Specific symptoms reported on the 2006 Mercury Mariner
Recalls 3
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.
Recall number 15V606000 · Recall details
Hybrid propulsion system
- What is wrong
- Ford Motor Company (Ford) is recalling certain model year 2005-2008 Ford Escape hybrid electric vehicles manufactured October 13, 2003, to June 20, 2008, and 2006-2008 Mercury Mariner hybrid electric vehicles manufactured June 10, 2005, to June 20, 2008. The coolant pump for the hybrid system may fail resulting in the hybrid electronics overheating.
- Risk
- If the hybrid electronics system overheats, it may shut down the powertrain, resulting in a stall-like condition, increasing the risk of a crash.
- Remedy
- Ford will notify owners, and dealers will inspect and replace the original Motor Electronics Coolant (MEC) Pump with an improved brushless pump, free of charge. The recall is expected to begin on October 27, 2014. Owners may contact Ford customer service at 1‑866‑436‑7332. Ford's number for this recall is 14S19.
Recall number 14V526000 · Recall details
Visibility: windshield wiper/washer: motor
- What is wrong
- On certain trucks, passenger cars and sport utility vehicles, the windshield wiper motor may have been produced without grease being applied to the output shaft gear.
- Risk
- After a period of continuous use on the high speed setting, lack of grease on the output shaft gear may cause the gear to distort or fracture during operation resulting in a loss of wiper function. Inoperative wipers under inclement weather conditions could cause a crash due to impaired visibility.
- Remedy
- Dealers will inspect the wiper motor for the presence of grease and grease the wiper motor gears if necessary. The recall began on november 22, 2005. Owners may contact ford at 1‑800‑392‑3673 or lincoln/mercury at 1‑800‑521‑4140.

What 2006 Mercury Mariner owners say
Most recent owner complaints, unedited.
As I am driving down the road, on a city street. The vehicle will just shut off, for no apparent reason. It does this several times. Every time the car is been driven it will shut off several times and me and my family have been in traffic when this has occurred. It continues to do this at any speed and every time the car is driven. Can't drive the car not even a mile before it totally shuts off.
Tl* the contact called on behalf of his daughter who owns a 2006 mercury mariner. The contact stated that after his daughter turned into a parking lot driving approximately 15 -20 MPH, the vehicle collapsed without warning on the front passenger's side. The contact managed to veer to the shoulder of the road out of the way of other vehicles. A towing company was contacted and the vehicle was towed to an independent mechanic. The technician inspected the vehicle and noticed that the subframe and cv-joint were fracture. The vehicle was not repaired. The contact mentioned the federal safety agency campaign number: 14v165000 (structure) as a possible solution to the failure however, the VIN was not included. The contact also stated that the federal safety agency campaign number: 15e045000 (suspension) was replaced approximately 1 year ago, after the wheel collapsed on front driver's side. The vehicle was also repaired by an independent mechanic. The manufacturer was not made aware of the failure. The failure mileage was approximately 190,000.
Engine suddenly cuts off while driving. Message on dash says to safely stop the vehicle.
Recall for coolant pump on hybrid system could result in hybrid electronic overheating causing a stall like condition recall was addressed by dealership back on 7/20/2015 2nd owner has had vehicle for 9 mnths - have had 3 incidents of vehicle shutting down with dash light advising to pull over for safety and the system shutting down directly after - brakes /steering etc. For the first incident - towed to local dealership - unable to diagnose 2nd incident - to a reputable local mechanics shop - changed out normal vehicle battery 3rd incident - caused driver to roll through an intersection on a red light - struck by other vehicle
The gear shift is not properly shifting. It goes from park to reverse on its own. Sometime it wont reverse and makes a loud noise. It click back and forth between gears. Ive replace the switch to see if that would work but it doesnt. Please let me know if I can do anything to fix this problem but it is the same recall 15v606000 for other vehicals of the same type
While deiving a message on the dash stated to stop while it is safe. The car proceded to stall. It could not be started. I happen to be in the middle of the road and required to call for help to push the vehicle to the side. I was able to start the car later that day to drive it home. This is the forth time it happened over an 18 month period. I was very lucky that I was not in heavy traffic or on a high speed road during any of these events. I did have the car to a repair shop after the last time it happened and described the problem to the mchanic. Repairs were made but nothing to do with this problem. This is definitely a safety issue and it appears that it has been reported many times. I do not understand why there has not been a recall on this issue. I don't know what to do at this time or whether I should continue using the vehicle.
The car shuts down on the freeway while driving at 60-70 MPH. A red triangla is displayed along with a message, pull over stop safely now. This has occurred several times after driving g approxamately 30 miles. Luckily I was able to pull over safely. The car restarts within 30 seconds and will shut down again every 5 mins until the vehicle is allowed to cool down.
I was driving on the turnpike and my car suddenly dint turn when I turned the steering. Me and my passengers somehow escaped the life threatening situation in the middle of the traffic. It was my cars sub frame that was rusted so bad that it broke in the middle of the road. This is after I service my car every now and then. Its a serious issue with this car and there should be a recall for this problem. I had to spend so much due to this carelessness from the company.
My vehicle: 2006 mercury mariner hybrid SUV. Purchased new in 2006. In hot weather...vehicle engine quits while in motion on freeway at approximately 70 MPH (3 times), and city streets (3 times). Extremely dangerous when engine quits while driving on freeway in traffic. All you can do (while praying!) is coast to a stop and do your best to pull off on to shoulder of road without crashing into other vehicles. We have tried 3 times to get ford motor to repair this problem...all to no avail. The last time we had to pay approximately $1,500. However, ford motor did reimburse us! But at the same time they claimed the problem was resolved. Not true! About two years later the problem started all over again. For10 years we have been driving a defective vehicle that was--at all times--a danger to our lives. Ford motor should have taken this problem much more seriously and either replaced the vehicle with a another one, or truly fixed the problem. I feel ford motor has liability in this matter. The last time this problem occurred was july 16, 2017.
