Exterior lighting, turn signalSep 24, 2021
Hyundai Motor America (Hyundai) is recalling certain 2015-2017 Sonata, 2016-2017 Sonata Hybrid, and Sonata Plug-In Hybrid vehicles. The Smart Junction Box (SJB) software logic may not properly interpret the signals received from the multifunction switch, which could cause the turn signal to activate in the opposite direction of what the driver intended.
A turn signal that activates in the opposite direction of what was intended by the driver increases the risk of a crash.
Dealers will update the SJB software, free of charge. Owner notification letters were mailed November 19, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 210.

Electrical system, instrument cluster/panelOct 20, 2015
Hyundai Motor America (Hyundai) is recalling certain model year 2015-2016 Sonata vehicles manufactured May 28, 2014, to August 21, 2015. The affected vehicles are equipped with an Antilock Braking System (ABS) warning light intended to warn the driver if there is an ABS malfunction. In the event of an ABS malfunction, the Brake System warning light will illuminate, but the ABS warning light will not illuminate.

Hyundai Motor America (Hyundai) is recalling certain 1.6 liter model year 2015 Sonata vehicles manufactured August 29, 2014, to October 28, 2014. The affected vehicles may have been assembled with an incorrect left axle shaft which may result in the shaft separating from the transaxle differential.
If the left axle shaft separates from the transaxle, the vehicle may stop moving, increasing the risk of a crash. Additionally, a separated axle shaft may allow the vehicle to roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Hyundai will notify owners, dealers will inspect and replace the axle shaft, as necessary, free of charge. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 126.

I have a used 2015 Hyundai Sonata that I purchased from a Hyundai dealership in December 2021 (due to the chip shortage, I had to purchase used). A few months later In June 2022 I was driving on the freeway and my car felt like it was losing acceleration. I was already planning to exit the next exit to go to my destination and as I was exiting and came to stop at the red light before I could then turn right .. my car started to violently shake. Ultimately, after going to my own car place the following day and them determining that the fuel injectors and the computer were not talking, I had it towed to Hyundai where after another 4 days they also determined it was that problem and they replaced the computer under warranty. Well today I was again on the toll road / freeway and I was in the fast lane, I suddenly felt a strong jolt and my malfunction light came on and it was blinking on the dash, I knew not to drive it based on the light and as I steered to the right shoulder to slow / stop and call AAA I could feel my car just lightly shaking again. My car is now at the same Hyundai dealership where I purchased it and I’m waiting for diagnostics on the problem. Before this all happened, the first time in 2022 I was having sporadic issues with pressing the start button and there was a bit of a delayed start at times, even after the computer was replaced I’ve still had hiccups with the start button at times but it’s been very sporadic and it has never been a starter issue (had my car place already check that). So I’m now waiting to hear if the computer indeed failed for a second time. They cannot assess my car until Monday or Tuesday at the dealership (today was a Friday, my car was towed there at about 11am today). If the computer did fail again, it lasted about 14,000 miles before it just died again. Quite frustrated at the moment. I already contacted Hyundai corporate and opened a second case today regarding all of this.

In September 2022, we noticed a noise coming from under the car hood. Sounded like a thump as we accelerated. We took it to the Hyundai’s service department and was told that they couldn’t hear anything or find a problem. They changed my oil. We continued to hear a noise but thought it wasn’t a concern. In February, a fairly new tire went flat and we returned to the Hyundai service department. I received a call later and was told that they could hear a noise and they checked, and my oil was extremely low. They topped it off and told me to return in a thousand miles to see if it was still burning oil. If it was burning significant oil at that point, they would seal it and begin the Hyundai oil consumption test. At about 600 miles, I could smell a strong plastic burning odor and we checked the dip stick and the oil was barely detectable. We called Hyundai and was told there was nothing they could do and we have to go the full thousand miles to determine if we qualify for the test. We are concerned are engine is going to stall, burn up or catch fire in our garage. They told us, we couldn’t get are car in to be looked at until the end of March. After doing some research, I am aware that there is a current class action lawsuit against Hyundai for this issue.

I have been keeping up with regular repairs and oil changes on my vehicle; so I was surprised when the oil light flashed once or twice in the past week, specifically when I took a turn tightly. The oil was low when I checked it so I added a quart and didn't think much of it except "I should get into a shop soon and have that checked out." Two days later, my RPMs red-lined past 6-7k and the car was revving up but was not accelerating at all. I pulled over and checked the engine again and without showing any kind of leaks (no spots in my driveway/parkingspot) the engine had consumed the oil I added and then some. Moreover, the problem with the engine revving up but not accelerating was not fixed when I added the oil. It could have been very dangerous if I were on the highway and was not able to accelerate for any reason that could put myself or my family at risk. Now, the car CAN reach speeds of 75+ miles per hour on the highway, but only after a LONG period of acceleration and seems to be burning oil VERY regularly. I've grown very concerned about catastrophic engine failure on the highway.

