| Jul 2024 | ENGINE | The contact owns a 2018 Hyundai Tucson. The contact stated that while starting the vehicle, the contact became aware of a loud knocking sound coming from the engine. There was no warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The dealer was contacted, and the vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 107,824. | Crash: No Fire: No | 107,824 |
| Jul 2024 | ENGINE AND ENGINE COOLING | The contact owns a 2018 Hyundai Tucson. The vehicle was taken to an independent mechanic for an oil change where it was determined that the vehicle was almost out of oil and there was an oil consumption failure with the vehicle. The vehicle was not repaired. The vehicle was then towed to a dealer where it was diagnosed that an oil consumption test, engine combustion cleaning, and an oil change was needed to be completed. The vehicle was repaired but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 59,000. | Crash: No Fire: No Towed | 59,000 |
| Jul 2024 | ENGINE | I was traveling on the freeway at Highway speed, heard a loud knocking sound coming from the engine that got progressively worse. No warning lights, began to loose power as I exited the freeway. Had vehicle towed to dealership, they were able to replicate knocking noise coming from bottom end of engine. Diagnosed as catastrophic engine failure and needs engine replacement, outside of standard warranty. Engine is a 1.6L GDI and model was not included in recall for KSDS sensor. Safety was compromised due to engine failure at high speed with no warning or previous engine problem. Vehicle is available for inspection as of current date | Crash: No Fire: No | Unknown |
| Jun 2024 | ENGINE | The engine consumes a quart of oil every 1,000 - 1,500 miles with no signs of leakage or burning. | Crash: No Fire: No | Unknown |
| Jun 2024 | ENGINE | Car had been burning oil very quickly. I took it for an oil change, before it was due, and they said it was very low. They changed it, and I was leaving to visit my parents in Florida the next day. I checked the oil when getting there, and it was good, and I also checked it prior to heading back home, and it was still good. I was in a really bad/unsafe area at 10pm, on my way home from visiting my parents, and my car began to stall. Engine light came on. It would stall really bad when going slow, and almost died a couple times at lights when stopped, but we made it home. We got it to a mechanic, and they stated it was the engine, and it needed to be taken to the dealership. I have read that Hyundai/Kia are notorious for engine issues. My car was towed to the dealership, and they supposedly requested to see if Hyundai would cover for a replacement engine. My car is unfortunately 10,000 over the warranty mileage (100,000), but 110,000 is still not enough to be already having engine problems. Supposedly, according to the dealership, Hyundai declined, and the quote for a new engine is $7,693, which I cannot afford, especially on top of my car payment, which I still owe a good chunk on. | Crash: No Fire: No | Unknown |
| Jun 2024 | UNKNOWN OR OTHER | The contact owns a 2018 Hyundai Tucson. The contact stated that while in a drive-through line and turning the steering wheel, the vehicle was shaking and vibrating.

There were no warning lights illuminated. The vehicle was taken to an independent, who stated there was no engine light illuminated, but the mechanic replaced the coils, oil, and spark plugs. The contact called the local dealer and left a message. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 108,000. | Crash: No Fire: No | 108,000 |
| Jun 2024 | ENGINE | I am dealing with engine failure after an out of pocket turbo repair cost | Crash: No Fire: No | Unknown |
| May 2024 | ENGINE | My engine failed while driving on a highway. The engine began ticking, and then completely failed. The tow truck driver reported oil leakage. I towed it to a mechanic and he said it was completely blown and irreparable. He reported this as a recurring problem with hyundai and kia cars that "eat up oil" and then damage the engine. The oil light has not been on, I've gotten regular oil changes and was within the distance of my most recent oil change. But apparently it was leaking, failed to inform me and now I have to purchase a new car or pay for a new engine. I looked up recalls, there are none. I looked up class action settlements and my car was mysteriously not on the list based on the VIN, despite being listed within the model and year range. | Crash: No Fire: No | Unknown |
