Question about Hyundai Sonata

1 Answer

Hi I have Sonata 2005 GL Model. Car stalls when I try to accelerate in the stop sign. Some times it stops even running at high speed in highway or at uphill position. Car is still under warranty, Dealer has changed the Crank Shaft Sensor, but still I have the same problem. There are no error codes in it. Last year I had the same problem, I used fuel injector cleaner and for 6 months I had no problem, but again I'm geeting the problem. What should I do.

Take it back to the dealership and tell them it's not fixed.. that the problem keeps coming back intermittently. Too many possible causes to discuss here. I've frequently seen drivability problems and no error (OBDII) diagnostic codes being stored/set. Ask the Svc Mgr to have a technician check the Throttle Position Sensor (TPS) and the MAF (Mass AirFlow Sensor). The TPS frequently causes problems with drivability, and doesn't always set a code.

Stalling when stopped fine when high speed


There could be some water in the fuel (especially with the weather we are having) and it wouldn't hurt to put some Heet (Heat) in the tank. It is designed to remove moisture from the fuel and can be purchased at nearly any retailer. Even if your 'service engine' light isn't on, there is likely a code stored in the 'pending' section of the engine computer. Places like Auto Zone (in most states) offer a free computer scanning service. Ask them to test it and if they get nothing, ask them to test the pending codes. If you get any codes, have them write the codes down so you can post them here for further explanation. Don't let them sell you anything. Most of the people working at stores like this don't know what they are doing and rely on the computer to tell them what to sell you.
