Tl* the contact owns a 2005 mercury montego. The contact stated that while driving approximately 60 MPH, the vehicle jerked without warning. The vehicle was taken to a dealer where it was diagnosed that the automatic transmission valve body needed to be repaired. The manufacturer was not made aware of the failure. The vehicle was repaired. The approximate failure mileage was 51,000 and the current mileage was 51,487.
On 2/27/13 throttle was cleaned not replaced per ford recall 12no3. On 5/18/13 being stuck in construction traffic at a stand still, foot on brake engine proceeded like a 747 getting ready to take off. Car moved forward some 1 to 2 ft.. Killed engine, turned it on again with foot on brake car proceeded to move. Killed engine, turned back on. No other problem until I was at a stop light on way to destination. Again engine begin to whine at high rate as if I was in neutral and had foot a gas. Killed engine and was able to proceed to destination without problem. Took vehicle to ford dealership on 5/9/13. Dealership did diagnostic, found throttle body bad. Had to be replaced. There was on or about 3500 miles on vehicle since time of cleaning to repair. Of the 3500 miles, 2000 was on our trip. Talked with ford corporate stated dealership problem not theirs. Ford is aware of this problem and has chosen to clean rather then replace. It is my understanding that this throttle control ties into the transmission in which ford has had their share of problems.
After driving car 20 minutes and once the car engine heats up the transmission begins to buck and jerk while driving under 40 MPH. This is a ongoing issue and is very dangerous.
Tl* the contact owns a 2005 mercury montego. The contact stated that while driving 35 MPH, the check engine and transmission light illuminated and immediatetly after the vehicle stalled. The vehicle was taken to a dealer for a diagnostic test who diagnosed that the mechatronics unit needed to be replaced. The dealer replaced the mechatronics unit but the stalling continued. The vehicle was taken back to the dealer who stated that the transmission needed to be replaced. The failure mileage was 40,525.
The car was purchased in may of 2011. August 2011, the transmission started to violently jerk and act as if it were in neutral. When gradually applying the breaks, the car would begin to shudder. This would happen only if the engine was warm. By march 2012, the shuddering transmission and jerk was constant. I took it in to be looked at in april of 2012. The alternator was replaced, due to what we thought was a bad battery. The mechanic believed this caused the transmission to jerk. The problem was not solved. June 2012 the transmission was replaced by a ford dealership for 5,000. July 2012 the car went into fail engine safe mode, the codes pointing to the throttle body. A mechanic cleaned the throttle body saying it might solve the problem. 2 days later the car went into fail engine safe mode again with the same codes with an estimate of $900. The car has 72000k on it and has had three major problems in the past couple of months.
The car will shutter, shakes and bangs when the transmission down shifts to a lower gear when for example the car begins to climb a slight grade and needs a lower gear to maintain speed. Sometimes, during the same scenario, the car will shift momentarily into what seams to be neutral causing engine RPM to spike from 2,000 RPM up to 6,000 RPM. In either case, it scares you and you think something major is wrong with the car and you immediately search to get off the road and stop. The cars around you abruptly try to avoid your sudden decrease of speed. On the other hand, the car seams to accelerate normally while up shifting to speed although maybe the shifts are getting a bit harder than we were used to. The dealer replaced an engine mount anti-torque bracket for $600.00 that they determined was the problem but it did not help. No diagnostic lights appear on the instrument cluster giving reason for the problem. We basically do not trust the car to travel any where because it is unsafe. I see many others on the web have the same issues with their montego's. We have maintained our car very well during its short life. The dealer and transmission shops are perplexed to the solution of the problem. The dealer says now that maybe it is a "valve body" causing the problem but are not quite sure. $2,400.00 dollars for a "not quite sure" fix is a bit much specially after already sinking $600.00 into the problem. Ford, what do you think? Time to issue a recall and admit there is a real safety problem here? Be fair and help consumers remedy the transmission problems they are having with their 2005 montego's before someone gets killed!

This car at 35 MPH loses power and will not shift into a higher gear.I have found atsb08-24-1-.this dates back to november13,2008.the ford dealer has told me repeatdly that there is no problem and my car is fine.I asked if they knew of any problems and they stated no.when the car does this it just loses power and you have to slow down and accelerate very slow and hope the transmission engages.
The throttle body is bad on this vehicle. This is a well known issue that ford needs to recall.
Tl* the contact owns a 2005 mercury montego. While driving approximately 35 MPH, the transmission began to slip violently in a jerking motion. In addition, a loud noise emitted outside of the vehicle. The failure occurred nineteen different times. The vehicle was diagnosed by a certified mechanic who stated the transmission would need to be replaced. The vehicle had not been repaired. The manufacturer was notified and they informed the service warranty expired. The approximate failure mileage was 32,000.
