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.

- Bristow, VA, USA

Car lost power and went into limp mode, it was pretty dangerous. The car is burning a large amount of oil and is making the spark plugs dirty. I have brought the car for about 6 oil consumption tests and Hyundai does nothing to fix it. Engine oil light has come on twice, and even the dealership said that it should not be burning so much oil.

Engine developed spontaneous loud knock and check engine light illuminated while driving at approximately 60mph. Could not continue driving and had to pull over on the side of a busy highway. Had to walk down the side of the busy highway to a safe area. Had vehicle towed to an independent repair shop, vehicle diagnosed with catastrophic engine failure due to failure of internal engine components. Repair shop stated this was a known problem with this particular vehicle and engine and manufacturer should be financially responsible for repairs.

Oil light began to turn on when making turns or braking. Took vehicle to location of last oil change, despite only being 2600 miles after the previous oil change and was informed "there was no oil" despite no evidence of any leak. At that rate, I'd be burning a quart of oil every 500 miles. I see there are recalls for this issue on multiple Hyundais including the Sonata, but different years than my 2016 Sonata Sport, and it includes the possibility of an engine fire.

- Arlington, TX, USA

I accelerated my vehicle onto the busy highway after waiting at the stop sign for passing traffic to clear enough. Getting up to efficient speed for the highway, at ~3000rpms, the oil and engine warning lamps flashed and the car jerked while the rpms abruptly dropped below 1500, slowing the car down. Assuming that a sensor initiated -??limp mode-?? I carefully drove ~100ft with the emergency flashers on to get to a safe place to pull over, preventing the possibility of an accident on the busy highway. I popped the hood, there was an odor similar to something being burned. Temperature gauge did not indicate engine running hot. Checked the oil- it was almost empty. This vehicle was last serviced with ~70,000 miles in May at Hyundai-??s service department at the dealership.

- Dadeville, AL, USA

The engine fails before 100,000 miles. Got an error code of P1326 (Wiring inspection/installation and engine replacement and error code P2600. The car suddenly dropped in MPH. Car is sluggish to accelerate and very difficult to go up hill. Little to no power on acceleration. Problem was identified at an independent service center, after inspection, taken to local dealer. Flashing check engine light came on once issue occurred. The engines in the Hyundai Sonatas are poor at best. Multiple people have needed their engines replaced in a very short time.

Lots of noise and car started smoking and stopped working while I was on the highway

- Mckinney, TX, USA

engine is the component with the issue. The car is at the dealership and has been for the past almost 6 weeks. car started "stuttering" or "stalling" while my son and I were in the car. My son has special needs. Luckily, it happened on our street and I was able to get back to my home. dealership has identified the problem: The car was 3 quarts low on oil and the oil had been leaking into the spark plugs. The car only has around 32500 miles on it. Hyundai has requested an oil consumption test. This requires me to drive it 1000 miles and have oil checked. They want me to do this 3 times! I will not feel safe doing that, knowing that oil is leaking into the spark plug assembly. I transport my special needs son and another young man who is severely autistic. I cannot take the chance of the car stalling while out driving possibly causing an accident. I barely put 50 miles on my car during a week. It will take me forever to do the oil consumption test. They know oil is leaking into the spark plugs. car started having issues (while in reverse) a week before the check engine light came on. No other warning lamps or messages appeared. Blue Link was contacted. They said the error code indicated a Powertrain problem. I had to have the car towed.

The intake manifold control runner motor has had to be replaced in my car multiple times. Twice from may 2021 to July 2021. The check engine light would come on and would reduce car performance drastically. Code scanner gave the p200a performance bank 1.

From April of 2020 to July of 2021. I have had 3 sets of 3 oil consumption tests for my car at 3 different Hyundai dealerships. I have spent $400-500 dollars on oil changes, oil filter cleaning, and fixing an oil peg that was broke. Which was not brought to my attention right away even though I was going to dealer ships almost every month this year. I just finished the final oil consumption test here in Conroe, Texas. Even though from the latest oil consumption tests, I have burnt.50-1 full quart of oil. They still have denied me an engine replacement. My oil changes does not last 5k miles but barely 1k. The oil is always black, it never is honey gold for long. Because Hyundai is not giving me a new engine to resolve this issue despite all these tests and there being a lawsuit on this make /model. I now have to pay for an oil change every month rather than the average of 2 times a year. I do feel treated unfairly and not heard by Hyundai. It does not feel right to not have this fixed. I understand it is out of warranty. Can I please open an investigation on this matter ? Thank you

