Dealer completed update 9C2 Theta 2 emissions update. After update, the car sputters slightly and increased noise is heard from the tailpipe. Customer returned to dealer after driving the car in different temps and noted the above complaint. Dealer verified the complaint but continues to take no responsibility for the fault on the repair receipt by writing condition is “normal” and recommending “customer to allow vehicle to properly warm up for one to three minutes prior to driving.” The last line of the service record indicates “no problem found at this time.” A template letter from Hyundai was attached to the repair record. Hyundai may be instructing dealers to not document problems in the service records assumably so they will not be liable for future litigation. It should be noted that owner was previously denied payment on their 2017 Hyundai Tucson due to lack of documentation by the dealer to prove the case with prior class action lawsuit despite years of verbal complaints to the service staff. Dealer may be intentionally not documenting or taking responsibility for systematic failures in the Tucson in service records. This may be on the direction of Hyundai corporate. 2020 Hyundai Tucson continues to sputter periodically during normal driving conditions. Car is parked in an attached garage making a 1 to 3 minute warm-up time-consuming and possibly unsafe. This required warm up should not be considered normal as indicated on the repair record. Hyundai should take responsibility for their shortcomings and allow proper documentation on service records rather than pushing the fault on the owners. As with previous Tucson complaints, the dealer continues to indicate the problems are the result of owner actions not internal failures.
NHTSA complaint #11755723 — an unverified report by a vehicle owner.
While driving the car stalled and then the engine shutdown, caused by a misfired fuel injector. Myself and the passengers in the car were minorly safe, as this incident occurred while driving through the Yellowstone National park; having to pull over on the side of the road with no shoulder. The Woody Smith Hyundai Dealership in Idaho Falls confirmed that the feul injectors had misfired, and then replaced them. Prior to the failure, there was no warning until the car was actively stalling and failing (battery light and check engine light came on).

I was driving on the highway going 65 mph and scared when the engine started clicking and shaking a tiny bit. Plus it was slowing down no matter what i did. Well in a 4 lane highway. There was No engine light, no previous issues. The car drove great until this issue. I had the car only 3 months. Now i am afraid to drive it because i had seen theres an engine recall online for my car. Once i saw the recalls i tried calling alot of my local Hyundai dealer ships and they denied me because of the mileage.when i bought the car it was at 180 mileage. At this point i am not sure what to do with the car, i am hoping it can get fixed.
NHTSA complaint #11751801 — an unverified report by a vehicle owner.
The Core Symptoms: "The high-pressure fuel pump is leaking internally. Raw gasoline is flooding into the engine oil crankcase, causing severe fuel dilution. The engine air filter is physically soaked in raw fuel and smells strongly of gasoline." My engine is always extremely hot after I have only went 15 mins away from home. Sometimes takes over two hours to cool down. The Safety Risk: "When attempting to accelerate, the vehicle experiences severe fuel starvation, causing the engine to bog down and act like it is going to stall in the middle of traffic, creating a severe crash hazard. Additionally, there is a loud 'popping' sound/mini-backfire upon turning the vehicle off due to unburnt fuel vapors, presenting a high risk of an underhood engine fire. I have only 83,000 miles on my car.

I was on the highway on the way to work when my car started stalling. Every time I pressed the gas to give it some power, it would not go anyway where. after getting it towed to get looked at some of the fuel injectors failed and were misfiring. The warning message about ‘check engine’ popped up 2 minutes before it happened. this is the third time now in less than 6 months.

NHTSA complaint #11748709 — an unverified report by a vehicle owner.
I became aware of a Technical Service Bulletin that Hyundai published in Jan 2025 acknowledging that many vehicles (of which mine is one) have a faulty fuel injector and it will fail. Hyundai elected to not issue a recall on this issue so the public has no idea they are driving vehicles that are just awaiting for a malfunction in their engine. It appears the reason Hyundai is doing this is because fuel injectors are only covered on the manufacturer’s limited 5-year 60,000-mile warranty so they are hoping the faulty injectors last long enough to get beyond that point and customers don’t know the injectors were even faulty to begin with (because TSBs are not public knowledge). Hyundai can then charge for full repairs and omit admittance that the injectors were faulty and blame it on wear and tear. Mine failed beyond 60,000 miles and I am in this predicament. I imagine most customers with 2022 vehicles have not driven as much as me and haven’t had this come up. It seemed like something I should inform someone about. Do with this what you wish

#1. This vehicle uses a lot of oil !!! It burns through it like crazy I have to check the oil every other day. #2. When I come to a stop while driving and give it gas to take off IT WONT GO !!!!! It hesitates and when it does go it LUNGES FORWARD!! This is a huge manufacturer problem not a buyer problem. The engine is junk.! 3. I’ve called numerous places to get help. This car needs to be recalled. This is a huge safety violation. It doesn’t wanna go when you give it gas and when it does, it lunges forward that can cause a huge accident on the highways. This car was made in China. It is junk. I’ve called to get help with this issue and no one wants to help. Nobody returns my calls and I’ll Hyundai wants to do is it even more money out of me when this isn’t my fault the car is junk. For safety concerns I would like someone to call me at [XXX]. This car needs to be recalled and my daughter has one. It’s doing the same thing except hers is a lot worse. Hers is further advance where it’s actually stalling in the middle of the road while driving huge safety violation.

