| Description of the problem | Run flat tires needing replacement only after 2 years of owning the car. 2 blowouts on the freeway due to no direct tire pressure sensor to alert us of the flat tire. The light only goes on after the tire is blown. The first blow out, i drove it directly to the dealer. Total cost of replacement $350 for tire. I then had problems with the "indirect" tire sensor light coming on. I called the dealer back, he told me to ignore the light because the cold outside was causing it to go on. I drove it back anyway, they checked the tire pressure, put some more air in and sent me home with my sensor light still lit. I took it back to the dealer a few weeks later, they said it was a leaky valve. They replaced the valve, filled the tire with air and sent me home. Less than 5 days later, another blowout on the freeway. I drove it to the nearest tire store. They could not do the repair because the tire would ruin their machine. "it's harder to break down" and take off. I was sent to another tire store. They were able to remove the tire and replace them with regular tires. Now, i don't have run flats anymore, but i don't have the excessive cost to keep replacing these expensive tires. The dealer told me at the time of the purchase that it was a "dream" for mom's transporting kids because i wouldn't have to change to a spare if the tire went flat. That the care was safer than safe. The manager of the service department also told me i was lucky that i got 40,000 miles out of them. Both tires blew out on the freeway, i rolled the car in at 25 miles per hour, on the rim, with my kids in the car. I did it safely with my driving, not because of the run-flat tires. I will never purchase another car with run-flat tires. They didn't tell me how expensive they were to replace and that i would need to replace them so frequently. Also that the tire sensor is indirect. I didn't even know when the tires were just getting low, only when completely flat. |
