As soon as the car hits the mark of 60Kmiles, the owner has to make the decision. To keep it or get rid of it. If you decide to keep it, than prepare for more expensive tune Ups, or Preventive and Scheduled Maintenance Services. The squeaking noise means it is the time to replace the serpentine belt. It cost $30 and can be done by owner in 5 minutes, but from now you have to save some money, because between 60K and 90K the timing belt has to be replaced too with a new one. It is not the belt only, there is a kit with belt tensioners that cost $290 parts only.
For more information please read my tip:
When should i change the timing belt on my car?

After the timing belt most of the car dealers recomment to flush and change all fluids with the new one. Transmission oil and filter, coolant, brake fluid and more ....

If you have trouble locating the source of the squeak with the hood open, use a cardboard tube (e. g., paper towel roll core) as a stethoscope (caution - tie back long hair or other danglers first - you don't want something to tangle in the belt and yank your head into the engine!). A rhythmic squeak from the engine is likely a belt slipping. A steady squeal could be a bad bearing - check the belt tensioner pulley, alternator, power steering pump, and air conditioner clutch. The worst case would be a bad bearing in the engine or transmission.

On manual transmissions, a failing clutch throwout bearing could squeal when the car is not in gear and the clutch is not engaged but go silent under load.

Failure to keep running when the engine is cold can be caused by any number of tune-up issues, but it is more likely if you have extra load from a bad bearing. Check the usual suspects - air filter, spark plugs and wires, vacuum hoses, etc.

I have an 03 kia optima lx my car will cut off while I'm driving. Can you please tell me what the problem is. I would very much appreciate your input on this matter

this is caused by the crankshaft position sensor located behind the timing belt. this sensor cuts off the power to the spark plug so the car won't start. it happened with my kia and then everything went fine!

Pulley squeaks in 2007 Kia Optima

If it's a stand-alone pulley, it would have bearings which may be worn and about to fail. If it's a pulley on a component, like a power steering pump pulley, the component may need troubleshooting.

I own 2001 Kia Optima LX, it has 121k miles on it. The check engine light is on, and recently it jerks when moving. It does not pickup speed. It moves at 20-40 miles/hour, then after a while it picks up...

The locking steering wheel is a mystery to me , but the poor performance and check engine light make me think fuel filter / fuel pump.
I had a very bad experience with an 02 kia , only had 50,000 miles on it when the timing belt went and destroyed the engine , so........ i always mention to people with kia's to have the belt adjusted and inspected or replaced if you don't know how old the belt is.

replace your gas cap and clear codes, then wait and see if light comes back on, if it does you have a more serious problem like a fuel tank leak or a defective fuel tank pressure sensor.
