Electrical system

63 reports3 crashes3 fires
“The vehicle had been stalling out on numerous occasions one being a freezing Xmas eve in Drive thru if it had happened somewhere isolated the driver could have frozen. I rented cars several times and replaced the alternator ,battery and at the final point at the dealership the mechanic suggested I purchase a $600 battery though I had a brand new one. The dealership gave me a $200 credit but it happened again, the mechanic in town said the Bluetooth component was draining the battery. They removed it and no problem since. The dealership mechanic talked around the issue and would not answer my questions about this. The safety issues related to this are dangerous and it appears to be known by mechanics about this model.”
