ENGINE
Excessive oil consumption caused engine failure on December 17, 2025. My truck stopped and I was stranded on Highway I55 South for 4 hours. Hyundai and the Extended warranty has denied fixing my truck. It is still at [XXX] Hyundai as of today. Hyundai’s failure to properly diagnose or repair this issue when it was first reported under warranty has caused financial burden, diminished vehicle value, loss of use and inconvenience, and emotional distress and stress. This is a legitimate safety concern. I am demanding resolution of an ongoing excessive oil consumption defect in my 2016 Hyundai vehicle. This defect began while the vehicle was under warranty and has continued despite proper maintenance and compliance with Hyundai’s service requirements. I expect Hyundai to honor its legal and contractual obligations without further delay. Please contact [XXX] [XXX] Hyundai) @ [XXX] for details regarding repairs, oil consumption tests, etc. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2020 Tucson Sport with 82k miles. Since new, it consumes 1US qt. of oil every 6 month, although I religiously do the tune-up on its recommended intervals using only Mobil 5w-20 synthetic oil. What can I do?

Dear Commissioner and DMV Officials: I am writing to formally address a serious financial and safety concern affecting vehicle owners in Connecticut. As a driver with over 50 years of experience—32 of those in CT—I have never experienced rodent damage to any vehicle until purchasing my 2023 Hyundai Tucson. Since acquiring this vehicle, I have suffered thousands of dollars in damage from rodents chewing through the wiring and wire housing. Multiple mechanics have confirmed this is due to manufacturers switching to soy-based and plant-derived biodegradable materials in wiring insulation. These materials are effectively edible, attracting rodents year-round—not just in cold months. This is not owner negligence. The root cause is a material deficiency in the vehicle's manufacturing. Consumers should not bear the financial burden of a known design choice made by the automaker. Repairs are costly, often excluded from warranties, and frequently not covered by insurance. I respectfully request the Department: Investigate the scope of rodent damage complaints linked to bio-based wiring in newer vehicles. Coordinate with NHTSA to evaluate whether this constitutes a safety defect warranting a recall. Advocate for regulatory standards requiring rodent-resistant wiring materials. Urge manufacturers like Hyundai to offer warranty coverage, reimbursement, or retrofits for affected vehicles. I am prepared to provide documentation of my repair expenses upon request. Thank you for your attention to this matter. Respectfully submitted, [XXX] cc: NHTSA, CT Attorney General, CT Consumer Protection, Hyundai Consumer Affairs INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: BLIND SPOT DETECTION, ELECTRICAL SYSTEM
Blindspot detection did not pick up car on my right side two times. Front collision warning is effected by the angle of the sun at certain times of the day. Dashboard dims randomly. Could be for a minute or much longer. Could dim on and off, or stay dimmed for over twenty minutes. Brought the car in twice for this problem. Claimed nothing found and tech reset the codes. Bought it in two weeks later, stating problem not fixed. Told them to check connection, suggested they might want to replace the cables, and its a known problem. Again, reset the codes. Only this time they fiddled with the dimmer control on the console and I can no longer adjust the setting.

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
At dusk I was driving below the speed limit (40 MPH). I was at least 3 car lengths behind the vehicle in front of me when i saw the driver was braking because his brake lights came on and there was an intersection ahead with a stop light. There were at least two cars ahead of the vehicler I was behind. I braked but the car kept on going and appeared to accelerate. I was unable to stop the car with the brakes and collided with the car ahead. It was a sturdy vehicle with a strong bumper so I did not do much damage, if any, to the vehicle but my car requires $6,645.90 of repairs. No one was hurt and the air bags did not deploy. I was wearing my seat belt. There was no warning from ny vehicle that I was getting too close to the vehicle ahead and my car made no attempt to brake automatically. It was as though all warning indicators were not functioning. I have had two other incidents of the car surging ahead but did not report it because no one else was involved and I was able to correct the speed and I thought it was just my imagination.

