There is an oil problem with this car - my engine light keeps going on, then it backfires, I brought to the dealership and $2,800 later, I still have the same problem. There is no leak that I can see, the oil just disappears. My mechanic said this is a known problem but Hyandai will not get back to me, I have tried several times with no interaction back

The vehicle is consuming oil because it’s burning it. The mechanic changes my oil and the same day the oil turns black. I have to constantly check the oil gauge and top up the oil when low. Unsure of the damage this might be doing to the motor.

UNKNOWN OR OTHER
My dad gave me his car a little bit ago, and I just learned there is a cap and sensor part in the engine that fills with oil which triggers the check engine light. I nearly got hit because I didn't know the car couldn't accelerate properly when this happens. My neighborhood exits onto the main road at an incline and my car wouldn't move faster than 10 mph while cars were coming behind me at 45. I was terrified. My dad told me had the same problem. He took it to the dealership to be repaired when it happened to him and they said it was fixed, so apparently it is a reoccurring problem.

ENGINE, FUEL/PROPULSION SYSTEM
I am reporting a serious safety concern involving my 2016 Hyundai Sonata Hybrid, which has experienced multiple hybrid system shutdowns while driving. This includes repeated complete power loss incident on I-90 beginning in June 2022, when my daughter was driving home after her hospital shift. The vehicle displayed a “Hybrid System Warning – Turn Off Engine” message and had to be pushed off the highway and towed. This was the first of several hybrid-related failures that culminated in a full engine replacement under warranty at 82,015 miles — and now, the same hybrid system warning has returned at 127,592 miles, well within Hyundai’s 150,000-mile hybrid warranty. Hyundai is currently denying coverage. I am requesting that NHTSA investigate repeated hybrid system faults and warranty denial patterns in Korean-manufactured Sonata Hybrids.

ENGINE

ENGINE
I am writing to formally request reconsideration of a denied warranty claim regarding my [XXX] son's 2016 Hyundai Sonata, which recently suffered complete engine failure and Hyundai has denied. The vehicle is equipped with the Theta II engine, which is widely known to be associated with engine failure risks and is covered under Hyundai’s extended warranty program. Despite this, my warranty claim was denied due to the fact that two recall-related services were not completed. I would like to respectfully challenge this decision for the following reasons: The engine failure is consistent with the known defects in the Theta II engine, which Hyundai has acknowledged through its extended warranty program and recall campaigns. I was not properly informed of the outstanding recalls or their impact on warranty eligibility. We purchased the vehicle in November 2024 and had not received any notifications of these recalls. Had I been made aware of these recalls I would have taken immediate action but again, I was not ever notified. The failure of the engine is unrelated to any owner negligence and should be covered regardless of recall status, especially under a defect-related extended warranty program. The failure has left my son without a functioning vehicle and facing a costly engine replacement for an issue Hyundai has accepted responsibility for in thousands of similar cases. He started working at [XXX] to begin saving for his first vehicle. He spent $8,000 of his own money and is now devastated by an issue outside of his control. I am requesting a full reconsideration of my claim and repair costs under the extended warranty program. Due to the Engine failure my sons car locked up and died while traveling with passengers. This was a terrifying safety event as my son was stuck in the driving lane with traffic until the car could be towed. Please let me know what additional information you need to review my case. Thank you, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

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.

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.

My car on the freeway started knocking. The check engine light came on. The car immediately caught fire. It is at the tow yard now. We just went through the oil consumption testing and the cleaning. I filed a report in November it failed for misfire and we paid to have the top rebuild. The car failed the oil consumption 1000 miles after the cleaning. We were told to continue to drive. We had 4 people in the car. I have the dash cam with the rod knock. The car has a check engine code. Hyundai needs to be held accountable.
