2017 Hyundai Tucson: shudder or vibration when accelerating

Filed Dec 16, 2025 · Acceleration, Transmission · PA

Issue was first noticed in October 2025 - there are roughly 70k miles on the vehicle. It is a 2017 vehicle, and has regular service (oil, inspection). There was a class action lawsuit for this issue (wylie v hyundai), which was settled prior to the purchase of the vehicle. Vehicle stutters when shifting into and out of first gear. A local mechanic and hyundai both confirmed that it was a transmission defect. The Hyundai dealership initially thought it was an actuator issue, but has since said that it is a faulty gear assembly. it has a DCT (dual clutch transmission). Vehicle suddenly stops and is erratic when driving. Coming out of a stop risks the vehicle shuddering; going through an intersection or turning cross traffic is extremely dangerous as the vehicle could stop momentarily and cause a collision. Vehicle is unable to maintain flow of traffic. The problem appears to be widespread - there are various forums we found where others have this same issue. There were no warnings on the dashboard prior to the issue. When issue appeared a check engine light was displayed.

My 2017 Hyundai Tucson Limited 1.6L Turbo (with 7-speed EcoShift DCT) has ongoing transmission problems. The vehicle hesitates, jolts, and sometimes fails to accelerate from a stop, which creates a serious safety risk when entering traffic or crossing intersections. The problem has been reproduced and confirmed by the Hyundai dealership in Fairfield, CT. They diagnosed the transmission and recommended a complete replacement at a cost of over $7,000. This issue matches the defect described in the federal safety agency Recall 16V628000 and Hyundai Service Campaign T1B, which involved the same 7-speed EcoShift DCT in 2016–2017 Tucson models. However, my VIN was not included even though I am experiencing the exact same safety defect. No warning lamps appeared before the hesitation/judder began. The safety risk is significant because the vehicle can fail to accelerate as expected in traffic, increasing the chance of a crash.

My vehicle began experiencing issues around 83,000 miles. The engine started burning oil, showed shuddering during acceleration, and there was a noticeable smell of gasoline inside the cabin. Eventually, the car wouldn’t start, so I had it towed to the dealership. The technicians confirmed it was running rough and behaving abnormally. The Hyundai dealership conducted a full inspection and diagnosed several issues. They replaced the spark plugs, performed a GDI-safe induction cleaning, replaced the coolant and brake fluids, completed a transmission fluid service, installed a new battery, carried out wheel alignments, and changed the cabin air filter. All of this work was completed in October 2024. However, in December 2024, I had to return to the dealership because the fuel smell inside the cabin persisted. Although they couldn’t find the source of the issue, the smell eventually disappeared after the visit. Following that, I was advised to check my oil every 3,000 miles due to the GDI engine's reputation for burning oil quickly. Despite this, the car began running rough again, and when I checked the oil, it was completely dry—well before reaching the 3,000-mile mark. I had to get another oil change sooner than expected. Unfortunately, the issue continued. I brought the vehicle back to the dealership for another inspection. They suggested starting a monitoring process where I would bring the car in every 1,000 miles to check the oil levels. After driving 1,000 miles, the oil level was just slightly above the low mark—still not normal for such a short distance. I urgently need assistance to move forward with the engine replacement process before my warranty expires. I am currently at 91,000 miles.

The problem began in mid to late April 2024 with the Tucson shuddering in the driveway while moving forward slowly. This vehicle has a 1.6L turbo with a dual clutch transmission. The mileage was around 96,000 miles. Once on the road, it ran fine. Approximately a month later the check engine light came on and it began hesitating upon acceleration. It would change to the next gear, accelerate and slam me against the seat! Whenever I try to accelerate too fast, it hesitates and loses power until it "catches" and starts speeding up. This is very dangerous especially when accelerating from a complete stop or after a turn. It also has trouble going up a hill and has actually died out 3 times while attempting to go uphill at a low speed. I am the second owner and it is out of warranty. I have contacted the local Hyundai dealer but their shop does not have a very good reputation and is always backed up for 3+ weeks. They also charge $230 or more to hook up their code reader!! I've already taken it to 2 other shops where that was done at no charge. The code was P073F - Unable to engage gear 1. Of course the only option I've been given is to replace the transmission for $3000 or have it rebuilt for $4100. This problem makes it very dangerous to continue driving it. I get the oil changed every 5000 miles. Of course it's almost paid for but I'm afraid if I try to trade it in I'll be lucky to even get enough to pay it off. I have been endlessly researching this online for recalls, updates or remedies. I want to know if replacing the entire transmission is the only option or is it a component of the transmission or a computer module that is the cause. How do I know the new transmission won't do the same thing?

The DCT transmission shudders when first accelerating then smoothing out . it also at times will not accelerate at all for several seconds. This can be very dangerous while pulling out into traffic because it doesn't do it all the time.The dealer does know about the problem and has been confirmed . No warning lamps .

There is a problem with the dual clutch transmission on this 2017 Hyundai Tucson. There was a class action suit filed 2016 for transmission defects including the hesitation and shuddering issue and also grinding noises. I purchased this vehicle in 2020 with only 6600 (yes, hundred) miles not knowing of any problem or issues. 2023 in Tucson AZ when the weather started getting very warm end May, June I started noticing a bit of hesitation, sometimes like a grinding noise. This was not happening all of the time but from the reviews it happens when it gets warm. The shaking or shuddering as they call it and hesitation is very prominent and continuous now. When I had my car in for oil change in Tucson at the Hyundai dealer the service manager even drove it and said it was the dual clutch transmission. I asked about replacing the transmission then and he said that I did not have a warranty. That was another issue as I was told by Hyundai corporate before buying the vehicle that the 100,000 warranty would transfer to me. I found out in July it did not. I opened a case with Hyundai service who contacted Eastside Hyundai and I even got a call from the svc mngr who drove the vehicle. He said that Hyundai would not end up covering it all even if they said they would, they may have to have car for awhile and I would need a rental, and anything else negative about the situation. That manager never called back so caseworker called another dealer numerous times and said that they could check out my car in November. This vehicle is getting worse and possibly a danger. Hyndai take is November, take it or leave it and thats all they can do. This can cause long term damage to the engine and other parts. I need some help with this if possible before resulting in litigation. Are you able to advise on this issue and if you have even heard about. No accident has occured with this vehicle YET. I have approximately 21,000 mile on my vehicle now.

My car shudders upon accelerating at low speeds and hesitated to respond to the gas pedal at low speeds. This shows itself when taking left hand turns where the car will stall for a second or two while turning before the car finally pops and the acceleration kicks in. The transmission feels unresponsive. This has been happening since my car had 5k miles on it but is worse now that it has 35k miles on it. The dealer says this is a characteristic of the dual clutch transmission, and that it’s normal, but it feels extremely unsafe and not normal for an automatic transmission.

My daughter was driving on expressway the vehicle suddenly lost power. Vehicle began to shudder and became difficult to steer and control. On board diagnostic codes P0300 & P0301. Towed vehicle to my independent mechanic. His diagnosis was mis-fire in cylinder 3 and total compression loss in cylinder three. Major engine failure. Vehicle has 1.6l Gamma GDI engine. Vehicle was then towed to Hyundai dealer. Awaiting diagnostic from dealer ( four week backlog), but there where 85 failed engines ahead of me. Called three other dealers, all had diagnostic waits for engine failures exceeding 5 weeks. If failure is even covered the wait for replacement engines is stated as one year. Sudden loss of power impacted safety controlling the vehicle. I think the issues with this engine class will be well known to NHSTA and report so the size & impact of the issues is best understood at NHSTA.
