Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

After having a new water coolant pump (the fourth one in my Mariner hybrid) and a new throttle body being put into my car by a Ford dealership, my car is still having the same problems. Now a "service emission sys" warning has come on, and being under 150,000 miles still I contacted Ford to see what could be done since it was "fixed" by them but still has a problem related to the electrical hybrid powertrain, and Ford says there is nothing else that can be done, even though it clearly is under the warranty that they created due to the failures of both parts.

On December 30, 2006 my car stalled and the dash error message referred to a mecp pump. I had that part replaced with an amazon part before the recall, it is also faulty.the safety recall is, 142S19, from Ford. Cars stall because of a faulty mecp part. I tried having the part replaced by a Ford dealer. The dealer refused and to make matters worse they posted online that they made the replacement. That is a lie. Ford customer tried to get the dealer to cooperate but they told they cannot make a dealer honor a recall. Please help.

I was going down the expressway when I got a warning and a message telling me to safely stop the vehicle, and I lost power down to a crawl. I took it to the dealer and they said this wasn't covered by the extended warranty I purchased even though they said it was part of the power train.I even called Ford customer service warranty division and they said it wasn't covered but if it was recalled they would refund repairs with receipt.. I looked online and there are lots of complaints of this part going bad and replaced by a updated version that will hold up better for this gas/ele. Motor. I believe they should recall this part and cover it upon replacement. The cost estimate was $670!

Car would not move at all after coming to a stop when making a left turn in the middle of an busy intersection. With the car idling at 1000 rpms, it would not move when I pressed the accelerator. I had to shut the vehicle down completely, restart it, and then it would move forward only if I pressed the accelerator immediately after restarting. If traffic did not allow immediate travel, the car would not move forward as previously described. If you could not proceed immediately this cycle would continue multiple times. This has happened on over 30 separate occasions with this vehicle. This problem caused multiple safety risks from side or rear end collisions.

On I-66W vehicle lost engine power at highway speed. Displayed stop safely now and master vehicle electrical hazard warning lamp. The incident was extremely harrowing for the driver as the power cutoff was unexpected and immediate. Coasted to shoulder. A restart, per the owner manual, was attempted but did not work. Transported on flatbed to Ford dealership. Dealership stated hybrid battery harness, hybrid cooling fans, and throttle body needed to be replaced and PCM reprogrammed for $1900 to ¿¿fix issue. Owner requested a new 12V front battery and warning ceased. Owner decided to do some research and test drive short distances. On 5/24 the engine cut off in an office parking lot. Vehicle was able to be restarted and go 4 miles back to residence after the carpet covering the hybrid battery was pulled up and the cabin A/C turned to high in an effort to cool the battery area (it did not feel hot but the owner believed if a temp reading was the cause a few degrees cooler might help). A wealth of info was found indicating this was a known problem and had multiple Ford technical service bulletins issued (09-18-6 Sep 09 hybrid systems - red triangle on/dtc P0A27 set¿). the owner compiled a list of 88 complaint numbers on the NHTSA site that indicate substantially similar experiences from 2005-2008 Ford escape hybrid / Mercury Mariner hybrid owners. Believe root cause is a design flaw in the PCM S/w that removes engine power when a minor deviation from the nominal battery temp range is sensed. Likely contributing issue is a poorly designed hybrid battery cooling system (battery harness, battery cooling fans, mec pump, blend door, relays). The NHTSA is urged to open an investigation into the stop safely now/master vehicle electrical hazard engine shutdowns. Vehicle is not repaired and can be made available for inspection.
