Whenever i hit a bump on the side of the road, the truck jerks really badly and if im not grasping the steering wheel with all my strength, it will jerk me off the highway from the bump making the entire car go off the road. Also, each bump i hit, i hear a very very loud metal on metal knocking sound from the right passenger side of the tire area. Not sure if it is a strut assembly or engine mount that wasn't correctly bolted down during manufacturing. Also, when i press the gas pedal, it sounds as if theres some type of cable thats being stripped or something. And whenever i am holding the steering wheel straight and firmly, the truck automatically has a mind of its on at times and will jerk the car to the right or to the left while im holding the wheel still. All mechanics have said that they don't see anything wrong with it but there's obviously something wrong with it and I am scared to drive it. It has got to be a manufacturers defect on those components of the vehicle. Please remedy this or replace my vehicle with one of the same or lesser valued cars. This truck is going to end up killing me or someone else or both... Thanks

The car makes a jerking sound when switching from park to drive or reverse when it's hot. It also jerks like it doesn't know what gear to go into while driving on occasions.

- Palm Harbor, FL, USA

When shifting the transmission makes a loud banging noise losing power for a moment and then violently snapping back into gear. It almost feels like somebody is hitting you from behind. Sometimes it feels like the accelation/deceleration is tightening up right before it happens. Feels very scary sometimes and I'm worried to destroy the transmission. Vehicle was bought with 153K miles on it and it happened shortly after. Check engine light is on. According to dealer its a small emission leak.

I have a 2010 Hyundai Santa Fe and since I bought it 2 years ago when I start it and let it warm up then I put in reverse it jerks violently then I would put it in drive and it was in neutral then another violent jerk to drive. While driving it will change gears very rough like some hit me. I know Hyundai knows of this problem and doesn't expand the recall. I checked my VIN # and no recall on the transmission just a hand full.

When traveling at different speeds and upon acceleration there's loss of power for a split second, and then it's bumping real hard. It can be described as a bumping noise, clunking noise or thumping noise. More likely to happen between 50-70 mph. Also, the passenger back door lock has been working off and on. It finally has stopped opening the door entirely. I've taken it to the dealer and they have yet to diagnose an issue after two inspections. As of 7/21/20 the vehicle is still having these issues.

In Nov 2012 after purchasing the vehicle used with 38,000 miles, we notice the transmission was not shifting properly. Took the vehicle to shortline Hyundai in Aurora, co. To have them inspect the vehicle and test drive. They were unable to find any issues with the vehicle during their inspection, no codes. We still noticed the issue for the next few years. Fast forward to Nov. 2014 - we decided to try another dealership in centennial, co. Arapahoe Hyundai. The vehicle had 52,000 at this point. They confirmed the transmission had a harsh engagement in higher gears, still no codes. They stated the fluid was low and topped off the fluid. Through the following years the issue was still present. Feb 2018 the extended warranty expires and the issue at this point is very noticeable. 5th gear would hesitate up sifting to 6th gear, along with a delayed reaction on a downshift from 5th to 4th. Once the downshift engaged there was a hard band into 4th.June 2018, 79,850 miles - feeling brushed off by the local Hyundai dealers, we decided to take the vehicle to a local independent repair shop. The transmission fluid was in need of change, so we changed the fluid. The fluid change eased the harsh shifting slightly. As of today Feb. 2020, 91,150 miles - the transmission need to be replaced at our expense. The vehicle drive fine until it hits 5th gear. The downshift is now very hesitant with an extreme bang once it engages 4th. There has been an known issue with the transmission, which is a safety concern. Hyundai has known about this issue but refused to do anything about it, other than putting a band-aid on the issue.

The automatic transmission slips and then violently kicks into first gear when starting out. It will also slip while driving along and then kick back into gear with a bang sound. These slips seem to occur when the engine is cold( just started and temperature gage reads at or near C). I have taken it to the dealer 3 times over the years and they tell me they find nothing wrong. The problem recurs at least weekly.

Dealer reflashed (upgraded?) the computer during an unrelated door lock repair. Afterwards, the transmission disengages at low speed/coasting, then reengages violently. When requested to restore the computer to the original factory program, the dealer said it cannot be done. There have been subsequent reflashes installed to improve the situation, but to no avail. Dealer says "the computer just has to learn my driving habits". it's a dangerous situation when you're not aware of the disengagement, the engine RPM increases, then a sudden engagement occurs.

We purchased the vehicle 7 months ago with just over 62K miles. The vehicle will not go faster than 30 on the road. Dealership did a diagnostic and told us we need to replace the transmission and cd axle. After research there was a recall on this model's transmission. Ours was built 3 months after the recall but is doing the same thing. Safety issue and a quality Hyundai should stand behind and repair. We have the diagnostic report from the dealership.

Vehicle has 107K mi and automatic transmission needs to be replaced (symptoms: Upshifting lag and "thunk" when downshifting at 15-25mph). According to dealer, it can not be re-built due to design and must be replaced. Car has been very well-cared for and driven less than 10,000/mi/yr for the last 8+ years. There was a recall on some 2010 Santa Fe transmissions but dealer says ours was not impacted. We feel that a transmission that fails after 107K gentle miles must have a design flaw.

Mostly shifting into first gear or backing up, you get a very hard bang, as if you hit something. City street mostly turning.

Since the day I purchased this car, the transmission bangs hard when shifting gears occasionally. I have had it into the shop 3 or 4 times but they keep telling me they tested it and it's fine. Now I'm almost out of my warranty and I'm afraid they transmission is going to go. I read that I'm not the only one complaining about this. What is being done about this?
