SERVICE BRAKES, ELECTRICAL SYSTEM
the car has abruptly applied braking while driving. I took the car to get checked after that and i was told that there was nothing wrong except that the pads will need to be change sooner than later. I mechanic did tell me that it could be a safety issue because it was an uncontrollable. I than took the car to the Hyundai dealer for them to diagnose the car. They proposed that i change everything, including the brake pedal, which to me, sounded very fishy. One week ago, while driving, the car suddenly jammed on the brakes again. This particular time, it was also emitting smoke, either from the front or the bottom.

FUEL/PROPULSION SYSTEM
My car stalled while driving through an intersection and nearly caused a T-Bone collision. The car would not start afterwards and towed to dealership. The car currently has 32000k miles on it. The inspection report stated leaking fuel injectors causing misfires. This was covered by warranty. The parts are currently backordered with no eta on possible repair indicating it might be a widespread issue. There were no warnings or lights prior to incident. The car had just been serviced at 30k miles by the dealership with no indication of possible failure given to me by maintenance department. The dealership is out of loan vehicles and I’ve been without a vehicle for 6 days now causing work and personal issues.

So my car started to stall when I started it an when I started goin down the road like it wanted to die. Then I started to smell gas very strong so had a code tester put to my car an i have 6 permanent codes. An not only that im smelling oil strong an noticing big oil spots under my car. So I look under the hood an behind the turbo I see oil behind an underneath the turbo. I definitely didnt feel safe driving but now its not even drivable. I purchased it couple months ago from an individual an i cant belive the amount of problems this car has. Im a single mom an trying to support my family an its hard to now with a non running car. I've put quite a few parts hoping it would fix some of the problems an nothing has. I absolutely love the car an very beautiful but unfortunately to many problems with it. Eninge, gas leaks, timing

The left rear door won't open from the inside or from outside. The door just suddenly stopped working without any warning or without any damage to the door, or to the key FOB. I use it to transport an elderly person or sometimes my grand kids, it is dangerous especially if someone has to exit the car immediately.

ELECTRICAL SYSTEM, POWER TRAIN, VEHICLE SPEED CONTROL
I have gone 3 times to dealer because speedometer was off. They confirmed that the speedometer was off but they couldn't do anything about it. They told me that for this car, there is no VSS and the speedometer gets the speed from the navigation system. The navigation system is obviously glitching which is causing this. I am not the only person experiencing this. This has to be taken care of and taken seriously

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
The gear shifter design on this Hyundai model is dangerously counterintuitive compared to industry norms. It nearly caused me to drive off a cliff. I encountered a serious safety issue with the gear selector design. In most vehicles — including Mercedes, GM, and even pickup trucks — pushing the gear selector down engages forward drive, and up engages reverse or park. Hyundai has reversed this logic. In a rushed moment, I instinctively pushed the shifter down expecting to go forward (as in most cars), but the Hyundai was in reverse. I stepped on the gas and nearly backed off a cliff. This design is not just unfamiliar — it's opposite of established standards. Drivers with muscle memory from other vehicles like ANY pickup truck, MB, or GM EV are at real risk of making fatal errors. I strongly urge NHTSA to investigate whether this shifter design meets safety and human factors standards. At a minimum, Hyundai should issue a UI/UX recall to standardize shift direction or implement safeguards to prevent this kind of mistake.

ENGINE, POWER TRAIN
I am filing this complaint regarding a serious engine issue with my 2006 Hyundai Sonata equipped with a 2.4L GDI engine. My vehicle experienced [engine knocking, stalling, and then seized up indicating complete Engine failure] without warning, posing a potential safety hazard while driving. The issue appears to be identical to the known manufacturing defects that Hyundai has acknowledged in its recall of 2013–2014 Sonata models with the same engine Class Type. Although my vehicle is not currently included in the official recall “ SONATA ENGINE RECALL CAMPAIGN it contains the Theta II MPI Engine which constitutes and Further solidifies proof of the ongoing Manufacturing Defects of Theta Model Engine design and exhibits the same symptoms of sudden engine failure. This raises concerns that the defect may affect a broader range of model years than Hyundai has acknowledged. I urge NHTSA to investigate this issue and determine whether the scope of the current recall should be expanded to include earlier model years such as 2006. The defect creates a significant safety risk to drivers and passengers, and Hyundai should be held accountable for all affected vehicles—not just those produced within a narrow window.

