love to have an update on your progress. I read posts #1128 from hypnosis44 and immediately faxed the info to the Dealer. The Engine Management Module is the next thing we are going to try.

Isn't the Engine Management Module the same thing as the PCM you mentioned you already replaced? PCM stands for Powertrain Control Module, meaning it is a computer that controls the engine and transmission together.

And you can get the PCM changed for free under the emissions warranty that goes for 80,000 miles.

#1160 of 1415 2005 freestyle sunroof leak by lanbaba

Jun 14, 2008 (10:45 am)

My 05 freestyle started to leak at the sunroof area after heavy rain, and the car parked at an incline. I took a look at the leak place and notice that the water is coming out of the third row seatbelt harness area (driver side). I did some research and found out that there is a TSB out there: 07-03-6. The reason is the rear drain hose is not routed properly. Anyone know where I can find the detail about this TSB, if I want to do it myself, since it is already out of warrenty. Here are some links I found:

Yes, apparently the PCM and EMM are the same thing. I guess now we will have to move to a ground fault or bad sensor causing the issues. I was able to collect images with the data recorder that the dealer installed in my car. So, hopefully they will get a good read or some kind of error code and can correct the problem. Any other ideas or suggestions anyone can offer to this "stalling" issue are appreciated.

This almost certainly has to be the CVT transmission's problem, just hearing the evidence so far. Since problems happen when you put it in reverse, and the loud noise you sometimes hear, and the lack of acceleration sometimes, that indicates to me there is something wrong with the CVT's torque convertor clutch controls and/or hydraulics associated with that. The CVT uses a small torque convertor with a clutch to control launch from a standing start, until a direct mechanical link can be established with the CVT cones acting as continuous gearing. Also, remember that the OBDII problem codes mostly have to do with engine/emission problems, and there are no OBDII codes illuminating the way here, so it seems to indicate even more that this is a solenoid, sensor, and/or hydraulic problem in the CVT, not the engine.

#1163 of 1415 CVT Belt Tension - Fordwrench knows about this? by coldcranker

Jun 19, 2008 (3:30 pm)

Doing some research on our Freestyle ZF-designed CVT, I ran across a statement about the Mini Cooper version (a PDF file posted online that came from ZF) that said fuel economy depended somewhat on the main belt tension being correct. As an engineer myself, that makes sense to me. How is tension controlled precisely? Would Fordwrench know the answer to that? I am wondering if a CVT owner such as myself depends on a mechanic setting the tension (or hydraulic clamping force on the belt), or if there is some sort of automatic, internal method used to get just the right tension from the belt without human intervention. Is the tension set at the factory? Can it be checked? Occasionally, on Freestyle forums, someone writes about unusually low fuel economy on a CVT Freestyle, while most of us get excellent fuel economy. This may be something to look into. fordwrench, or anyone else know?
The referenced CVT article (to a similar ZF CVT on a Mini Cooper) is at Click Here for the PDF file...., page 21

#1164 of 1415 Can CVT chain tension be adjusted to help fuel economy? by coldcranker

Jun 19, 2008 (7:23 pm)

One more thing to add:
 
I communicated this question to the son of the engineer who led the original development for the basic ZF design, and he is asking his dad about this. I'll post his answer later should I get it and compare it with the brainiacs who might answer this here. I'm certainly going to learn something here, and hope you all will too.
  
From the Mini Cooper CVT transmission article PDF file to download here..., page 21
  
"Pressure is supplied to the secondary pulley to ensure that there is always adequate clamping force onto the belt for all load conditions. A solenoid valve influences the secondary pressure control valve, optimising the pressure and hence the clamping force.
Optimisation of this pressure improves fuel consumption.
The working valves in this area are the secondary valve, the exhaust secondary valve, and a PWM solenoid secondary valve."
