2007 Kia Optima Electrical system Problems

“Ever since we got this car it has been in 2 accidents due to the rain, when I started to look into what was causing this problem I noticed there is a hole in the plastic right below the oil filter. This allows water to get on the engine causing it to short power for the car. This in return causes the power steering to cease up making it nearly impossible to control the car, hence why it has been in two accidents; one that put my mother in the hospital a few years back. The last time this happened was yesterday but enough is enough, this flaw is a deadly problem.”

“I was in a crash and I have to say that this is a problem. After I received my car back from the body shop the car has been malfunctioning ! The 2.7l has stumble on and at acceleration the failure is the throttle position switch this is a safety problem for all driver's that drive a 2007 Kia Optima. The malfunction occurs five times in one day. This problem may cause severe or fatal injuries to the occupants in the vehicle. Nothing was done to correct the failure and the old throttle position switch is available! …”

“As I was driving on the freeway today the car suddenly went from a speed pf 65 to 20 MPH in the passing lane. I suddenly turned on the emergency lights to let the cars behind me know that their was a problem. Thank god I was hit and was able to pull the car over on the ramp. I called to have the car towed but in houston (this labor day) no one is able to look at the car so I was able to get it towed to auto zone. They ran a diagnostic and the tps (throttle position sensor) codes appeared. I was told only Kia carries the part. …”

“I bougjt this car in 2014. I have replaced both low-beam headlights, twice, a brake light, both rear blinkers, a front blinker, as well as both highbeams. I have never replaced even half the number of lights in the entire lifetime of ownership of any vehicle I have owned in the past. This is an obvious recall issue based on safety as well as quality if Kia cared. When the lights are working I have to drive with my high-beams on and I never get flashed or pulled over. It is extremely hard to see vs. Any other vehicle. I have had many friends and family in the car and have shared the story. …”

“Had ongoing issues in which the car got stuck and would not accelerate past 25 MPH, even if I floored it. I had to take my foot completely off the gas pedal, wait a few seconds (by then the car would be down to 10-15 MPH), then try to accelerate again, which sometimes took several tries. I was very worried about getting into an accident when this happened because there was no warning and if you suddenly stop moving at the speed of traffic with no indication you are slowing down, you could easily be hit. In one case, I was trying to pass a slow-moving vehicle going 25 in a 40. …”
