2015 TLX. 3 times in the span of a week turned the car off and returned a short time later and car would not start. All 3 times had to jump start to start. Mechanic checked battery and it rated at 440 CCA tested at 395 CCA. Mechanic performed different tests to determine if systems were drawing on battery and none found. Then went to dealer who checked for a day and found no issues. Dealer denies any issue with hands free blue tooth draining battery.
