2020 Hyundai Elantra complaints

The contact owns a 2020 Hyundai Elantra. The contact stated while driving at various speeds and releasing the accelerator pedal to come to a stop, the vehicle sputtered, made a clicking sound, and stalled. The check engine warning light was illuminated. The contact was able to pull over to the side of the road. The contact shifted to neutral(N) and was able to restart the vehicle. The contact stated that the failure had been recurring while driving. The vehicle was taken to an independent mechanic, where it was diagnosed with engine failure. The mechanic related the failure to NHTSA Campaign Number: 21V301000 (Engine) and referred the contact to the manufacturer for assistance. The dealer and the manufacturer were notified of the failure and informed the contact that the VIN was not included in the recall. The vehicle was not repaired. The failure mileage was approximately 70,000.

The soldering of the end cap in the engine fuel rail failed and allowed gas under pressure to leak out. Fuel sprayed out in the engine compartment and the smell was evident inside and outside of the vehicle while in operation. Not sure how it did not start an engine fire. Repairing was a simple task that I handled as this is the only vehicle available to me. Ordered a new fuel rail which was only available from a dealer without issue and completing the repair went without issue. Did not have anyone else look at the problem as once I figured out the problem, did not want to drive the car anywhere. I have the old fuel rail for anyone who needs to inspect it.

It makes noise when driving a mph

A fire started in the passenger headlight assembly. The car had only been running for about 7 minutes directly prior to the fire being noticed. At the time of the fire it was parked & turned off. No injuries. It burned thru/melted part of the bumper & damaged something with the windshield washer fluid. Several people were at risk due to there being a fire! The car was parked at a gas station when the fire broke out. I don't think they have done a thorough investigation yet. It is current at Hyundai of Metairie in Metairie LA. According to the service technician my car is not the only one they have there that had the same thing happen. No warning signs, sounds, or anything else.

Car is almost stalling Randomly on the highway . The rpm’s go up and car won’t speed up slows down . Stalls very randomly I am terrified to drive it , I used to have so much confidence on a newer Hyundai .

The car starting knocking while driving and later found out it’s due to a knock sensor issue, at first the check engine light didn’t come on, days later it’s been blinking on and off since then.

On [XXX} 2023, [XXX]. I was driving to work which is only 5 miles away. All my my dash lights came on. Next thing I know smoke, and fire started billowing out from under the hood. I started having a panic attack because the electrical system died and I could get out of the car. I then realized all I had to do was open the door handle. I called 911 and the police and fire department came and put the fire out. The entire under the hood was burned and some windows cracked from the heat. It was a scary ordeal. Im not sure what cause the engine to catch fire. I filed a report with the police and the car was towed. My insurance came and towed it to do an evaluation. They deemed it a total loss and blamed the engine. There was a recall on my engine for fires and state farm documented it in my loss report. I'm not sure who to go after for this because I had the car for 10 months, put $4000 down. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The component which failed was the engine. This engine has been burning oil from the day in which we bought it. This engine puts everyone at risk because it failed in the middle of traffic, and We could have been hit by oncoming traffic. The problem could not be reproduced because the engine tied up in the middle of the road. We had the vehicle towed to the dealer who said it was not covered under the warranty due to abuse. The oil had been changed at the proper intervals, and we are sure the engine failed because it was a poorly made engine. This engine had exactly 69,993 miles when it tied up. We attempted to have it repaired at 54 thousand miles but the dealer said we need more money to check it out, but when they sold it they said the engine was covered. When we brought it in we asked for a loaner, but initially they refused. Three weeks later, we demanded a loaner as we happen to see the owner Steve Taylor at the customer service desk and he complied. After a month and a half without our car getting repaired they said we did not change the oil at the proper intervals, and said we need receipts for every oil change. We have a fully equipped auto shop in our steel-frame barn in which we replace engines for our Cars-for-Christ fundraiser program, and completed all the oil changes through our own mechanic. Before we could retrieve our purchase our oil purchase receipts they said, Hyundai will not replace this motor and it is not covered, we can put another engine in your car

THIS VEHICLE RECENTLY HAD A NEW ENGINE AND NEW TRANSMISSION INSTALLED INTO IT IN FEBRUARY OF THIS YEAR. LESS THAN 10K MILES ON IT. THE ENGINE LIGHT CAME ON ON 4/12/2024 AND I TOOK IT BACK TO THE DEALER IMMEDIATELY. THEY CALLED ME ON 4/15/2024 STATING THAT THEIR ENGINEERS AND TECHS HAD HAD PROBLEMS ON THE TRANSMISSION RECENTLY INSTALLED ON IT DUE TO MANUFACTURING AND/OR FAULTY PARTS, AND TO REPLACE THAT TRANSMISSION WITH A NEW ONE. STILL WAITING TO GET THE VEHICLE BACK AT THIS POINT IN TIME.

