Just put a new IMA battery in and it has a new regular battery. Test drove the car for several miles after installation of IMA battery and everything was good. The next day it repeatedly blew fuse 53 and 42 may be blown. Mechanic says possibly relays (not sure of correct terminology) from the IMA battery need to be replaced but we can't seem to find them to buy. He does not specialize in hybrids. Any suggestions on exactly what I need? What to order? Where to order?
