2017 Hyundai Santa Fe: shudder or vibration when accelerating

Filed Aug 28, 2026 · Transmission · CO

Known as an issue with Hyundai, but unresponsive to correct because no diagnostic code is sent. Transmission will shift extremely hard from 1st to 2nd gear randomly. In keeping track of the mileage, this appears to happen every 200 miles or so. Also, it faild to upshift correctly, making the entire car shudder. Also, at times it will not go into reverse gear. On one occasion, after finally doing so, it slammed so hard into reverse I almost collided with the car behind me.

My vehicle experienced catastrophic engine failure while driving on the freeway. It had just over 100k miles. I heard a repetitive clicking sound when pressing on the accelerator. After 2 minutes, the car shuddered and black smoke filled the cabin. When I pulled over, oil was s pouring onto the road. The car was serviced 2 weeks prior including oil change by a certified mechanic with no problems identified. I never had a check engine light. I initially had the vehicle towed to my local mechanic who found 3 ruptured holes in the bottom of the engine block. I was told that it looked like "rod failure". When I notified Hyundai corp, I was told that the vehicle was no longer under warranty due to it being purchased pre-owned and because I had surpassed 100k miles. They told me that I could file a "goodwill" claim, but that it could only be submitted via my local dealership. So I went to local dealership to discuss my situation. While there, I inquired about the projected costs of engine repair/replacement if the claim was denied and was given a copy of an estimate in the amount of $8500 prepared for another customer with the same make/model/year vehicle with similar problem - catastrophic engine failure. I decided to proceed with claim and paid to have vehicle towed to the dealership. It was only then that I was told that an initial inspection fee of approximately $200 would be assessed if repairs were not completed. Once the initial inspection was done, I was given an estimate of repairs exceeding $18,000! They also told me that Hyundai corp was requiring additional diagnostic tests in order to complete its review of my good will claim that could be performed at an additional cost of $600! At this point, I'm being asked to throw money away. This car is a lemon. My family has endured undue hardship due to this incident. I am angered that a company would not go through the effort to make things right. People do not spend $49,000 on a vehicle expecting this to happen.

While traveling at approximately 60mph I decelerated to make a left turn through a busy intersection (evening rush hour traffic). While decelerating, I felt the car give a "shudder" at which point I looked to the dash to see the check engine light blinking, then the battery light illuminated. At this point, while passing through the intersection turning left, the engine shut off, as well as the power steering. The car coasted through the intersection and came to a stop barely out of the crossing lane. It would not restart and I was forced to push the car with my family inside to a safer position. Prior to this event there had been no drivability issues, no other times that warning lights had come on. The only issue of note that I have had for this vehicle is a seemingly excessive amount of engine oil being consumed. The car is at a dealership now and I am told that the engine needs to be replaced, with no explanation for the failure.

While turning right out of a parking lot onto a two lane road, the vehicle suddenly stopped accelerating for 3-5 seconds as a truck was bearing down on us. The position of the gas pedal made no difference. The engine was running at an idle with zero response from pedal input. When it did finally accelerate, it lurched forward as the pedal was pressed to the floor. We are also experiencing what could be described as a shudder when decelerating to a stop. It typically seems to occur between 20-12 MPH. It feels as if the engine is stumbling or it is having trouble downshifting smoothly.
