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 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.

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.

This vehicle has been having engine problems since January 2 023 the engine light is on the car stops running completely while driving. A great danger to me. 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. I wish to file a lemon law on this dealer since obviously it is defective beyond repair. please advise as how to take this action. I need a new reliable car. Thank You.

The engine is ticking as well as vibrating. Looked on the website to see if there were any recalls for this which every year other than the 2020 was having this issue - spoke with a diagnostic shop and they said have had newer models with the same situation and was able to turn over to Hyundai - which they replaced with no charge to the owner. It happens when it idles as well as when I am on the interstate.

The car has issues with starting, and accelerating. Dealerships have zero availability for weeks out to provide any sort of diagnostics, and are unable to assist with this issue. The following email was sent to Hyundai Customer Service: I am currently leasing a 2020 Hyundai Elantra.? In July of this?year, the car suddenly had trouble accelerating.? Being due for an oil?change, and wanting to get the?engine codes read, I contacted my local Hyundai dealership, and they had no availability for weeks.? I used a local service station to have the codes read/get the oil change, and the car continued to have difficulty (I am attaching the BlueLink reports on said codes).? I was finally able to bring it in to the local dealer who cleared the codes, and said they were the result of "not having enough oil."? The car drove well until 11/27, when the car started to sputter, not allowing it to accelerate?properly, and with multiple error messages, including a flashing engine light.? After contact my local dealer who I first used in July, they said "it is probably low oil like last time, these cars are known to burn oil quickly."? I again?brought it to my local service station for the oil change, and for a NYS inspection.? As my car is under 15k miles, and up-to-date with oil changes, I would imagine it would pass said inspection.? It did not.?

Since the onset of leasing this 2020 Hyundai Elantra, the check engine light appeared intermittently. I reported this to the dealer on Route 4 in Paramus, New Jersey. They advised me that they ran scans to determine what the problem was. On one occasion they stated a censor needed replacing, and later told me that was done. Thereafter, on Friday, August 26, 2022, I was positioned to bring the car in again because the check engine light remained on, and additionally, another dash light came on causing a loss of power and the car to stall. The dealership told me they ran another scan and found metal shavings in the engine, and the engine would need to be replaced.

2020 Hyundai Elantra. Consumer writes in regard to vehicle stalling while driving. The consumer stated, at low speeds, the vehicle would hesitate then lurch forward. The current mileage was 11,089. The dealer and manufacturer were notified. The consumer was informed braking with the left foot was the cause of failure. The consumer disagreed this was the cause, since the consumer has always driven this way in other vehicles.

What component or system failed or malfunctioned, and is it available for inspection upon request" The engine malfunctioned, then failed. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? I decelerated from 65 mph to exit a freeway. At the end of an offramp, I slowed to a stop sign where the vehicle malfunctioned. It jerked, violently, forward as I attempted to accelerate endangering pedestrians crossing the intersection at the stop sign, other drivers on the offramp, and myself. Has the problem been reproduced or confirmed by a dealer or independent service center" To date, 3/8/2022, the Hyundai dealership has not performed any diagnostic testing or repairs on the vehicle since receipt of the vehicle on 2/18/2022. Hyundai Motor America has also refused to acknowledge that NHTSA Campaign Number 21V301000 (4/28/2021) is associated to the vehicle. To date, I have made three (3), separate, follow-up attempts to communicate with an assigned case manager. The assigned case manager was unresponsive. After that, I made three (3), separate, case manager escalated supervisor requests. The case manager supervisor was unresponsive. My most recent request has been an initial Hyundai management team request (3/7/2022) -??I am waiting for a response but am not hopeful that anyone will respond. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others" The vehicle remains at a Hyundai dealership. I received a text message that read, -??the technician has had the vehicle, it has been starting and driving normally.-?? In my opinion, the vehicle is unsafe to drive. I cannot, in good conscience, operate the vehicle until it is safe to drive. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" A check engine light presented just before engine failure. The engine did not start after it failed. Remedy for the mechanical concerns is not yet avail

My car was in good working condition no lights were on in my car up until January 16, 2022, I went to get gas on a regular morning routine before going to work when I turned my car back on after getting gas and I began to pull into traffic and my car stalled and the engine oil pressure light and battery charge warning light came on. My safety could have turned out bad but grace of God my car allowed me to turn it back on and go to the closest location to me and that was auto zone. I got the car towed from there to a hyundai dealer (Preston Hyundai in hurlock, md) is where the car is currently being looked at.

Checked VIN for open recall and that number doesn't come up. My engine had to be replaced under factory warranty. The issue was the exact same as a current recall. I am concerned that Hyundai is not expanding the recall in an effort to downplay the issue. 2020 Elantra, 2.0 liter engine, stalling while driving. The tech found the piston rings were bad. I hope this will help others and Hyundai will be held accountable.
