I have had the ABS checked by Hyundai dealership per recall and they told me there was no issues, but Iâm having a lot of problems with accelerating, and it shifting gears, I donât think the system is really diagnosing, whenever I turn my car on sometimes it will do a diagnostic read, but it canât send data, and it will take a while for the system to reset itself. It does smell like my car is smoking and I will have to physically roll my window down and/or poke my head out the window to make sure itâs not smoking. Iâm checking my temperature gauge in my car to make sure it id within normal range. And when the check engine light comes on, sometimes it will come up and will blink for a few seconds and then disappear. Then I will go to OâReillyâs or Advanced Auto Zone to get a reading the common codes that have come up were P0401, P0442,
