ON 2 SEPARATE OCCASIONS, APPROXIMATELY 3 MONTHS APART WHILE IN HARD ACCELERATION ATTEMPTING TO MERGE ON AN INTERSTATE ON-RAMP, VEHICLE BEGAN TO SHUDDER VIOLENTLY AND LOSE POWER. IN FIRST INSTANCE, I WAS ABLE TO MERGE IN THE LEFT LANE AND LET OFF THE ACCELERATOR. AS VEHICLE COASTED, THE SHUDDER SUBSIDED AND WITHIN 1 MINUTE STOPPED ALL TOGETHER. IN THE SECOND INSTANCE, WHEN THE VEHICLE LOST POWER, TRAFFIC CONDITIONS WOULD NOT ALLOW ME TO MERGE AND I WAS FORCED TO COAST ALONG THE SHOULDER OF THE ROAD UNTIL THE SHUDDER SUBSIDED AND POWER WAS RESUMED. IN NEITHER SITUATION, DID THE VEHICLE GO INTO SAFE MODE OR THE CHECK ENGINE LIGHT APPEAR. VEHICLE SIMPLY RESUMED NORMAL OPERATION. *TR
