Open the full vehicle complaint log (all categories)IABOUT 2 MONTHS AGO, I WAS UNABLE TO START MY CAR. IT HAD A WARNING MESSAGE 'SERVICES REQUIRED. DO NOT SHIFT THE GEAR'. WE TOWED OUR CAR TO THE DEALER AND LEARNED THAT THE BACKSEAT FLOOD HAD STANDING WATER! THIS CAUSED THE ELECTRONIC SHORTAGE. WE PAID OVER $2000 TO MAKE THE CAR RUNNING AGAIN. IT LOOKS THAT THE RAIN GOT IN THROUGH DRIVER SIDE BACK WINDOW BECAUSE OF THE SEALING PROBLEMS. IT RAINED LAST NIGHT. I JUST LOOKED AT MY CAR. THE BACK FLOOR LIKES RIVER AGAIN. I AM UNABLE TO START THE CAR AGAIN. NOW WE FEEL THAT THIS CAR IS VERY UNSAFE. WE DO NOT KNOW WHEN THE RAIN WILL GET INTO THE CAR TO CAUSE THE ELECTRONIC PROBLEMS. WE ARE AFRAID THAT WE MAY BE TRAPPED IN A FLOOD IF WE DRIVE IT IN THE RAIN' WE CONTACTED THE DEALER LAST MONTH TO ASK THEM TO RECALL THIS CAR AND FIND THE REASON FOR THIS LEAKING. THEY TOLD US TO PAY ALL THE COSTS. WE DID NOT ACCEPT BECAUSE THIS IS OBVIOUSLY A MANUFACTURE DEFECT! WE ARE SEEKING YOUR HELP TO SOLVE THIS ISSUE BECAUSE THIS LEAKING MAY CAUSE MANY ELECTRIC PROBLEMS THAT HAS MAKE THIS CAR UNABLE TO DRIVE. I ATTACHED THE EMAIL COMMUNICATIONS WITH THE DEALER IN CASE THAT YOU MAY NEED THEM. THANK YOU AND I AM LOOKING FORWARD TO HEARING BACK FROM YOU SOON!
