Open the full vehicle complaint log (all categories)FRONT SUBFRAME COMPLETELY ROTTED OUT LOWER CONTROL ARM BECOME UNATTACHED, HAD TO REPAIR SUBFRAME AND ALL COMPONENTS, ABSOLUTELY A SAFETY RISK, MANY RECALL ON THESE VEHICLES BUT I DON'T UNDERSTAND WHY THEY DON'T HAVE ONE FOR THIS VEHICLE
THE FLOOR BOARDS ON BOTH THE DRIVERS AND PASSENGER SIDE FRONT HAVE RUSTED OUT. MOST OF THE OTHER METAL/ FLOORING HAS NOT RUSTED OUT LIKE IT HAS IN THESE TWO SPOTS. THE RUST DOES SEEM TO LEAD UP CLOSE TO THE SUB FRAME WHICH WORRIES ME OF THE INTEGRITY OF THE FRAME. THE FLOORING HAS RUSTED OUT TO THE FABRIC/INSULATION PORTION OF THE INTERIOR. ALSO OF CONCERN IS WHEN YOU ARE GETTING IN AND OUT OF THE CAR THE FLOOR IS SO WEAK THAT YOUR FOOT/LEG COULD GO THROUGH IT. IN TIME YOUR FEET CAN AND WILL GO THROUGH THE FLOOR WITH OUT WARNING.
THE FLOOR BOARDS RUSTED OUT ON BOTH DRIVER AND PASSENGER SIDES AND WE WERE NOT AWARE BECAUSE THE CARPET COVERED BUT YOU CAN FIT A FIST THROUGH EACH ONE! SHOULD NOT HAPPEN!!
RUST IN THE FLOOR BOARD ON THE PASSENGER SIDE. IT FAIL THE STATE OF NH SAFETY INSPECTION. THIS SHOULD NOT HAPPEN, MY TEACHERS SHOWED THAT THE NISSAN ALTIMA HAD THE SAME PROBLEMS.
DRIVERS SIDE FLOOR PAN RUSTED FROM THE INSIDE OUT WITH THE RUST RADIATING FROM A DRAIN PLUG. FLOOR PAN DESIGN ALLOWS WATER TO POOL INTERNALLY AND RUST FROM THE INSIDE OUT.
TL* THE CONTACT OWNS A 2004 NISSAN MAXIMA. AFTER INSPECTING THE VEHICLE, THE CONTACT DISCOVERED THAT THE DRIVER AND PASSENGER SIDE FLOORBOARD OF THE VEHICLE WAS RUSTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 120,000.
TRANSMISSION JERKS, SLIPS WHILE DRIVING ALSO BANGING SOUNDS WHEN YOU CHANGE GEARS THIS HAS BEEN HAPPENING FOR AWHILE I HAD TRANSMISSION FLUID FLUSHED, HAD THE ENGINE SPEED SENSOR REPLACED, NOW I WAS TOLD I NEED TRANSMISSION REPLACED 90,898 MILES HAD TO REPLACE UNDER CAR BODY BECAUSE IT ROTTED OUT
I JUST BOUGHT A 2004 MAXIMA ON AUGUST 2014.JUST BROUGHT THE CAR FOR A OIL AND THE MECHANIC TOLD ME THAT A HAVE A ROTTED FLOOR PANEL AN THE PASSANGER SIDE.WENT ON LINE AND NOTICE THAT I WAS NOT THE ONLY PERSON WITH THIS PROBLEM.CAN YOU HELP? I DONT FEEL SAFE IN THIS VEHICLE.I HAVE CHILDREN AND IAM AFRAID THAT THIS CAN CAUSE A ACCIDENT.
I NOTICED A SMELL WHEN I WAS DRIVING A COUPLE WEEKS AGO, SO I TOOK MY 2004 NISSAN MAXIMA INTO A LOCAL MECHANIC THAT I TRUST ON 6/26/15. AFTER PUTTING THE CAR IN THE AIR, IT TOOK HIM TWO SECONDS TO NOTE THE PROBLEM: THE FLOOR PANELS ON THE FRONT PASSENGER AND DRIVER SIDE ARE COMPLETELY ROTTING/RUSTING THROUGH FROM THE INSIDE OUT. YOU CAN SEE MY CARPET THROUGH THE BOTTOM OF MY CAR ON THE DRIVER'S SIDE. MIND YOU, THERE IS NO HISTORY OF FLOOD DAMAGE TO THIS CAR (I PAID THE $40 FOR A CARFAX TO FIND OUT), AND I LIVE IN TENNESSEE, WHERE WE DO NOT GET ENOUGH SNOW FOR SALT TO CAUSE ANY DAMAGE. I'VE DONE AN AMAZING JOB TAKING CARE OF MY CAR AND AM HIGHLY DISAPPOINTED WITH THIS SITUATION. I'VE ALSO DONE MY RESEARCH AND HAVE NOTICED MULTIPLE COMPLAINTS ON THIS ISSUE ON THE NHTSA WEBSITE, SO I KNOW I'M JUST ONE OF MANY 2004 MAXIMA OWNERS WITH THIS PROBLEM. THIS PROBLEM IS AN IMMENSE SAFETY HAZARD. I WAS TOLD I MIGHT BE ABLE TO DRIVE MY CAR SAFELY FOR ANOTHER MONTH OR TWO BEFORE I RISK MY SEAT FALLING FORWARD WITH ME IF I BRAKE TOO SUDDENLY. WITH AS MANY CUSTOMERS WHO HAVE HAD THIS PROBLEM AND THE FACT THAT THE DAMAGE BEGINS LOCALIZED ON BOTH THE DRIVER AND PASSENGER SIDES, RESPECTIVELY, THIS APPEARS TO BE A STRUCTURAL DEFECT IN THE 2004 MAXIMA THAT NEEDS TO BE CORRECTED TO ENSURE THE CONTINUED SAFETY OF THESE CARS' DRIVERS.
