Transmission malfunction while driving, so scary.
The engine oil keeps going down every couple hundred miles and needs to be topped. Embarrassing doing this every month.
MY CAR WILL TURN OFF AND SHOW A POWERTRAIN FAILURE. I HAVE TO WAIT 10 MIN TO RESTART THE CAR. IT HAPPENED SEVERAL TIME AND KEEP ON TAKING IT TO THE DEALER AND THEY CANT FIX IT. THEY PROMISE WHEN THEY WERE GOING TO REPLACE THE COMPONENT FOR THE FUEL PUMP (LAST RECALL) I WONT HAVE THE PROBLEM ANYMORE. I TRIED TO TALK TO THE MANUFACTURE TI HELP ME FIND THE PROBLEM, BUT SINCE THEY CANT REPRODUCE IT THEN IT MY PROBLEM. THE ISSUE DOESNT HAPPEN OFTEN MAYBE ONE A MONTH. BUT ENOUGH TO BE SCARY. WHEN THE PROBLEM HAPPEN, MY CAR IS ON A LOW SPEED. LIKE MY KIDS CAR LINE IN SCHOOL. OR WHEN I PULL OF A PARKING SPOT. ITS THE SLOW MOTION. EXIT OF A HIGHWAY AND ALSO RED LIGHT.
