NHTSA Complaint #11438785 — 2019 JEEP CHEROKEE

Vehicle will not unlock or respond to key fab, after waiting it sometimes does, other times disconnecting negative battery cable and reconnecting it, function is restored. Far worse is at time when driving total electrical system failure occurs, engine fails, all dash board lights fail, light turn lane indicators and door locks. This has happened repeatedly and last time in heavy freeway traffic exiting. Took car to dealer and he said it was a low battery, this is the 3rd battery in 20 months. Dealer had car for 7 days and returned it now with Electronic Start Stop not functioning, after 3 weeks problems are still there, an independent mechanic says these are known Jeep problems, and confirmed it is not low battery voltage, I'm an electrical engineer and these failures happen when battery is at 14.0 volts, fully charged after 90 minutes of driving, and then car will start perfectly to only fail again. At this time I feel it's not safe to drive .
