What is wrong
Ford Motor Company (Ford) is recalling certain model year 2001-2008 Ford Escape and Mercury Mariner vehicles manufactured March 31, 2001, to September 1, 2009. The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015. These service repair part transmissions have a shift lever bolt that may not be properly tightened. As a result, the shift control lever could disengage from the transmission without warning.
Risk
If the shift lever disengages from the transmission, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the gear selection indicator may show that the transmission is in the "PARK" position, but the vehicle transmission may not actually be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Remedy
Ford will notify owners, and dealers will inspect the transmissions and either tighten the manual shift lever bolt or replace the manual shift lever assembly. These repairs will be performed free of charge. The recall began on October 23, 2015. Owners may contact Ford customer service at 1‑866‑436‑7332. Ford's number for this recall is 15S28.

My power steering went out while I was driving. I took this vehicle to my mechanic and he said that it was related to the power steering recall they did on this type of car. But when I put in my VIN it said this car was not recalled. So I am wondering if you guys skipped over my vehicle. I would appreciate if you would look into this. Thank you.

The car is reving high and accelerating poorly. Then the red triangle light telling me to stop safety now comes on causing me to pull over and shut car off. I turn the car back on and it drives but with same issues. Look on the carcomplaint.com website for tsb-09-19-12 and tsb-08-24-5 which detail what my car is doing and makes it appear like there is a cooling pump recall. Ford just told me there are no recalls listed for my VIN though. The frequency of which the red triangle light comes on is increasing this month. It was every few months and now it is weekly-daily.

Ford's recall "code 14s19" on 2005-2008 mariner hybrids and escape hybrids should cover all of these hybrids but it has exceptions! Ford has issued a recall on *some* of the 2005-2008 ford escape hybrids and *some* of the corresponding mercury mariner hybrids. However they are refusing to issue a recall on my particular 2008 mariner hybrid (which is exhibiting the electronic overheating problem described in the recall where the stop safely now comes on and there is an immediate loss of power). They are refusing to fix my mariner just because the VIN number does not match the particular manufacturing lot covered by the original ford recall - though my SUV does fall in the date range mentioned in the recall) I am certain this recall should cover more hybrid SUV than ford has admitted to, and since the mariners had a very limited production run, it is less likely that there wil be a significant number of complaints due to this very serious life threatening issue - and I would like to emphasize that there have been numerous complaints about this including on the federal safety agency. Ford should expand this recall to include all defective ford escapes and mariner hybrids before serious accidents start occurring as a result of vehicles shutting off during operation because of either drive electronics over heating due to a bad coolant pump, (and possibly other causes?). ----relevant recall-- the federal safety agency vehicle safety recalls recall number 14v526000 recall date 09/03/2014 component hybrid propulsion system ford contact number for recalls 1‑866‑436‑7332.
