Car engine is loosing/burning oil at a high rate. This could be best described as an oil ring problem that is included in other kona models but not my specific vin series

SERVICE BRAKES
Mushy brake pedal after 1000 miles This just started yesterday, seemingly out of nowhere. When I push the brake pedal it's mushier than it used to be. If I push hard, I get more resistance at first but then it slowly sinks toward the floor as a I continue to press. If I push softer then it just sinks toward the floor. I still have plenty of stopping power. If I push the pedal repeatedly then it builds up more resistance ("pump the brakes") but then the resistance calms down and it becomes mushy again.

I was driving when I heard a rattle below the car. About a mile later, my engine died. Turns out the oil plug fell out causing irreparable damage to my engine. Was fortunate to be able to coast down the bottom side of the bridge I was on to a safe spot off to the side.

ENGINE
Car is losing power. Car is stopping in the middle of the road. Car was towed to my Personal mechanic on June 21,2025 who has ran a diagnostic on vehicle & vehicle is throwing out an Engine Failure Code. Check Engine light is blinking ; car is making odd "knocking type" noises. First appeared June 20, 2025. Car is not safe to drive due to losing power. Vehicle is now being towed to the dealership (after multiple calls) and the loss of power is concerning/dangerous if vehicle looses power with traffic around. I feel I won't be able to get the vehicle and myself off the road safely before an accident/injury/fatality occurs. I will upload a copy of the diagnostic report

POWER TRAIN
Multiple people I know with 2024 Hyundai Kona AWD cars are having the same problem around 10k or so miles. The AWD is locking up. Car feels like rear wheels are slipping when turning and accelerating out of a full or partial stop. This is a widespread problem on this model and I am very surprised it is not a recall yet. Many drivers are having coupler or entire rear differential replaced on their cars-some less than 1 year old, or about 1 year old.

UNKNOWN OR OTHER
I purchased a 2022 Hyundai Kona brand new, and since day one it has had serious performance issues — specifically, harsh jolting during acceleration and occasional stalling. These symptoms are dangerous, especially when driving in traffic, merging, or crossing intersections. I discovered that a recall existed prior to my purchase, but it was not performed until after nearly two service visits — even though I had already reported these symptoms. I was never informed of the recall by the dealership before those visits. After the recall was eventually performed, the issues continued, and the dealership began doing software resets during service visits. However, these resets have not resolved the problem, and the symptoms return shortly after. The dealership claims there’s nothing wrong and refuses to escalate the issue. I have contacted Hyundai Consumer Affairs and am working with a national case manager, but there is still no resolution. I do not feel safe driving this vehicle. I believe this may be related to a defect in the transmission control system, electronic throttle, or dual-clutch transmission. I’m requesting that NHTSA investigate this as a safety-related defect, as it has persisted since purchase and affects both the safety and drivability of the vehicle.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
1. Component or System Failed or Malfunctioned: The primary component that has consistently failed or malfunctioned is the air conditioning (AC) system. The AC unit does not adequately cool the vehicle's cabin, especially in hot weather. The vehicle is available for inspection upon request; it has been previously inspected by authorized Hyundai dealerships. 2. How Safety was Put at Risk: The malfunctioning AC unit poses a significant health and safety risk, particularly due to the presence of a [XXX] infant who frequently rides in the vehicle. Driving in a hot car without effective cooling can lead to heat-related distress for a young child. There is also a concern that this persistent issue may indicate a broader manufacturing defect, potentially warranting a safety recall. 3. Problem Reproduced or Confirmed by Dealer/Service Center: Yes, the problem has been repeatedly reproduced and confirmed by an authorized Hyundai dealership. Paramus Hyundai has examined this specific AC issue on four separate occasions during the last summer, and a fifth visit is now scheduled/imminent. Despite these multiple service attempts, the issue remains unresolved. 4. Inspection by Manufacturer, Police, Insurance, or Others: The vehicle and its AC component have been inspected multiple times by an authorized Hyundai dealer (Paramus Hyundai). The manufacturer, Hyundai Motor America, is aware of this ongoing issue, as evidenced by two formal customer service cases: an older case (Case Number: [XXX]) handled by Customer Service Specialist Raghad, and a more recent, open case (Case Number: [XXX]) handled by Customer Service Specialist Simran. The repeated advice given for the new case is the same as previous attempts, indicating a lack of definitive resolution despite manufacturer involvement through their customer service channels. 5. Warning Lamps, Messages, or Other Symptoms: No specific warning lamps or messages have appeared on the vehicle's dashboard related to the INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

ENGINE
This vehicle was sold to me advertised as a certified pre-owned by Somersworth Hyundai in New Hampshire. They have since shut down and I now see that they have a long history of bad reviews and scamming. When I had my first issue with this car, I brought it in thinking that it was covered by a certified pre-owned situation only to find out that it was not. I had a rare, bizarre, and expensive transfer case replacement done and was forced to pay out of pocket. Now, my check engine light has been flashing for about a month. It also started having a slight stutter or shudder in low speed acceleration. It hesitates or feels like I let off the gas for a split second even though I didn't. This happens everyday. I had the spark plugs replaced and that did not turn the flashing check engine light off. The service shop that installed the new spark plugs printed out an nhtsa recall bulletin on my vehicle for piston oil rings that may not have been properly heat treated which could result in engine damage. Consequences being damaged engines may stall and increase the risk of a crash. As well as oil leaks may leak on to hot exhaust components increasing the risk of a fire. Hyundai dealership and Hyundai corporate. Both say there are no open recalls on my exact vehicle. It is not included in this recall. I need the diagnostic process including knock test performed on this vehicle.

ENGINE, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
My wife was pulling into a parking place at Home Depot when the car suddenly accelerated, jumped the curb & hit a tree on the sidewalk. It did significant damage to the front bumper of the car but the airbags did not deploy & my wife was not hurt. I am guessing that it will be several thousand dollars to repair.

AIR BAGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
My wife's car t-boned another vehicle, but the air bags didn't deploy. Luckily, she wasn't hurt badly, but the vehicle was deemed a total loss, so you can imagine the force of the collision. The forward collision warning and automatic emergency braking didn't activate either. I reported it to Hyundai. They sent an inspector to examine the vehicle, and I also showed them photos and a copy of the police report, but they claim that my car was hit on the side, and the pre collision system doesn't detect imminent side impact. That's completely outrageous. I don't know what their inspector wrote in their report, but the photos and police report are irrefutable proof that my wife had a frontal collision with the side of another vehicle. Hyundai kept denying it because they didn't want to help financially. I attached a copy of their determination letters (the second one was after I submitted a copy of the police report to prove that my wife's car is the one that hit the other vehicle, but Hyundai refused to see it as it happened). This is a link to see the interior and exterior photos of the vehicle: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORWARD COLLISION AVOIDANCE: WARNINGS, UNKNOWN OR OTHER
There has been a continuous popping noise on the right side of the vehicle near the tire like it’s an axle or something with the suspension. It has been checked and I was told it was normal. The horn will stop working along with the radio and other components in the car. The forward front accident component will say I’ve been in an accident when I have not even been near a vehicle. This has happened on several occasions. I don’t have all specific dates.

Radiator is failing between 60k and 70k miles with no check engine lights. Leaking an entire reservoir of coolant within a 24hr time period. Even when the temperature gage went above the middle mark and to the 3/4 mark the check engine light never came on.
