has anyone had a problem with the engine control module on a Sonata Limited
I have a 2011 Hyundai Sonata LTD. three weeks ago I tried to start my car
and it would not start. The lights on the dash board came on but when I
pushed the start button everything we went off. I could not turn the steering
wheel or put the car into another gear. I brought it to a dealership and they
said my battery and starter needed to be replaced. I paid them $695 to
replace a starter ( i am a girl so of course it cost more) and I replaced the
battery. Everything was fine for about 5 days than I noticed a change in the
way the car drove. I would put my foot on the excelerater and the RPM"s
would go up but the increase in speed would lag or not go up at all. Now the
car is not starting again. The lights go on but when I push the start button
everything shuts down. Can this be the ECU (or Powertrain control
I would have the alternator load tested. Check the battery terminal wires & terminals for being tight and corrosion free with good connections at each end. Not know the cost of the starter at the dealership off hand I would still think you paid dearly for it.
battery could have a bad connection
I’m going through this now. EXACT same scenario, same car. It wouldn’t start one day. Replaced the battery and starter. Seemed fine for a day. Engine light came on. Mechanic who did repairs looked at it and advised to take to Hyundai Dealership. Next day on the way, there was a pop from the engine, knocking, lost all acceleration power. I was going 70 mph on I-40 at the time, in the center lane, in rush hour traffic. Barely made it to the shoulder without getting mowed down by cars and big rigs flying around me. Nevermind the hazard lights that were immediate turned on. 30 minutes later, power is restored. A friend calls and tells me about an engine recall that is subsequently verified through Hyundai’s website by entering my VIN. My car is affected. But the dealer wants $1330 for a new ECM because it passed their “audible inspection.” Another mechanic and another dealership says bs. The engine needs to be replaced. Even with a new ECM, it’s still at risk for engine failure again in the future and a full replacement includes what? A whole new ECM. Curious to know how your situation played out. I, too, am a woman with a 2011 Sonata Limited Edition and feel these are classic intimidation tactics. There’s a whole class action lawsuit about it for those who paid for the repairs. HUGE settlement. Was there any final resolution for you?
