Call or contact the tire store / place of purchase. The store will be able to research the warranty or road hazard coverage details. Also, some tire stores such as; Discount Tires - will perform a flat repair such as tire patch - for free - even if you did not purchase the tires from their stores.

Any tire shop will check pressure & inspect the tires. You can also buy a tire pressure gauge and check it yourself. The recommended tire pressure is in your owner's manual and on the door jamb.

Check the vehicle owners and service / maintenance manuals for these details. Use unleaded fuel of 87 octane (regular). The engine oil recommended type and weight (viscosity) is SAE 5W30 or 10w30.

It sounds to me like you are adding coolant to the overflow tank and not the radiator. if this is the case then that is why you have this going on. (there is no "max line" visual on the radiator) and I aso believe you have a coolant leak that still remains undiscovered. Check the cooling pipe that go to the rear heater if it has a rear heater. Those pipes rust out just behind the R/Front tire. And yes, a bad stat is always possible. But my gut feeling says that is not your cause here.

The check engine light doesn't have to be ON to store a fault code.

Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

2. Amazon.com has the code reader for less than $20.00 dollars.

3.Re-post the dtc's in here " answer question " for further assistance.

Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.

Visit this site and see all the different sensors.

Is your plastic fender well touching the tire at all? Your brake caliper might not be bolted on tight and shifting ever so slightly, or the material its made out of is noisier than your used to. Another option could be something (little rock) wedged between the pad and rotor (it happens) and your hearing that rub.

My check engine light came on after I turned the ignition off but the car kept running and even idled. It took several tries to get it turned off. Please help me with this

Before we can do much you need to have the check engine light checked . We need to know why it's on . It might tell us everything we need to know .It can be done for free at most parts stores .