ENGINE
I am writing this letter to formally document a series of catastrophic safety failures and gross negligence regarding my 2018 Hyundai Tucson. On two separate occasions, including as recently as Wednesday, February 11, 2026, I narrowly escaped a fatal high-speed collision because this vehicle entered "Engine Protection Mode" while traveling at highway speeds. Incident Timeline: Previous Service: I have visited Courtesy Hyundai of Tampa twice for engine-related symptoms and code P0087. They replaced the knock sensor and assured me the vehicle was safe. Safety Incident (Feb 11, 2026): While driving on the highway, the vehicle suddenly lost power, dropping to 60mph and 2000 RPM (Limp Mode) in heavy traffic. This sudden deceleration nearly caused a high-speed rear-end collision. Current Status: The vehicle is currently at Brandon Hyundai (as of Feb 13, 2026). I have been told a review will take 3-5 business days, leaving me without safe transportation or a loaner vehicle. Negligence and Liability: Courtesy Hyundai of Tampa was aware of the recurring P0087 code and engine performance issues. By clearing codes or replacing minor sensors (knock sensor) without addressing the underlying high-pressure fuel or internal engine failure, they released a dangerous, defective product onto the road. This vehicle is clearly covered under the Theta II GDI Engine Settlement and Service Campaign 966. The local dealerships are willfully avoiding a necessary engine replacement to save on internal costs, despite knowing the vehicle is prone to sudden failure. Demand for Action: Immediate Loaner Vehicle: I require a safe rental/loaner vehicle immediately, paid for by Hyundai, while my car is being inspected. Full Engine Replacement: I am demanding a full engine replacement as previously indicated by technicians should the light return. Expedited Review: I am extremely unsatisfied to be told again I have to wait "3-5 business days" for a safety-critical evaluation of a vehicle that has alre

The engine, specifically cylinder # 3, has had a catastrophic failure at 114,000 miles. Engine repair shops and engine experts have determined the only fix is a complete engine replacement. Cost estimates are $8500 for a new engine + labor estimated at $2000. Scrap value is estimated at $1000 - $1500 The dealer from whom we bought the car in late 2015 said it is out of warranty. This is unacceptable. Please, please issue a recall on the engine of this vehicle. The vehicle is available for inspection if requested. Failure was catastrophic Problem has been confirmed by engine experts The car is not drivable to a manufacturing facility The engine has not been inspected by police nor our insurance company There we no warning lamps or messages Symptoms include shuddering at initial acceleration beginning at 75,000 miles Dealer said there was no problem and recommended and performed a transmission fluid change

The horn on my 2025 Hyundai Tucson Limited failed without warning in mid January 2026 and no longer functions. This creates a serious safety risk because I was unable to warn another driver while they were merging into my lane on the highway. Without a functioning horn, I cannot alert other drivers to avoid potential collisions. The vehicle was inspected by Balise Hyundai in Springfield, MA, on January 23, 2026, and the dealership confirmed the horn requires replacement. However, they cannot cannot order the replacement part because it is unavailable, possibly due to a redesign or manufacturer change. Hyundai Consumer Affairs has acknowledged the defect and confirmed there is no timeline for repair. They are not allowing dealerships to order the old part and do not have a timeline on when the redesigned part will be available. Because the horn does not function, my Massachusetts State Inspection sticker is expired and cannot be renewed until the horn is repaired, making the vehicle illegal to operate. There were no warning lamps or prior symptoms before the failure. The vehicle is available for inspection upon request.

The horn in our 2025 Hyundai Tucson failed. We took the vehicle to two separate dealerships to get replaced, but were told the horns were out of stock with no ETA for parts. I followed up multiple times over several months with both dealerships, but got nowhere. This is a huge safety issue. How can Hyundai not correct this issue?

ENGINE
My 2018 Hyundai Tucson experienced sudden catastrophic engine failure when a connecting rod threw while driving. The engine burned through its oil and the vehicle became inoperable. Hyundai denied warranty coverage for this engine failure because I had not completed the 2021 KSDS (Knock Sensor Detection System) recall. I was never notified of this recall. The KSDS recall is a software update intended to detect engine knock. It does not prevent mechanical engine failure. Denying warranty coverage due to a software update that I was unaware of raises safety concerns, as engine failure can occur suddenly while driving and creates risk of crash or injury. This appears related to known engine issues in Hyundai vehicles. I am concerned this is a broader safety defect affecting other consumers.

Horn did not work. At about 67,000 miles on my vehicle my horn stopped working. I took it to the dealership to be replaced and paid for it. Then again at about 100,000 miles it stopped working. I took it back to the dealership and asked if there’s been any recalls they stated not at this time but there’s been a lot of people complaining about their horns and they told me to save my receipt receipts because I might be able to get reimbursed later. On two different occasions. I’ve been driving and had a car changing lanes into my lane and when I went to honk the horn to alert them, it didn’t work. Now I’m also concerned that I’ve got the same horn put on my vehicle for a third time and that I’m going to have to go back in and pay for a third one. I did reach out to Hyundai USA first and ask them to make this right but they stated they do not have an extended warranty for the 2023 vehicles even though they do have bills for 2020 through 2022. I can get copies of the receipts if they’re needed

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The adaptive cruise control reduces speed when the car's driver camera "senses" that driver is distracted when in fact, this occurs frequently within even a 30 minute drive: it senses "distracted driving" due to wearing sunglasses, short stature making in cab camera have difficulty seeing eyes of driver, etc. This is a frequent problem in my car and a frequent problem in driver forums. This is unsafe when it slows car without warning and is stressful. Upgrades needed for safety.
