Car was fine and I get regular oil changes. Last week all the sudden the car started making noise and just shut off. When my husband checked there was no oil on the dipstick but I park on concrete and the car is not leaking oil. Apparently the motor is blown and completely locked up.

I've taken the vehicle to several mechanics for engine-idling when turning, going up-hill. I've purchased new plugs, lines, engine cleaners, no-one can figure it out. The oil now has engine shavings even though the oil was recently changed. The car broke down today.

As I was driving I was stopped & told my car was on fire. I immediately stopped & hopped out & less than 30 seconds later half of the hood caught heat/fire & flew into the windshield breaking it. At least half the car is burnt to ashes.

I purchased this car [xxx] as a cpo vehicle from a Ford dealership. By [xxx] the oil pressure light would flicker and it was clear the car was burning a lot of oil between changes. On 8/22 an oil change was completed at dealer. On [xxx] the oil pressure light flickered and it was three quarts down. An oil consumption test was started at 112,000. On sat [xxx] while driving to dealer for oil check, the car began shuddering violently and the check engine light came on, and went into limp mode. I was on a dangerous mountain pass at the time and it could have been a major issue. The day before a tractor trailer had almost run me off the road, if my car had stalled then I might not be here. Hyundais have a known issue with oil burning and engine damage. Right now I am stuck in a 14k loan with a car that is unsafe to drive. I am not sure what the dealer plans to do, or what the diagnosis is, but its clear these engines are not safe. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving on interstate for approx 30min and the car stopped accelerating. We safely merged off to the side and the car completely shut off. The car would not start. We put oil in and it started up by engine light was on. We got vehicle towed 1hr back into town. We are lucky no cars were behind us to cause an accident. We are also lucky engine did not catch on fire. This happened completely out of the blue. I get my vehicle serviced regularly and serviced at Hyundai dealerships for major repairs. The engine failed us and is available for inspection. Our claim was denied by Hyundai due to my mileage being 10k over the warranty. However they installed the faulty engine so regardless of mileage this needs to be resolved.

2018 Hyundai Tucson has excessive oil consumption. Burns multiple quarts of oil per 1000 miles. Hyundai refuses to remedy the oil consumption. Oil consumption has also led to having to replace the catalytic converter due to oil burn off.

Engine started making a knocking sound, then the oil light came on followed by the check engine light. Accelerates and decelerates on its own. Was forced to immediately pull over across three lanes on interstate 95. It’s been over two weeks and I’ve yet to hear if Hyundai is going to cover a replacement engine. However, what happened is exactly what they have listed on their website ?? what to look out for check-engine check engine oil-light engine oil pressure a knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the “check engine” light in the instrument cluster. Illumination of the “engine oil pressure” warning lamp.

Excessive oil consumption leading to catastrophic engine failure.

The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 95,000.

Engine ran out of oil with no indication on instrument panel that it was happening. Engine now knocks and needs replacing. My independent service center has determined a failure. It is available for inspection.

I am submitting this complaint regarding an ongoing and dangerous issue with my 2022 Hyundai Tucson involving repeated fuel injector failures that have caused the vehicle to stall and lose power while driving, without any prior warning indicators. The first incident occurred in October 2023, at approximately 16,000 miles, when the car suddenly died while I was driving. There were no warning lights or signs of a problem before the stall occurred. The vehicle had to be towed to the dealership, where they replaced two fuel injectors. Just two weeks later, the same issue happened again—the car died while driving and was towed back to the dealership. The remaining injectors were then replaced. Unfortunately, this problem has continued. In November 2024, at around 26,000 miles, the vehicle again stalled while driving, with no warning, due to another fuel injector failure ( more failed injectors). Most recently, on October 18, 2025, with 31,000 miles on the odometer, my Tucson lost power and died while I was merging onto an interstate—once again with no warning or alert of any kind. I am still waiting for confirmation of how many injectors have failed this time. This is an extremely serious safety hazard. Losing engine power unexpectedly, especially while merging into highway traffic, puts both the driver and others on the road at significant risk of a collision or serious injury. Despite multiple occurrences, Hyundai has not identified the root cause of the injector failures and continues only to replace the faulty parts, which clearly does not resolve the underlying issue. It is unacceptable that a relatively new vehicle would experience repeated fuel system failures of this nature, and it is clear that there is a systemic defect affecting safety and reliability. I urge the NHTSA to investigate this issue to determine whether other Hyundai Tucson owners are experiencing similar failures and whether a recall or safety action is warranted.

My family’s safety is at serious risk with my 2021 Hyundai Tucson, which I’ve owned only 55 days. This vehicle has stalled three times while driving, putting me and my two young children in immediate danger. Each time, the car operated normally until a flashing engine light appeared, rpms spiked, and the vehicle suddenly lost all power—entering “limp mode” and unable to exceed 3,000 rpm or 50 mph. The first failure occurred 9/14/25 while merging onto the interstate, forcing me to lose power mid-acceleration as surrounding vehicles slammed their brakes to avoid collision. 13 days later, it happened again in stop-and-go traffic, leaving me stranded on the shoulder. Both incidents occurred without warning or prior check-engine lights. The third—and most terrifying—incident was on October 17, 2025, when the engine completely died 300 miles from home on a busy highway. My children, ages 4 and 6, were terrified as cars sped by. We were extremely fortunate not to have been hit. I am urgently requesting assistance for the immediate replacement of this vehicle’s engine. It is covered by Hyundai’s 15-year/150,000-mile extended warranty, clear evidence the company was aware of these issues. Service records from the previous owner-that I was told about by Hyundai show ongoing engine problems and recalls since 2022 further proof this vehicle should have been retired from service as a parent, I’m very alarmed that Hyundai refuses to act until “catastrophic damage” occurs. This policy is irresponsible and endangers entire families. There’s at least 50 NHTSA complaints describing identical issues; stalling, power loss, and bearing failure linked to defective connecting rod bearings. Yet, Hyundai has denied a replacement, insisting on waiting for further damage and failures in operation. I beg you to intervene and prioritize my family’s safety before tragedy inevitably strikes. My children should not be put at risk due to corporate negligence, greed and absence of accountability.

