Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2015 Hyundai Santa Fe owners, lightly cleaned up (personal details are redacted by NHTSA).
Recent cold weather starts in the morning (40-50 degrees fahrenheit) have caused my car to have poor or stalled acceleration. It will occasionally not go past 20 or 40 mph while the RPMs rev high. The DTC error code would read P2565 as a pending code. An independent mechanic changed out my transmission fluid and switched out my boost pressure sensor but the problem is still there. Hyundai says that they need to replicate the problem but it does not occur when I take it to them so it's very hard to have this intermittent issue diagnosed by them. This is a very dangerous issue in my opinion if your cars engine revs high without accelerating and can potentially cause serious accidents and injury. I know I'm not the only person experiencing this issue as I've read on online forums of other car owners describing the same issue. …
I drove approximately 40 miles to a gas station and went to park in a parking spot and my passenger exited the vehicle and yelled my car was in reverse even though I thought it was in park, upon trying to again put it in park it would not go in the park position. I was stuck in reverse and the vehicle would not park without using the emergency brake. No warning lights or any other message from my vehicle regarding this issue. I then put it in drive and drove home and again was not able to put the vehicle in park, after attempting numerous times and using the interlock system I was able to put it in park. This is a huge safety concern as there could have been someone behind me when parking and not even realizing the car was not in park as it was snowy out and the car was still for a moment before reversing. Upon looking on google it looks as if others may have had this issue as well.
We were on our way home from the children's hospital in Philadelphia for my daughter (4 hours away from home) and my 2015 Santa Fe with the 3.3L motor began to knock. My dad (who is very mechanically inclined) pulled over at a gas station and checked oil and other fluids. It was low, even though I just had oil changed 900 miles before and it was checked before our trip to the hospital. We bought oil and put it in. Knocking was still there but was not as loud. We got back on interstate. Few miles up the road it completely lost power, extreme knocking, no lights on in the dash or any gauges out of normal range. He checked oil and it was completely empty but there was no oil trail or anything. We coasted into a crossover and that's when he saw the connecting rod under the car.
While driving, there was a noise coming from the car on acceleration. Had been using cruise control and when canceled cruise, and accelerated- the noise became worse. Car stalled and I was able to get it to the side of the road without incident. Lucky there was no other vehicles on the road at the time. Checked the oil and level was fine and no temp issues indicated. When I tried to restart, an engine light came on the dash. Got the car home by coasting in neutral, it was only 2 blocks. Couldn't get an appt for repair for over a week. Had car towed to a repair shop and they said it was a Variable Valve Timing Solenoid. On first drive after replacing this piece- indicator light came on the dash again. Left the car where it was.
It appears to be a problem with all the Hyundai Santa Fe Sport. It has abs, downhill, stability control lights on at the same time. It appears to be wheel speed sensor but they do not know which one. The service manager had said it happens to be a lot of the time the rear sensor that goes out. The service manager made it seem like it happens frequently. When I check online a lot of owners appear to be having the same issue. THREE LIGHTS, ESC, DBC, and ABS warning lights turn on. I am in fear for my life, due the safety on the road if the tires would lose control!
This vehicle is an All Wheel Drive. While approaching an intersection right before coming to a stop the vehicle's rear differential locked up. Attempted several times but the vehicle would not move forward. The vehicle would drive forward but would move in reverse. I drove the car in reverse back to the house. We lifter the car and the rear differential lock while moving forward but works moving backwards. My wife is afraid that even if they fix this issue what if its a defect and the rear axel locks up at higher speeds the outcome would be different.
engine replacement can be avoided you should use fuel injector cleaner every 3000 miles, sediment clogs injectors, and pistons which fuel leaks into oil pan, causing oil/fuel mixture to burn, creating overheating, which leads to oil burning, and eventually engine seizing. If you use fuel injector cleaner every 3000 miles this will prevent needing to replace motor.
During routine vehicle operation when entering an interstate highway, , the vehicle developed a loud knocking sound from engine bay along with high RPM abnormal shifting. Vehicle was stopped as soon as possible in the safety lane when it stalled and shut off. No warning lights were present during the time of failure. Vehicle was towed to home of residence.
The engine is continually knocking. It has caused the powertrain system to start to fail. The interior portion of the car with electrical is malfunctioning and causing the car to lag. Many attempts have been taken to get the vehicle fixed to no avail. $1,000 just to take out the engine to diagnose the problem.
Engine light coded 1326 on July 28, 2023. Car engine was replaced Aug- September 20, 2023. September 27 the engine light coded 0263. October 4 the engine light coded 0263. October 5 the engine light coded 0263 October 13 the engine light coded 0263.
