POWER TRAIN, ENGINE, VEHICLE SPEED CONTROL
Sonata started having problems with less than 50,000 total miles. The accelerator is flawed and the vehicle cannot keep speed when traveling uphill or get to speed efficiently. The vehicle jerks for a few seconds when pressing the gas and the engine revs but the vehicle does not accelerate like it should. This has almost caused me to have accidents multiple times when pulling out into traffic. The check engine light came on when this started occurring and has been on ever since. I'm having the hyundai dealership take a look at the vehicle and see if there is anything that can be done.

ENGINE
The engine is burning over 5 quarts of oil between 600 and 1000 miles. The engine is the 2.4 litre and it is doing the same as the 2014 and previous model. It is also known that the 2016 has the same issue. Hyundai refuses to replace the motor or cover any cost. They are saying that the car is out of warranty when it has been in the shop for oil consumption pre-mileage but they said it was normal to be a quart or 2 low. Now the motor will be empty by 600 to 1000 miles. The dealers wants to put chemicals in the motor at a cost of 200 plus with now promise of resolving the issue. In addition it has been proven that these quick fixes are catastrophic and will cost more than an engine maybe a life in traffic.

TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS, TIRES:TREAD/BELT, TIRES:SIDEWALL
215/55 R 17 My right rear tire has been losing air for at least 6 months. My tire pressure light is constantly on. I had my tire inspected and was told all 4 tires are compromised. The mechanic told me that my tires were wavy??? and that the tread inside my tires were damaged and I needed to replace all 4 tires. He also said my car would not pass inspection because of this defect in the tires. I feel my safety is at risk because of the inconsistent pressure that the tires may blow at any time.

ENGINE
Hyundai reprogramed their Theta engines to prevent an ongoing problem related to Theta engines not receiving oil to the crankshaft and connecting rod bearings. The software modification was done by an unknown software house. When I got the first notice, I asked both the local dealer, and the official Hyundai site if this software would cut power, potentially at the wrong time, like going up an entrance ramp. I got no response and I found out why. I tried entering a highway where traffic was at 75 mph. When I got onto the ramp the car was running fine. Suddenly the power just went away. I had the gas pedal all the way to the floor and watched the tachometer and speedometer go down rather than up. I pulled off at the next exit and switched the programming on my transmission to normal from econ mode. Up the ramp I went, and car started slowing down. Tried one more time using the sport mode and the power went away. I'm afraid to try and run on a freeway at rush our because of the lack of power. I think the needs to be a review of the software and see if changes can be made.

ENGINE
During weekend road trip, on the way back, engine has developed knocking noise, unusual vibrations, and loss of power. Car was able to make it home at low speeds with minimal acceleration. Oil check revealed that all of oil was burned up over a few days, as the oil check before the weekend trip showed full levels. Dealer would not even accept looking at the car for over a month, before their first available appointment. Independent mechanic confirmed engine knocking, burned up oil. They recommended engine replacement, but were not able to complete the job as the company would not make replacement parts available to them. Dealer has finally accepted car, also confirmed knocking noise and burned up oil. It would take another month for dealer to produce a repair quote -- $14,000 for engine replacement and additional 2 months of wait time for some parts to arrive -- much higher than what I understand it typically costs for a full engine replacement, but the dealer is left as the only option to charge however much they want, as independent services are blocked from acquiring needed parts. 87,000 mi in just over 6 years of use. No warning lights on the dash. No OBD status codes. All together this would add up to at least 5 months of inoperable car, and what looks to be a very inflated repair bill. Dealer is recommending a purchase of a new car from them instead.

ENGINE
Vehicle info: 2015 Sonata Se. 97450 Mileage. As with most all complaints with this engine, it is deteriorating slowly as the knock sensor code P1326 has sensed a knock. A private mechanic has verified that a rod bearing is either bent or broken and knocking against the engine. This is after two Hyundai dealers have denied even inspecting my vehicle. Due to the title status of my vehicle (rebuilt title) Hyundai dealers (King Hyundai in Deerfield Beach, FL and Coconut Creek Hyundai in Coconut Creek, FL) are denying repairs because the engine has no active campaigns or recalls on the engine even though Hyundai Motors of America has extended the warranty to a lifetime duration for this exact issue. This is a huge liability situation as these engines are known to catch fire for this very issue and Hyundai/Kia has been fined $140 Million for not acting sooner on this matter. These vehicles have been known to catch fire inside the dealership service center while going through diagnostic testing by certified mechanics. I have had the Campaign 953 serviced in 2018, which was a software update to alert owners when the engine is already failing (sensing a bearing rod broken). This campaign did not address the faulty engine but only alert you. Hyundai Motor America has told me that a Hyundai dealership should not deny me warranty coverage however every dealership in Palm Beach and Broward counties are denying my service order approval. Service managers refuse to send in a pre-authorization to Hyundai Motor America despite corporates approval of this warranty coverage therefore nobody wants to take responsibility nor liability for a known safety defect in Hyundai engines.

EXTERIOR LIGHTING
When the headlights are set to automatic and driving at night, the headlights and daytime running lights will spontaneously turn off when signaling a turn. This is an intermittent problem.The dash indicator still shows that the headlights are on but they are off and it has nearly caused an accident. When the selector is set to “on” the issue has not yet happened. Dealership stated that it would be hard to recreate problem.

LANE DEPARTURE: BLIND SPOT DETECTION, UNKNOWN OR OTHER
The abs and traction lights are illuminated on dash with check bsd system warning on dashboard as well. Seems to be common problem with this car. With these lights on the abs system I disabled. Was told it was speed censor and then it was the bsd sensor in bumper. They told me it was in an accident I should file claim with insurance. Sounds like they don't want to repair something faulty . No abs working could mean crash

ENGINE, ELECTRICAL SYSTEM
Out of the blue, I heard a very loud knocking noise coming from my engine. I was driving my children to school and as I hit the gas pedal the less power my car had. Not only would it not accelerate much but even the lights would dim. I am now paying over $400 a month for a car that I can not drive and walking where I need to go. My vin number does not qualify me for the engine recall Hyundai has, even though my car is the right year, make and model, engine size and problem that the recall is for. Awesome right?
