Overview & Reviews

All 2009 Mercury Mariner models are equipped with a new six-speed automatic transmission. The base four-cylinder engine gets a bump in displacement, power and fuel efficiency, while the optional V6 gains a useful 40 horsepower. Additionally, Ford's Sync multimedia integration system is now available, the suspension is tweaked for an improved ride and steering-wheel-mounted audio controls are standard across the board. A new Premier I4 trim level rounds out the changes for 2009.

• Comfortable interior, decent performance and fuel economy, full array of standard safety features.

• Poor braking from outdated front disc/rear drum setup, hard-to-fold rear seat.

  Bad transmission(s) - 2009 Mercury Mariner
  By 09mariner - July 2 - 11:00 pm

  Overall, the worst car weve ever owned. With 26,000 miles, its already on the second transmission, and this one is not right. Its been in the shop more than 60 days so far this year. My wife is scared to drive it, as its sometimes in the wrong gear at the worst possible time (other transmission issues too). There are others online (and in person) with transmission issues also. As nice as the other features are, none of them make up for this aweful experience. My suggestion is to wait a year for Ford to figure out the transmission before taking the plunge on this car.

  Within the first 6000 miles the transmission began to "clunk". I took it to the Dealership and was told it was a "characteristic" of the transmission. It is loud and it sometimes takes a second to "engage" and then the "clunk". I am not happy about this. The material on the drivers seat is loose and "puckered up" where I sit. I weigh 120 lbs and I am the only driver. Looks terrible! Sync is a great feature for phones but it is not compatible with my cell phone! Forget trying to figure out the Media! Even the dealersip didnt have a clue. I buy a new car every 2 years and this is the first American Car I have purchased new, wont do that again.

  Transmission problems - 2009 Mercury Mariner
  By VIC - March 1 - 10:00 am

  We bought this car in august 2009. We have taken it to the dealer in 3 different occasions for transmission problems. The first time they said they had to reprogram the computer. The second time they said they had a recall and they had to reprogram the computer again. This week we took it in again and they said they can fix the problem since they cannot reproduce the problem while testing it. This is the worst car we ever owned. The rpm jump to 6000 in the highway, the car basically stops working and you have to get out of the highway to avoid an accident. This happens randomly. Once you stop and restart the car it runs without problems. This dealer has not help us in solving the problem.

  Transmission. Seems to be the common denominator - 2009 Mercury Mariner
  By Ken - June 9 - 2:40 pm

  Our car has been garage kept, low mileage, driven smoothly. Transmission has been a nightmare. Has been to the dealership 8 times for exact same transmission issue without long term repair. They simply reset the computer. So its obviously a software problem. They deny there is a recall or even a service bulletin regarding same, even though I have found proof otherwise. Now that its out of warranty, they want to charge $175.00 each time they "reprogram " the computer. As it turns out, a FORMER service tech explained that this involves disconnecting the battery for 30 mins. Thats it! Our dealer will not stand by any one these so called repairs, and thats the real issue. No real repair, no long term fix, no support or warranty on service. Next vehicle model will be more thoroughly researched with long history of good service ratings, likely a Subaru. UPDATE: 8-16 car remains in our possession, but sadly we cant trust it for longer trips, so it stays in the garage.

  Nice Looking Car; lacks comfortable driving - 2009 Mercury Mariner
  By nikki626 - August 29 - 8:48 pm

  This car is really built nicely and it looks pretty but the drive is very forgettable. Cannot get Sync to work... will be trading in for something else.
