- St Louis , MO, USA

Vehicle is showing transmission issues that match recall issued for same vehicle and model, problems accelerating and misfiring which appears to be dangerous too drive.

- Sicklerville, NJ, USA

the car was unresponsiveness when pushing the gas pedal, delay when accelerating, shaking, and the gears do not seem to change. this causes problems when trying to merge into traffic, make turns and anytime when acceleration is needed. We took it to the dealership said we needed a Dual Clutch kit however the vin does not have a recall therefore want to charge $2264. to fix the problem. it is obviously a manufacture defect. the car has not been inspected by the manufacturer, police, insurance representatives or others. There were not any warning lamps, messages or other symptoms of the problem prior to the failure. this problem has been going on for 6 months.

I was driving to work after dropping my son off and I took a right turn onto a street and my car slowed down and the check engine light came on, flashing. I continued to drive to work as I was one minute away and needed to get off the street asap. (where I turned had no room for pulling over). I parked my car. I had a prenatal appointment to go to, so I started my car. No check engine light when started until I got on the on ramp to the mass pike, my car went from 50 to 35 in a matter of minutes. I went into the breakdown lane until the next exit which was only a mile or so. I pulled into a gas station and called my husband to come get me as I still had an appointment to go to. After my appointment we retuned to my car and had it towed to the dealership as it is not safe to drive while pregnant. They told me it may be an engine issue and they will try to expedite my car. What annoys me is that this happened before and they claimed it was because I was over my oil change mileage and deemed it my fault and made me pay almost 300 for them to fix it. Yet I feel as if that just bought my engine time before it actually failed. This also happened with my 2015 Sonata Sport back in like 2018/2019 before someone rear ended me and totaled me. But what is my luck that this happens with 2 of my Hyundai. It is very frustrating.

The acceleration completely stopped, while driving in the third lane, northbound on the 15 freeway in the cajon pass. The dealership informed me the transmission is the cause. The car is still with the service department now. No warning lights. No check engine lights, nothing. The power in the car remained on the car acted as if it was in neutral.

Hello. I recently took my car to the authorized mechanic and had them check on an issue I am experiencing. For some reason, my car frequently hesitates when I go from a complete stop/slow roll to accelerate. For example, if I am stopped waiting to turn, often when I push the gas to accelerate, the car will begin to accelerate and then basically stop. When this has happened, I've pushed my foot down to the floor on the pedal before to make it go and it refused to go for about 20 or so seconds. Additionally, if I am in slow moving traffic and traffic begins to speed up, my car will hesitate to go forward when I try to accelerate. This is a huge safety concern. The mechanic was not able to replicate this issue, but it happens every day or every other day. It makes me scared to drive because it's almost caused accidents. I read I'm not the only one with this issue and honestly, it's a miracle no one has died yet as a result of this faulty issue.

When accelerating from a stop, the vehicle "chugs" or hesitated substantially before actually accelerating. There is usually a noticeable jerk at that point as well. Concern is this usually happens when turning and has caused safety issues related being stuck in an intersection until the transmission releases and allows the vehicle to accelerate. Several trips to the dealership have provided no repair/relief to the issue. We are always informed its a known issue with the double-clutch engine and just something we need to get used to. Most recently, the transmission is "slipping" when accelerated. This has happened at minimum 5 times in the past month.

- Omana, NE, USA

When accelerating from a full stop or yield, vehicle takes up to 3 seconds to fully respond to pedal. Vehicle will move about 5ft forward during this 3 second lag time. After the lag time, the vehicle jerks into motion. Very dangerous to turn onto a busy road with 35mph speed limit.

- Hampton, VA, USA

2017 Hyundai tuscan will lose acceleration when driving down the highway or any street. Slow acceleration from complete stop. After pulling over shutting the vehicle off and restarting it will accelerate properly sometimes for minutes, sometimes for days. This has been happening since purchasing the vehicle about 7-8 months ago.

- Henryetta, OK, USA

When coasting, the car idles rough and lurches forward. When stopped and pressing the gas, it takes sever seconds for the car to take off. This puts the driver at risk as it doesn't happen consistently- you can either take off right away or you're delayed. The rough idling sounds and feels as though the car is about to stall. In traffic, this presents a hazard.

To whom it may concern, according to Hyundai's 10 year/100,000 mile warranty, ''repair or replacement of powertrain components (I.e., selected engine and transmission/transaxle components), originally manufactured or installed by Hyundai that are defective in material or factory workmanship, under normal use and maintenance.' Currently, certain Hyundai vehicles with a dual clutch transmission have caused the vehicles to shudder and lurch, causing potentially dangerous situations for drivers and traffic. A civil action lawsuit has come out awarding anyone with these vehicles monetary compensation but has an unfair and pointless cutoff at a certain mileage that has nothing to do with the issue pertaining to the vehicles and still does not fix the problem of driver's safety as Hyundai refuses to fix the issue. Because the transmissions use computers, the issue is that there is not a code yet created to solve this issue. It is also not possible to switch the transmission out for one that does not lurch from other models as it will not fit into the cars correctly. Because of this defective transmission that threatens driver's safety, it could be viewed as violating product liability laws. This might be an issue worth investigating and the publicity could help drivers with these vehicles by putting pressure on the company to fix the issue instead of just paying them off for their silence.

On numerous occasions this vehicle has failed to accelerate. The vehicle rpms rise but it takes roughly 2-3 seconds to engage. I feel this is very unsafe especially when making a left turn in traffic. I have take it to the dealer more than once with no help. The 2016 model was recalled for exactly what I have experienced and I believe the 2017 model should be as well.

- Glendale, AZ, USA

Car engine/transmission stalls, lags, hesitates, jumps and chugs when gas is pressed from a stopped position or in slow stop and go traffic. When pressing on the gas pedal the engine/trans does not engage and move the car. After a few seconds the car will engage and jerk, and jump. The hesitation makes the car feel like it is going to stall out. Very dangerous situation. I am afraid every time I get in the car to drive. This has been going since the day bought the car

- Lindenhurst, IL, USA

From stop to 30 mph intermittent hesitation. Dangerous when trying to merge for don't know if car will move or not. It 'bucks' from start to acceleration intermittently. From low speed to try to accelerate doesn't always want to accelerate. Dual clutch seems to be the problem and maybe something else. Hyundai service did nothing to help with this problem, just 'live with it'. would they like their teenager driving such a car?? some times car lurches forward too instead of hesitation. Gas mileage terrible too. Not getting what they said, 18-20 mph, once in awhile 25 or 30.

- Myrtle Beach, SC, USA

When attempting to accelerate from being stopped at a light, stop sign, etc. The vehicle stalls for about 3-5 seconds before moving. When attempting to change lanes or merge onto the highway there is a delay. I've had the vehicle for 1.5 years (original owner). These issues started approximately 1 month ago.

- Phoenix, AZ, USA

I love everything about my Hyundai Tucson, however the transmission issues are horrible. When you take off from a complete stop, you have to feather the gas pedal to take off, otherwise the transmission will slip during take off. Driving in rush hour traffic (stop and go) makes the drive feel like I am driving a stick shift, meaning the transmission feels jerky. This is something that happens everyday and for me is a safety issue.
