Consumer states that while driving at any speed and with no warning throttle pedal would stick. Dealer notified.
I have had numerous problems with my '99 cougar such as, failure of my pat system and computer system. I have had problems with my brakes which they can't seem to figure out the problem. I have had my starter replaced twice. I have had defects in several sensors, which is not under warranty that I had to pay a good amount of money for them to repair. My fan has even blown out. There is a burning smell whenever I turn on my heater that none of the dealers can't seem to smell. I also had to purchase a new radiator. When my computer went out my car was still under warranty but they made me pay for the repairs, parts, and labor out of my pocket. This is not all. The list goes on and on. I have complained to the dealership, ford motor co. And even had someone from ford to investigate all of the problems I've had with my vehicle. They have been rude to me on several occasions, especially when I had questions about the repairs of my vehicle. Something needs to be done about this. I would not recommend the purchase of a mercury cougar to anyone.
While traveling on highway throttle will stick. When taking foot off of pedal, engine doesn't slow down. Dealershipwas aware of problem.
Engine light came on I thaugh it would be an electrical problem, it was not.the car would jump and accelerate when stoping at traffic lights and stopped traffic when I would press on the gas lightly. Dealership said it would be $2000. To fix. I did not extend my ford warranty. They said there was a hidden warranty with the engin and that I would have to pay $500. He aslo said I couldn't have been anything I did, the engine was coming apart, that would be the manufaturer's fault. I wish I would have not baught this cougar, its been nothing but problems and recalls. I have went to the dealership so many time I've lost count.
Vehicle cuts off on an intermittent basis while traveling any speed on highway. Vehicle accelerates and headlights, and warning light illuminate before vehicle shuts down. Dealer has been contacted. *ak
Vehicle experiences sudden acceleration causing temporary control problems, consumer states on some occasions the accelerator will pat her foot just before it suddenly accelerates.
Passenger's seat will not lock in place unless seat is positioned all way to the back closely to rear seat . *ak consumer states the seat if unlocked and moved foward will only relock when pushed all the way to the rear, then seat can be adjusted and locked from any position, the problem is that you can not lock the seat if anything is placed behind the seat, in trying to lock the seat consumer states she has the crush her grandchild's feet in the car seat, consumer states there is a strong to light gasoline odor, also gas pedal will stick in up position and need strong push to release, door locks automaticcalylock and unlock at any time, the locks were finally replaced and consumer was given an extended warranty, consumer states radio goes out and the display disappears when it is hot.
The vehicle developed a starting problem, it would crank excessively before starting, the dealer replaced the fuel pump but that only temporarily solved the problem as it returned shortly after replacing the pump. Nlm
While driving about a low speed vehicle will suddenly accelerate without a prior warning. Consumer had taken vehicle to dealer for repairs, but dealer's personnel could not duplicate problem.
Car leased in 1999. Since then there have been several complaints, the radio shorting out, 2 same side/tire blow outs, trouble lights and transmission problems, brake noise and acceleration problems. In each and every case the response has been "we cannot reproduce the problem" hence, no fixes. Warrenty expired now the alternater needs to be replaced? Comment from service department "it must have been defective". ???
Loud hum and RPM fluctuation at all speeds. Vehicle will accelerate on its own. Dealer says replacement parts are backordered and have been for 3 months.
While driving the throttle will stick causing the engine to rev up when I push in the clutch, it lasts anywhere from 5 to 10 seconds at a time. It is off and on, somedays it does it, then other days it's fine. I have takin it to the dealer twice before now, the first time they replaced the idle air control valve which seemed to fix the problem, then approx. 3 months later began to do it again, so they put a new throttle body in it, that lasted about 3 weeks and now im taking it back again.
Cruise control will not disengage with a tap on the brake - it must be fully depressed.
While driving at approximately 40mph vehicle stalled without any prior warning. Towed vehicle to dealership & was informed it was the iac solenoid which needed to be replaced.
Transmission surges and hesitates upon accelleration causing unexpected increases in speed; rear hatch will not open; brakes still grind after replacement; after door latches replaced, car now makes whining noice; starter replacement makes high pitched noise; coolant light comes on--dealer's solution is to overfill coolant level.
While driving on the highway vehicle will race to very high rpms, and then completely shutdown without warning. Please give any further details.
Throttle will not close when shifting gears below 3500 RPM's. Car will actually accelerate when letting off the throttle under 3500 RPM's. When down shifting car will accelerate also if shifting under 3500 RPM's. Very dangerous in traffic as driver must constantly ride the brake to slow auto. Car is a stick shift and mercury has stated that the problem is a minimal reported problem but they are aware of it.
Car's warning light stayed on constantly, took in first time was told electricle wiring, had taken in 4 more times then break lights failed they explained it was mechanicle malfunction, passenger seat cable broke been waiting since 8/26/99 for replacement, cruise control stopped working, warning for coolant keep eluminating
