Dual clutch transmission (dct) / 1.6T engine start from stop acceleration stuttering, stalling occurs from initial take offs, while idling in stop/go traffic creates potentially dangerous drive/passenger situation in traffic especially when crossing traffic patterns and lane merging/passing. Issue has been brought to the attention of Hyundai corporate and two local Hyundai dealerships. Both parties indicate lack of knowledge on how to properly drive dct transmission and provided both video and written training packages. Both training mechanisms failed to resolve the issue. Supposed software updates by the leasing dealership failed to resolve the issue also. Issue is still active and latest visit to dealership failed to find any issues with no repairs or software updates taking place. Senior technician indicated Hyundai leadership at corporate are acutely aware of issue but choosing to not act accordingly/appropriately.

Traffic was clear and attempted to turn left. While doing so, the vehicle abruptly stalled and I could not accelerate to my lane, causing brief panic since I was in the vehicle with my baby and a freightliner was now approaching. The vehicle responded in the same manner while my husband drove it several days later. Additionally, there was a horrendous smell coming from the vehicle as we traveled in traffic at about 3mph or less. My husband and I were on edge and just wanted to get home safely without any further issues with the Tucson. We purchased the vehicle from Hyundai of longview on November 29, 2017.

Vehicle hesitates from a stop when trying to accelerate. Engine just revs and then lurches forward when transmission final engages. This can take several seconds. Hyundai states that this automatic transmission should be driven like an manual transmission. This is an ignorant excuse to hide a problem that they are well aware of. This is happening to so many people so why will the NHTSA not hold Hyundai accountable for this defect in the drivetrain" I specifically asked our salesperson if the issue had been worked out before we signed and he stated that the vehicles no longer had the problem. If Hyundai denies there is a problem whey did the salesperson acknowledge this to me? the issue has happened over 20 times to my wife and I in the past year and the vehicle has 10,500 miles on it. Hyundai states they it is performing as designed and closed my case. They didn't even offer to have me take it back to the dealer for service. This is because they know there isn't a fix and is a potentially fatal flaw. We have almost been hit numerous times because of non responsiveness from the transmission. Please hold Hyundai accountable for replacing the transmission. If a different transmission will not work with the current engine then they should buy the vehicle back or trade without a loss. The date field below only allows for one date" this has happened over 20 times as mentioned above.

I have owned my 2017 Hyundai Tucson since 10/20/17. In the last year I have had it at the dealership 3X for the check engine light. Twice my vehicle had performance issues while entering the highway and acceleration. It is life endangering. When accelerating onto the highway, the engine loses speed. The RPM gauge starts going wacky, off the charts. It will rev to 5 RPM back down to 3 RPM and back & forth. When the foot is on the gas peddle trying to increase to highway speed, the engine will go to 45 mph. When one a highway where the speed limit is 70 mph, it becomes life threatening. When I finally reached a speed of 70, it would go for a short time and then decrease to 50 mph. Very scary. Twice it was in service for the same performance issue. The 2nd time they replaced boost sensor range. It works ok now. However, the shifting of the transmission is hard and seems to shift improperly. It too is tied to the acceleration. Hyundai that is the natural performance on the engine & transmission. The last check engine was an alternator failure. I have owned 3 Hyundai's. I have helped my daughter buy her 2 Hyundai's. my mother as well. I have never seen these kind of issues. Also the natural hydraulic closing on the back door is a real safety hazard. One day the door started closing while my body was half inside. There should be a sensor to detect when there is an object in the way. That too is caused for alarm in safety. These 2 issues that I have written about can & will cause death.

I have had the car one yr. And have had an ongoing acceleration issue. It is becoming more frequent and scary. It hesitates terribly upon acceleration whether in regular mode or sport. The vehicle hesitates from a standstill and while moving. Below it asks for a date when this happened but it happens all the time. I used to own a VW cc which had a dual clutch and never had this issue.

- Longs, SC, USA

Vehicle currently has 25, xxx miles on it. It has the 1.6L turbo engine with dct (dual clutch transmission). It is very unpredictable in regard to making a smooth start from standstill. The is considerable lag and jerking before the vehicle will respond with forward motion. Sometimes, just releasing the brake at a stop, the vehicle will buck and jerk without even touching the accelerator pedal.this is a safety hazard as it is unpredictable on the severity and when it will occur. Taking the car to the dealer was not of any help. They performed scans and said everything was "normal". they gave me a paper description on how the dct operates but that does not solve the problem. They basically said that's the way it is, just get used to it. Performing a goggle search yields many similar complaints. Hyundai has not owned up to this problem as far as I can tell. Perhaps if enough owners report this common problem, Hyundai will be forced to perform a recall with a solution to address the problem. This problem has been noticed continually on an intermittent basis since Oct of 2018.

I'm writing this in regard to the issue I am having with our Tucson we bought new about 2 years ago. From early on it seemed the transmission loses power/ chugs. Hyundai sent out a survey about a month after we bought the car and I stated my issues then. My wife has had it in the dealership to have this looked at numerous of times just to be told they reset the transmission, can't find the issue or Hyundai is aware of this issue and looking into it. But looking in to this online seems this has been going on for quite some time. This issue is a safety concern as it loses power/ chugs when turning left in to oncoming traffic or when passing someone. At this point seems Hyundai usa is giving us (and others according to online) the run around. I would like to get this issue resolved quickly.