The vehicles engine has gone through a gradual decrease of power and then the car went into "Limp mode" and began burning oil. I have taken it to dealer multiple times and they would run diagnostic and never find anything significant. When it went into limp mode I took it back to dealer and they ran diagnostic and said the engine was bad. They said that the car is out of warranty and they would not cover the repairs. When I look into the problems that the vehicle was exhibiting there was a recall 203 that describes my problem exactly. When I look it shows this was completed at around 6000 miles. I believe this was done to early in the vehicles life and it didn't exhibit any of these issues. Now at 80,000 miles the engine now has all the issues described in the recall and the manufacturer will not replace or repair the engine

I have a code "P0867 Transmission Fluid Pressure" that showed up on my car. Yes. Dealership refused to fix under "Service Campaign [XXX]". Dealership confirmed issue. No. There is a check engine light that appeared. To continue after the questions, Max Hyundai of Manhattan, address: 8020 US-24, Manhattan, KS 66502. Refused to fix my vehicle under "service campaign [XXX]". As the service campaign indicates Code P0867 must be present, which it is. As well as a VIN that starts with [XXX], which my vehicle also has. As well as 20MY Elantra's. Which my car falls into that category as well.

The forward collision or emergency braking system gets activated by direct sunlight. Almost every day I drive with the sun directly in front of me in the morning and the car can activate this system with no need when going 30 to 75 mph on the 405, an extremely busy highway. There have been many almost rear ends if I wasn't able to accelerate through the braking. This is a weekly if almost daily occurrence. The independent auto shop said it can happen but they have replaced break pads twice and I'm only at 60,000 miles.

Engine seized while going 55-60mph with warning lights only 15 seconds before my vehicle completely stopped on the highway [XXX] ) The engine was replaced by Hyundai along with the manifold and catalytic converter. Vehicle lost all control and power and started excessively knocking while I tried to get to the shoulder but only made it to the right lane. The safety of others and myself were out at risk due to no control of the vehicle. Repair order attached INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Good morning, I was hearing a rubbing noise every time I turned my steering wheel on my 3020 Hyundai Elantra. I did some research and found a Hyundai service bulletin explaining the worm gear shaft. I brought it to my local Hyundai dealership in Manchester New Hampshire. They confirmed that it was indeed the worm gear shaft. They replaced it and charged me but when I called the Hyundai corporate office, they explained to me they would not be able to reimburse me even though it has happened on many of their Hyundai and other cars. I am requesting help for this unfortunate situation. The cost of replacement was over $500. Why is the worm gear shaft problem not a recall as of yet? If I would not have had this fixed, it would have caused other problems in the steering. Ty

Transmission failed - car disabled at 85mph

Started noticing my 2020 Elantra was "jerking", "lurching" while in motion of driving. RPM would shoot up. A handful of times I would be losing power and almost not make to where I was headed. Starting/Turning from a dead stop, I would have no power and then suddenly it would surge and then I could get up to speed. I did not have any indication before hand or while driving. I did not have any lights come up, while driving or when it did the startup check when turned on. I barely made it to a Auto service, he drove it from one end of the parking lot to the other, then whipped into a bay for him to look at. I was told it was the Transmission, specifically CVT slippage and he suggested I do not drive home.