I received Hyundai's Recall notice for Recall Campaign 198 regarding premature connecting rod bearings. I scheduled a service appointment at First Hyundai at 270 E Washington St, North Attleborough, MA 02760. (508) 699-4700 for April 29th, 2021. My car's engine started making noises on April 24th, 2021. I stopped the vehicle and had it towed to First Hyundai (listed above). The dealership took more than 7 days to inspect the vehicle and diagnosed it as connecting rod failure requiring a new engine. I contacted Hyundai customer service to arrange for "alternate transportation". Hyundai assigned me a case manager on 5/18/2021, but despite multiple phone calls and messages, I was not able to actually speak to my case manager until 5/25/2021. Hyundai refused to authorize alternate transportation prior to this, and when I spoke to my case manager she would only authorize reimbursements up to $30 per day for a Hyundai rental vehicle and $20 per day for a non-Hyundai vehicle. I have been unable to secure alternate transportation from Hyundai, as there are no rental vehicles available at the prices Hyundai is willing to reimburse me for. It has now been more than 60 days, and my dealer has notified me that there will be further delays, even though they have received all of the necessary parts to repair my vehicle. I have kept extensive notes of the more than 25 phone calls I have made to both Hyundai and the First Hyundai dealership regarding this issue. At this point, I need assistance forcing Hyundai to honor the recall agreement they made.

The 2016 MY Sonata has been driven all across the state due to business. During a recent trip of a couple hundred miles, upon returning home, the vehicle shuddered and failed the next day. The vehicle was towed to the nearest Hyundai dealer, and was to be diagnosed. It took longer than expected, and upon calling back to determine the issue, they said the "engine was gone." They reached out to Hyundai corporate and were told the same thing. There were no other signs or symptoms, and the vehicle operated normally during the long trip home.

The engine begins to shake and makes a dieseling sound, the check engine light comes on, and we lose power to car. As we remove our foot from the gas, the light goes out and the engine stops. Sometimes it comes back on again and we have to pull to the side of the road and turn the car off. After that the check engine light goes away. When the light comes on, power to the engine is immediately cut and reduces as you press the accelerator pedal.

Yes I was driving on the expressway I saw smoke coming from my vents. I made it to the nearest neighborhood by my home stopped for it to cool down for 10 minutes I start my car back up & it was perfectly fine by time I made it to a stop sign it caught on fire while I was in the car. The fire department told me it was due to an electric/engine problem & nothing was my fault. I don't have insurance to cover it. The next morning I found out on the internet that all Hyundai's and Kia have a re call on cars due to engine fire risk. I was really devastated when I found out that my car has been on re call not once or twice but three times. By law, iam authorize to get a car or a check of how much the car is worth. I talked to Hyundai motor America headquarters Mrs. Gretchen told me that they notify me at the address that the car was registered in & not my current address and also she stated it's my fault. Which I don't understand how when nobody called text or email me personally just to see if I made it to my re call appointment in January. Not only I had another one in March I didn't know about as well then they have another re call I just found out about in June Hyundai better and has to do something now I could of lost my life & I lost everything I had my phone fedex equipment important paperwork etc. Fyi insurance has nothing to do with a re call car. By law I suppose to get something for that

I went to start my car on May 3, 2021 to go home and my car was sputtering and the check engine light was on. The dealership can't get to my car for 2 weeks. My car burns oil and doesn't make it from oil changes. I have had my spark plugs replaced when it did this the last time.

In Oct..2020 my Sonata was at pep-boys auto for a synthetic-oil change. Pep-boys called me to advise can't service the car for the oil change. Since last oil change 6K miles ago their was no oil in the engine. They saw this several times in the last year with 2.0 engine, they want no responsibility and said take your car to the dealer & open case the engine has a serious flaw, it burns the oil with the gasoline. They said a recall" documents attached. I went totexan Hyundai, put my car through a series of tests every 1000 miles. I was told the engine can be replaced you in the 10 yrs, however you over the 100K miles, will not B covered, a Hyundai motors would cover 50%. was told engines last 250-300K miles. I spent over 2K for ext. Warranty. It ran out at 100K. Hyundai has not backed up their car. Sonata hybrid was sold to me being dependable & lasting years. It failed terribly, I maintained my car always and now need NHTSA please help. On Hyundai forums many2.0 have same situation with oil disappearing. I prepaid on credit card $3531, texan Hyundai placed order for a new engine. Back ordered. Date to fix will be in during the month of july2021. All miles R highway to and from, katy to brenham college has no hills all straight run since day bought. These engines should last, there is a failure in design? not dependable car. Very defective 2.0 engine. Last 2 yr's I would smell burning oil in my car, I would open the window since no lights on dash. No oil in the engine, no dash light" pep-boys said those lights never were lit on the defective cars. If light would have taken to the dealer for service. My records which show this car was properly maintained. Hyundai should fix 2.0 engines, folks like me are in a hard situation. Thank you for hearing my situation.
