P1326 knock sensor, limp mode, afraid of engine failure

This isn’t even my car but here I am working on it. My wife is a nanny for this lady and she needs all the help she can get. Her car went into limp mode and now I know a great deal more about Kia/Hyundai knock sensors than I care to. I have no clue if the new sensor fixed it, so here I am. Fortunately the dealer confirmed that her vin is not one of the exploding 2.4 engines.

Edit: meaning it’s a regular 2.4… not with the fire hazard thing. That may not apply to the 2.4 though.

It’s best to have this checked out by a mechanic to diagnose the cause of the warning. They can perform tests on the alternator, electrical system, and battery to pinpoint the issue.

Hello C, P1326 CODE indicates a problem with the Knock Sensor Detection System (KSDS) in your car. The KSDS monitors for excessive knocking or vibrations in the engine, which could be a sign of internal damage.

I totally get it! I’ve been there too. My neighbor’s car went into limp mode, and I ended up learning more about knock sensors than I ever wanted to. It’s a lot to handle, especially when it’s not even your own car.

The good news is that if the dealer confirmed her VIN isn’t one of those with the exploding 2.4 engines, you’re on the right track. I remember dealing with a similar issue, and after replacing the knock sensor, it took a bit of driving to see the results. Keep an eye on it and give it some time.
