Battery went dead one evening after absolutely no indications of a weak battery before. Drove it 40 miles round trip without any indication of a bad battery and 2 hours later it wouldn't start. Charged the battery overnight and still wouldn't start in the morning. Removed the battery and went and bought a new one and installed it. Back liftgate would not open anymore. The power switch for the liftgate is on, will not open with switch on the console, key fob, or switch on back lift gate. Have to climb into the rear and open with the manual lever on the liftgate.