| May 2024 | POWER TRAIN,ENGINE | End of April/beginning of may, driving down highway check engine light flashing loud knocking and loss of power. Got it towed by AAA. Wasnt able to make appt until May 9th. Got it towed to the Hyundai dealership. Got phone call that is filed the bearing test and need a total engine replacement. Was told by the dealership that it could take 3 months or more to get an engine in and get it replaced. They have no loaners, and hyundai expeacts me to pay out of pocket for a rental for work to keep my job as well as my independent contracting job accounting/taxes. I have to have a vehicle. A rental is easily 1200+ a month. Hyundai refuses to give me a trade in value for my vehicle until the new engine is in. Hyundai also refunded to reimbursement me for a rental until all work is completed and a work order is in hand ( which can be many many months) I dont have money to pay 1200+ a month for a rental and also pay by car payment every month for a vehicle that is stuck at the dealership undrivable because Hyundai installed faulty bad engines. I am stuck and all Hyundai can tell me is that it takes months for the engines. Purchased the vehicle in Feb 2022 and have perfect maintance records, service records and everything else for upkeep. Still owe 15545 on the vehicle and its undrivable. So im paying a car payment on a vehicle that Hyundai made undrivable | Crash: No Fire: No | Unknown |
| May 2024 | ENGINE | KSDS engine software update was performed by Hyundai dealer on January 22, 2024. On or about February 11, 2024, the vehicle began stalling, intermittently, and would not restart for several minutes. On March 4, 2024, the vehicle stalled and, upon restarting, after nearly a 30 minute wait, it would not exceed 35 mph. The vehicle registered, nor recorded, any diagnostic codes at any time, during these events. The vehicle was taken to Edwards Hyundai service center for diagnosis and repair. No diagnostic codes were recorded in the vehicle history. Upon inspection, Edwards changed a loose timing chain and exhaust camshaft. The vehicle was picked up on 3/13/2024 and presented with the same issue on 3/14/2024, with the engine stalling and failing to restart for several minutes. When the vehicle did restart, it would not exceed 35 mph. It was then returned to Edwards Hyundai on 3/15/2024, where it duplicated the issue for Service Writers, failed to restart, and had to be pushed out of the service garage. The vehicle has since, without further diagnosis or repair, started and ran for technicians, who have since supposedly driven, approximately, 200 miles, in an effort to determine the issue. Edwards Hyundai then demanded the return of a loaner vehicle, in an effort to force us to retake possession of the vehicle, having failed to properly diagnose or repair the issue. A complaint has been filed with Hyundai corporate, which resulted only in them also trying to convince us to accept return of the vehicle in said state of disrepair. It has since become very clear, as evidenced by numerous reports of Hyundai vehicles experiencing the same effects and mechanical issues, after receiving the KSDS software update, that Hyundai, both at the corporate and service level, have been dishonest, as to being unaware of the cause of the issue and what must be done to resolve it. Given that the potential end result of the customer retaking possession of the vehicle in its | Crash: No Fire: No | Unknown |
| Apr 2024 | ELECTRICAL SYSTEM,ENGINE,LANE DEPARTURE | Bought car [XXX] blew up 2 weeks later knock censor was not put on by first dealership so engine blew on interstate car was possible on fire due to as much smoke was coming from vehicle could of been rear ended engine failure due to that no warning of engine failure tucson knows all these problem and is currently in a class action lawsuit and have known the problem for years dealership had to of known this was going on with this engine but sold the car to unsuspecting consumer i think there was a lot of stuff going on this car was owned by stew hansons then sold to dewy ford to sale which my understanding is they own both dealerships. My safety and anybody that gets into my vehicle is still have a 50/50 chance of it happening again ! Have done a lot of homework and watched many youtube videos of these vehicle burn to the ground even one death . they are death traps and should not be on the road . im scared to put my grandchildren in it due to all the info i have obtained INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Apr 2024 | STEERING,POWER TRAIN,ENGINE | My vehicle had been in the shop for 30 day due to engine shutdown in the middle of the road, I barely was able to get vehicle off the road and avoid oncoming traffic. I got my vehicle back and driven it a total of 40 minutes within a 3 day time period. During my drive to work my vehicle shut off in the middle of the highway and would not turn on again. My concerns are not being taken seriously with Hyundai and it is a disaster waiting to happen. I have a one year old daughter and I can not risk her safety as well as the other on-coming people on the road when it quits and oncoming traffic has to swerve to not T-bone me. Hyundai will not take any action to correct this other than giving it a temporary fix of a 45 minute drive before they allow me to get back on the road and put myself and others at risk of injury. | Crash: No Fire: No | Unknown |
| Apr 2024 | POWER TRAIN,ELECTRICAL SYSTEM,SERVICE BRAKES | ABS SENSOR, downhill light, traction control light stays on. In August 2023 the transmission had to be rebuilt from slipping.

