    As stated by other owners the brake lights come on and off I have had the bulb replaced several times. I wiggle the blub it comes on and off. This is a danger to cars behind me as the brakes lights are not working properly I believe there should be a recall as many owners are having and have had the same issue with this problem. My sister has a Hyundai not a Sonata had the same issue but her type of Hyundai was recalled for fault wiring. The Sonatas should be recalled also.

    Engine suddenly shutdown while driving in the middle of the road. Luckily, I was not on the highway. Had it towed to my mechanic and he told me that there was a class action lawsuit on these engines and that they were known to fail after 100,000 miles. I never got any notification about this problem. I am checking with the Hyundai dealership about replacing the engine.

    3 Months post oil change June 2022, oil plug fell out on highway and motor seized. Dealership advised motor no longer manufactured and recommended used motor supplier. Purchased a used motor with 80K on engine, had it installed in June of 2022. Dealership did oil change in December 2022, in February 2023 noticed oil smell and oil on the ground in driveway. Added 4.25 quarts of oil and started motor, attempted to locate the leak when noticed leak below motor. Turned off motor and found oil dripping from under car near the oil drain plug. Reached under car and touched oil drain plug with finger and plug fell out draining all oil to the ground. Had vehicle towed to the dealership, new oil change completed. Demanded the dealership install new oil drain plug, torque to manufacture specifications and apply lock tight to plug. Dealership stated they no longer remove the oil drain plug due to customer complaints and stated they only pump out the oil. When i asked them if that was a manufacture recommendation or their own they stated they started doing it due to multiple complaints from customers. Two engines 8 months apart, oil drain plug coming lose and falling out not a coincidence.

    This model does not have an engine immobilizer and the rear windows are not connected to the alarm system. My car was stolen in the middle of the day and there are no viable security measures for my car. This is incredibly dangerous and quite frankly ludicrous that Hyundai has not recalled the cars to install the proper security measures. I now have out of pocket expenses related to this incident and am still exposed to future theft because Hyundai failed and is continuing to fail ts consumers.

    My check engine light came on when I took my car to certified collision they ran a diagnostic and it came up as the timing in the engine is off. I looked up that there was recalls on 2011 to 2014 on this same problem.
