1st Incident: The engine lost its acceleration power on the highway, giving a rattling noise. It was identified as misfire in cylinder 3. This was repaired and gaskets and timing chain replaced. 2nd Incident: The engine lost acceleration again on the highway with a loud rattling noise. On checking the OBD scanner it showed the Knock Sensor as the problem. On taking it into the dealership a KSDS software update was done. Current Situation: The car drinks up 2-3 qt of oil for every 1000 miles and has an intermittent rattling noise when accelerating Losing engine acceleration power on the middle of the highway is a very serious issue. And this keeps happening multiple times and Hyundai has refused to give me a proper explanation on this issue. Other mechanics have suggested to get a replacement from Hyundai as there is already a Lawsuit against these Faulty engines. On contacting Hyundai there has been no proper response. Please look into this as losing power on a busy highway poses danger not only to our car but to other oncoming vehicles as well. It has been a very harrowing experience for us and I am left with no option but to drive a faulty car which might lose power at anytime.

Engine light appeared on my dashboard in late Feb 2024. At the same time, there was a noted fluid leak on my parking skirt so I immediately stopped driving it. On [xxx] I had car towed to mike's automative service station in South milwaukee, Wisconsin. He remedied the engine issue with 'leak stop'. on [xxx], I was traveling an [xxx] from milwaukee to oshkosh. Around half way, the engine light began flashing, the oil light was on and the car lost ability to accelerate. I engaged my hazard lights given I was in high traffic at that time and 'limped' car to the nearst gas station, to avoid being stranded on the highway. It was towed to a nearby location, richfield service center-richfield wi. Both the tow truck driver and the service station rep, sean, advised this oil-leaking engine business was a widespread and well-known manufacturer defect for this vehicle's make/model/year. They performed a brief diagnostic review and advised the engine would need full replacement to continue driving. I reported this incident to Hyundai's customer service online portal this day, too and have requested they replace the engine, given the mileage has not even reached 77,000 miles. I found no active recall or warranty on this vehicle but can prove I am the second owner, having inherited it from the original purchaser, the late [xxx] in 2016/2017 (unsure exact date). The vehicle is available for inspection at this time. I felt traumatized by this event, praying not to be run over on the highway while the car moved at a snail's pace and feeling terribly unsafe in pushing the car to the closest gas station. I felt everyone around me was in danger of not seeing me in time to stop or avoid collision with me. No official inspection has been completed by manufacturer, police, insurance or anyone besides the mechanics at the richfield service center locatio in richfield Wisconsin, on [xxx]. more detail not afforded in text space here.

The blind spot detection system needs alignment. When the blind spot detection fails it disables traction control and anti-lock brakes. The parking sensor and backup sensors should have nothing to do with the antilogue brakes or traction control. Since these items are disabled traction does not exist and anti-lock brakes are ineffective.

The wind guard for the panoramic sunroof of my 2016 Hyundai Sonata Hybrid broke & flew almost all the way off while driving down [XXX] in the Cleveland area. I was able to grab the end before it broke off completely and flew into traffic behind me. There was no warning prior to detachment. Hyundai insists this part failure is not part of a prior recall for this exact same product failure on this make & model and therefore will not cover. Their suggested solution is glue.

found me driving on I 75 and I put the Cruise Control at 70 miles, instead of maintaining the speed at 70miles the vehicle accelerated to more than 90 miles per hour I had to quickly put my foot on the brake otherwise I could have an accident with the vehicle from the front, after all this happened, I felt the car was losing speed, I tried to accelerate but it did not go over 60 miles per hour. I took it to the mechanic and they did not detect anything in the vehicle's computer. This vehicle also turns off at times when you are driving and it turns off it also spend too much oil motor, I started looking for information on this model of car and I see that there are more than 550 people who have the same problem as me, this is an unsafe vehicle for the road

My husband (Scott) was driving the car on Florida highway 408 eastbound approaching the exit 21 on 10/12/2023 around 8 am. Scott heard something pop suddenly and saw fire shooting out from both sides of the car in the rearview mirrors. Upon noticing the fire, he tried to slow down to pull over the car, but brakes failed (went to the floor). A police officer on the road happened to see the fire so he drove next to my husband's car and Scott yelled at officer that he had no brakes. The officer went ahead of Scott to help Scott's car slow down. When approaching uphill slopes by the exit, Scott was finally able to use the emergency brakes to come to a complete stop. The fire engine came right away and put out the fire which took over 20 minutes. My husband is handicapped and him walking away from such car catastrophic fire unharmed was near miracle. Two weeks before the fire, I happened to take the car in for checkup at Greenway Hyundai Orlando and the 2.5 hour inspection found nothing wrong with my car. I wanted my car checked because my car stalled briefly pulling out of a parking space a few days earlier.

On 10/06/23, I went to the Meriden Hyundai Dealership to get my transmission and brakes serviced. During the multi-point inspection, the technician noticed that the oil pan had a hair line crack at the drain plug site. I found that peculiar especially since my oil changes have been performed at the same place for the past 5 years. My last oil change was performed on 09/09/23. The technicians never mention any problems. I did not notice any oil leaking. The oil was actually being trapped in the undershield. I have contacted that company and they have conducted an investigation. They do not find any fault with their workmanship. However, something is wrong. I see there are other Hyundai vehicles having trouble with their oil pan and drain plugs.

My vehicle is experiencing high oil consumption. An oil light came on for about a second and went out. When I returned home, I checked the oil, and it was empty. We have our oil changed at our dealership everyou 3000-3500 miles. The next time frame, I checked the oil regularly and noticed it was getting low very quickly. When we returned to the dealership we were put on a 1000 mile oil consumption test, then the next time had a combustion chamber cleanse, and then returned at another 1000 miles and the dealership disputed the amount of used oil, and told us if there were additional issues we would need to start over. It continues to burn unusually high, but we are monitoring it. Hyundai says their threshold is a quart every 1000 miles.

My car is burning oil at an excessive rate. I bought this car August 2022 and within the first year I was having to constantly fill up my car with oil to make it through the month. I finally had a claim open for the oil test and at first was told that I do qualify for a new engine and to bring it in for pictures etc to get this going. This was around December 2022/January 2023I bring my car in to Hyundai dealership. they did not do this and I was told that everything should be okay no engine replacement.Again I had to put oil in before my next oil change. I brought it in on April 3 2023 by April 27th my car had consumed over 3L of oil. Another claim was filed and Hyundai denied stating car out of warranty. The dealership denies there-??s any issues or lawsuit associated with my make/model/year for my car. A quick google search has shown that there is indeed. One article states that a recall was going to announced for May 19th2023 for this same issue.

Panoramic sunroof wind deflector bonding failed. The detached wind deflector can come off while driving and interferes with the sunroof closing. It-??s possible that the wind deflector and the glass sunroof could detach entirely while driving and cause an accident. I have used the sunroof feature less than 5 times since purchasing the vehicle in May 2019. There is a recall on this part for the Sonata Hybrids for the dates of 12/8/14 to 8/18/15. On 4/7/23 Long Hyundai of Chattanooga confirmed the problem and charged me $185.73 to look at the problem. They will order a new part and install it which will cost me $398.94. I declined because I think that this is a manufactured flaw that should be repaired by Hyundai at no cost to me. I have spoken at length with Hyundai customer service representatives and was informed that they would not repair it because it is not included in the recall. They recommended that I contact Better Business Bureau. BBB Auto Line informed me that NHTSA handles recall issues.
