My Sonata has been burning through oil. I have to add a quart about every 1000 miles or less. I am getting my oil changed frequently due to this problem. I was told at my mechanic's that this is a common issue with 2013 Sonata's. I don't know if there is anything else wrong but my engines lights come on and the car is having issues getting to speed limits on highways as it is very sluggish.

Sensors lights would indicate an issue and would disappear sometimes without any reason (mainly Check Engine and Tire Pressure Sensors). Indicators would trigger the opposite direction (indicate right and the left indicator would turn on). Burning more fuel than expected. Primary fuel pump stopped working resulting in car stopping in the middle of the road.

My 2016 Hyundai Sonata (sport) with the 2.4 GDI theta II seized on me WHILE DRIVING down the interstate on April 14, 2022, no engine light, no warnings, nothing. It was extremely dangerous & also very scary. The car did this at 135,000 miles. I had my Sonata towed to a Hyundai service center after this happened. They did a diagnosis, confirming it needs an engine replacement due to connecting rod bearing failure. They sent in a Prior Approval request to Hyundai and Hyundai DENIED the engine replacement, due to not having Campaign 953 (knock sensor detection software) completed prior to bearing failure. (EVEN WITH having this sensor update done, it would NOT prevent the motor from failing, just tell you when it happened.) That software update wasn't going to save my engine, it was only designed so Hyundai had a LOOPHOLE to deny as many engine replacements as possible and not process these warranties the right and ethical way. They put a faulty engine in my car and it seized and failed at NO fault of my own. But the fault of Hyundai for allowing these vehicles with bad engines to be sold to innocent people who had no idea these engines were made to fail. Hyundai knew the Theta 2 engines were going to fail and STILL allowed these vehicles to be sold and NOT RECALLED knowing the dangers. That is wrong and unethical. It is crucial that these vehicles be RECALLED. Any engine liable to seize while driving 70+ mph on the interstate warrants a RECALL. They needed to be recalled long ago, but instead Hyundai created a loophole by issuing Campaign 953 (knock sensor detection software). It never fixed these dangerous, faulty engines. It's only put more people at risk by not issuing a RECALL on all THETA 2 engines.

- #11509128February 25, 2023ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION:SUMP/TANK:DRAIN PLUG
Engine oil plug backed out while driving causing loss of all engine oil in the mountains. Drive time was one hour when oil lamp turned on as we reached our destination. Oil check stick had no oil on it and the whole undercarriage and rear of the car was covered in engine oil. Made an attempt to refill oil and plug fell all the way out and poured the new oil onto the ground. The oil plug is not visible or accessible due to a plastic cover on the underside of the car. The vehicle was towed to Elk Grove Hyundai dealership for service since they were the last hands on the car for regular maintenance. It was confirmed by the dealership the oil plug backed out on it's own. My family's safety was compromised as we were driving at night in steep mountains during high traffic time. There would be nowhere to go if the engine ceased and would cause an accident on HWY 50 in California. Also a full six quarts of oil was leaking on the back roads, highway, and residential roads, and eventually in a high school parking lot was were the bulk of the oil was spilled. The is an environmental hazard at public school Eldorado High School.

This car engine has failed on multiple occasions. About 12 months ago, I observed a great loss of coolant. The car would frequently overheat even when I added coolant. Eventually, I was able to have the engine replaced at the dealership where I purchased the car, but this was right at the end of the vehicle's warranty. Even with a new engine installed, I still lose coolant all the time. It does not appear to leak anywhere, but the reservoir is consistently empty.

- #11508517February 22, 2023FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The forward collision warning, automatic emergency braking and adaptive cruise control failed as the first 2 activated when there were no oncoming collisions in front of me and the nearest cars around me were 1/4 of a mile away. The cruise control failed as it turned back on after the vehicle veered off the highway and into the rest stop. My safety and the safety of a lot of other people in the rest stop were put at risk because the system malfunction and tripped when no other cars were present that would have led to a collision. The vehicle led me off the highway into the rest stop where others could have been fatally hurt. I ended up with a shattered left foot that required a major reconstructive surgery to mend but the break will affect me the rest of my life, with more problems developing later on in life as well. No one inspected the vehicle or listened to what I had to say. No investigations were launched by insurance, the manufacturer or the police. If anything, insurance and the manufacturer seemed like they were in a hurry to dispose of the vehicle, urging me to release vehicle where it was sent to after the crash to one of insurance centers. The collision warning light came on and the vehicle responded by hard braking and veering to the right, then the cruise control turned back on and accelerated into the rest stop, first bouncing up the curb and onto the dirt, hitting a sign on the passenger side then bouncing off a tree on the driver side and finally T-boned a parked boat on a trailer head on. The vehicle was a total loss

The contact's girlfriend owns a 2017 Hyundai Sonata. The contact stated that while his girlfriend was driving at an undisclosed speed, the vehicle lost motive power with the check engine warning light illuminated. The vehicle was towed to the girlfriend's residence. The dealer was made aware of the failure and informed the contact that he needed to pay out of pocket for the diagnostic. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and confirmed that the VIN was included in Service Campaign Number: 953 (ECM & Cluster Update - Engine Monitoring Logic Product Improvement). The failure mileage was approximately 64,500.

