Filed Oct 12, 2023 · Acceleration, Seat belts · MI · crash

My vehicle speed up and slow down all that itself. It will not maintain speed even with my foot steady on the gas. It will not accelerate, but the major problem is my seatbelt gets stuck all the time I’m afraid to get buckled. I am unable to remove my seatbelt multiple times so now I have buckled my seatbelt behind me so I can start getting tickets. I’ve gotten like four tickets because I’m scared to be buckled that it’s not gonna come on down when I need it to be I’ve got 40 bought tickets. I was going about 20 mph when I went to the brakes for my vehicle accelerated by itself crashing into a pillar at the mall. I did call the police.

I've seen in other forums about engine recalls. I was never notified and the engine in my car disintegrated. It was replaced with an engine from a wrecking yard. This should be covered by manufacturer. I had issues with the brake lines rusting out. This should not have happened either. Not being able to service the transmission and arguing with the dealership about this should be replaced by manufacturer!

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! I really thank that this is found to have a defect that affects safety and the automakers need voluntarily announce a recalls on all the 2007 kia optima that have the same throttle position switch as this vehicle.

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 was so scared for my life and I don't want to ever be in that position again because my kids were in the car. I was reading complaints on several websites and it seems that this has been an ongoing problem for a while. It's sad that kia hasn't of yet issued a recall to fix this problem. Something has to be done about this as this was wake up call for me I can honestly say I thought I was going to lose my life when my car dropped dawn from speeds of 65 to 20. I have had problems with the car losing power but it would quickly regain power but nothing of this instance. Very scary situation for not only me but for the sake of my children that were present in the vehicle. Http://repairpal.com/faulty-throttle-position-switch-355 I just researched and found out they released a better performing part but others are still continuing to have the same problem even after the replacement part. Kia could of at least notified its customers of the problem rather than many of us finding out the hard way. There needs to be a recall immediately. The next person might not be so lucky.

While parking 2007 optima I was unable to put the vehicle in park or take out the key. The shifter linkage and cable had broken. I used the emergency brake to keep the vehicle from rolling. I took vehicle to dealer (summit kia, waterford, mi) they replaced the vehicle shifting linkage at a cost of $750.00. The dealer stated the cable broke and when I asked if the part was defective they stated that it was not unusual to have to replace this on the 2007 kia optima. The vehicle has 108,000 miles. In 40 years and many vehicles I have never had this go on any other vehicle I owned.

On two occasions (to date) my kia optima has become inoperable - unable to put the car in drive or reverse. The first occurred during the winter in february 2010. After one of many snowstorms this season I was driving on a plowed road then encountered an area where there was only room enough for one car to pass. When I pulled over to allow an approaching vehicle to pass my car was in about 8-inches of snow. While moving the transmission selector between reverse to get out of loosely packed snow I found I could no longer get the car into a drive gear ' forward or reverse. The car had to be towed because it was no longer operable and was causing a road hazard for other vehicles. The dealer claimed snow caused the shifting cable to detach from the gear selector. The dealer, holly kia, reported the problem was repaired by reattaching the cable to the selector. More recently my son was operating my vehicle on or about july 6th, 2010 ' a 100+ degree day. He reported that he was in reverse to move the car to another parking spot in a car dealership and the car could no longer be shifted into any gear' again. During this instance the car was on a steep incline and my son was fortunate to be able to maneuver the car around other parked cars but the car had to be coasted to the bottom of the grade in order to be safely parked. After the second instance, the car was again towed back to holly kia for repair - holly kia is now replacing the shifting cable. The holly kia service department claims this problem with the 2007 kia optima as a manufacturing flaw. My concern is, after the repair can the car be trusted and operated safely ' both incidents left the car in a very compromised state and a hazard to other vehicles (moving and parked).
