Review of the 2009 Mercury Mariner

  • The 2009 Mercury Mariner isn't exactly the freshest face on the block, sharing as it does a nine-year-old platform with its Ford Escape sibling. However, significant powertrain and other upgrades for 2009 help keep it broadly competitive with other compact SUVs.

  • Safety
  • Pros

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

  • Cons

    Poor braking from outdated front disc/rear drum setup, hard-to-fold rear seat.

  • What's New for 2009

    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.

What's New for 2009

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.


Nine years is an eternity in the automotive world. For many automakers, that's almost enough time for two complete model cycles. Yet the 2009 Mercury Mariner soldiers on atop a platform that's entering its ninth year of production. Fortunately, a collection of important changes for '09 should prevent this aging design from falling by the wayside.

To be fair, the Mariner has already benefited from a rejuvenation in 2008 that included new sheet metal and a revamped interior. However, no significant mechanical changes were included. Mercury has addressed this omission for 2009 by performing the impressive twofold feat of increasing engine output while also improving fuel economy, thanks in large part to a new six-speed automatic transmission that replaces the four-speed in previous Mariners. And that's not all -- the suspension has been revised for improved ride quality, and 2009 Mariners can also be equipped with Ford's exclusive Sync multimedia integration system.

Do these upgrades pull the Mariner even with the best compact SUVs? Well, yes and no. The Mariner's beefed-up engines certainly help its cause -- the 240-hp V6 is bested only by Toyota's 268-hp RAV4 and Hyundai's 242-hp Santa Fe, while the 171-hp four-cylinder unit is also class-competitive. Fuel economy likewise puts the Mariner in the thick of the compact SUV race. The front-wheel-drive four-cylinder models achieve a satisfactory 20 mpg city/28 mpg highway, while the front-wheel-drive V6 versions nearly match that at 18/26.

Additional points in the Mariner's favor include a fairly spacious cabin and secure handling, as well as the availability of the Sync system. But in other ways, the Mariner just isn't up to snuff. Most notably, its rear brakes were downgraded to inferior drums in 2008, and the '09 Mariner continues to bear this badge of shame. In our testing of a similar Escape with rear drums, the best stopping distance we could manage from 60 mph was 154 feet -- at least 25 feet longer than average, and frankly unacceptable in this day and age. The rear seats are a hassle to fold down, as the headrests must be removed and the seat cushions flipped up before the seatbacks can be folded down.

In sum, we haven't been high on this aging Mercury in recent years, but its upgrades for 2009 give us pause. The Mariner's power deficit has been rectified while also improving fuel economy, and the alluring Sync system gives it a technological edge over its compact SUV rivals. However, its braking performance is poor, and there's no getting around the fact that its chassis is nine years old. While the 2009 Mercury Mariner is definitely worth a longer look than it was last year, don't forget about newer competitors such as the Honda CR-V, Mitsubishi Outlander, Nissan Rogue and Toyota RAV4.

Body Styles, Trim Levels, and Options

The 2009 Mercury Mariner compact SUV is available in four trim levels: I4, V6, Premier I4 and Premier V6. The base I4 Mariner comes standard with 16-inch alloy wheels, foglights, privacy glass, full power accessories, air-conditioning, steering-wheel-mounted audio controls, a four-speaker CD stereo, an auxiliary input jack and keyless entry. The V6 includes all of the base I4's standard equipment plus the 3.0-liter V6 engine. The Premier I4 model adds rear parking sensors, ambient interior lighting, leather/Alcantara upholstery, a power driver seat, dual-zone automatic climate control, Sync, an in-dash CD changer, satellite radio and an auto-dimming rearview mirror. The Premier V6 model pairs the Premier I4's standard content with the six-cylinder motor.

Options on non-Premier models include a roof rack, a moonroof, Sync, leather upholstery, a power driver seat, ambient interior lighting, an in-dash six-CD changer and satellite radio. Among the options on Premier models are 17-inch wheels, step bars, a moonroof, an upgraded seven-speaker stereo system, a navigation system and heated front seats. Class II towing preparation is also available on V6 models only.

Powertrains and Performance

The 2009 Mercury Mariner can be had with either front- or all-wheel drive. A 2.5-liter inline-4 that generates 171 hp and 171 pound-feet of torque motivates the I4 and Premier I4 models. The V6 and Premier V6 models come with a 3.0-liter V6 that churns out 240 hp and 223 lb-ft of torque. Both engines are mated to a six-speed automatic transmission.

