Does not accelerate, Check indicator

Kia Sorento 2004  150000 miles
My car's failure presented after a day of intense rain. When starting the engine, I found the car quite accelerated, at 1200 rpm, when the usual revolutions at idle speed are around 800 per minute. Even more, the Check indicator was turned on and the O/D light was flashing on the dashboard. I decided to start driving anyway as I needed to go somewhere nearby, and thinking it would normalize. But it wasn't like that, and even the following day the failure persists: even down the O/D light is turned off, the Check indicator remains on and the 1200 rpm are still worrying me. The accelerator is de… Read complete

Has your problem been solved? The same has been happening to me for two days.

Hello, Ford. My problem has been solved luckily. The car was left in the parking so that it dried and, after three days of the rain, it started working and everything was normal, the acceleration was working properly again. The only thing was that the Check indicator remained on. I started driving anyway and, after a while, the light turned off and nothing strange has occurred since then. My conclusion from this experience is that a sensor must have got wet and started failing and the car entered an emergency state. When I scan it, I will know which code error was stored. Hope it helps.

Buddy, it is the TPS sensor that is failing. It is the one that measures the position of the throttle body when pressing the accelerator. When the TPS sensor fails, the O/D light turns on and the vehicle does not accelerate.

Car hesitates then dies

Kia Sorento 2012 Kia Sorento  86000 miles
My kia starts hesitating when pressing the gas. When this happens, the 4WD light comes on and sometimes stays on then my car dies. Sometimes it's hard to get it started again and sometimes it starts up just fine afterwards. I have taken it tooi a Kia dealer twice. They replaced my computer module the first time and told me if it doesn't fix the problem they would need to change the throttle. Went I went back the 2nd time, they said there were no codes coming up so didn't do anything.

Same here- they said they had to download new software, but after a $380 bill, it still does this- happens 5 minutes after I start the car, every time!

Noisy acceleration

Kia Sorento 2011 sorento 115000 miles
When I press the accelerator, there is a rattling/knocking noise that fades once I'm at speed or if I accelerate hard. It will return if I press the accelerator lightly while on the road. The sound is coming from the front of the car. It doesn't change with speed or when I turn. Also, the oil light will flicker on for a second sometimes when I accelerate up hills

Accelerator pedal stops working

Kia Sorento 2017 2.4 20000 miles
Accelerator pedal stops working shortly after pulling away. Engine does not stall but stays at idle. Pedal recovers when I let up and press pedal again. Sometimes pedal recovers if pedal is kept at same pressure. This problem happens occasional, like weeks or days apart. Had vehicle to dealer twice however tech. Could not repeat problem.

I have to give gas for the car to start

Kia Sorento 2013 Sorento 123000 miles
When turning the key I have to give gas for it to start. Had the fuel pump replaced 6 months ago helped for a month or 2 then started doing it again. Otherwise drives well but when j turn on AC runs rough, which may be a different issue. But why do I have to press the gas pedal for it to start?

Over revving

Kia Sorento 2005 4x4 2.5 diesel 200000 miles
Had some white smoke on start-up although there was a lot more this time but it went after a while and then black smoke started coming out if the engine was under load, accelerating in 3rd or 4th. After about 5 miles the revs shot up to about 4k with no throttle with loads of black smoke out the back. They returned to normal after a few seconds and I drove on, set the cruise for about 55mph. Going through a town I had to accelerate from stop. Got into third and it starts revving again work more black smoke. I put it in 4th and dumped the clutch and this brought the revs back down. It died after a couple of seconds and now won't even turn over. I'm not sure if this is terminal or not yet. Anyone have any ideas what might have caused this?
