I have experienced problems with both CV Joints/drive axles. This problem is very common with the Storm. Not a big deal really.
I have a slight power steering fluid leak. Not a big deal either.
It tends to run hot every once-in-a-while. It makes me wonder if there is a slight Radiator leak or maybe a loose hose somewhere.
This is a great car! It gets superb gas mileage, and it flies! Would definitely own another one. It has been described to me as handling like a Corvette.
This car is seriously underrated by many people. The whole "Geo" badge is supposedly a sign that it's slow. Not true! The lady I bought mine off of was selling it because she was afraid she was going to get a ticket because it was too fast for her.
My storm had the same problem with over heating too. My radiator wasn't clogged or leaking, it just wouldn't flow right. I replaced the top and bottom radiator hoses, removed the thermostat, and got a radiator at a junkyard for 35$. I also put in some stuff that stops over heating from auto zone that really works. That stopped the problem and it's ran cool ever since.