My 2018 Hyundai Tucson 1. 6 turbo (VIN [xxx] , 113,000 miles) burns oil excessively and was deemed to need full engine and turbo replacement ($15,382. 95). Hyundai refuses responsibility (case #xxx). This is a widespread defect that causes potential loss of power while driving. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Only confirmed by the lot I bought it from since Hyundai refused to look at it.

High oil consumption, taken to dealer for oil consumption test, have to drive vehicle 1000 miles , then take vehicle back to dealership to see how many quotes of all I’ve burnt or lost recheck oil levels.

My 2017 Hyundai Tucson has completely broken down will not go into reverse had a diagnostics at Hyundai. I thought it was going to be covered because of the class action suit. My car apparently was not in the recall or the suit. I don’t understand I have the identical problem of the dual clutch transmission issue. I’ve tried to get Hyundai to do good-faith repair they refused. I’ve contacted carmax where I purchased the vehicle. They had the car when the lawsuit was finalized I didn’t know anything about the lawsuit or the problem with the vehicle. I’ve had the car for five years it’s at 85,000 miles. I don’t know what to do.

Beatriz duran scarlett. B. Duran@gmail. Com 734-360-5857 313-917-0531 vehicle information: • VIN: km8j23a40ku841552 • year: 2019 • make: Hyundai • model: Tucson • mileage: 132,303 problem description: on oct 11, 2025, my 2019 Hyundai Tucson entered limp mode on the freeway, losing power suddenly, posing a safety risk. This followed a dealership visit a couple months ago for a recall engine repair (possibly 21v-727). They returned the car with a check engine light, claiming it was a false error needing a reset on my next visit. No reset was done. On oct 11, the limp mode forced a tow back to the dealership. They now demand $300 for diagnostics and refuse a loaner, claiming it may not be warranty-related. I’ve escalated to Hyundai national team case number : 41621677 with no resolution after four days. This feels like a safety defect tied to the prior recall work.

On October 11, 2025, I discovered that my 2019 Tucson had no engine oil. I put three quarts of oil in at that time. Fast forward two weeks, October 25, 2025, and the dipstick read dry again, prompting more oil to be required. Unfortunately, I'm passed the 30 day warranty with the dealership I purchased the vehicle from so now this burden has fallen on my shoulders.

Vehiclr has been doing this since 4 montbs after purchase, then a recall came out we were told it would fix the problem. 3 times now since the recall the odometer screen and media screen will go blank while your driving. The car wont accelerate, turn signals, and steering colum becomes hard to operate properly. We have had to near accidents 1 being less than 2 hours in August of 2025 after Hyundai just claimed to repair the issue. We were driving on [xxx], screen went out, we lost full control of steering, had to wrestle with the wheel to keep car in its lane, we were almost hit by semi truck and ran off road. We immediately took car back to dealership, and shop assistant mgr was able to see for himself, it wasnt working after theu just made repair. They kept car a few days we were very reluctant to take vehicle back, out of these safety concerns, and my family having to ride in this vehicle. We took ot back as the dealership assured us the matter had been taken care. Then last week on [xxx], in the evening was driving down street and the screens started to flicker and the car wouldnt stay centeryed in the lane, then it happened both went blank, the car slowed down and the fight began on operating vehicle. In regards to no turn signal would go off, it wouldnt accelerate, the steering wouldnt operate correctly, if o wanted to center the car in the lane, it would pull the car another direction. A 7 minute ride home took over 20 minutes. We took car back to world Hyundai matteson, the next morning and called Hyundai corporate office to inform them we didnt want the vehicle back.

Vehicle propulsion system failed, as a result vehicle rolled down an inclined driveway in to the street and was stuck in the middle on the street in traffic. Vehicle had started normally, was able to shift into drive, no obvious warning lights or error messages displayed. Vehicle would shift into drive/park/reverse as required but would not move. Upon shutdown an restart two warning lights were display but vehicle would still not move. Vehicle only had 168 miles on the odometer. Vehicle is a hybrid, engine was running and battery charged. Apparently the problem was a failed "over the air software update", this was corrected by dealer (see attached file). Safety issue is that the vehicle, 1 failed to display any error regarding a failed update, 2 failed to immobilize the vehicle allowing to move in an unsafe state, 3 failed to notify owner that updates had been done, 4 proceeded with an over thew air update that could potentially place the vehicle in an unsafe state.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving 75 mph, the vehicle inadvertently lost motive power and was unable to accelerate above 35 mph, prompting the contact to discontinue driving the vehicle. No warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed failures with the engine knock sensor and catalytic converter. The contact was informed that the vehicle was consuming an abnormal amount of engine oil. The vehicle was repaired. The manufacturer was notified of the failure, a case was opened, and the contact was provided with goodwill assistance. The failure mileage was 70,000.
