While driving my 2018 Hyundai Santa Fe Sport in freeway traffic, I felt the vehicle begin to heavily vibrate and the engine was jerking severely. The speed began to slowly descend. I was unable to control this. I was in a one-lane overpass, with no safe place, room, or lane to pull over. I felt hopeless and fearful for my life. I was literally drifting, praying the vehicle would be able to handle the descent upward. As the speed declined, the vibrations became more pronounced. No dash lights were illuminated. Other drivers behind me were approaching rapidly at the speed limit and slamming on their brakes and hazard lights in an attempt to notify drivers further back. I managed to maneuver over to approximately 24 inches of a faux shoulder on the right of [XXX]. Cars hurled past mine within inches of my vehicle. I knew I needed to get out of the car and crawled over to the passenger side. Again, I was trapped. Several HPD units were dispatched to literally shut down the freeway to enable a tow truck driver to safely hook up my SUV. I had it towed to my mechanic and he did a diagnostic indicating a compression issue. He ordered new spark plus and 4 new coils. Upon further investigation he discovered that Cylinder 4 was not holding compression and he informed me that the engine had failed. I then had it towed to the local Hyundai dealer. At check in, I was informed that there would be a $700 diagnostic/tear apart fee to discover what repairs were needed. I informed them exactly what was needed and I expected a new engine. The Hyundai mechanic dismantled the engine and took pictures, ran a few tests. He submitted the results to Hyundai for approval. The engineer at Hyundai denied a new engine claiming "the head coil is not part of the recall". I was told for $2500, Hyundai would "refab" my damaged head to control the leaks. If that repair didn't address the issue, I was sure to get a new engine. A financial and physical risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

I just got Hyundai SUV last December and already cause problem with engine and abs, after I found out that it is recalled a while ago. First ABS, I was going to fix that but all attention to me is engine light then found out it is High pressure fuel pump then burning oil that I smelled something isn't right. I feel it's not safe to drive and I spoke to mechanic, He told me take it back to dealership that they gave me a lemon Hyundai.. I talked to the dealership mechanic shop and never tell me anything how much for high pressure fuel pump? SO I already saw my SUV problem and I decided to check website for Hyundai recalled, that what I had right now.. It's only 6 years old and only 90,000 mileages on that SUV. That smell is very odd and it will cause engine fire..

While driving in the Highway, my car lost engine power and lead to my car run no more than 40 miles per hour, after this I took my car to the garage and the said it was the knock sensor that course this issue. After being in the garage, my car knock sensor was replace for a new one to make sure this was giving good reads and while driving in a two way street it happen again and I believe this could be very dangerous if it happen while passing another car on in a crossway. Yes. Yes. As soon it happen the check engine light started blinking. It happens 3 times end of Nov 2023, early December and late December 2023.

Engine died on highway. Noc sensor code indicates is a known problem for this engine. 2.4 liter Hyundai sante fe sport. Before engine died was burning much oil even after oil changes and borught in for recalls to dealer 2 mo before. Excessive burning of ooil wa a know issue at that time July 2023. Now Hyundai dealer saying the issue is a customer issue due to carbon build up on a valve. High burnin rate of oil is responsible for the carbon build up on the valve causing the engine to fail. Not a cusotmer problem but a engine design issue.

After buying my 2018 hyundai Santa Fe Sport this past June, I have been told the car has an oil consumption problem and is burning off oil quickly. For example, I have to add a quart of oil every 500 miles. The car has 98000 miles on it. No warranty with car dealer was established at time of sale

I had no warning lights or messages and then the engine threw a rod and my car just died on the side of the road. It had apparently been burning oil. I get it back after 2 months and it needs a battery. Now the check engine light is on and it has affected the catalytic converter.

April 17th 2023 my cars decelerate, wouldn't accelerate above 60 mph and would randomly decelerate as low as 15mph. The check engine lightvwas constantly flashing and the rmp wouldn't go above 2. I called motorworld and Hyundai. Motorworld said I needed a knock sensor replacement. They replaced the knock sensor. I called Hyundai again to see if I could be reimbursed. They said no. Hyundai then told me that because I paid to replaced the knock sensor my engine was now covered for life. A I ri 14th 2023 the exact same thing happened to my car again. I had it towed to motorworld. A week later I was told that they recommended an $800 oil consumption test because they said the oil was very low. I told them that my oil light never came on. The car was failing. I told the that I just had an oil change and that I thought the prior mechanic cheated me out of oil because my oil light came on 2 weeks after getting an oil change. This whole week I've been going back and forth with Hyundai re: this problem with is noted on websites. I was told that there is nothing they can do. I asked them to replace the motor. This is an engine problem and the engine is covered under power transmission and because I paid to replace the knock sensor. However it is not the knock sensor. The car did what it was supposed to do if tge engine is in danger of failing. So why did the charge me $583 for the knock sensor replacement and now they want me to pay $800 for an oil consumption test. It's obvious that the vehicle is consumption oil. There are no oil leaks. I spoke with Hyundai again yesterday. I told her that Hyundai needs to replace the engine and I feel that they stalling and putting me in danger. If this happens again I'm in danger, especially on the highway. Motorworld called to confirm that I was told on several occasions that because I paid for a knock sensor my engine is under warranty for life. Motorworld tod her that it's not. This occurred in April and again 5/14/23

