After replacing my battery, car required voltage to be between 12.8-14 volts and i supported the initial start with a jump. Then let it run 15-20 min idle. Also, the aux ( secondary battery) had to be replaced for the crank. Make sure aux pos and neg terminals arent in contact with any metal sides of compartment if under seat. Then monitor for draining componants like not latched doors, dirty sticky power buttons, and fuses
Car died while crossing an intersection! Luckily my mechanic friend was with me. He said fill brake fluid then did a hard reset at battery terminal and started right up! With him and that knowledge i wouldve given up or paid way too much for tow and shop diagnostics for a 5 min fix!
Mine was in limp mode no crank no start. Replaced the main battery and aux battery. Needed at least a 12.8-14 voltage to not only start but more importantly to go into gear! Also first crank i supported with a jump, then let run idle for 15-20 min. Module resets for transmission and ESPwere essential.
