High voltage battery not covered by extended warranty...

Recommended Posts

Replacing a bad HVB will be no different than replacing a transmission in a non hybrid. With the advent of AWD, 6, 7, and 8 speeds, the transmissions are no longer a $400 rebuild. Some can be as much as $5000 to replace. My 1999 F350 transmission was $4500 just for the transmission not including labor to swap it out. Since the FFH uses an ECVT. the likely hood of it going bad is rare, these things last forever. Its just another item that may or may never need to be replaced. Too many people think of the battery are VooDoo, when all it is is just another major component in a complex car, no different than the engine or transmission. There have been fewer battery replacements in hybrids than transmissions or engine being replaced in non hybrids!

The Electric CVT is a totally different type of transmission compared the non Hybrid CVT. Those trannies dont hold up to abuse, so yeah, you will see a lot of failures, however, if you go to a certain "other" PPP forum and search for transmission failures, you may not find any. Since Ford and Toyota share the same design, chances of our eCVT failing are very rare indeed, if there are failures, its most likely due to assembly or bad part, then anything else, the chances of the battery going bad are much higher. Fewer moving parts in the Ecvt, plus the torque application in it is from the motors locked inside the housing, where the standard CVT the torque is applied at the flywheel, so more stress occurs on all the weak spots. CVT's also cannot handle a lot of horsepower, mainly due to the design, but the eCVT in the Hybrids are designed for the exact amount of power that is being applied and will never have it exceeded(unless someone boosts the ICE).
