Shunt Malfunction Signs. If your child becomes very ill (persistent vomiting, extreme sleepiness, severe headache), seek medical assistance immediately. Call your childâs doctor if you think that your child is having a shunt malfunction based on the symptoms described above. Remember that you may see only one or two warning signs at a time.
Replace the tires at least every 6 years. If you're not sure, the minimum replacement time that is recommended by the NHTSA is six years regardless of use, with 10 years being the maximum service life for tires. Check your owner's manual for specific recommendations related to your car.
Many replacement tires, especially the all-season ones that come standard on a car, minivan, or SUV, have a prorated mileage warranty. Itâs based on how long the tread on a tire is expected to last. For the tires we tested, it was usually between 40,000 and 90,000 miles.
