What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
On friday, dec 13th, I was driving home in cruise control at 60 mph. My blood pressure dropped suddenly and I passed out at the wheel. I woke up just in time to crash, no time to react. I impacted, head on, a creek bank after jumping over the creek.
Power steering control module pscm) and cluster module went out, steering is not safe, very hard to steer
Check engine wrench came on vehicle began to loose power. Gaylord ford found no recall because the car was build august 2009 in the same plant as other vehicles with the problem with the throttle sensor for powertrain. The vehicle lost power and would only go 30 mph. Car is a 2010 milan hybrid 133,000 miles.
I have been on the phone with ford. An extremely mad and rude woman didn't or couldn't answer any questions I had. She kept telling me I got my recall be cause they checked my computer system but didn't replace the recalled steering module.
Brake warning light and a message on the dash saying "check brake system" intermitantly occur. Brakes seem to work normally. Restarting the car temporarily fixes the problem, only to occur again in several miles. The problem occurs at any time, standing or in motion.
Was stopped at a red light, car had been driving fine, but when the light turned green and I proceeded my car suddenly had reduced power and would not drive more than 40-45 mph. No lights or anything came on the dash the first time. The second time however a yellow/orange wrench light appeared.
While driving and attempting top accelerate up to speed, the vehicle began to slow and hesitate. It would not properly accelerate. After going a short distance at reduced speed, the vehicle began to shake and hesitate. I was able to make it home (luckily not too far).
The contact stated while driving approximately 55 mph the vehicle began to decelerate and proceeded into limp mode and the wrench light illuminated. The manufacturer was not made aware of the failure. The vehicle was not repaired. The vin was not available. The approximate failure mileage was 30,000.
