Stalls

Kia Sportage 2002  120000 miles
My car usually starts working properly but suddenly stalls. It loses power and the dashboard turns on and off. I've already changed the pump, the injectors, the battery but the problem is still there. Can anyone please help me?

Check the catalytic converter.

I’d check my alternator. Those sound like alternator issues. Your alternator should be giving out 13VDC - 15VDC. Start your car and unplug your positive post on your battery. If it continues to run it’s not your alternator. If your car slowly dies and loses power then you need a new alternator.

A/C must be on for engine to run correctly

Kia Sportage 2006 hatchback manual 105000 miles
I have had EGR valve, throttle body and associated sensors changed but now find that the A/C must be on for engine to run smoothly. If I turn it off, engine hesitates and mis-fires

Could be the clutch sensor. My kia garage done all what you have done and concluded that there is wear on clutch which makes it stutter in first 2 gears. When AC in on engine runs st a higher level and has no problem. They are replacing clutch sensor on warrenty to hopefully solve problem

Start or Fuel issue

Kia Sportage 2000 Sportage 120000 miles
I have a 2000 Kia Sportage I replaced my fuel pump and tank and everything seamed fixed and now it won't start as if no fuel I disconnect the fuel pump and crank a few times and it almost fires over for a second, then I reach back and plug it back in and crank and it won't start. I finally sprayed starting fluid down the throat and it tried to start and finally started. Once it is running stays running without any misfire or hesitation, but you never seam to know if it is going to restart after turning it off for like 30 minutes. If I turn it off, then turn it on seams like no problem, but… Read complete

Winding noise from middle rear and burning rubber smell

Kia Sportage 2005 Sportage 220000 miles
I got my 2005 kia sportage EX used for 1700 last year. There is a distinct winding type noise emitting from the middle rear of the vehicle that gets louder sometimes with acceleration. I also have been smelling a burning rubber smell when I drive on the freeway and go 60-70 mph that doesn't go away till after being shut off and bsb parked for a minute. Could my transmission be starting to go? After I first got it, I would sometimes get a check engine light and the codes that came up were related to something with the wiring of the solenoid or something like that, but the check engine light has… Read complete

In higher revs, car acts like clutch is in.

Kia Sportage 2013 2TDI Diese 30000 miles
As I drive and accelerate at higher RPM the engine revs up as if the clutch is in and doesn’t accelerate. Car will accelerate and increase speed at around 2000RPM however. Cruise control also doesn’t switch on since this issue started.
