Hi I have a 2013 Kia Sportage AWD 2.0L Turbo Diesel Auto. When driving the the accelerator pedal dies.
I can be driving a long and when I press the accelerator nothing happens - no revs the car just idles - as if I never pressed it. This has been getting worse over the last 18 months. In the beginning the car would go into limp mode and I could still drive it a bit but now the car just comes to a stop.
I have taken it to Kia and they reset the computer and could not get it to fault. About a week later it happened again and took it back. They replaced the EGR and it still did the same problem. They ended up replacing the accelerator pedal. This worked well for 5 weeks and then the problem came back intermittently. They said don't bring it back unless it happens all the time. Looks like the new accelerator masked the problem for a little while. So kept it for another couple weeks and after a bit of rain it came back worse than ever. No lights on dash but car does not go into limp mode. I just have to quickly pull over while I still have momentum.
Could it be the ECU or the actual wire/cable that connects the accelerator to the ECU needs replacing? Could corrosion on the connectors to the ECU cause this issue?

Any help would be greatly appreciated.

Have the throttle body serviced. I had a Toyota Rav 4 that had a similar problem. wife drove the car to work, on the way back she stooped to talk to a neighbor when about to drive off it went into limp mode. Had the throttle body serviced and problem went away

Diagnostics is what we promote here - just because something worked for you doesn't mean its the remedy.

In your case going into limp mode would have set an error code, and that error code would be used as the starting point in the diagnostics.

Read the error codes and post them here - the dealership should have read the codes instead of waiting until the intermittent problem became permanent.

Maybe @gee6, the diesel specialist, could offer advice.
