2016 Hyundai Sonata owner complaints

My car is involved in the class action lawsuit because of engine failure and fire with my 2016 Hyandia Sonota. I have concerns with the above issue because of knocking in the engine and using 1 quart of oil every 400 miles. Hyandia extended the Power train settlement for life time. Yet, they denied to do anything about my car because or 98,700 milage. Dealer said only way Hyandia will do anything if the engine goes out. Hope it just goes out instead of catching fire. Need help, if you settle take care of the customer. Should take care of the customer before settling .

My 2016 Hyundai Sonata experienced a sudden engine failure while in operation with no prior warning lights or symptoms. The engine seized unexpectedly, creating a safety risk. This failure appears consistent with known engine defects affecting Hyundai Sonata vehicles of this model year. Hyundai Motor America denied my claim without addressing these known defect patterns.

My 2016 Hyundai Sonata is sitting at the Red Hoagland dealership in Winter Haven, FL after the engine started knocking. Rather than continue driving it and risk an accident with our 19-yr old child driving it, or risk worse damage to the engine, I had it towed to Red Hoagland service department. This occurred less than a week after we had it at the dealership for the third and final oil consumption test. These tests were being conducted as part of Hyundai’s process to identify the known engine issue with this model. Each 1,000 mile test revealed that the engine was consuming approximately 3.5 quarts of oil per 1,000 miles (approximately 1 month timeframe). Despite the results of the tests and now the engine failure, Hyundai has denied the claim on the lifetime warranty of the engine. Their

It burns through about 2.5 quarts of oil every oil change and Hyundai says that normal... That's far from normal.

Oil pressure sensor failure caused oil to leak into the injector harness damaging components and engine shutdown. Because this was a sudden engine shutdown and safety-related loss of motive power caused by an oil pressure sensor failure this presents a safety risk

When I drive my sonata, sometimes the gears do no switch. I can drive on a flat or inclined surface and it will act up. We've taken our car several times to the dealership for diagnostic testing to see what's going on. But when the car is connected or the serviceman drives the car, the car will switch gears and nothing is found on the diagnostic test. We currently driving a few states over and our car is not switching gears at times, affecting the gas mileage. My husband and I will decelerate until gears switch and then accelerate again.

On November 10, 2025, my 2016 Hyundai Sonata Hybrid (VIN [XXX] , approximately 150,000 miles) experienced a sudden loss of power while I was turning right and accelerating into traffic. The vehicle immediately entered limp mode with flashing warning lights and audible alerts. The vehicle lost normal propulsion and could not accelerate properly, creating a dangerous situation as it was blocking a traffic lane. I was forced to limp the vehicle into a nearby parking lot to get out of traffic. The vehicle was not safely drivable afterward and was towed home. A few days later, the vehicle was towed to Murdoch Hyundai in Lindon, Utah, for diagnosis. The vehicle was found to have diagnostic trouble code P1326, which Hyundai identifies as activation of the Knock Sensor Detection System (KSDS) re

At stop sign to turn left, started and steering wheel would not turn. Felt like loss of power steering. Fortunately, no other cars around, I put gear in reverse to back up before hitting ditch on other side of road. I turned off car, restarted and wheel worked. Stopped on major highway to turn at light, happened again. Manage to get car to pohanka Hyundai svc dept.. Next day, was told it was a sensor. Car drove ok for a couple of days and then happened again, two different times. Waited until after christmas to call pohanka but decided to research recalls on this model. Dec 30th, stopped to turn left onto street, steering locked up, almost went in ditch crossing over 2 lanes. Cut off engine with key, restarted car, backed up and managed to get off road to keep from being hit by onco

Vehicle exhibits sticky steering and engine has stalled 3 times. Steering is very difficult to control as it sticks severely when trying to steer or maneuver the vehicle on any local road or highway. Vehicle has stalled 3x already when coming to a complete stop. Vehicle shakes when brake is released moving from a complete stop.

Wind deflector came loose on highway after recall was performed. The wind deflector was originally reattached in 1996 shortly after purchase. The recall doesn't take into account that the manufacturing issue may of been previously repaired. I believe when the "recall" was performed(2020) the lack of removing the previous adhesive created a weak bond enabling the wind deflector to become detached. Attached is a copy of the recall instructions which contains no step to remove previous adhesives or check for previous repairs; only the use of alcohol to remove dust or particles. Hyundai corporate followed through on an investigation Case Number #[XXX](December 2024) finding that the recall was performed and they had no ability to investigate the proper method for subsequent repairs.

I was driving to work when my car stuttered then reduced power allowed me to pull to shoulder of the road at the same time my check hybrid system light came on with all others on dash. Car would not restart. Had it towed to the dealership where I’m told they will diagnose next week. I researched on several forums and this is quite a common issue with this model of car in various years. My car only has 61k miles and this is quite troublesome.

I am writing to bring to your attention a critical issue affecting my 2016 HYUNDAI SONATA 4 DOOR SEDAN, that warrants investigation and public awareness. Hyundai cars are currently plagued by ENGINE OIL CONSUMPTION PROBLEMS that ultimately lead to ENGINE FAILURE, due to there being NO WARNING LAMPS, MESSAGES, or OTHER SYMPTOMS OF THE PROBLEM PRIOR TO THE FAILURE. This is a concerning issue that remains largely unknown to most customers. When these issues arise, car owners such as myself, are often left with uncooperative dealerships that either deny the problem or offer minimal assistance. Even Hyundai corporate and extended warranties fail to provide adequate support, frequently citing owner negligence as a reason for denial. This occurs despite the fact that engine sludge buildup is ine

The Sunroof wind deflector , the panel has become detached. It is loose and flapping when sunroof is open. Yes it is available for inspection. My safety was at risk because when it happened at first it scared me and I didn't know what happened. 2nd if it had came all the way off it could have flown into someone else's windshield and causing them to crash or swerve to miss it flying in the air. I did mention it to the dealership when it was there, but rather they looked at it or not I have no idea. No one else has inspected it. No warning lamps or other signals appeared before hand.
