ENGINE
I have regular oil changes (every 3k mi) and every time I go get say there’s no or low oil. At the beginning of July my engine coil in column 3 failed and I had all four coils and spark plugs replaced. Since the replacement my engine is still consuming a quart of oil per week

ENGINE, FUEL/PROPULSION SYSTEM
I am submitting this formal safety complaint regarding my 2018 Hyundai Tucson. The vehicle has 101,900 miles and has been well maintained. Recently, it began experiencing severe performance issues, including difficulty accelerating and consuming oil at an abnormal rate. The dealership diagnosed the problem as a failed catalytic converter with an estimated repair cost of over $8,000. While Hyundai has an active recall on the engine for this model year, they have stated that my specific problem is not covered, despite the fact that the catalytic converter failure appears to be directly related to the engine defect. The oil consumption and acceleration issues raise serious safety concerns, as the vehicle can lose power unexpectedly while driving. I am a teacher, a parent, and have one child with special needs. I have no other form of transportation and am still making payments on a car I cannot safely drive. Hyundai’s refusal to address this issue as part of the known recall leaves me with an unsafe and inoperable vehicle through no fault of my own. I believe this matter warrants further investigation by the NHTSA, as it suggests that related component failures stemming from the defective engine are not being adequately addressed, leaving owners at financial and safety risk. I respectfully request that the NHTSA investigate whether Hyundai is failing to address a known defect’s full scope and to take appropriate action to ensure the safety and fair treatment of affected consumers. Thank you for your attention to this matter.

ENGINE
Vehicle is consuming oil at a rate of 2 quarts per 1000 miles which could lead to catastrophic engine failure at highway speed causing serious crash and loss of life. This is apparently a common defect with many Hyundia engines that the manufacturer is actively trying to deny warranty claims.

ENGINE, POWER TRAIN
This unresolved issue has created serious safety risks. On two separate occasions, my vehicle lost power while crossing the Leo Frigo Bridge in Green Bay—an extremely dangerous scenario for both my family and other drivers. Most recently, within just ~40 miles of picking up the vehicle from service, the issue recurred. The service department reported finding oil on the ignition coils—symptoms consistent with known and documented warranty concerns such as: Valve cover gasket leaks Spark plug tube seal failure High-pressure fuel pump gasket leaks The vehicle has been brought multiple times to a certified Hyundai dealership for recurring problems including power loss, poor engine performance, and excessive oil consumption. Despite these repeated service visits, the underlying issue has not been properly addressed. I have now been informed that I am responsible for diagnostic charges—even though the vehicle is covered under the TXXM Engine Warranty Extension / Powertrain Limited Warranty due to known oil consumption-related defects.

FORWARD COLLISION AVOIDANCE: WARNINGS, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Several times now the Forward Collision Safety has activated and the car came to an abrupt stop. The car in front of me was braking and I was lightly tapping the brake pedal when out of nowhere the car started shuttering and came to a complete stop. This definitely scared me and I was relieved that the car behind me did not rear end me. I was not going fast by any means and I did not slam on the brakes as there was no need to. The Forward Collision is not a safety feature. This is a real problem and now I am scared of this braking design. I now deactivate this feature every time I turn the car on because there is no way to permanently dismantle this. Hyundai needs a recall to correct this.

FORWARD COLLISION AVOIDANCE: WARNINGS
I was driving with my forward collision assistance (FCA) disabled via the cars setup menu. The dashboard had an indicator light on confirming the FCA was off. I was making a turn within a strip center parking lot and the car applied the brakes and the dashboard showed the “emergency braking” warning. As I was turning left into a lane with parked cars, a person was walking behind their car at least 1-2 car lengths in front of me on my right side. I’m sure this triggered the warning. 1) the situation did not call for applying the brakes. 2) the FCA was OFF! I have been disabling the FCA off each time I get in the car because of three other instances of unexpected and unnecessary full stop braking. See my previous report to NHTSA, same car.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I was driving my new 2025 Tucson on a 2400 mile trip. On the way back the entire dashboard went black and I got a big red notice. No signal. Could not see anything. No speedometer no nothing after while a black screen went away and I got the regular screen back but it had all of the fault lights lit up. This happened periodically through the whole trip. In addition, the heads up display worked periodically only. And I could not use the cruise control as it kept telling me that it couldn't see my eyes. Although I did not have any glasses on at the time. I feel very unsafe with this car. It is at the dealership waiting for new wiring harness but as I see in social media this has happened to many other people. I think this is something you should know about.