TOOK OUR VEHICLE TO THE LOCAL HYUNDAI DEALER ON 1/30/2024 TO HAVE THEM LOOK AT THE ENGINE AS MY REGULAR MECHANIC STATED THE "ENGINE WAS KNOCKING" AT THE MOST RECENT OIL CHANGE, AND GET IT TO THE DEALER AS IT SHOULD BE UNDER WARRANTY. TURNS OUT IT DID NEED AN ENGINE WHICH THEY REPLACED YESTERDAY FINALLY, HOWEVER WHEN THEY TOOK IT FOR A TEST DRIVE THEY STILL HEARD NOISES. THEY EXAMINED IT FURTHER AND TODAY THEY NOTIFIED ME IT ALSO NEEDED A NEW TRANSMISSION. THIS VEHICLE WE HAVE HAD SINCE WE BOUGHT IT NEW IN JANUARY OF 2021, HAD LESS THAN 10K MILES ON IT WHEN WE TOOK IT INTO THE DEALER ON 1/30/2024. THIS IS ABSOLUTELY UNACCEPTABLE. THANK GOODNESS I HAD ALL MY RECEIPTS TO PROVE REGULAR PROOF OF MAINTENANCE ESP SINCE I HAVE A REGULAR GUY AND DID NOT HAVE IT DONE AT THE DEALERS.

I took the vehicle in for it's regular oil change on 1/19/2024. My regular mechanic stated to me that "the engine is knocking, you need to get it to the dealer so they can fix the issue as it should be under warranty." He finished the oil change and we came home and immediately made an appointment with our local Hyundai Dealer - that appointment is on 1/30/2024 at 9 am. This is an extremely concerning issue as it affects the whole vehicle and the ability of it to be driven and last a long time. No warning lamps, or messages occurred for this issue, only the statement by my regular mechanic. I want to make sure this is documented in case Hyundai tries to get out of fixing the issue. This could be a very expensive problem. The appointment was made for the 30,000 mile service, but I will make sure they are aware of the engine issue when I take it in as well.

The contact owns a 2020 Hyundai Elantra. The contact stated that the vehicle failed to start without approximately 15-20 attempts. The vehicle had since failed to start completely. There were no warning lights illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the starter had failed causing the engine to seize. The contact was informed that the engine needed to be replaced. The vehicle was then towed to the dealer and the contact was informed that there were two open recalls on the vehicle. The vehicle received the recall repairs however, the starter was not replaced. The manufacturer was made aware of the failure and the two unrelated recalls were confirmed with the VIN. Additionally, it was also confirmed that the replacement of the engine was no longer covered under warranty. The approximate failure mileage was 87,000.

The engine at 41,000 miles had a catastrophic engine failure on December 22, 2023. It blew up with all maintenance done on time. I bought this car on February 28, 2023 and I heard the same knocking noise a week after the dealer kept my car for 36 days and was unable to re-create the problem. The car has now been in the shop for 15 days and I believe it is a complete lemon. I do not trust the safety of this vehicle and I see others are filing complaints ago Hyundai and Kia for the same thing I want to be reimbursed and my loan canceled.

My high beam lights have been replaced but still arent working

The contact owns a 2020 Hyundai Elantra. The contact stated that while driving at various speeds, the vehicle was sluggish and hesitant while accelerating. Additionally, the vehicle was consuming an excessive amount of engine oil. The check engine warning light was illuminated. The vehicle was taken to the dealer to be diagnosed.

My check engine light turns on and I’ve taken it to Hyundai to have it fixed and all they do is turn the light off and say it’s a sensor issue but it’s the fourth time the light has turned on I’m worried their is an issue with the pistons or the big e overheating. It’s also brutning a lot of oil that every 3-4K miles the oil drops to 75% full.

There has been a noise coming from my steering column. Its sounds a like rubbing or whirring noise. It only happens at low or stationary speeds. I took the vehicle to a local shop in my area. They diagnosed the problem as the Worm Shaft Assembly ( located inside the steering column). If steering fails while driving, it can a crash and lead to significant injury. While my steering has not failed or led to any accidents, its very possible and a real risk.

On Aug 30, 2023 I went to a Germain Hyundai for the usual maintenance of my Hyundai Elantra 2020 where they checked the condition of the belts and it passed. Fast forward Oct 1, 2023 the timing belt snapped and I had it serviced at Hyundai Great Lakes Dublin. I aired out my concern that it is too early for that belt to break since my mileage is only at approximately 25000, while their manual even says that the usual replacement /maintenance for the timing belt. So I urged them to check what caused it to break. Oct 15, 2023 I was driving off of freeway and we suddenly heard the belt snapped again and the car started to slow down on its own. It was a crazy experience as we were in the middle lane and we could no longer control the speed of the car. The Hyundai service center did not take this matter seriously and only recommended that the belts be replaced again. Essentially, I am in so much concern of my safety now given the situation that even the service center did not take time to figure out what is causing the belt to break and not being able to identify that puts me in a traumatic and unsafe situation of driving this vehicle , knowing it could break anytime.

