Ford Mondeo Steering Issues
I own a 2007 Mondeo, which I have had for a bit less than 3 months now.
Around 2 weeks ago, I changed my tires & rims from 255/55/R16 to 225/40/R18 and there was no issues with the steering (it wasn't stiff or anything after).
Around a week ago, when turning at around 30-40kmph on a bend, I gave it some more gas and the steering wheel went numb (locked itself prob.) for around a second or so (didn't move at all and didn't also start returning it to the 0-position right away) and I thought something weird had happened.
After finishing the highway, I drove around in the city, noticing that the steering became waaay heavier than it was before, still drive able, but very annoying on twisted roads, big bends and roundabouts.
Yesterday, I took my car to be checked by the local Ford dealer and they assured me everything was fine with the hydraulics, I personally have also checked the liquids & tire pressures and they were all fine.
What can possibly be the problem here? Can it just be that my dealer doesn't want to be involved in any way with the problem or can it really just be that something happened with the tires for example?
Would really appreciate any response.
