2017 HYUNDAI SONATA Complaints

The makes a weird shutter noise when accelerating and won't crank over 60. Loses power when turning or when going uphill. Sometimes has problem starting. Enging light came on twice blinking, once I changed the battery it went off and was working fine. Now it's back on again after a few weeks. Plus my oil tank still comes on and I've just received and oil change. I just bought the car in August of this year, dealership sold to me with a faulty battery.

Driving home car just shut off still had power to steer and brake but no engine. Pulled it off the main road and it leaked oil but still no engine. Already had the dealer replace the intake manifold at my expense despite hyundai knowing the plastic lever inside fails. We were lucky the snowplow was going the opposite direction as the weather was horrible as we got closer to home. I have a dead car in my yard waiting to have a dealer look at it. We could have been killed due to fault of engine.

HEV battery constantly states that the car needs turned off. Hyundai had to replace my engine as it just died and blew a hole in a pipe

The engine started knocking while I was driving around a lot of cars and while I was going to AutoZone to see why the check engine light was flashing on my car wouldn't accelerate and randomly started stopping and I was fearing for my life when I was going on the highway to go back home. For almost a year now I noticed the oil in my car started burning more and more like I would only drive 1k miles and it would already be done with, so I had to replace it. Hyundai knows this is a problem with this car because I called and asked them about the oil and told me specifically it's an engine problem once it starts knocking then you can come fix your car but want me to pay and fix the whole engine and work process.

Lost power steering in heavy traffic. Was able to move safely to a parking lot and stopped. A light came on with a steering wheel at the same time the power steering went out. Turned off vehicle and when started again no light on the dash and power steering was ok. After 2-3 more miles of driving lost power again with the light came back on. Was able to park safely. Started it the next day and all seemed ok but did not drive. 2 days later started ok and no light on dash, within 1 mile light came on then 10 seconds later the power steering stopped working. Was able to drive slowly to the mechanics and he confirmed that it needs a new module inside the steering wheel.

The drivers seat belt does not engage. The engine has been burning oil, misfiring, and even after thousands in repairs was returned to me by the dealership with continued misfiring. When returning the car back to the dealer service center days later after Hurricane Helene, the car continued to misfire and became so overheated the engine light was flashing. Upon calling for a tow, I attempted to raise the hood for the driver to locate the car, but the hood was so hot it burned my hand. The engine was so hot, I believe it was about to catch fire and would have had I not been able to pull over so quickly. Had I been driving on the Interstate, I have no doubt this car would have been on fire within minutes.
