I had my engine replaced under the Theta Engine lawsuit and I was due for the 9C2 service campaign and it was installed...ever since I picked up my car it shifts weird between 1st and 2nd. I brought it back to a different Hyundai dealer as the warranty work was done at another location and they recommended a transmission flush and relearn. They can feel it slipping and the other dealership noted no problems, which leads me to believe it was because of the service campaign. I also called corporate and the customer service rep had heard of this before as well as a bunch of forums online.

What owners say
After completion of Hyundai Service Campaign 9C2, my 2016 Hyundai Sonata SE is very difficult to drive at low RPMs. Cold start its sluggish and jerks and driving uphill feels like transmission slipping but is not. An additional update to the ECM needs to be conducted ASAP.
The contact owns a 2011 Hyundai Sonata. The contact stated while his wife was driving 10-15 MPH, the vehicle jolted, and the transmission slipped into 1st and 2nd gear. There was no warning light illuminated. The contact stated that his wife veered to the side of the road, shifted into neutral(N), and then shifted back into drive(D), and the vehicle responded as needed. The dealer was notified of the failure and advised the contact to tow the vehicle to their location because the vehicle was unsafe to drive. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,000.
The vehicle's transmission seems to be slipping or something. As you begin to come to a stop, the vehicle bogs down and you can not accelerate. There is a long hesitation and then suddenly it kicks in and jars the car. This happens on a daily basis. The vehicle is also burning through oil at an unprecedented rate.
The contact owned a 2011 Hyundai Sonata The contact stated that while driving, the accelerator pedal locked up and the transmission was slipping. Smoke was detected and fire emerging from the engine. The check engine warning indicator light was illuminated. There were no reported injuries. A Police report was filed. The fire department extinguished the fire. The vehicle was towed to an unknown location. The local dealer was not contacted. The vehicle was not diagnosed or repaired The manufacturer was not notified of the failure. The insurance company deemed the vehicle a total loss. The failure mileage was 187,479. The VIN was not available.
Entered a freeway on-ramp, the engine started to make a slapping noise. I thought it was the fan belt slipping. We began to lose acceleration, had a burning smell We pulled off and had the vehicle towed. Subsequently we discovered that the issue was exactly that which appeared in a published recall notice: Symptoms of the problem can include abnormal knocking noises from the engine; reduced power or hesitation; illumination of the “check engine” light or the engine oil-pressure warning light; or a burning smell, oil leaks, or smoke. In discussing with Hyundai, it was stated that my VIN does not meet a full reimbursement due to the VIN not being included. How is that possible, when the symptoms match the year, Make, model. https://driving.ca/auto-news/news/hyundai-recalls-almost-129000-cars-in-u-s-for-possible-premature-engine-wear
My 2013 hyundai sonata issues: 1. My horn & left side of my steering wheel buttons doesn't work. I was told it could be related to fuses or clockspring replacement. Trip a/b and other buttons doesn't work , I've been driving for over a year without a horn because this isn't a recall. This is a huge safety issue. 2. My gears are start to slip in the transmission. I was told it could be two things it's either the transmission or speed quality censor. These cars were made either very fast or very poorly or both and this is another safety issue. 3. Electrical issues. I have to manually adjust by back light/break lights daily because they never stay in place. The whole wiring for this vehicle is horrible. Sometimes while driving the car suddenly starts to slow down. Every once in a while my radio is on but doesn't light up. Light bulbs are melting into light sockets. Electrical issues that are a safety issue for many with these model cars. Eitherway none of these issues were a problem until after hyundai performed all of the recalls on my vehicle. They charge $200 for a diagnostic that I'm not willing to pay , theses issues came from the makers of this vehicle, these should also be added to the recall list. I'm sure if you look around online there's others who's dealing with these issue from 2013 - 2021 today. I don't think it's fair that I purchased a vehicle and have to come out of pocket for all of these repairs that should have been repaired from the beginning. These are safety issues that should be taken more serious. I've almost got into multiple accidents because my horn doesn't work. My vehicle worked fined before all of the previous recall repairs.my transmission slipping left me in the middle of nowhere until my car started functioning properly to get home.the electrical on this car is costing me money non stop. Hyundai needs to fix this! 2.
My transmission appears to be slipping. Really scared to drive it far but can't afford to replace the transmission.
Every time I stop and start to go again in first and second gear it feels like my car is slipping and not wanting to catch the gear seems to me like it's going to stall in the middle of the road one day
The car slips out of gear with changing the shifter from park to reverse. The selector will be in reverse and as the car is moving it slips out and goes neutral