I was driving on the freeway, at the speed limit, cruising along. Then all of a sudden, my vehicle starts to decelerate from 65 MPH and I push the gas, thinking I must have let up too much on the pedal. However, that only causes the RPM to drastically rise with NO change in my speed. I thankfully managed to maneuver from the far left lane to the freeway shoulder on the far right. The whole time, my speed was around 40 MPH and dropping drastically. Trying to safely navigate a slowing vehicle on a 65+ Texas freeway is an adrenaline-rush that I wouldn’t wish on anybody. I was severely panicking. I was almost hit by several vehicles in my maneuvering. I could have died last night. Once on the shoulder, I tried to start my car. I thought it may be a battery issue, but it turned on. It didn't start, though. The lights came on, as did all of the typical system/dash lights that usually indicate when a car’s engine hasn’t “turned over.” I used Bluelink to call for roadside assistance (since I’m only a little over 2 months into ownership) and waited. I was escorted off of the freeway to safety — thanks to a 3-car police escort AND free city tow trucks — and eventually picked up by Hyundai-serviced AAA. The latter then towed my vehicle to the dealership where I bought my Sonata. My car is currently being checked/inspected by my dealer (North Freeway Hyundai) and I only have gotten the following notice from Bluelink: "A possible condition with your Engine Control System has been detected with your 2023 SONATA on 02/22/2023 at 07:23 am CST. A full system check is recommended to be done soon." I checked and there are no open recalls (currently). Even more concerning, my car recently underwent complimentary maintenance, including an oil change, through my dealer (on February 13, 2023 - I have the receipt), was good on gas, and had no warning lights displaying. Until it stopped running — the time I tried to start it on the side of the road, the dash showed an “engine” light.

Well below the 5000-mile mark for an oil change, multiple times between multiple oil changes my oil light would come on. I would be at a stop light and the oil light would come on as soon as I start going again. Checked the oil when I got home and there was barely any oil on the stick. Found hundreds if not thousands of complaints about the engine burning oil very fast in multiple Hyundai's and Kia's for almost a 10-year span. This has yet to be recalled by Hyundai, this is a very dangerous situation that if it continues going unnoticed, could cause death or serious injury. It is a known issue at Hyundai dealerships, and they will fix it if it's still under the 100,000-mile warranty, but only if you bring it up to them. Hyundai/Kia has yet to fix the problem or do a recall that has been across multiple models for 10 years.

The contact owns a 2016 Hyundai Sonata Hybrid. The contact stated that while his wife was driving at a slow speed out of the driveway, she heard a knocking sound coming from under the hood. The check engine warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed that the engine needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that after the vehicle was retrieved from the dealer, the check engine warning light illuminated after 300 miles. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 163,000.

While driving home on my way from work, the car started to stall on the highway and slow down. A knocking sound began to come from under the hood and would speed up when I stepped on the gas. From the sound of it, it seemed like the engine was malfunctioning and yes it is available for inspection. My safety was put at risk because if the car was to stop in the middle of the highway, not only am I at risk of being in an accident but other people as well as we are all driving at high speeds. This problem has not yet been confirmed by a dealer but when I took it to a mechanic, I was told that it was a rod that's what's causing this, and though there are no recalls on this specific model (2016 Sonata Limited) there are other recalls on the hybrid model for a rod in the engine wearing out prematurely which is very similar to what is happening with my car. A check engine light turned on a few minutes prior to the incident but then turned off.

I was driving my vehicle and a warning light indicating hybrid system charging failure warning. The vehicle had intermittent power problems and would not move appropriately in relation to the pushing the gas pedal. It would not go then would jerk forward. I was finally able to pull over to the side of the road safely. I turned my car off and when turned back on the error message failed. This happened on two other occasions. Later there was a whining noise when shifting into second gear. I took in for service and the hyundai dealership told me the transmission needed to be replaced. My safety and others were at risk due to loss of ability to drive the vehicle appropriately due to loss of power.
