Open the full vehicle complaint log (all categories)I AM WANTING TO FILE A COMPLAINT AND NOT SURE HOW. I HAVE A 2011 NISSAN SENTRA WITH A LITTLE OVER 120,000 MILES AND HAD TO GET A NEW FUEL INJECTOR REPLACED TODAY. MY MECHANIC GAVE ME THE ORIGINAL PART SHOWING THE BACK END AND IT LOOKS LIKE IT ERODED AT THE ELECTRICAL END OF THE INJECTOR WITH NO APPARENT REASON. I BELIEVE THIS IS GROSS NEGLIGENCE ON THE PART OF THE MANUFACTURER AND WOULD LIKE TO SEE HOW TO GO ABOUT FILING A COMPLAINT TO GET THIS INVESTIGATED. THANK YOU FOR YOUR HELP AND TIME. *TR