ENGINE
While driving my 2016 Hyundai Sonata Hybrid SE (89,000 miles), a “Check Hybrid System” warning appeared on the dashboard, followed by a sudden loss of power. Shortly after, the engine began knocking loudly. A local mechanic scanned the codes and saw engine misfire and hybrid system faults. After clearing the codes, the engine ran worse and the knocking increased significantly. I had to tow the car over 700 miles from Whitehorse, Yukon, to the Anchorage Hyundai dealership in Alaska, which cost me over $5,000. The dealership said they hear engine knocking but refuse further diagnosis unless Hyundai initiates a goodwill assistance case. My car has a rebuilt title, but this issue appears to be similar to other known failures and recalls, such as Campaign 198 / NHTSA 20V746000. It is a serious safety issue — I was stranded in the middle of a remote highway. This appears to be a major defect, and Hyundai needs to investigate and support affected customers.

Burns oil fast. 900 miles from an oil change the car oil stick was empty. There are no signs of oil leaking. Every 1000 miles you have to place oil back into it. I’m not the only one complains of this issue. I was reading on Reddit and it’s thousands of people having the same issue.

I was driving my yesterday morning like normal, about 15mph getting off of a freeway offramp, when all of the sudden I heard a strange brief noise come from the inside of the car. I couldn't figure it out so I drove home. Went inside for about 20 minutes, went back outside to leave again and I noticed my panoramic sunroof had shattered/exploded from the inside outward. I had it towed to my local dealer in hopes warranty would cove, but I was told it wouldn't. I have to use aftermarket glass with my insurance company to replace it due to Geico not covering OEM glass.

STEERING
Steering sticks and releases under pressure at 60/65+ mph on interstate. Very difficult to keep vehicle in lane consistently. Constantly correcting both right & left to maintain straight line is extremely fatiguing especially on long trips. Safe driving at highway speeds is compromised and presents safety concerns for occupants as well as motorists nearby in addition to the apprehension it creates wondering if you're able to correct the steering drift before having an accident. There aren't any dashboard warning indicators when this happens Reported to dealer in central Florida on March 22, 2024 and dealer ordered parts Ref TSB 23-ST-003H. Hyundai Extended warranty TXXO. Factory has sent some parts to dealer twice that I know of and each time vehicle has been taken to dealer I've been told they were not what was needed. On most recent appointment of 12/19/24 I was told the needed parts were unattainable from Hyundai. On 3/20/2025 the dealer has offered to put in some of the parts they have as a possible solution but repair has not been scheduled. Dealer said they had another vehicle that took over a year to repair. This has been 14 months. We're only using this vehicle at slow speeds locally, anticipating complete failure, as we don't trust it for highway use.

2017 Hyundai Sonata having severe oil consumption issue. Having to top off with a quart of oil every 500 miles. Was purchased last June and has been a nightmare since. We contacted Hyundai consumer affairs and they opened a case and made an appointment for us to go to a local Hyundai dealer. The dealership told us we didn’t qualify for oil consumption test be cause we are second owners and the vehicle had 62,000 miles on it. We did purchase an extended warranty when we bought the car but they won’t cover oil issue. Local mechanic won’t touch it and refers us to Hyundai dealer. Just getting so frustrated and worried about car safety and engine damage. I read on another sit that Hyundai issued an oil consumption recall in 2025 but our vehicle is not listed. Please help us.
