Vehicle malfunction due to cell phone interference is highly unlikely. Automotive tests are performed at a significantly higher level over a very large range of frequencies.
Automotive also supports on-board transmitter testing to ensure that 100 watt radio users won't cause malfunctions. The most that I have seen from a cell phone is a some beeps and pops in the audio system. Anyone care to guess how many micros are in an automobile?

Cell Phone Turns On Oven - Popcorn II? All the more reason not to use cell phones while driving your late model automobile now stuffed full of the all-important microprocessor and associated electronics. I can imagine all sorts of nasty interaction with anti-lock braking and cruise-control systems. And why does a range, microwave oven or a toaster need a microprocessor in the first place?

Cell Phone Turns On Oven - Popcorn II? I wonder if Andrei normally leaves his cell phone balanced between two of the cooktop burners? OTOH, I would expect to see 5 to 10 V/M at two meters distance from a cell phone, so at a half-meter or less, I would be surprised to NOT see some interaction. And then, on yet another hand, proximity of cell phones should be expected for household systems. If your system just happens to be a controller that regulates watering, flame cooking, microwave cooking, radiant heating, etc; you should verifying that immunity doesn't create a safety hazard. An appliance manufacturer shouldn't kid themselves that slapping a microprocessor into a gas oven doesn't create risk that isn't addressed by safety standards that were written for manual appliances.
