Another thing to note is potential liability (for Toyota) of a Prius owner driving in EV mode and then hitting a pedestrian... I'm sure the legal team over there has warned management about the nightmare scenario this would cause (due to legal deeppockets approach) ... unless there was a strong disclaimer. So my take is that they won't neccessary void your warantee, but this is one of those things that makes it clear that if you get into an accident with your silent Prius and a pedestrian, Toyota is clearly not at fault. Probably the only reason they left the EV switch off the car here... we're way too litigious a society for risky innovation.DanMan32 said:Legally, Toyota probably can't void the warranty, unless they can prove that you damaged the HV ECU or the harness with it, but they have said in their FAQ that making it plugable AND adding a switch to make it run in electric would void the warranty. It's the AND in that statement that seems to be a loophole. However, US and Canada are the only markets that don't have this switch from the factory, yet the HV ECU has the programming for it. All Coastal's mod does is provide a fancy way to send the EV signal, the same way an ordinary switch would; another reason Toyota would have a tough sell in court to deny warranty.
That was my thinking. My car goes silent in parking lots all the time all on its own. I hardly use EV. The only time it makes noise is if the AC is on (which is most of the time) so that the cooling fan motor and compressor are running, which almost sounds like ICE.KTPhil said:Actually, I see LESS liability from Toyota in driver-selected EV mode. The car can enter this mode all on it's own right now. An accident in EV mode that the car did NOT select would point toward the driver as liable, not Toyota.