THE FLOOR PANEL ON THE PASSENGER SIDE IS ROTTEN THROUGH AND IT FAIL THE SAFETY INSPECTION. I AM DISABLED AND CAN NOT GET UNDER THE CAR TO TAKE PHOTOS.
FLOORBOARD IN MY 2004 NISSAN MAXIMA IS ROTTED OUT. PASSENGER SIDE IS ALMOST RIGHT THROUGH. MY MECHANIC SAID NO OTHER CARS HAVE THIS PROBLEM. OBVIOUSLY, IT IS A NISSAN DEFECT. SAFETY ISSUES ASIDE, NISSAN SHOULD STAND BY THEIR PRODUCT. WE PAY GOOD MONEY AND EXPECT TO GET WHAT WE PAID FOR. HOLD THEM ACCOUNTABLE TO FIX OR REIMBURSE THEIR CUSTOMERS! IT IS YOUR JOB AND RESPONSIBILITY TO PROTECT THE CONSUMER. THANK YOU. *TR
PASSENGER SIDE FLOOR BOARDS ARE RUSTED THROUGH. *TR
TL* THE CONTACT OWNS A 2004 NISSAN MAXIMA. WHILE HAVING THE VEHICLE SERVICED, THE TECHNICIAN NOTICED THAT THE FRONT PASSENGER SIDE FLOORBOARD WAS CORRODED. THE FLOORBOARD WAS REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 89,000.
I'M EXPERIENCING THE SAME AS EVERYONE ELSE WITH THE 02-06 NISSANS. MY FLOOR BOARDS ARE RUSTING OUT AND THESE COMPLAINTS ARE ALL OVER THE INTERNET. I'M AMAZED THAT THIS CAN BE IGNORED
THE UNDERSIDE OF THE CAR IS RUSTING AWAY, A HOLE ABOUT 12 BY 12 INCHES AND INCREASING BENEATH THE PASSENGER SEAT. IT MAY FALL THROUGH ONE DAY. *TR
WHILE VEHICLE IN FOR ROUTINE SERVICE, THE TECHNICIAN POINTED OUT SIGNIFICANT ROT TO FRONT PASSENGER FLOOR BOARD ON THE UNDERCARRIAGE OF THE VEHICLE. *TR
I HAVE EXTENSIVE RUST THROUGH ON BOTH DRIVER SIDE AND PASSENGER FRONT FLOOR PANS. IT APPEARS THERE WAS ORIGINALLY A DOUBLE LAYER OF METAL AND BOTH LAYERS ARE RUSTED WITH LARGE HOLES IN THEM. THE CAR IS BEYOND THE FIVE YEAR RUST THROUGH WARRANTY BUT THIS REALLY IS SEVERE AND DIFFICULT TO NOTICE SINCE IT IS UNDER THE CAR. THE RUST DOES NOT APPEAR TO BE FROM THE OUTSIDE BUT APPEARS TO BE FROM THE INSIDE OUT. I DO NOT KNOW WHAT WOULD CAUSE THE RUST TO BEGIN FROM THE INSIDE BUT SEEMS TO BE A DESIGN DEFECT TO ME. I WILL TAKE THIS UP WITH NISSAN AS I BOUGHT THE CAR NEW, BUT I DOUBT THEY WILL OFFER TO STAND BEHIND THIS, SINCE THIS IS EXTREMELY DANGEROUS AS IT IS POSSIBLE FOR FUMES OR ROAD DEBRIS TO COME THROUGH THE CARPET AND INTO THE PASSENGER COMPARTMENT. I AM NOT CERTAIN WHAT THE MILEAGE WAS WHEN THIS BEGAN BUT THIS AMOUNT OF RUST DID NOT BEGIN RECENTLY. I SUSPECT MAY NISSAN MAXIMA'S ARE AFFECTED BY THIS PROBLEM AND THERE SHOULD BE SOME SORT OF SAFETY NOTICE TO CURRENT OWNERS TO MAKE THEM AWARE OF THIS PROBLEM.
