Infiniti hybrid vehicles shut off engine while moving to protect the hybrid system from over heating. this happened on 5 or more occasions all while driving down the street or highway causing me to lose control. when notifying the dealership they were aware of this issue and after 2 times bring it in and nearly $1000. the day after coming out of the shop and being fixed for the 2ns time, my car turned off driving down the freeway in rush hour traffic causing me to lose control and smashing into a vehicle at 50+ miles an hour. the other driver and self were injured and luckily not killed infiniti has yet to work with me or respond to this serious issue. i have found other infiniti hybrid owner this is happening to please contact if you also have had this issue. *dt*jb
