Specific symptoms reported on the 2005 Mercury Mariner
Recalls 2
Power train: automatic transmission: lever and linkage: floor shift
- 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.

I was driving on the freeway and my car just quit working. I took it to the mechanic and the issue is the coils and a now fried computer system.
As of monday oct 23rd 2017. My 2005 mercury mariner started stuttering, hesitating, losing power, spitting, suffering, how every you would put it. When you push on the gas. It did this off an on this day. Later this day it felt like someone pressed on the brakes and then floored the gas at the same time. When this happened the anti-theft light flashed at the same time it done this. It does it with in about 10 seconds then the light goes out and goes back to spitting an sputtering and the radio volume goes down and back up off an on as this is happening. It continued doing all of that every so often everyday from oct 23rd - oct 31st. On oct 31st 2017 I was coming home, it was around 9:30 p.m. Speed limit was 55 I was running right at 60 coming over hiwassee bridge and my hole vehicle shut down had no light inside or out wasn't running, couldn't steer, tried to turn hazard lights on to let cars coming both ways I was there but nothing would work. My boy friend said I'm going to put it in neutral he reached over to see if it would crank nothing I started getting nervous so I just put it back in drive and after a couple seconds it was running again but had no lights at all inside or out just could drive. So I was trying to make it to the end of the bridge with no lights so I could pull off but it started acting going crazy flashing on off like it was possessed or something. It did that for about a minute the the head lights came on and stayed on just the head lights only still had no other lights no tail, brake, or inside lights, just head lights. So I tried to make it on home. It continued to do the spitting an sputtering thing and the battery light flashed on then off about 3 times in 5 miles my turn was coming up to the left so I just tired the blinker hoping it will work, no luck. After I made the left turn got going the hazard lights came on. 7 miles all lights on.
On the freeway and car suddenly has overdrive light blinking, at the same time I began losing power, I was able to get off freeway but not after I open hood and nearly got run over. I was checking to see if there was overheating or smoke. But nothing. I have already replaced PCM, transmission, and torque converter. Consequently my shifter is broken and you can see down into transmission. Obviously no I can't drive, I will have to have vehicle towed. Why hasn't transmission been recalled on this vehicle. I could not think about if my child would have been with me and stood in front of car. He never would have been able to move that quickly or even worse with freeway driving I even could have been hit from behind.
My 2005 mercury mariner premier has a problem when driving that the left and right door shows they are ajar. And it cycles back and forth across the dash board, you hear a beep then the message is displayed on the dashboard . When the car is parked and locked the alarm goes off between five and 10 times a night draining the battery. This has started about a year and half ago. I took my car into a ford dealership on september 27,20016 to be repaired. I had the car in their car care for two and one half weeks only to find out that the part for the right side the cable and handle assembly is recalled and there is no replacement at this time and no estimated time frame for it to be available. I spent $544.00 on a rental and $604.39. I still do not have the problem fixed and ford dealer says it has no time estimate when it can be repaired if any?
I purchased a 2005 mercury mariner on 2/14/13 from a local dealer in my area. Within two days the vehicle broke down on me. I did not purchase the warranty (stupid mistake) but I did take the vehicle back to the dealership in which they assured me they would fix the problem. It was a transmission problem fast forward to 03/2015 the transmission went out in the vehicle which cost me around $3,000. That is more than I owe on the vehicle, would not recommend this vehicle unless you want to pay for it twice.
