2015 Hyundai Sonata: transmission slipping

Filed Feb 8, 2022 · Transmission · OH

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.

I purchased my 2015 sonata 12/04/2017. Almost immediately, my gear started to slip. At first had issues breaking, it seemed a bit delayed. I was advised by some family members that maybe the engine simply needed to be flushed. (early january) about 2 weeks later going up and down hills started becoming an issue. Due to my busy work schedule, I had to put off going to the shop. My car is necessary for my employment. The week before I was due to service (early february) my car stopped moving forward or backward after stopping at a local stop sign, I towed the car into the dealership and they have decided that the cause of these issues is a crack in my transmission. They have decided not to use my warranty to cover the damages because they believe that it was caused by a driver. They explained that the part that seems to be affected, is the only part of the undercarriage that isnt protected by the plastic cover piece. They said this damage could have happened unknowingly and easily. This has made my car extremely vulnerable to outside damage and has also brought the value of the car down extremely.

There are many problems with this car, steering is #1 at low speed is makes a popping noise, at speed is has dead spots, entire steering assembly could be moved. The transmission is rough and feels like it is hunting and stumbling between 1/2,2/3 shifts, downshifts 1 or 2 ranges at the slightest hill. Back up camera comes on and then goes black in the middle of backing up. Brakes feel like they are slipping if you are braking at low speed on a hill, as in parking. I have taken it back to the dealer 3 or 4 times, they are unable to fix the problems, though they did manage to fix the moving steering assembly the 2nd visit wile denying they did any work. I have attempted to get hyundai to buy this car back under the lemon law but they say nothing is wrong or it is not severe enough...I feel like I have to take a huge loss to trade it in on a dependable car or wait till something fails completely (hopefully not the steering) before they will listen to me.

I went to accelerate, by depressing the accelerator, and the engine revved high, but, the car did not accelerate and there didn't appear to be power at the wheels. It acted as if the transmission was slipping. I let off of the pedal and it downshifted and power to the wheels was restored. I repeated this process 3 times after and I could replicate it every time. Drove to the dealership and left it for service. They drove it the next day and couldn't replicate the issue. I have not been able to replicate the issue since that day either.
