If your car is frequently slipping when it shifts gears, it probably means the transmission is about to go.

No. 1: All problems not big problems

Your used car may have failed you on a road trip and left you stranded on the side of the road, but this does not necessarily mean it is time to take it down to the junk yard.

Electrical, battery and overheating problems frequently can be taken care of with relatively cheap and easy repairs to put you back on the road.

If your car overheats, it is usually something related to the engine cooling system. It could be something as simple as a leaky hose. But just be sure to resist the urge to drive your overheating car, or it could be the last trip you ever take in it, Larsen said.

Sometimes your car might die on the road and sound like it is out of gas when you try to start it even though it isn't. This could mean that the fuel pump has gone out. Depending on what kind of car your drive, according to Larsen, it can be very cheap or very expensive because some fuel pumps come as part of a larger unit.