Properly equipped, the V6 Mariner can tow up to 3,500 pounds. EPA estimates for front-wheel-drive I4 models stand at 20 miles per gallon city/28 mpg highway (19/25 for AWD models), while front-wheel-drive V6 models should achieve 18 mpg city/26 highway (17/24 for AWD models).


Antilock brakes (albeit with rear drums), traction control, stability control, front-seat side airbags and full-length head curtain airbags with a rollover sensor are all standard on the 2009 Mercury Mariner.

In government frontal-impact crash tests, the Mariner earned a perfect five stars in front and side crash tests. In Insurance Institute for Highway Safety testing, the Mariner scored the highest rating of "Good" in the frontal-offset and side tests.

Interior Design and Special Features

Fit and finish is good inside the 2009 Mercury Mariner, and functionality is boosted by a huge center console with removable bins. Satin-finish metallic accents and available leather upholstery create an upscale ambiance. However, while the front seats are nicely shaped and supportive, the rear seat is as flat as a day-old soda and offers neither a recline function nor fore/aft adjustability. To make matters worse, it's a pain to fold the rear seat down, as the headrests must be removed and the bottom cushions tipped forward before the seatbacks can be flipped down. Cargo volume stands at a useful 29 cubic feet with the rear seat in place and 66 cubic feet when that seat is folded down.

Driving Impressions

The 2009 Mercury Mariner's new-for-'08 electric power-steering system surprises us with its adequate road feel and responsiveness. As ever, this venerable compact SUV feels secure during spirited cornering, and this year's refinements to the suspension improve ride quality and make it more competitive in this segment. Brake pedal feel is good, but stopping distances are abysmally long.

Continuous transmission issues...company refuses to

by on
Vehicle: 2009 Mercury Mariner 4dr SUV AWD (3.0L 6cyl 6A)

My mom has a 2009 Chrysler Mariner and from the beginning it has had transmission issues. Shifting rough, jerking into gear and lagging between gears then rough shift. They have have had it in the Chrysler shop at least 8 times and it has never been fixed. Even with it obviously not shifting right they would tell us that they could find nothing wrong. When we are able to get a diagnosis, it will be fixed for a week and then it's back to mal-functioning. Now they are completely refusing to pay for any further repairs. This car is not worth the money simply because the company does not believe in fixing issues and it has been in the shop so much that it is difficult on day to day life.

Nice looking car; lacks comfortable

Vehicle: 2009 Mercury Mariner Premier 4dr SUV (3.0L 6cyl 6A)

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.

Love our new mariner!

Vehicle: 2009 Mercury Mariner Premier 4dr SUV (3.0L 6cyl 6A)

My wife and I just purchased an off lease 2009 Mariner Premier with V6 and everything except navigation. So far, we are thrilled with the car. It replaces a Honda Civic that was totaled. We have a baby coming in 4 months, and we were shopping Mariners anyway for more space. What you get for the price, in a manageable size, in such a nice looking vehicle really sealed the deal for us. Some of the "newer" designs were more expensive and did not offer as many features. We feel we got a very nice vehicle with lots of options in a nice package that we'll still have a very reasonable car payment and actually be able to put some cash away in the baby's college fund!

Vehicle: 2009 Mercury Mariner Premier 4dr SUV (2.5L 4cyl 6A)

I have had my Mariner for a year and a half and had my first accident in my life. I am waiting to find out if it was totaled, but hope it is not. I was able to walk away from an accident that totaled the other vehicle. All of the airbags went off, and I feel very lucky. I love my car and have truly enjoyed driving it! Gas mileage is good, the dealer was/is great and I wouldn't think of buying anything else! If there is one thing that is truly important, it is the safety of myself and family.

Transmission problems

Vehicle: 2009 Mercury Mariner 4dr SUV (2.5L 4cyl 6A)

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.

Great little suv

Vehicle: 2009 Mercury Mariner 4dr SUV (2.5L 4cyl 6A)

I just bought a used 09 Mariner I4. I had a V8 07 Ford Explorer. I actually like the Mariner better. The Explorer was smooth and quiet, but still felt a little sluggish, even with the v8. The Mariner handles better and is more fun to drive. The 4 cyl is buzzy on acceleration and at times at stoplights. Cruising at highway speeds it is quiet and smooth and plenty powerful, even with four of us and luggage.
