2008 Mercury Mariner throttle control powertrain light comes on, transmission cannot go into gear properly, it stops at 4000 RPM, and it struggles to go at higher speeds,

- South Weymouth, MA, USA

I realized sometime last year that my throttle was sticking when I would start the car and begin to take off. It was here and there and then I must have gotten use to it but now it does it even when I'm driving, it sticks all the time. Now it doesn't want to shift at the right times and it acts weird a lot, going up hills, when shifting from gears and so on.

The throttle is held open when the cruise control is employed but remains open when the cruise control is turned off both by using the off button and brake application. This happens at 75-80 mph on interstate highways in AZ and ut. The power brake booster is ineffective with no intake vacuum. This is very dangerous.

My wife and I were driving home on the interstate. We had just merged to the passing lane to allow traffic merging from an on ramp to enter the interstate a vehicle next to us was doing the exact speed as we were which was 72 mph set cruise control. I had vehicles approaching from the rear and since I was in the passing lane decided to speed up and get in front of the car beside us I pushed the accelerator on our 08 Mercury Mariner with a 3.0L engine to the floor and the car accelerated in front of the other car, when I lifted my foot off the accelerator the car continued to accelerate. I pushed on the brake once with nothing changing the car continued to accelerate. I proceeded to pump the brake three additional times in about 1 second intervals. Finally the accelerator pedal release and the car slowed down. We preceded home without further incident. This is a very dangerous condition and has resulted in serious injuries and deaths in earlier model years of Ford escape, Mercury Mariner and Mazda tribute vehicles. I have had Ford vehicles my whole life and have been working on vehicles for more than thirty five years. This is not normal and is not the only time or vehicle this has happened to in this year there are many other similar people that have similar complaints on these Ford and Mercury SUV's on the internet ex: Carcomplaints.com to name just one. The internet is filled with these dangerous complaints. When are you going to live up to your name and put the safety aspect first, when dealing with these to rich to be bothered by recalls auto manufacturers?

Speed shift forced on 2nd and 4th, the vehicle has only 77000 miles and transmission is bad, contacted the dealer about the problem and no action taken, they said the vehicle is not on a recall campaign and owner needed to do repair and if the campaign started on this problem in the future they will reimburse the repair amount, I need the vehicle on a daily basis and now I'm stock with the repairs cost of 1500 plus labor. I need to add this vehicle to the recall as shown here: Report receipt date: Sep 29, 2015 NHTSA campaign number: 15V606000 component(s): Power train the vehicle was in motion when it happened, speed was reduced and wrench light came on the dashboard

Same results of the consumer satisfaction program 13N03. A defective throttle body. Car began to stall/choke out while accelerating. It continued to do so until it finally left me on the side of the road. Ford is aware of the problem but because my car was built at a different time/plant does not offer assistance for a known unsafe problem. This started on the freeway and continued after I exited for fear of stalling on the freeway. Car has to be towed/repaired at my expense. A friend has the same model vehicle/same problem last year, but due to her car being built at that plant/time was compensated for the same exact problem. Again, Ford is aware of the problem but minimizes coverage. I can't help but think of what could have happened if my wife/daughter had been driving(at night). In reality, it is unsafe and I could have been killed.

In cold weather my gas pedal sticks. Even after I have started my car and let run for 10-15 minutes. When I get in, reverse to forward position and try to accelerate- the gas pedal sticks. I have to slam on it for about 2 minutes before it actually works. This has happened while driving as well, not just the initial start. It definitely happens more in cold weather. What can I do? after research this sounds like it's a common problem with 2008 Mercury Mariners. I believe it's definitely a safety issue.

Acts like throttle body failure. No power when accelerating but rpms go up and then surges when finally throttle works. Wrench light on.

I had just made a right turn and was proceeding down the block when I heard a sudden "click" and lost power. I couldn't steer and there was no power. I managed to get the car over to the curb and turn off the engine. I restarted it a few minutes later and it started up ok. However, the rsc warning light stayed on even though I had never pressed that button. This is not the first time this has happened. The first time it happened I was told it was a battery problem so I got a new battery. That was less than a year ago and I can't imagine I need a new battery that often - that simply needing a new battery will cause my car to fail! in doing some research I've come across several instances of the same issue necessitating replacement of the throttle body module with trouble codes P2111 and P2112 and, in fact, the North Carolina consumers council (nccc) has officially petitioned the national highway safety administration (NHTSA) for a defect investigation of alleged throttle body failures in 2005-2012 Ford escape vehicles sharing the same or substantially similar part. Luckily I was only on surface streets and not the freeway. It's only a matter of time before this happens on the freeway! is there going to be a recall?

Without warning the gas pedal sticks, will not function. This happens intermittently and seems to disappear when the car warms up, but also has happened when the car is warm. Very dangerous when trying to accelerate or just drive normally. This seems to be a widespread problem with both the Ford escape and the Mercury Mariner. We have been stranded several times. This needs to be fixed by the manufacturer.

While driving my car stalls without warning then it jerks real hard and takes off so I have to ride the brakes after coming to a stop before I can press the gas peddle it takes off so I ride the brakes. While driving again it picks up speed on its own very scare please help.

Vehicle does not accelerate from rest. Press gas pedal - vehicle does not go - then all of sudden it takes off. Dangerous scenario at stop lights. Dealer says issue is defective throttle body.

- Coralville, IA, USA

I pulled into a gas station to turn around. When I came to a complete stop and pressed the gas pedal to go, my gas pedal wouldn't budge it was like it was stuck. When I pulled on the highway it done it again but it took longer to get my gas pedal to press down. When I come to stop now I have to keep my foot on the break and the gas pedal to insure that it will go when I press the gas pedal.

The throttle/gas pedal in my 2008 Mercury Mariner kept sticking and eventually breaking. I had the car towed and taken to a repair shop where they inspected the cable unhooked from the pedal when the technician hooked the cable throttle to the pedal it would not move when pressing down on the pedal, the throttle plate stuck. The technician removed and replace the throttle body assembly. I researched online and found that my issue is the same issue that was a Ford escape recall back in July 2012. Is this something I can contact Ford about to see if this should also be part of their throttle cable recall.

- Bothell, WA, USA

I was driving along the highway and the gas pedal just went to the floor. The engine was still running but I could increase the power. I had to coast across three lanes of high speed traffic in order to get my vehicle safety to the side of the road. This the second time the accelerator cable in this vehicle has snapped without warning. My dealer replaced the first cable last year and just over one year later the same cable has snapped. I was fortunate not to panic and was able to bring my vehicle to the side of the road. This cable snapped twice while I was traveling on the highway. I had no control over my vehicle and could have killed or involved in an accident. My dealer is replacing the cable under my extended warranty but are charging me to replace their defective throttle box. Ford/Mercury needs to recall all Mariners and Ford escapes asap.