Purchased car on 10/3/2011 from drivetime motors. On the way home, car had obvious transmission problems. Took in for service on 10/5/2011, and transmission was replaced. Upon testing, prior to pick up, the mechanic found that transmission to be a bad one. Replaced with another lkq transmission. Picked up car on 10/27/11. On 10/29/2011, the check transmission light alerted in car. Parked car at home. On 10/30/11, drove car 2 miles to church and backed car into parking space along tree line. An hour later, sent child to retrieve an item from the trunk. Child walked around to the trunk and used key fob to open the trunk. As he leaned to remove items from the trunk, car rolled backwards and knocked him down, luckily, car was stopped by tree limbs on ravine of tree line, as child rolled down ravine. Resulting injuries were head contusion, concussion and badly bruised arm and back. Drivetime said they could not find anything wrong with the car, and wanted me to pick up and assume ownership. The car was not running, had no key in the ignition, and no one inside the car. A police report was filed and pictures taken of the gear shift showing the car to be in park. I am not going to reclaim the car, and am afraid that drivetime is going to return this car back to a dealership to sale and endanger someone else's life.
The check engine light came on. I took the car in for service. I was told that the throttle body needed to be replaced. That cost me $736.83. This was done on 10/06/2010. Now again the check engine light has come on so I took the vehicle in for service. I am now told that the throttle body has gone bad. This time the estimate is $950.00. My mileage is 90,361. Now a little more that a year after the first repair I need to perform this repair again. I believe a recall needs to be forced on the ford motor company for defective parts that are being installed on their vehicles.

Driving on the highway on february 10, 2011, started to pass a truck and noticed that I was losing power - I looked at the tachometer and noticed the RPM's increasing. I took my foot off the gas and got back into the right lane. As I got further down the interstate, I heard a loud, screaming noise, and I continued to lose power. I pulled onto the shoulder of the road as soon as it was safe (I was on an overpass). The car continued to run but it wouldn't go into gear. I had the car towed to a transmission shop where they checked and replaced the cv axel assembly and replaced the transmission fluid. In march 2011 I noticed the engine seemed to be misfiring so I took it to an auto repair shop where they said the plugs needed replaced and one motor mount was broken and needed replaced. I was leaving for vacation so they said it would be ok to drive to the airport and return and then bring back for repair. I took the car back on tuesday april 5, 2011. While checking the car out, they found the part replaced for the cv axel was once again broken, which they replaced. I picked up the car on friday april 8, 2011. I left the auto repair shop, drove approx 20 miles when I noticed the same problem starting. I returned to the auto repair shop and they said the cv axel problem was again occurring - the splines were broken. Car was taken to the transmission shop where it was found this time to have an internal transmission problem, said the cv axel assembly would be warranty, but it would be approx $4,000 to replace the transmission with a rebuilt one.

I own a 2005 mercury montego that has been a constant downward spiral.approx. 3 months ago, I had to replace the vehicles transmission,because I was told by ford that they do not sell the tools or parts to replace anything in it, the whole transmission had to be replaced.approx. 1 week ago, I was sitting at a traffic light and my car revved up to approx. 3500 RPM and pushed my car forward into traffic. I then traveled about a mile down the road and the car started bucking and engine fail safe mode was activated on the dash, along with a small wrench symbol on the message board.I then checked the owners manual where it said it was for the throttle control, and transmission. I immediately called the shop where the transmission was put in, and was told to bring the car there immediately. While on my way to the shop the same day, numerous times I would push the accelerator and the car would do nothing, it would not go at all and then would accelerate after approx. 5 seconds. I eventually made it to the shop where the car was placed on a computer that said there were no codes coming up for the warning that came on. After already spending $4,000 on a transmission, again I spent another $200 to change all of the spark plugs and clean out the throttle control box, which has done absolutely nothing for the problems with the vehicle. In january 2010, I called my dealer to set an appointment to have my transmission fluid changed as a maintenance call, and was told that ford does not recommend that you change your fluid until 150,000 miles, is that normal? Why are all of these transmission going bad, and why are these vehicles accelerating by themselves? Nobody seems to have answers for any of these questions. Why are these not being recalled like toyotas were? Are you guys waiting for people to die because of this, will that get your attention? This is obviously a computer issue within the car,same system that is in toyota's. Do something about it, before someone's hurt!
I recently had to replace my transmission replaced in my 2005 mercury montego due to inter problems within - I went on line and there are hundreds of complaints about the same problem with the transmissions in ford and mercury cars. I took my car in and was told there is no recall - I took my car to have it fixed and my mechanic tried to get parts, and a manual to have it fixed but ford would not sell him anything to fix the transmission. Before I go further we first took it to the ford dealership to see how muchit would cost they said it would start about 4,000 dollars we could not afford that and took it to a transmission place and it was finally fixed after being in the shop 14 day due to the fact that he could not get parts or anything from the ford parts department. He finally had to get a total different transmission for the car. I contacted ford in dearborn, michigan a few times and only got the response - sorry there is nothing we can do because there is no recalls - I feel like screaming that with a transmission that would make you feel like you are riding a bucking bronco and then it would shift to another grear and then just idle in the middle of the street and you would think great it's going to just stop and someone is going to run into the back of me and worst the side of the car - if that isn't a safety issue I don't know what is - please check into this go online and check the complaints -also, the car only has 61,000 miles on it and that is the complaints from others online. Yet ford will do nothing to address the issue or even say there is a major problem.
