2009 Kia Rio keeps stalling


Asked by Jan 07, 2016 at 09:21 AM about the 2009 Kia Rio LX

Question type: Maintenance & Repair

2009 Kia Rio (automatic, ~92k miles) keeps stalling while idling at a red light
and twice while driving (slowing to turn).  I have had the car checked at my
Kia dealership as well as at a local shop.  All diagnostic tests came back
clean with no indication of why it is stalling.  No warning lights come on
either.  Mechanics at both locations have driven the car and it didn't stall for
them at all.  I picked it up yesterday and 15 minutes later, it stalled while I
was sitting at a red light.  When this issue first started a few weeks ago, the
car started right away.  Now it needs a minute or two to start again.  There
have also been a few occurrences where the car will not start immediately
when we first get in.

I asked about fuel filter/pump and mechanics at both shops said they would
not replace anything unless they know the root of the problem.

Gosh am having the samr problem with my 06 rio5 ...by any chance did you find a sloution?


Yes! So frustrating! Kia and other garages could not detect the issue without a check engine light. Our light finally went on after about a month of random stalling, and at that point, the car was stalling during literally every trip. It was a nightmare. Check engine light test showed a handful of cylinder misfires and the guilty party-- the crankshaft position sensor. Our local garage replaced it for about $250 and we could tell immediately it was back to its normal driving confition. It's been two months and no further issues.


I've been having the same problem with a 2009 Kia Rio shutting down at stops. It's not showin any check engine lights either. Would u suggest the crankshaft position sensor?


Yes, I would. You could wait for a check engine light to be certain, but like I said, that took almost a month for our car and it was really stressful driving with it stalling more and more frequently. As soon as we got the check engine light, we went to AutoZone for the free diagnostic reading and that was the answer. We had it replaced and our car has been fine ever since.
