2000 Kia Sephia Engine cooling Problems

“I've had many problems with the catalytic converters disintegrating from within. I've had them replaced many times at least 3 or 4 times in the last 2 yrs the most recent was this summer about 2 months ago. I am having this problem again it begins to act like it's going to stall, then starts vigourously shaking, and it also loses acceleration speed. I'll be driving and all of a sudden it starts acting up and losing speed and it wont go any higher than 20 MPH or so. …”

“The sensor/gas level in the gas tank went out when the car had 53000 + or - on it and it cost us $300 to fix it. The driver's door doesn't seal. And now, as we left a store tonight, the flashing (yes flashing) check engine light came on again and the car is sputtering and clanging from under the bonnet. It is in the evening and a friday night. I opened the hood and it smelled funky/burnt. It was sputtering. The car currently has 72000 miles on it. I'll try to get it looked at in the morrow.”

“I have <45000 miles on my car (2000 Kia Sephia) and have had to have the front brakes replaced 3x and the back brakes replaced 1x. Also, when I turn on the AC, there is a loud noise from the front of the car. The car hesitates when trying to get up to speed. The car also feels like it is trying to pull something of great weight when driving at 55 MPH. The back seatbelts do not always lock. The dealer informed me that the seat belts are only to lock when the brakes are slammed or the vehicle is hit (so how is a child booster seat supposed to stay put when the vehicle is in motion?)”

“I bought a 2000 Kia Sephia on november 27, 2003. This car has the balance of a 100,000 mile powertrain warranty and only had 15,000 miles on it when I bought it. I noticed that it was using a quart of oil every 1,000 miles and after I changed the oil it was using a quart every 500 miles. I had already taken it in to the dealer for 15,000 mile servicing and took it back about this oil problem. The first thing they asked was permission to pull the heads, after which they informed me that the top of the motor was burnt and the only cause for this was failure to perform maintenance. …”

“While driving, the vehicle shut down and to restarted ten to twenty minutes later. By the time the vehicle was pulled over to the slow lane, the acceleration started again. (after a minute or two with no power) it sputtered before, while cruising. A carb cleanser was placed in. As the vehicle approached 35 MPH or 45 MPH, the acceleration restarted and the consumer was able to pull back onto the road.”