1. December 2024: Hyundai dealership diagnosed my transmission as defective (unable to shift properly) and recommended a full replacement. Despite this, they assured me the vehicle was "safe to drive" without disclosing risks. - Unedited dealer text: "The tech said he doesn’t think it will break down or leave you stranded, he just can’t get it to shift correctly." - No warnings were given about prolonged use, highway driving, or potential failure. 2. Post-Repair Damage: After relying on Hyundai’s advice, the transmission worsened, causing additional damage (e.g., radiator failure). 3. Recall Negligence: My VIN was wrongly excluded from Recall 16V-628 (transmission control issues), despite exhibiting identical symptoms. They didn't cover repairs, despite their technician confirming the defect. The safety impacts are as follows: - Sudden loss of power while driving (e.g., inability to accelerate or shift). - Increased crash risk due to erratic transmission behavior. - Hyundai’s failure to warn put me and other drivers in danger. I am requesting: - Investigate why my VIN was excluded from Recall 16V-628. - Force Hyundai to reimburse repairs and extend recall coverage. - Require Hyundai to issue clear safety warnings after faulty repairs. Attached is the following: - The radiator repair invoice. - Proof of text from Hyundai. - Proof of my Vin being excluded from recall. - Quote for my transmission repair.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
On two occasions, the dash lights kept blacking out, along with the Heads Up Display. On my way to the dealer for a maintenance appointment, all of the emergency lights came on and would not go away. After parking at the dealer service center, I told my service rep what happened, and when she restarted the vehicle, the lights were still on. I was immediately given a loaner. After making the repair, the mechanic asked to keep the vehicle to drive for a few days to make sure the problem didn't come back. I know these problems can reappear, even after they are fixed. I don't want to drive the car if the safety lights are all illuminated, but I also don't want to be stuck someplace without transportation.

ENGINE, FUEL/PROPULSION SYSTEM
I have been dealing with ongoing engine performance problems for over a year. My Tucson consumes oil at an abnormal rate, and I constantly have to refill it. There is also sluggish acceleration, and the Check Engine Light has stayed on despite multiple inspections and maintenance efforts. I’ve seen hundreds of complaints about this exact issue from other Hyundai owners. I also found that an NHTSA investigation is ongoing, yet Hyundai continues to deny responsibility, often blaming the issue on the owner. I believe this is a safety concern and a manufacturer defect that needs to be addressed before more drivers experience full engine failure. Please investigate this further and include my VIN in any future action or recall.

The reason of this complain is due to excessive oil consumption which now damaged my catalytic converter against Hyundai Motors America. The complained started 2021 where we noticed that the low oil engine light up after only 1500 miles from last oil change. We submitted the complained with dealer (Carlsbad and Escondido CA) and my car failed 3 consecutive oil consumption test and Hyundai performed an engine cleaning, claiming it was going to fix the problem. This happened when the vehicle was still under warranty. At the time they said that if this did not fix the problem, they were still going to fix the car since the issue happened under warranty. The engine cleaning DID NOT fixed the problem, my car no longer has warranty and my catalytic converter fails and makes the vehicle inoperable in highway (engine ceases to accelerate) . We submitted a complain with Hyundai corporate and they denied fixing our car since the vehicle was no longer under warranty. I would like to ask for them to fix the engine and catalytic converter make the car operable again.

My HUD was going off and on, especially on bumpier roads. This could happen several times on a drive. At least once, when the HUD went out, the dash lit up like a Christmas tree (all the warning lights came on), and a couple times it went totally black. I took it to the dealer and they diagnosed a bad head unit, and am awaiting parts.
