2017 Hyundai Tucson: transmission slipping

Filed Jan 16, 2026 · Transmission · RI

The vehicle has a transmission (powertrain) malfunction that first appeared in July 2025, a few weeks after I purchased the vehicle and after the warranty had expired. At the time the issue began, the vehicle had well under 80,000 miles. The transmission slips, fails to properly engage, and cannot provide sufficient power, particularly when accelerating or driving uphill. The vehicle struggles to move forward and behaves unpredictably during normal driving conditions. This defect has put my safety and the safety of others at risk. On one occasion, the transmission failed while I was driving and I became stuck in the middle of an intersection, unable to accelerate, creating a serious traffic hazard. The issue has been reproduced consistently and has persisted despite repeated transmission fluid services. Multiple mechanics have inspected the vehicle and have indicated that the problem is not due to lack of maintenance, but instead is likely caused by the transmission not being properly filled with transmission fluid at the time of manufacture. Despite servicing, the problem continues, indicating an internal or manufacturing-related defect. I have also been in contact with multiple owners of the same make and model vehicle who report the same transmission failure, suggesting this is a widespread issue rather than an isolated incident.

There is an intermittent problem with the transmission. It’s impossible to predict when the transmission will slip. When navigating traffic, it has happened multiple times trying to pull out across oncoming traffic, and the transmission begins slipping so badly in a couple of instances nearly causing a side impact. There are no recalls related to this, but the dealership confirms it is common… the fact that it is intermittent makes it worse. You get used to the transmission performing as it should… Next thing you know it slips when you can’t afford for it to slip..

My transmission has failed fully. It cannot even reverse. I took my car into Hyundai several times to check on the issue and they said the same thing, that the transmission slipping is a standard issue for dual clutch. I told them over and over that this is different. I did some research as to how to have them cover it and have it changed but the dealership said nothings wrong. Fast forward and now my cars transmission is fully gone and it probably won’t be covered when I know that it should have been part of the recall ! Just this year I’ve spent $5000 on repairs for this vehicle and now I’m looking at another $5000 for only a 7 year old vehicle. If that does not constitute a lemon I don’t know what does.

Transmission is slipping or not adjusting when driving. Very slow acceleration and it feels like the gears are not shifting properly

Excess Oil Consumption, Gear slipping, Dual Clutch, Fly Wheel, Oil found in the Turbo inlet, Clutch dust found in the transmission, Encouraged to just keep adding oil and drive the vehicle. Encouraged to drive the car when there was assumed to have contaminated transmission fluid. Encouraged to keep extra oil in my car since it was consuming oil rapidly but was still considered with in specification from Hyundai. Encouraged to add oil and drive the car after it stalled and quit working. This is a known defect with Hyundai's. Some even catch fire and also stall at high speeds while being driven. This is irresponsible, hazardous, and neglectful behavior that could have hurt or even worse killed someone.

The car has been having numerous acceleration issues, it can take upwards of 30secs to actually start moving from a light or stop sign. It also seems to be shifting late and/or slipping. This had caused me to be stuck at a light in the middle of the road and almost hit by another car. Also, my engine completely failed within 5mins, I was driving and the check engine light came on, then the oil light, then the engine started smoking, and then the car died in the middle of the road. The engine completely seized in 5mins. I had all oil changes done and there was never an oil light on saying it was low. When the dealer checked the engine there was no oil, probably from the rod breaking out. There. Was some if the same issues with the same year that got recalled and fixed for free. I got quoted $16,000 from the dealer. That's more than I owe and what the car is worth. I'm stuck with no vehicle and don't know what to do.

I am the sole owner of a 2017 Hyundai Tucson Limited, (AWD) with the 1.6L engine, 7 dual clutch transmission, with 46,000 miles as of today Thursday, February 23, 2023. Currently, I am experiencing problems with the engine/transmission stuttering and vibrating, the gears slipping, and with the inability to accelerate when merging into oncoming traffic. In addition, what frightens me the most is when I am applying the gas when driving and the gears stick causing a brief halt in forward motion then, suddenly progressing forward with a quick burst of speed. On many occasions, I have shared my concerns with the dealership from whom I purchased my vehicle from Hyundai of Chantilly, located at 14848 Stonecroft Centre Court, Chantilly, VA 20151. I have been told that the dual clutch transmissions are trash in so many words and I have been quoted a price of $2000.00 to have the transmission replaced. I am at my wit's end and unsure of my rights and to whom should be held accountable. Therefore, I am writing the federal safety agency for assistance.

I have had my 2017 1.8L eco Hyundai Tucscon for 3 years now and recently it's been giving me signs of problems that are great concerns for safety, as well-known for this models; it only 62091 miles as of the day of this complaint. On Jan 15. 2023, I noticed that each time I start the car, it takes a little bit longer, then you hear a rattle sound and shaking of the engine block, then it start. Or the engine would suddenly slip, followed by a brief rattle sound while driving. I took it in for service to Manly Hyundai in Santa Rosa on Jan 27, 2023, but the mechanics there told me that they could not find where the problems are coming from, and that I would need to wait for an engine light to come on, as any diagnostic at this point maybe unnecessary and costly. Had I known that the 2017 Tucson had so many issues and recalls, or engine defects, specially the slipping or shaking on acceleration from idle, I would never put my money on a commuter like that. I AM STILL WORRIED FOR THE EUGINE NOT TO BLOW UP AS PER PREVIOUS INCIDENTS WITH THIS MODEL. Common issues: The18.0-liter eco 4-cylinder engines, which may have defective rod bearings. The bearings may wear prematurely. This can cause the engine to stall during operation. In extreme cases, a damaged connecting rod can puncture the engine block and cause the engine to leak oil onto hot components, leading to a fire. Please do something.

The transmission consistently slips, or does not engage. It sputters, jerks, or simply does not go when the accelerator is depressed. One incident was so bad that when it finally engaged, it threw me back against my seat then sputtered and moved ahead slowly, all while merging into traffic. Very dangerous!
