The engine light has come on and I have done extensive repairs on my vehicle since January 2022. No warning signs showed prior as I have kept up with maintenance on the car since the 60,000 mile marker. The valve gasket cover was replaced as the engine was smoking due to an oil leak. A pipe was repaired due to the leak. The engine camshaft position sensor was replaced. There is still issues with the engine after replacing the CVVT cover and plugs. The spark plugs have been replaced. If my car stalls or blows on the highway, this can cause a major accident putting myself and others at risk. I have done multiple tests with Hyundai dealerships and Firestone and AutoZone and no one can tell me what the ultimate issue is with the Sonata.

Car shut off on me twice as i driving. Once along time ago but again just October 18th while I was driving on the highway I know hyndai has a class action lawsuit against them but the fact it shut off on me twice and the first time the issue accrued I took it to Fairfax Hyundai and they weren-??t phased at all and didn-??t even bother to check/diagnose my car because I didn-??t have a check engine light illumination at the time of incident ;because they were backed up with cars but a huge safety concern, and they just simply let me leave the shop and didn-??t advise me to be safe/careful. I want to bring this to your attention because I have no voice and if anything could be taken from this is that I could-??ve crashed and caused an accident the first time this ever happened because I was in the city bumper to bumper when it shut off on me and it-??s would-??ve been my fault and my issues to deal with. Also this car is very unreliable i don-??t know what star rating you guys have gave this car but it needs to be a -0. I got it when it was at 89,000 from a private dealer but the car just went downhill since I got it then I have been nothing but Patient with the car along with keeping up with maintenance & recalls, but after 4-5 months I-??ve already changed the transmission out of pocket @ around 100k miles, cv axle later on along with, right side whole knee suspension, engine packs and spark plugs TWICE, front break calipers, and now they-??re changing the engine block warranted out through Hyundai after the car stalled out on me again the second time on oct 18th with an check engine light where the car is now getting warranty worked. I just hope you advocate and push demand on hyndai that they-??re screwing consumers like me that have to deal with the pain & agony we have to go through these dealerships who try to charge us an arm and a leg.please do something about this dangerous situation and hold them accountable especially the private dealerships associated with hyndai please.

My vehicle lost power exiting the freeway. I went from 70 miles an hour to 10 miles per hour in a matter of seconds. The Check Hybrid system, Turn off engine HEV ! triangle showed up on the dash, then the car slowed to a halt. I had to get my vehicle towed home, then towed to the dealer the next day. The problem with this is, for the past year, the Check Hybrid System HEV light would come on. I took it to the World Car Hyundai North dealership in Live Oak, Texas and a few months later, it's doing the same thing. My vehicle was in the shop at World Car Hyundai from March 24, 2022 until 9/9/2022. I drove my vehicle one week, went out of the country for 2 weeks and upon return, coming from the airport almost home, the car does the same thing. You would think after having my vehicle for 6 months, the problem would be fixed. I started bringing my car in for this problem September of 2021. I was told, I needed an oil change, a new battery, ne plugs, codes checked, etc. None of this seemed to fix my vehicle, because a few weeks later, the car would slow to an almost stop and I would have it towed to the dealership again. There has been several mechanics working on my vehicle and they've all said something differently. My vehicle was never written up for the correct problem until recently, when the manager was able to drive my vehicle and it stopped on him. I don't feel safe driving this vehicle anymore. I have taken this car to the dealer ship for the same problem, actually once in 2018 and every other month since 2021. I've been inconvenienced, , put on hold, far to long, I need a new vehicle and I need a loaner car, while my they're trying to figure out what to do. I've been told I needed a new engine twice, but all of a sudden, it passes the engine test and there is something else that the dealership is trying to do to fix the problem. Well, since I've been taking my car back and forth to the dealership, it is now out of warranty. The car remains unsafe to drive.

Oil Consumption Test Failed, I was originally told if I could prove it was burning oil and not leaking then I would receive a new engine. New engine rejected saying Hyundai no longer warranty engines for that reason. Was told that when motor seized to have it reevaluated for bearing or rod failure. No way to determine bearing or rod was cause of oil consumption without tearing the motor apart. Knocking noise from engine and experienced Engine Failure, resulted in being stranded in middle of highway with my kids 1 yr after oil consumption test. Hyundai rejecting engine replacement due to low compression from cylinders. Not willing to honor their warranty after an obvious lemon of a motor.