On june 22, 2010 I noticed the engine warning light come on. About 1/2 mile further the transmission starts bucking and jumping. The 2005 mercury montego was having a difficult time pulling a 15% grade, once to the top everything smoothed out. Then 2 miles further another hill came. The 2005 mercury montego started to buck and jump once again. I made it home that evening. The next day I called the dealership and explained the situation. It was decided to take the vehicle in to be looked at. What was found was an instrument cluster defect that was changed out after a four day waiting period to receive the part. Then the service advisor called and stated that the transmission control module (TCM) was defective. This part is not covered by my warranty! It will cost me $1,700.00 to replace this part. Now I an finding that there are a lot of complaints like this for this particular year and model. So my question is..how many people have to die before the federal safety agency will pressure the ford motor company into making their cars safe to operate on the american roadways? Who is willing at the federal safety agency to put their family in an 2005 mercury montego knowing that the transmission control module could malfunction at any time causing their family to be stranded on a freeway or in a busy intersection? Come on and step forward you can borrow my car!
2005 mercury montego premier has been experiencing rough and bucking transmission shifts at 2nd and 3rd gears, very occasional shift into neutral by itself while in motion and accelerating and shuddering transmission shifts during deceleration or braking since approx. 50, 000 miles (25, 000 miles before my extended warranty expired). Dealer service was consulted multiple times. However, I was always told there were no computer codes and that technicians couldn't "duplicate the condition." therefore, I have lived with the condition since then. That is until this morning when I was almost rear ended and run over by a semi because the transmission shifted into neutral while accelerating on the on-ramp to I 95. This condition is dangerous. I see that there are many others with the same problem on this site and on fordforums.com. It is a matter of time before this defective transmission fails to operate and causes a serious accident in one of these vehicles. Please, listen and take action.
My 2005 mercury nontego has 62550 mi on car heard noise in transmission and took to dealership and it needs a new transmission after looking on line numerous poeple have had problems between 54,000 mi and 67000, mi , the transmission needed to be replaced I called ford corporation and they stated because there is no extended warranty on the vechile they can not do anything for me . Speaking with numerous mechanics there is no way a transmission sould go with that kind of milage. Ford corporation said they it is against company policy to give any type of credit for this problem. With so many people having the same problem I would think that ford would step up to the plate. I really think that ford should initiatte a call back on these transmissions, but they said they will not initiate anything unless national higway traffic safetiy and administration itnitalizes the call back. So I am writing in response to their respnse. You would think a corporation like ford would initiate their own call backs with the noted problems, just to save reputations
2005 mercury montego has close to 90k miles. Kept in great condition but the transmission is giving same signs as reported many times on this thread. Jerking between gears and kicking back really hard. The company will hear us if we join together we're learning that with toyota. Let's get together and fight this one.. It's not fair!!!! Facebook me [xxx] and let's get a plan. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
I purchased a new 2005 mercury montego in may 2005. The car now has 85k miles with the 6 speed transmission.the transmission has been fine on short trips (35 miles or less) but anything over that and it starts doing really crazy stuff. It will downshift 3-4 gears at highway speeds...slam into gear... Then immediately upshift. This happens so hard that the whole car shakes. One time it was so bad, we felt we had been hit. Sometimes it will go to downshift, and just goes to neutral causing major issues when involved with traffic trying to get of the road. This is a major problem which could cause an accident. When shifting from 3-2 at low speeds, it will downshift but shudder the whole car. All these symptoms occur only after trips longer than 35 miles or on a very hot day where the transmission seems to heat up. My local ford garage has tried reprogramming the TCM with no success (first tsb). They now say I need a remanufactured transmission at a cost of nearly $5000. Ford will not help in any way even though I firmly believe this is a factory defect. The car has never been abused, been in an accident, and maintenance performed at or sooner than recommended. The shifting into neutral is a safety issue. Ford needs to step up and admit they have a problem and replace the trans, it appears as they have fixed the problem because all the tsb's for this symptom (2 that I know of) affects only vehicles manufactured before oct 2005. How can ford or any other company know they have an issue and not take corrective action. I have always been a ford man since the early 1970's. How I have been treated with this defect could be construed as criminal. I guess they figure if they hold out long enough, the vehicles will all die and go away and they wont have any obligations whatsoever. In doing research on this vehicle with the 6 speed trans, there are lots of us in the same situation with the same symptoms and the same reply from ford.