I’ve had my car for about 5/6 months and it’s been broken into twice and was recently stolen. I haven’t been notified from Hyundai dealership about any recalls. Recently I called Ray Skillman where I purchased the car and a man said that there was a recall on my car a few days after I purchased the vehicle. I haven’t received any letters or notification about this from Hyundai and if they did it could’ve prevented me dealing with my car being broken into,damaged,and now stolen .

No difference between high and low beems

Hyundai updated my car with the “anti-thief” software a few months ago. It clearly did nothing because my car was still stolen. They need to install immobilizers for free to really try to fix the problem!

Transmission studders and looses acceleration while driving

NORMAL DRIVING, APPLIED BRAKES AND PEDAL VERY HARD TO PUSH DOWN AND STOP AND VERY FORTUNATE TO STOP AT ALL, NOW HAS HAPPENED TWICE. (WHAT TO DO?) SCARED TO DRIVE THE VEHICLE!

Leak without windshield

The contact's girlfriend owns a 2020 Hyundai Elantra. The contact stated that while his girlfriend was driving at an undisclosed speed, the transmission failed to downshift into 2nd gear.

Driving on a road trip, 2.5 hours in. All doors were locked. Drove over a road change from tunnel to bridge, small bump, and dashboard started beeping and flashing that a door opened. Driver side back door (where my child was sitting) opened, air was rushing in. We had to brake ( on a highway bridge to pull over) and unlock door to get it to close again. The door popped open while still locked. Called Hyundai and they said bring it in, but we probably didn't shut it. It was absolutely shut and locked.

When I start off I give my car gas but it does not want to speed up. The rpm drops to 2 and does not move as I push the gas to go to get out of the way of traffic behind me. It goes about 600 ft before it kicks in. Then it runs normal. It's still under manufacture warrenty (3 more years and 20000 more miles unde warrenty). I've taken it to the dealership and they didn't see anything. Said they would have to keep it a couple of days to check it out. It's my only means of transportation but the never have a loner car for me to use till I get mine back. I've seen others with same complaint so why is there no recall. Afraid I'm gonna get hit in the rear due to lack of power. Doesn't do it everyday but has happened twice in two weeks when I've pulled out onto a major highway with heavy traffic. I bought the car used in Jan.2023 with warrenty still on the car. Thought hey great deal! But now I think I bought a lemon.

I have taken it 5 times to the service center at Dealer in Rick Case in Plantation they have kept it for several weeks the last was returned to me on March 23. 2023 I was told it was fixed on April 22 2023 the engine light went back on the same problem the car keeps stopping I took it in, they did not even look at it. I was told that until June 14 they will not see or diagnose it. I have contacted consumer affairs with no resolution.

While driving home from my family’s house in the next town over. My car decided to have transmission issues I have had the car car for 3 years so far with now issues until two days ago when I heard a loud pop and my car stopped accelerating. Tried to put it manual mode and I watched the gears shift from 1st to 8th gear in seconds then get stuck in fifth the the check engine light came on. And I was stuck on the interstate for almost 8 hours while I tried to get it to move. The car turned over just fine and revved but no movement like it was stuck in neutral

I bought the car from the dealer when the car had a total of 12,000 miles on it the transmission would lunge the car forward at speeds around 70 mph. It made driving the car unsafe on the highway as I couldn't tell if it was going to lunge forward and hit the car in front of me, and I got it to the dealer. It was under warranty and the dealership tested it and said it needed to be replaced. When I got to 18,000 miles the new transmission had a similar incident and the dealership tested again and said this new transmission needed to be replaced completely. It is still under warranty and they will replace it in 3 weeks. I am going to be on the third transmission with a car under 20,000 miles. The transmission was only inspected by the dealership, and they told me that they do not know what was wrong they just pulled out the bad one and put in another, they did not take it apart to figure out what the problem was on the first one that needed to be replaced. I still have the car and can be inspected before I drop it off at the dealership May 6th. There were no warning messages on the dashboard or any other problems with the car. Information below is on the first incident, the second incident started around February of 2023.
