When you are 300 miles from home, a warning light that follows an alarm sound while going 80MPH on I75 can make your heart stop. I know it did for me! A stop at a service station later, I was told the tires have the perfect amount of air in them and that apparently, the actual sensor is going. Come to find out, they are “expensive”, falling in the $150.00-200.00 range. Also, if I can deal with the alarm, I will be fine. Um noooooo I won’t! You can tell me a gazillion times it’s ok but I will still not be at ease until it’s off. I see a appointment with our mechanic in our very near future!
