I was driving down an interstate freeway at 65mph and came to a curve, the steering was very tight and was unable to keep the car in my lane. Luckily there was no one next to me at the time. From that time on the steering kept getting tighter and tighter. I had to use bodily force to physically turn the steering wheel. I took the car to an auto repair shop and the issue was diagnosed as a faulty steering shaft joints. I had to have the lower steering shaft replaced. I was informed that 2005- 2011 Mercury Grand Marquis were recalled for this issue. As of writing this 2004 Grand Marquis are not included. This is a major safety issue and should be looked into further. I believe Ford/Mercury should be responsible for the cost of this repair.