I assuming it-??s my knock sensor and hopefully the harness or anything doesn-??t have to be replaced but my car went go pass 60mph and when I first get up to 16-20mph it jerks then gains a bit of power and also my check engine light came

On Tuesday February 1st 2022, I was driving home from work on the interstate doing 70mph when my engine shut off. There was no warning lights...nothing. By the grace of God I was able to pull over on the right shoulder without getting in an accident. That was TOTALLY unacceptable! Scared me to death! Come to find out the the engine blew! I babied this car which only had 104,000 miles. Hyundai knows about this problem and have done nothing to help compensate the owners of these. I have five kids and it is going to cost me 6,000 dollars for another engine. That cost includes labor as well. If you ever wanted to fight for the little guy, now is the time! Thank you in advance!

Oil light came on when vehicle was almost out of oil. Engine could have seized Dealer says it is out of warranty because I am 2nd owner. 100,000 power train warrenty defaults to 60,000 for 2nd owner. Problem occurred just under 70,000. Warning oil light came on for the first time ever at 69,000 miles. Came on again after getting an oil change at 3,000 miles. Took 3 quarts to fill back to full. Engine now burns oil and must be refilled with nearly 2 quarts every 1000 miles.

Car unexpectedly stopped working and became disabled while trveling 40 - 50 mph on the freeway. Complete loss of power. Danger of a collision on the freeway. All dash lights and warning lights came on. Car would not shift and would not accelerate. It was unsafe to drive and could hardly move off the road. The first year I had the car the engine light came on and loss of power. I took it to the dealership immediately. Whenever I took the car to the dealer they said there were no codes and the car was was fine. The entire time I owned the car I would lose power on inclined roads and engine light would come on and off. Last week November 18 the car stalled and could not drive uphill again risk of a collision from the rear. I took the car to the dealer they said the car was fine. The dealership has never tried to fix the problem and claimed they could not duplicate the problem. Today 12/1/2021 the car stopped operating on the freeway completely and I had to tow it to the dealership. This car has been a safety hazard within the first year and Hyundai has done anything to address the problem.

The engine keeps stalling and the engine light is flashing. The engine burns oil every 1,000 miles and the oil light will illuminate and go away. The dealership has said they fixed the issue but the issue keeps arising with no resolution. This issues is known for all Hyundai's and they are not doing anything about it. My car has stalled out on highways and I don't feel comfortable driving it out of the state.

While driving car loses power, foot is on the gas car will not move. Then jerks. Car is in reverse and it still moves forward

At about 75,000 miles my 2016 Sonata limited 2.4L started needing oil added between regular oil changes (all mileage and maintenance by one driver). The vehicle is now 85,000 miles and I am adding 2 qts. There are no leaks from the engine so it must be burning through the exhaust, which can't be good for the emissions system and any future smog check - or the environment. The dashboard warning lights do not come on when the oil is low. This could result in catastrophic engine failure. The vehicle also experiences engine knocking and hesitating when accelerating from 30mph. This has been a safety issue when merging onto the highway, which is almost all of my driving.

- Brentwood, CA, USA

Car engine will rev up at low speeds (30 miles and under) and get stuck. I have to press the brake and hold it down, put the car in park and hit gas pedal to get it to go into lower gear. Has happened several times. I have told the Hyundai service dept about it a few times but they cannot repair it because they cannot simulate it happening. First happened approx. 2 years ago; did not happen again for several months. But now it is happening more often. 4 times in the last month. Most recent time was 1/11/21.

Car runs out of oil well before 2000 miles/2 months. When accelerating the car is sluggish the engine is ticking and feels like the engine is going to seize, no matter if the car is moving 5mph or 70 mph.

- Bolingbrook, IL, USA

When accelerating there is a ticking noise coming from engine. This has been happening for a while after I got the update and new wiring harness from the campaign. I'm scared to drive my car, I accelerate slowly because I get nervous it will blow up. I took this car to a Hyundai dealership and they quoted me over 500 dollars for this repair and it might not even fix it.

- Bolingbrook, IL, USA

Car stopped going into reverse, was told that it needed a new clutch actuator, but new actuator would not work in car so they reprogrammed it and put old one back in car, 500 miles later car is doing same thing again with not working in reverse!

- Tompkinsville, KY, USA

Engine is using 3 quarts of oil per 2,000 miles and transmission keeps have shifting problems that they just keep reprogramming it to fix, engine stalls.

- Tompkinsville, KY, USA

After a period of driving, which is random at best, the check engine light will appear and the vehicle will start to shudder and lose its ability to accelerate. This happens when the vehicle is in motion and happens both on the freeway at high speeds, as well as on city streets in low speeds. The only way to get this to stop is try and get to a safe space of the road and turn off the vehicle. It is very scary and dangerous especially in southern California freeway traffic and in mountain passes as you lose the ability to maintain speed in the middle of traffic. This could very easily cause an accident. This has happened to me on 7 different occasions over the past 2 months at random times.

- Bakersfield, CA, USA
