I went into purchasing dealer for first oil change at 5100 miles, they flashed computer and loaded update Hyundai campaign 953 product improvement. About 50 miles after the recall was performed my car went into limp mode and is barely driveable. Car was also hesitating, and bucking a bit. Took it back to dealer they stated the code didn't apply to my car and flashed it again. It again went into limp mode after 50 miles or so. The recall is supposed to place the vehicle in limp mode due to rod bearing wear. My car has 5,400 miles on it and it now at a different dealer. Got information from that dealer regarding a tbs #19-01-002 and looks like engine replacement or wiring harness.

The lane departure warning sound does not have adequate volume and there is no option or software adjustment to increase this volume according to Hyundai corporate or my local dealer service department. With increased age our hearing ability may be less than when we were younger, mixed in with fluctuating road noise, this safety feature may not inform (audible sound notification to low) a driver of lane departure at the early desired notification time. In my opinion, this non ability to adjust the volume up or down on the lane departure safety feature is a gross engineering failure.

I bought my 2018 Sonata in January 2018. I have noticed that it tends to hesitate when making turns especially right turns. This problem occurs randomly when accelerating from stop or slow motion. Last week, I slowed down to take a near 90 degree left turn. The speed limit is 25 mph on this road. There was a vehicle in front of me - so, I maintained a safe speed and distance. After taking the turn, my car skidded very suddenly as I was coming out of the curve, and it was all I could do to correct it and prevent it from hitting a concrete pillar of the freeway passing above. The road appeared dry and the car in front of me did not have any problems. While I cannot rule out the presence of black ice, I was concerned that one of the wheel may have locked up either due to hardware or software problems. I took the car to the dealer today. The service department checked out car and they did not find any problems. I am reporting this incident since I noticed that some other owner complained of engine hesitation when taking turns. Perhaps, other owners may be experiencing similar issues.
