Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Odometer Fraud. The contact owns a 1991 Porsche 911.

The dealer in Georgia had purchased and imported the vehicle from a dealer in Europe in 2023. The contact stated that after purchasing the vehicle, the dealer in Europe was contacted for additional records on the vehicle and the contact received documents related to the vehicle and the contact became aware that the vehicle had 100,000 additional Km/H than listed in the ad for the vehicle. The contact became aware that the mileage on the vehicle had been altered. The contact stated that the mileage on the documents from the dealer in Norway exhibited the correct mileage. The contact stated that the mileage had been rolled back when the vehicle was imported into the United States of America. The contact also found records of the mileage at the time that the vehicle was sold by the dealer in Georgia to the dealer in Utah and it was evident that the mileage had been tampered with. The contact stated that vehicle mileage was in kilometers per hour and indicated that the odometer reading was 233,000 Km/H. The contact stated that there was also an invoice for an engine rebuild at 91,000 Km/H however, the invoice from the dealer in Norway indicated that the engine rebuild was at 191,000 Km/H.

The contact then became aware that the vehicle title had been altered.

THE CAR BATTERY EXPLODED WHEN I TURNED THE IGNITION KEY. THE CAR IS ALWAYS PARKED IN THE GARAGE WHEN NOT IN USE. AS THE CAR HAS VERY LOW MILEAGE, ABOUT $15K MILES OVER A PERIOD OF TEN YEARS, AND I AM THE ORIGINAL OWNER. WHEN THE CAR WAS NOT IN USE THE CAR WAS CONNECTED TO A SMART CHARGER, MANUFACTURED AND RECOMMENDED BY THE CAR MANUFACTURER. (THE BATTERY WAS ALSO MADE BY PORSCHE) THE CHARGER WAS DISCONNECTED FIRST BEFORE THE CAR WAS BEING STARTED, LIKE I ALWAYS DO. AFTER THE EXPLOSION, MY GARAGE WAS FILLED WITH THE FUME FROM THE BATTERY, AND THE BATTERY FLUID STARTED POURING OUT ON THE GARAGE FLOOR. THE INCIDENCE WAS REPORTED TO DEALERSHIP IMMEDIATELY AND THE CAR WAS TOWED TO THE DEALERSHIP THEREAFTER FOR CLEANUP AND INSPECTION. SUBSEQUENTLY, A CLAIM/REPORT, INCLUDING PHOTO IMAGES OF THE EXPLODED BATTERY, WAS FILED WITH PORSCHE USA AND MY INSURANCE COMPANY. SO FAR PORSCHE USA IS CLAIMING THAT MY BATTERY WAS NOT MAINTAINED PROPERLY THOUGH MY CAR JUST HAD A 30K MILES SCHEDULE MAINTENANCE ON APRIL 20TH, 2010 AND MY BATTERY WAS MAINTAINED IN A WAY RECOMMENDED BY PORSCHE. MY QUESTION TO PORSCHE IN ARGUING MY CASE IS THAT WHETHER THEY REGARD AN EXPLODED BATTERY, UNDER NORMAL OPERATING CONDITIONS, IS ACCEPTABLE AND TO BE EXPECTED. IN A SENSE I FEEL FORTUNATE THAT THE EXPLOSION DID NOT RESULT IN INJURIES OR FIRE, WHICH WOULD BE CATASTROPHIC, CONSIDERING WHERE THE CAR WAS PARKED AT THE TIME. *TR

report

From owner reports, verbatim

Driving gently at 50mph down a smooth road the tire suddenly deflated; I pulled over to swap it out for the spare. On examination of the tire the inner side wall delaminated in 2 places, I could find no reason for the failure. There are no screws or nails or other damage that would explain why it deflated other than the sidewall delaminating. The car had an oil change 4 days before the tire incident and the tire was examined and found to be at the correct pressure. The rubber around the failures seems soft and tears easily. I have a matching set of these tires on my car, same brand and type. I did some searching and found a recall on this brand tire which describes exactly the failure I experienced; when I called the manufacturer they told me my tire does not fall under the recall.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
