SECOND TIME THIS HAPPENED...FIRST THEY SAID BATTERY...WHILE DRIVING, INDICATING WARNING LIGHTS ON DASH START BLINKING (ABS, CHECK ENGINE, TRACTION, AND OTHERS), THEN THE ENGINE GOES INTO LOW HEAR AND STAYS UNTIL THE VEHICLE IS TURNED OFF AND BACK ON. DURING THESE EPISODES THE SPEED ODOMETER IS ERRATIC. ALSO WHEN IN THIS STATE, THE REVERSE GEAR DOES NOT ENGAGE. WHEN THIS STARTED IT WAS A ONCE A MONTH PROBLEM, THEN WEEKLY, NOW IT HAPPENS DAILY/HOURLY. IT STARTED AT APPROXIMATELY 40,000 MILES. THIS HAPPENS WHILE DRIVING ON CITY STREETS AND HIGHWAY, MOST OF THE TIME AT STOPS AND LOWER SPEEDS BUT DOES HAPPEN ON FREEWAY TOO.
