What owners say
While driving south along I-95 at about 65 MPH, I felt a sudden shuddering, I slowed down to determine if it was rough pavement and the rear right side tire blew out. These tires are newly mounted, within the past five months by my ford dealer. I pulled off the road and had aaa remove the tire. Upon inspection, there were no punctures to the tread only a blown out sidewall.
Vehicle was going about 35 MPH when all of a sudden it started shaking. Then, lost its traction control, and caused the lights in the dashboard to turn off. This eventually LED the engine to shut off, and the driver lost steering. Taken to dealer for a checkup, but the results showed that the cause was undetermined.*ak car shuddered, followed by engine shut down resulting in loss of power brakes and steering. *bf
Several months ago, I reported a shudder or vibration in the transmission at speeds over 25 MPH. I had been told that either the torque converter or 85% of the time the transmission fluid was the problem. A new mercon 5 fluid was being used to eliminate the shudder or vibration. I took the vehicle in today to ford, who is now reporting the clutch to be going out. I find this very unusual at 48,000 miles with the previous diagnosis given. It sounds like there was a manufacturing defect with the transmissions or related parts for this vehicle. Also both electronic windows on the driver-side have gone out...regulator parts broken. Help!
Tranmission/torque converter has a shudder when shifting at about 50 MPH, I have done some research regarding this and have found 19 tsb's regarding the transmission/torque converter from jan. 1995 to july of 2003. This is on my 1995 mercury grand marquis. I have contacted ford/mercury and have been told the cost of diagnosis and repair is my responsibility. It would seem to me with so many tsb's on this problem there is a mfg. Defect involved, and should be fixed by the mfg.
We have owned a 1997 grand marquis for approx 3 years. We have noticed a shudder and/or vibration in the transmission at various speeds, ranging from approx 27mph to 55 or 60 MPH. It appears to diminish upon acceleration at each point, but returns later. The vehicle has less than 45k miles. It didn't have this problem when purchased. Is this a recall safety issue or manufacturer's defect? Will this lead to further, more problematic difficulties or does it smooth out after increased driving? Can an additive completely eliminate the shudder without damaging anything else? Thank you.
While driving over 45 MPH consumer felt transmission shuddering and vibrating. There was a technical service bulletin concerning this problem. Consumer had not informed the manufacturer or the dealer about this problem.
The transmission was replaced. The virbration/shudder continues. The going into reverse problem appears to be solved.
Transmission vibrates, slips (sounds like driving over rumble strips) during moderate acceleration. The vehicle shudders and vibrates when traveling in 3rd and 4th gear and then loses power.
Power train shudders at speeds 35-40 MPH. Wiper will not return to down position. Brake switch at brake pedal wire breaks and vehicle will not gear selector is locked in the park position and no brake lights. Air idle solenoid hums loudly. Engine loses oil and no apparent oil leaks. Brakes makes grinding noises after replacing rotors and dealer brake pads front and rear. Power window on drivers side works intermittently.