This car stalls intermittently when accelerating from a stopping position to a moving position. I've stopped at a stop sign and when I push the pedal to accelerate the car pauses or hesitates. After a few seconds, the car thrusts forward, that that hesitation is scary and not safe. This also has happened whilst in traffic. As traffic builds it causes the car to make multiple stops. As I've gone to accelerate again I've had the car hesitate causing cars behind me to honk and creating an unsafe driving pattern. We purchased the car brand new, so this is really disappointing. I have reported to the dealer 3 times and every time they tell me there is no fix for this problem. This is not exceptable. This is a big safety problem your Agency has enough data to make Hyundai fix the problem.

- Baltic, CT, USA

When in city driving, vehicle jerks between 1st, 2nd and third gear. When in a quick stop vehicle fails to accelerate right away. Both intermittently concerns. Spoke to my local dealer and they state is a know issue with this model vehicle and that is just the way they are. Unacceptable

- Margate, FL, USA

Transmission stutters and bucks on initial acceleration from a standing position with high variable revolutions and latent unintended acceleration resulting. Occasions of erratic forward motion occur at any speed when pedal is pressed but not always at same location of pedal stroke. A recent occurrence of loss of acceleration while turning left and merging into traffic lanes left the vehicle and occupant stationary and vulnerable for several seconds. There appears a progression of increasing frequency and severity to these events that I have reported to the dealership on several occasions, the latest being on 10/8/18. They stated they had been receiving or hearing of similar issues.

- Winchester, VA, USA

While driving the Hyundai Tucson at times the automatic transmission does not engage to the next gear. We were driving on the freeway and went to make a lane change as a result of the transmission not engaging properly we were almost hit by a big rig. We have taken it to the Hyundai dealer we bought it from but they keep trying to tell us it is the way my son drives. But the problem is that it also happens when my daughter-in-law is driving. My sons drives with two feet and my daugher-in-law drives normally. To give you an example last Friday my daughter-in-law drove me to the doctors. We traveled about 20.5 miles round trip and in the time the transmission did it nine times. I feel this is a safety hazard. I have complained to the hyundia Corp but all they have done so far is to open a case number for my complaint(#11611806)

- El Monte, CA, USA

The 2017 Tucson sport has the 1.6 turbo with the dual clutch transmission. When pulling out into traffic, one never knows if the car will respond to the gas pedal and accelerate or just stumble along. This is a known problem, and there is a recall or similar for the 2016 with NHTSA. The dealership (kearny mesa Hyundai, san diego) tells us that "they all do that" when we took it in for safety concerns and repair. Any subsequent requests for repair were met with "it will cost you 150 dollars to check it out if it's the same situation as before with no solution". this car is a danger to us and others on the road. It also tends to go into some sort of leaf blower mode sometimes when you hit the brakes, where the revs soar but it doesn't act like it downshifted. This is not a mixup in brake/gas pedal usage, like the unintended acceleration problems weve all read about with other brands. The dct has a mind of it's own and is a hazard on the road. The problems are when the vehicle is in motion, and it can happen anywhere, at random, highway, freeway, pulling out of a driveway... anywhere. Please help get these dangerous cars off the road. Not sure what documentation you want, but the car is under warranty, and was bought in Aug 2017. Cars with this engine/trans are still for sale in the showrooms nationwide, a known danger to all concerned. The dealership service mgr has told us how there are a lot of unhappy customers out there with 1.6 turbo/dct drivetrains, and yet they are selling more by the day. Yet there is no support other than the one time attempt and "they all do that". help.

Tucson with dct accelerates very slowly after coming to a stop, basically unresponsive for a couple seconds. This happens all the time in city driving no matter what direction I go after the stop. I noticed this vehicle stays in 2nd gear unless it comes to a complete stop for a full second. Anything less than that and the car stays in 2nd gear and then lags and stutters when the accelerator is pressed. I don't know for sure but a vehicle that doesn't downshift to 1st gear when basically stopped might be an issue.

- Lombard, IL, USA

I purchased a 2017 Hyundai Tucson a month ago and it has dangerous and defective transmission behavior. There have been multiple times when I have pressed the accelerator and the car moves very slowly for a few seconds then suddenly lurches forwards. I have also pressed the accelerator while driving and the car has actually slowed down! there was a scary incident when I was turning into traffic, and instead of behaving normally, my car slowed down, putting my wife and I at risk of being hit in the side by the approaching traffic! this cars behavior is dangerous and somebody will die because of it (if nobody has died already). I have taken the car to my local Hyundai service center and they said nothing was wrong with it, and that I will "get used" to driving it, because it is a dct (dual clutch manual transmission). This car was marketed as an automatic. I know how to drive both automatic and manual transmissions, and I have never seen a "properly functioning car" behave like this. I have reached out to Hyundai corporation and they have not gotten back to me about a resolution, but in the mean time this car is very unsafe and needs to be recalled!

- Fort Wayne, IN, USA

Extreme hesitation when pressing gas pedal from a stopped position with the ac on in high ambient temperatures (in a non-dct SE plus model) creating a dangerous situation. Auto trans adaptive values were reset by technician with some improvement, but hesitation returns shortly thereafter. Difficult to reproduce and/or diagnose since hesitation seems to only occur when the outside temperature is 85F-90F or higher and car is at operating temperature with the ac on.
