Mitral valve prolapse differs from mitral valve stenosis. In mitral valve stenosis, the mitral valve is stiff and constricted. In mitral valve prolapse, the valve slips backward due to the abnormal size of or damage to the mitral valve tissues. For most people with mitral valve prolapse, the cause is unknown. Mitral valve prolapse can run in families.
Toyota Warranty. Following the massive global recall scandal that Toyota suffered in 2009 and 2010, Toyota increased their warranty coverage from 3 years to 5 years or 100,000 miles on all new cars. As with many manufacturers, there is no limit on the carâs mileage for the first year.
The hybrid components usually have their own warranty, which is separate from the powertrain coverage. These vary by automaker, but some are quite extensive: Hyundai offers lifetime coverage and unlimited mileage on its hybrid components, while Toyotaâs parts are limited to 8 years and 100,000 miles.