The check engine light has gone on three times in the last 18 months. Vehicle has 62,000 miles on it. The first 2 times the issue was with the fuel injectors. All 4 injectors were replaced the first time about 31,000 miles on car and the 2nd time needed to cleaned manifold and reset injectors. today's issue was malfunctioning high pressure fuel pump that leaked into the crank case. The codes for the two most recent repairs are available at Lia Huyndai 645 central ave albany ny. All 3 cases have been confirmed by dealer (Fucillo or Lia). There is one common theme "fuel" involved in all of the warning light problem/code. I have also have a case opened in customer affairs with Hyundai Case #21254176

The acceleration of the vehicle from a stop. Whether from a stop sign, stop light, even sometimes after slowing down after a turn. It hesitates while the gas pedal is still being applied. Causing the vehicle to slow and other vehicles are forced to brake. The engine does not rev and the tachometer does not move. There are no warnings lights or vehicle notifications. After several attempts to bring it to the dealership, they are never able to replicate the issue. The OBD scans show no issues. It has never been a constant problem, however it remains as a "hit or miss" issue. Could be days of no problems and then popping back up every stop.

2018 Santa Fe Sport had been leaking a few little oil spots in my garage. First noticed the problem at about 80k miles. Took it for an oil change and the technician told us he had a lot of complaints on this model vehicle. Fast forward a few months at our next oill change (3 thousand miles later) and the technician told us we were almost completely out of oil. We took the vehicle to the Hyundai dealership and we were told there was nothing wrong, no oil leaks detected. We were then having to bring the vehicle in to the oil change place in between regularly scheduled oil changes and top off the oil (sometimes taking 3-4 quarts in between oil changes). Coming home from the ballpark a few weeks ago we exited the freeway and the vehicle started shaking and losing power and the check engine light came on. I coasted in to the gas station and checked the oil and the dipstick was bone dry (except for the oil that looked like it had burned to the dipstick). I bought / put in 2 quarts of oil and limped the vehicle home. Took the vehicle to the local Hyundai dealership and now we are being told we need a new 10k dollar engine and now that the vehicle has almost 120k miles it is no longer under warranty. Everyone I have talked to about the issue says this is a common thing for this make / model and that the engines need to be replaced. How is there not a recap for this? Any advise / assistance would be appreciated

I was driving a few months ago and after getting fuel my check engine light comes on. I drove it for a while and it cleared itself. About 3 weeks ago it came on about 50 miles after putting fuel into it and got it cleared by someone with obs II reader. Since then ive put about 2000 miles on my car and it came on again about 50 miles after putting fuel into it. I replaced the gas cap making sure it went on correctly but nothing. I smelt leaking fumes with the gas cap on. Im taking it to a repair shop tomorrow to have it looked at.

Severe acceleration hesitation after stopping, when making slow speed turns and after hitting slow speed dips or bumps. Vehicle gives intermittent warning of rollover or excessive vehicle angel. This occures during good weather conditions, however, this behavior creates collision and safety hazards, as the fuel system appears to be shut down as if a rollover has occured, when it has not!!

The contact owns a 2018 Hyundai Santa Fe sport. While driving with a half tank of fuel in the vehicle, it began to stall on the highway. The contact noticed fuel coming out of the exhaust and the vehicle ran completely out of fuel as she pulled over to the shoulder. The state police pulled up behind her and ordered her to get away from the vehicle due to the fuel and fumes. The vehicle was towed to M.J. sullivan Hyundai (452 broad St C, new london, ct 06320, 860-437-6179) where it was diagnosed that two fuel injectors were stuck open and caused the vehicle to stall. The contact noticed a large amount of fuel was in the oil pan due to the dipstick. According to the dealer, the manufacturer suggested that they replace the fuel injectors, drain the oil, and place new oil in the engine. The dealer stated that was all they would do to the vehicle. The contact called the manufacturer to get a case for a possible buyback. The manufacturer denied the buyback request and offered one month car payment to resolve the matter. The manufacturer suggested the contact reach out to the better business bureau. The dealer refused to provide a loaner vehicle. The vehicle was retrieved and driven to the contacts home. The failure mileage was 14,210. The VIN was unknown.

My car is 6months old with 7600 miles on it. I stopped at a red light. My car began to shake/shudder and then shut off. I had to try and restart it 4 times before it successfully restarted. This happened on a city street, thankfully right before getting on the highway.

Check engine light comes on and testing shows 3rd cylinder has as fuel-oxygen imbalance. Has happened twice. Light went off the 2nd time. Brand new car. It happened at 2,500 and 5,000 miles. Had it checked by Hyundai the first time and they didn't see any other problems, chalking it up to a malfunction. Someone told me it could be a bad fuel injector; bad sensor; or a miscalibration of the engine/fuel injector