NHTSA complaint #11746594 — an unverified report by a vehicle owner.
On 3 occasions over my 18-month ownership of this certified pre-owned Hyundai 2022 Tucson, the vehicle surged suddenly forward WITH BRAKE APPLIED at creeping (parking) speeds of 3-4 mph. No warning lamps were observed. On the most recent (3rd) occasion, a crash over a sidewalk and into a storefront caused $10,000 damage. No pedestrians were harmed, no airbags deployed and neither passenger was harmed. The service department is "unable to duplicate" the surging behavior and declares the car mechanically "safe to drive."

My car is burning oil. I have returned multiple times to have it serviced and checked for leaks, but no leaks have been found. Before reaching the recommended 3,000-mile oil change interval, the oil level drops below the minimum mark on the dipstick. In addition, my engine has started making a knocking noise, which is very concerning.

NHTSA complaint #11739618 — an unverified report by a vehicle owner.
UNKNOWN -A catalytic converter clogged after being installed - only 14 months following installation, causing rough and unsafe acceleration, inability to shift gears properly, and need to drive with hazards on. It is clear that there is an issue with the engine/exhaust and system in this vehicle. Additionally, the car needs oil added regularly and seems to be burning it, as indicated by low level.

On March 21st, while driving my Hyundai vehicle, I noticed the vehicle began making a ticking sound. After stopping the vehicle, it slowly began catching on fire. The fire ultimately spread and resulted in the vehicle becoming a total loss. This created a serious safety concern and placed me at risk. I later learned there was a recall associated with the vehicle. However, I never received any recall notices because Hyundai reportedly had the wrong address on file. Had I been properly notified of the recall and potential safety risks, I would have done everything in my power to ensure the vehicle was inspected, repaired, and safe to drive. Because I was unaware of the recall issue, the vehicle continued to be operated without my knowledge of the potential danger. The incident caused significant financial and transportation hardship, including loss of reliable transportation and additional financial strain. Hyundai later reached a determination regarding the matter, but I remain concerned about the serious safety risk and the fact that I did not receive proper recall notification before the incident occurred. I am submitting this complaint because I believe the recall notification process and handling of this matter should be reviewed further due to the serious safety risk involved.
NHTSA complaint #11737337 — an unverified report by a vehicle owner.
My 2017 Hyundai Tucson is experiencing dangerous, sudden engine stalling, which are symptoms directly matching Service Campaign T1B. These critical safety issues surfaced following a total engine replacement in June 2025. Despite the vehicle being within the 12-month/12,000 mile workmanship warranty, the dealership is refusing to honor this coverage or offer goodwill assistance. My claim is based on a documented pattern of physical and technical negligence: - Failure to Update Software: The dealership failed to perform the mandatory ECM/TCM software integration (Campaign T1B) during engine swap, which is required to prevent the exact stalling I am now experiencing. - Dismissal of Warning Lights (Code P0456): One day after the engine replacement was “completed,” I returned to the dealership because the Check Engine Light illuminated with Code P0456. This was dismissed by the service provider without a proper diagnostic resolution, despite being a direct indicator of improper vacuum line reconnection during the engine installation. - Mechanical Negligence (Coolant Leak): Post-engine swap, the vehicle developed a coolant leak, which was a direct result of improper reassembly. Additional proof of the lack of due diligence during the repair. The lack of follow-through, combined with the dismissal of a life-safety defect and poor physical workmanship, suggests a total failure in the case management process. I am urgently requesting assistance to resolve this hazardous situation.

Sitting at a red light the vehicle seemed to almost stalled then lunged forward about eight feet almost colliding with the vehicle in front of me. To my knowledge the vehicle has not been inspected by the manufacturer nor has the problem been reproduced by a dealer or independent service center. To my knowledge there were no warning lights, messages or symptoms. I am somewhat unfamiliar with this vehicle since I've only owned it for 5 days. I picked it up on 4-25-26.

1st Incident: Merging on to the freeway car started to stall but was able to safely make it off the freeway at next exit. Less than 2 miles was unable to accelerate to properly merge on freeway. A slow merge & slow driving on to a freeway is extremely dangerous. 2nd Incident: 6 months later, Nov. 2023. Driving about 65-70 MPH on the freeway with my son, the car started to stall again. I was able to safely move from the 2nd lane, to the shoulder. Waited over 2 hours in the dark for AAA to safely move us. 1st time documented issues with Hyundai dealership. Fuel injector was main issue and was replaced. No check eng light. 3rd Incident: May 2024 was driving about 75MPH in the fast lane when the car stalled. I was unable to move fully out of the lane as the car just died. I was half in the shoulder and the fast lane. I was crying with fear while I had to wait for CHP to move me. Multiple times feared other cars would hit me at 80MPH+ while I waited 30mins+ for CHP to stop traffic and move me to the shoulder. Took the car to the dealership for the second time to be "fixed" for the same issue as Nov. 2023. Fuel injector, and catalytic converter were "replaced". This now being the second time for the fuel injector issue. No check eng light. 4th Incident: April 2026 driving on a school night home from dinner with my son at about 9:45pm. It was raining and was traveling at about 55MPH on the highway. Car started to stall/ shut down again. Was able to go about15MPH to a safe spot and waited for assistance late at night. This happened on a highway where people tend to drive recklessly and try to pass other vehicles which causes a lot of head on collisions, [XXX] . Vehicle was towed to Hyundai dealership for the 3rd time & 3rd time documented for the fuel injector and 2nd for the catalytic converter. The vehicle's main purpose is to safely transport and I've had nothing but nightmares and put in extremely dangerous situations with my son.