| Apr 2024 | POWER TRAIN | While on the highway going 70mph the check engine light flashed on the immediately off out of nowhere and car started aggressively shaking before loosing temporary power. My wife and toddler were in the car and we were all pretty shaken up. Luckily I was able to gain control of the car but I'm concerned that another issue may occur. I immediately took my car in to the shop and they were unable to replicate the issue. Spark plugs, oil, transmission fluid and coolant fluids were all as regular maintenance but no real issue was addressed. My car has also had issues with struggling to accelerate from stop, causing jerking motion and my oil seems to be burning faster than usual. | Crash: No Fire: No | Unknown |

| Mar 2024 | ENGINE AND ENGINE COOLING | The contact owns a 2018 Hyundai Tucson. The contact stated that while operating the vehicle, the check engine warning light remained illuminated. The vehicle was taken to the local dealer who diagnosed that an emissions leak was present causing the engine light to illuminate; however, the cause of the emissions leak was not yet identified. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 74,000. | Crash: No Fire: No | 74,000 |
| Mar 2024 | ENGINE | Spun bearing in motor at only 32000 miles poor oiling. Same as other years and models of Hyundai. 2.0L engine | Crash: No Fire: No | Unknown |
| Mar 2024 | ENGINE | There is a known issue with this particular engine burning oil. I’ve had to replace three catalytic converters, among other parts in the exhaust. I am 3000 miles away from an oil change and my engine is flashing lights and stalling while running. Something needs to be done as it can cause the engine to fully fail | Crash: No Fire: No | Unknown |
| Mar 2024 | ENGINE | My wife was picking up our daughter from school. The car shutdown as my wife was getting into the left hand turn lane to go onto our main street. The warning dash lights turned on, but she could not turn on the car. She called me and I left work early to help her out. She called me a few minutes later telling me she was able to get the car started but that it sounded as though "rocks were in the engine." When I got home, I opened the hood and checked the dip stick and noticed metal flecks and shavings on the end. I tested the dipstick 3 more times and each time I inspected it noticed the flecks and shavings. I then called a tow truck to have the car transported to Hyundai. The sudden engine failure led me down a rabbit hole online and realized this is a widespread issue with a lot of Hyundai vehicles. Luckily, the dealership is replacing the engine since it is still under warranty. I plan on getting rid of the vehicle as soon as possible. The quality of their engines is awful. Despite taking the car for regular maintenance it still failed. It's also telling that the dealership I'm at has several other Hyundai's they're servicing FOR THE SAME EXACT ISSUE! I was also informed it can take up to a month for the engine to be replaced. Stay away from Hyundai and Kia. There's a reason why they have the types of warranty's for their vehicles. They know they're unreliable and faulty. | Crash: No Fire: No | Unknown |
| Mar 2024 | ENGINE | The engine in my 2018 Hyundai Tucson is burning oil at an excessive rate. I have to change my oil every 2000 miles or less due to engine knocking if I don't. Due to the excessive oil consumption, I now have to replace all 4 engine coils for over $1500. There have been multiple codes given to me every time I take the car in, including 3 times for the knock sensor which was replaced under a nationwide recall. Hyundai settled a class action case with some consumers, under the radar, for excessive oil consumption and is leaving every other consumer unaware unless they start digging for information. One of the times my engine light came on, I was on a very busy California highway and my car went into limp mode. This is unacceptable and a major safety hazard. My car is currently at the dealership for the third time and not drivable until I spend $1500 to repair a problem that their faulty engine has caused. | Crash: No Fire: No | 105,097 |
