Check engine light is off and on frequently.
Check engine light flashed, car shook, and I had to have the transmission rebuilt.
Airbag light comes on and goes off at random.
Tire pressure light accurately indicates low tire pressure, but why do tires keep losing air.
It has been a great car otherwise, handles well, and is fun to drive.
Why do tires keep loosing air? 1. Small leak at the valve insert. 2. Small leak around the valve stem. 3. Small leak at the tire/rim mating surfaces. 4. Porosity of the tire materials. 5. Porosity of the rim materials.
Valve inserts are $2.00 for a pack of four.
Aluminum rims don't hold air as well as steel rims do. Cast aluminum is porous like a sponge. If that is the problem the inside of the rims can be coated with paint to improve air tightness.
Air pressure changes with the seasons as well. Say it was warm in September and suddenly gets cold in October tire pressure will drop even without a leak. The air contracts more than the tire. Blow up a baloon and put it in a freezer for a few minutes. See what happens.