My car goes through 5 qts of oil every 1500 miles. I have been in contact with numerous dealerships in the area, and nobody will look at it until the engine fails. Was told thats the only engine recall they will honor. So I am basically being forced to drive an unsafe car. I have a case with Hyundai, and all they have told me is to continue working with service managers at dealerships, even though this is impossible. My car only has 97k on it, I have kept up on its oil changes (not that it matters) and now am forced to spend extra money just to keep it hopefully running. My case# with Hyundai is 20870570. I owe around $15k on this damn car, and the trade in value has come WAY down to around $6000. In no way can I afford to take on $9k of negative equity. How can the EPA force VW to buy back cars, when all they did was produce "bad" emissions, but Hyundai cant be forced to buy back vehicles that catch fire, get stolen on the regular, and break down in the middle of traffic endangering the lives of its occupants and others. This makes absolutely 0 sense.

My 2015 Hyundai Sonata Sport 2.4L is burning through oil like crazy and has been for a while now and I had no Idea. I get oil changes like I am suppose to do per the sticker and miles. Recently I drove about 4 hours away from home and I smelled burning but I had just got my breaks done and a oil change so I assumed it was the breaks . I got back home and still smelled the smell took it to the shop and they told me it was bone dry with NO oil at all. I was not at my mileage from the sticker so it wasn't time for me to get another oil change. They then told me these cars burns oil like crazy but that was the fist time anyone told me this and I have never had this issue ( I've had the car since Jan 2020 with no issues) They put more oil in it and told me to come back when it reaches the mileage. I went back to get my oil change and once again it was BARE!!!!!! They did the oil change and 2 weeks later I started my car and white smoke came from the engine part under the hood through my exhaust pipe AND my VENTS!! It was so much smoke I was afraid a fire was going to start!!! I lost a day at work and my daughter missed a day at school. Turns out I have a oil leak and I need my Valve seal cover gasket replaced. Not once did my oil light come on and TWICE my car had been completely out of oil! I am going to get my engine checked because who knows if it has done any damage (hopefully none). My car has never overheated or my check engine light has never came on. I see there a recall for this exact situation but the years covered was from 2008 or something until 2014 and I have a 2015! This is clearly a ongoing problem with Hyundai and something needs to be done. This is not a sweep under the rug issue. Its literally ruining peoples cars and we are left to fend for ourselves. Something or someone needs to advocate for the customer because the company clearly is not listening to complaints.

After taking my car in multiple times to be serviced for a "Hybrid System Warning" mid last year, they were unable to read any error codes or diagnose any issue. I took it to two separate dealerships with no luck fixing the issue. I then completely broke down due to the same "Hybrid System Warning" on the highway on 7/26/22 heading to Pigeon Forge, TN with two children in the car. I had to have my car towed to the closest Hyundai dealership in Knoxville. They were unable to diagnose and fix my car within the timeframe I was in town. Since Hyundai would not provide me with a loaner, I had to get a rental car to get home that I was not reimbursed for. We ended up paying out of pocket to replace the safety plug/fuse and the power relay assembly on 8/9/22. After having the car back for three months, the warning popped up again on 10/18/22 just as it did earlier that same year. I immediately called to schedule a service appointment with Hyundai and had to wait almost four months to get a service appointment here in Cincinnati. The appointment was on 1/26/23 and they have yet to "replicate the issue" so they are unable to diagnose the car. I am supposed to pick up the car this week even though it's a safety hazard. I have had two cases open with Hyundai Customer Affairs but since they cannot diagnose the car, there is nothing they can do. They have been absolutely no help at all.

Engine seized with no warning. When speaking to a mechanic & the tow truck driver they both pointed out this is a known problem with the car. My teenage daughter was behind the wheel when this happened. There is such a demand for these engines the car has been in the dealership for 6 weeks now & I was informed that it is back ordered from Korea with no date of delivery. I am now stranded with no transportation & engine is under warranty. Car is at Elgin Hyundai, Illinois. If they are unable to get car running for unknown time & know this is a well known problem I feel a recall should be done on this car

I was driving on the freeway and all the sudden the check engine light started flashing. At the same time the engine slowed down and would not accelerate past 60 mph. I took the first freeway exit and drove to the nearest auto parts store. The store clerk hooked up a code reader and it came back with a P1326 code, Power Train System. Is it a real problem or just another bad sensor?

On January 6, 2023, I was driving on the interstate when suddenly the engine started vibrating, the check engine light came on, and I lost engine power. As I was in the left lane of a multilane interstate, I had to negotiate getting over to the right emergency lane. Because of the loss of power, I felt like this put me in a dangerous situation. Anyway, once I got pulled over, I had the vehicle towed to a Hyundai dealership. After diagnosing the vehicle, they say the vehicle needs a new engine. The vehicle had been consuming excessive oil since I purchased the vehicle in 2018 and has been getting progressively worse. At the time of the engine failure, it was burning about 1 quart of oil every 1000 miles. The dealership tried getting HMA to cover the engine replacement cost even though the vehicle was out of warranty but was denied. I've uploaded a picture of the technician's diagnosis and HMA's response to request for engine replacement coverage.

My car has 113,000 miles and the engine went out going down the highway with my young daughter in the car. This could have been a disaster if someone would have been behind us. After researching about my issues I found almost all their motors are going out or catching fire. Someone needs to hold them accountable. My car has been in the shop for weeks now with no approval from Hyundai. My daughter almost died last year in a car wreck. What if someone’s engine goes out with someone behind them. Someone could lose a life. This is serious.
