When hi-tech goes bad, it can get ugly.

Summary:
A defective Mercedes "4Matic" system caused the rear tire to explode causing $25,000 in car damage and $1500 damage to home. Mercedes and the dealer will not stand by the car and only tell us that it is an insurance issue. Automotive warranty items, including factory defects are not covered by insurance - only the resulting damage is.

 

Amazing that the dealer seems to think it is not their fault. I mean, when sony batteries explode on laptops it is their fault as it was part of their product. This is regardless of the insurance on a product.
Crazy!

 

'4matic' is half braking and half four wheel drive, not all wheel. brakes areapplied todifferent wheels as needed when slipping. how would applying the brake make a tire explode? this doesn't make sense.

 

That report does not make any sense at all. even if you left the car in drive without raising engine speed with the gas pedal, the wheel speed would not
reach 200mph. come on! the guy is blaming the traction control system as faulty. what he did not metion is that even if brake pressure was not applied to slow that wheel, as a default engine speed is reduce so much that engine speed would not be able to spin the wheel that fast. Oh yeah has fast do you think a car can go in reverse? he say that a speed of 50mph freewheeling is 200mph. 50mph in reverse? well anyway in my opinion is that his findings do not make any sense.
