Kia Amanti jerking problems

Filed Aug 16, 2018 · Airbags, Driver assistance · 70,000 miles · FL

Ever since I have owned the car, the airbag light has been on and does not go off until the car is off. The RPM gage has always been erratic when driving at normal speeds. The car lurches forward when at a stop light and while accelerating. The engine smells as if wires are burning and it seems increasingly hot, but the gage stays normal. The gas tank cannot be filled quickly, I have to trickle gas into the tank brake pads wear down constantly. I have already filed a complaint about the brake light switch being defective and this should be addressed before someone gets killed.

Just 2days ago my car started jerking real bad and also my transmission felt like it was stalling and the car was loosing acceleration power.then after a short hesitation the vehicle,while backing in the driveway accelerated and was hard to stop.today I noticed a small tremble in the transmission and my car almost went in traffic if I had'nt put the vehicle in neutral and applied force to the brakes,my vehicle was in motion on both incidents,I'm not afraid of my vehicle, but I don't want to cause or be in an accident.

Check engine light came on. Diagnosed as throttle position sensor. Car ran sluggishly for a short while, then that stopped, light went off. Today, light came on again. Backing out of a parking stall in a mall, the engine accelerated without touching the gas pedal, causing the car to lurch uncontrollably backwards, about ten feet. Fortunately, no pedestrian was behind the car, but if they had been, they would have been injured or worse. Called kia, they say there is no recall on this sensor, and it is not under warranty. From searching the internet, it appears this problem is widespread.

Tl* the contact owns a 2007 kia amanti. The contact stated that while driving at 10 MPH, the accelerator pedal was depressed but the vehicle jerked and failed to accelerate. The check engine warning light illuminated. The vehicle was taken to an independent mechanic who diagnosed that the ESC failed to function but the vehicle was not repaired. The vehicle was then towed to a dealer who diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 69,000. Updated 1/20/16 *ss the consumer stated the tranmission failure was the same as described in the recall, but the vehicle was not included.

Since purchasing my 2005 kia amanti air bag light has been on; the vehicle has never experienced an impact which would cause the airbags to deploy neither have any of the airbag components ever been tampered with. The throttle control of the vehicle is extremely sporadic and often causes hesitation, lurching, no acceleration, and even loss of all power. I have had the dealership update the ECM and the tps replace but the problem still persisted. I noticed the throttle body plate was extremely difficult to actuate so I then purchased another throttle body and replaced my older one. Everything functioned as should be expected up until approx. 3 months ago the issues started back up again. I noticed the throttle body motor had started to become increasingly hot to the touch indicating an excessive amount of resistance within the motor circuit. Being that the problem is recurring, I feel the issue is located either within the engine wiring harness or the engine control module and it, as well as the ruined throttle body motor, need replaced at the cost of the kia motor company. The issue can, and has, caused numerous accidents, stalling in heavy traffic as well as lurching and speeding away of vehicles. A major safety issue is present and needs to be addressed.

On 6 separate occasions the vehicle has slowed down and "chugged" out of throttle power while initially driving at speeds of anywhere between 35 and 65 MPH. If the vehicle does manage to keep driving, it does so in a very jerky way, almost like someone who does not know how to drive stick. I've found that the only way around this jerking is to drive the vehicle in sport-shift mode in a lower gear so that the rpms stay above 3000. Sometimes the vehicle is entirely unresponsive when the gas pedal is pressed, which (multiple times) nearly put me in a severe car accident on busy I-95 in both florida and philadelphia, pa. The check engine light has only ever remained on once, giving an error code p1614: "enhanced traction system engine control module malfunction." in the past, turning the ignition off and back on immediately has fixed the issue twice. Other times the vehicle needed to remain off for an extended period of time before the problem would clear up. The check engine light came on only 2 of the 6 times the problem has occurred. The first time it came on, it did not remain on although the problem persisted. Currently, the check engine light remains on although the vehicle has been running smoothly since the most recent occurrence of this issue which happened on january 8, 2015. I do believe the problem may be linked to the fuel injectors. I find that adding fuel system cleaner to a full tank of gas every other week helps me avoid having this problem.

When I start my car, the RPM accelerates high as it will go. Very annoying and loud. It does this most of the time some times when I come to a stop light and proceed forward, the car jerks forward as I accelerate.

When driving the engine suddenly quits, the car jerks, and the accelerator does not work. I have to coast to the side of the road and restart the car. This is a huge safety issue since there is no warning before this happens. Another issue is the engine revving upon starting. I have to hold the brake firmly because the car will intermittently lurch either forward or back without warning. I have also had the car try to lurch forward at a stoplight. I have to keep the brake firmly depressed since it is an intermittent problem. I cannot believe this model has not been recalled. It is a definite danger to driver, passengers, and others. I have read many complaints online with regard to this problem, but still no recall. I would participate in a class action suit. I talked with the dealer and kia and they are no help.

Engine loses power as though accelerator cable broke, also on start up car often lurches forward as if in gear. Took car to kia today and they state it is a known problem with their electronic accelerator hose, the housing that connects it to the engine melts and is no longer clipped to the engine often causing power loss because the connection is tenuous. The only fix they said would be to replace the part, but the cheap plastic they use will still melt and break off, causing another replacement needed in the future.
