Steering Wheel locked up while driving
Bascially as she was turning into our driveway the steering wheel "Locked up" like the car was off. At the same time all the lights on the dashboard started flashing in sync.
She wound up going up into the grass before stopping.
Just another in an incredibly long list of problems, but by far potentially the most dangerous. Definitly the last straw with the car.

I've never heard of the steering wheel lock cutting in, but who knows if it could happen.

It was not the power steering. It was not hard to turn. It did not turn, totally locked, like when you try and turn a steering wheel when a car is off with no key in the ignition.
I havent experienced anything like this.[/QUOTE]
I would not have believed it myself if not for the fact the same car when I was driving put itself in neutral when i was driving 40mph one day. The car was actually still in "D" but the transmission was totally out of gear. I had to coast to the shoulder, put the car in "P" and back to "D" to get going again.

Flashing lights confirms that the issue was with belt. Any idler puller with locking bearing? Alternator spreading metal shavings around?

but the 2007 instance sounds like a keyless go problem. Maybe batteries in remotes are weak.
If anyone can either post here or email me with their experiences on how they resolved this issue, I would truly appreciate it.

Also with regards to insurance, there's usually a way to dispute the charge. Normally you have some kind of hearing. File the report and bring it as evidence and tell them it was a mechanical failure and here's the report you filed. You might get the point waived.
Went out to survey the damage. Since my butt was sticking out onto the street, I started the engine, put it in reverse and was able to steer the car, without issue, to park it behind the parked car.
Prior to the accident, I didn’t notice anything out of the ordinary. After the accident, when I restarted the car, everything seemed fine in the dash. After taking a few minutes to collect myself, I was able to drive the car about a mile without incident, before I pulled over due to leaking coolant/ smoke.
The serpentine belt is intact. The engine did not die while I was driving.
I have a mechanic coming to take a look at it today. I will update here and file with the NHTSA when he tells me what he sees.

My mechanic looked at the car. He thinks it was the mechanical steering lock that engaged while I was driving. He said there could be a few reasons for it to trip while I was driving. Could be a weak motor (it needs to push a spring or something?), and some other things I don’t remember. The most important thing is he said we can disable it so that it won’t happen again. I guess the newer steering columns don’t have the steering lock/ pin installed anymore since most keys have chips in them for security reasons.
He also said I should I definitely report it to the NHTSA because I was injured in the crash (minor) it’s classified as “1A” or something like that.
Mercedes have double engineered safety into the locks, so over and above needing a unique signal to engage the lock, once the key turns to position 1 the power is also removed from the lock all together so there is no way it can self engage,
