2014 Chevrolet Captiva

FREQUENTLY CAR WILL NOT START EVEN WITH GOOD BATTERY AND CABLE CONNECTIONS. WHILE DRIVING CAR WILL LOSE POWER. THE 3 GAUGES(RPM, SPEEDOMETER, AND GAS) ALL STOP AND WORKING. THE CAR WILL STILL RUN BUT AT A MUCH LESS POWER. SOMETIMES THEY START WORKING BUT RPMS WILL RUN VERY HIGH AND SPEED IS GREATLY DECREASED. MESSAGE COMES ACROSS TO SERVICE STABILITRAK AND TRACTION CONTROL. WARNING LIGHTS COME ON SUCH AS ABS, TCS WARNING,STABILITRAK INDICATOR, AND PARKING BRAKE WARNING. DOORS LOCK AND UNLOCK REPEATEDLY. AT TIMES HAVE BEEN ABLE TO RESET BY UNHOOKING BATTERY CABLE AND RECONNECTING AND WAITING. NO PATTERN AS TO WHEN AND WHY IT HAPPENS. MAJOR SAFETY CONCERN. HAVE EVEN REPLACED UNDER-HOOD FUSE BOX. OH AND KEY GETS STUCK IN IGNITION. WHILE I WILL PUT A DATE, KNOW THAT THIS IS HAPPENED MULTIPLE TIMES OVER THE LAST YEAR. USUALLY TWO TIMES A WEEK SOMETIMES MORE
