While driving the vehicle, while accelerating the vehicle would lose power or disengage from gas pedal at 17 mph and then again at 26 mph. After about 3 miles the check engine light came on and a TCM warning appeared on the radio screen. Immediately took the car to the dealership and was turned away since I didn-€™t have an appointment. On my way home from the dealership I made a stop at a store. I reversed out of the parking spot with no issues. When I put the vehicle in drive, it would not accelerate. I could drive in reverse but not forward. Vehicle was towed to the dealership. Diagnostics revealed it was a failed TCM. Further research revealed this same issue occurred in 2016 models. How was this not fixed or prevented in later models?

Powertrain issue. Multiple times the after stopping the engine revs for a few seconds and then the vehicle will lurch forward. It acts like the CVT transmission has a delayed response to the accelerator. The condition comes and goes and sometimes it happens multiple times in the same trip.

Car has no power when accelerating, when accelerating from a stop the car revs but does not move, then when it does move it takes off like a rocket, in slow moving traffic 5 mph, you accelerate and the car seems like it wants to stall, a lot of hesitation, In fast moving traffic, if you want to merge or pass another vehicle you must give yourself ample time and make sure it is clear to make your move, if you need to get out of the way really fast you cant, its very dangerous and Hyundai needs to move quick on this before something really bad happens to someone.

my 2018 Hyundai Tucson starting having lurching issues on when first started. i have to back into my driveway so i dont have to go in reverse then go forward. it jerks back and forth so hard. It finally took its toll on the transfer case and it exploded internally. the Dealership said they had never seen this before. i was hoping that was the cause of the issue but it wasnt. Still doing it and am afraid it will do it again. i was under warranty when it happened, so teh $2000 replair was covered. i'm concerned it will happen again. teh problem goes away after it's been completely warmed up. but like many others, its a scary issue when first started. it also will also shift hard when it firsts get's going (after the initial hard lurching back and forth). i dont know what to do. Love the car otherwise, but concerned with ever buying a Hyundai again.

When merging into traffic, the car lost all acceleration and the transmission revved to a very high rpm. This has been an ongoing problem since the car was purchased. The dealer keeps saying they -€œcannot replicate-€. This car is going to kill me.

Rod bearing failure. Sounded like a tractor all of a sudden and stalled every time I-€™d come to a stop. Had it towed to the dealership. Awaiting word from Hyundai as to whether the warranty will cover this. Checked oil and wasn-€™t low. No check engine lights or oil lights or anything ever came on. No noises prior to this happening. Kept up on routine maintenance.

The vehicle almost stalls and doesn't want to take off 1st thing in the morning then suddenly it accelerates abruptly well above the amount of pedal pushed. It also has inconsistent shifts at anytime during a drive. Sometimes it won't shift until we leave off the gas. This has been twice in for diagnosis at Rom Marhofer in Cuyahoga Falls, Ohio 44221. Both times they tell us--they could not get the vehicle to produce the symptoms. It does this everyday of the week for us--everyday. The service writer says this is common for the dual clutch transmission. This is a safety issue with not having power to move then suddenly--wham.

About 6 months of owning this vehicle, I started noticing while sitting in traffic that when letting off of the brake the car would start to jerk as you gave it a little throttle. I took the car to the Hyundai in Glendora where I purchased the vehicle from and they stated that there was nothing wrong with it. The issue continues to this day and I have voiced the complaint each time I bring the Vehicle in for maintenance. One of the service techs said that they felt the hesitation with the transmission but said that it was not bad enough to fix per Hyundai policy. This car is equipped with the Dual Clutch Transmisson because of the turbo. I have been dealing with this problem now for about 2 1/2 years and I feel that it is a safety issue being that the jerkiness and the hesitation could cause a crash. I actually talked to someone at another dealership and he told me that there was a Class Action Suit for this problem and to go that route. I just want Hyundai to own up to the problem and fix the issue.

Hyundai has historically had an issue with the dual-clutch transmission and the vehicle is available for inspection upon request. The vehicle frequently shutters / shakes at a stop and when accelerating from a stop. Additionally, the vehicle occasionally loses power to the wheels when driving-up a moderately steep grade. Additionally, the vehicle has delayed acceleration when trying to increase speed from a constant speed. This has put my safety and the safety of others at risk by being unable to properly accelerate into a turn while driving at highway speed, by being unable to keep up with the speed of traffic while driving on the interstate in the mountains, by being unable to drive in adverse weather, and by not being able to account for the jolting of the vehicle in busy city traffic. I've taken it to two manufacturer dealerships who have ran a shutter test and could not generate an error message, but acknowledged the effects felt when driving the vehicle and the commonality of the problem. They said their hands are tied if the manufacturer's testing generates a pass result. There have not been any warning lamps or messages. To date, I have been unable to come to a resolution, but the vehicle is dangerous to drive.

My 2018 Hyundai Tuscon has been having major issues with the dual clutch transmission, which has put myself, my family, and others in very dangerous situations. Everyday when I start my Tuscon and accelerate, it stutters/jerks like it-€™s going to stall and will not accelerate/shift. It eventually starts going, but I have to pull out onto a street, which has been unsafe when cars are speeding up behind me. It does not go up hills well at all. I turned onto a road where there was a decent sized hill, but nothing major, and nothing an SUV should have a problem with. My previous CAR could drive it just fine. You-€™d think an SUV could as well. Nope. Very scary moment. My Tuscon made it not even half way, and just stopped. I was pressing the gas, and it just revved it up with no motion. I braked and tried it again, and it still would not go. I had to roll backwards down the hill. This was the only way to my destination. I rolled down, and put it in sport mode to try that. It still would not go, and did the same thing. I tried again in regular mode, and it still would not go, only this time I had a car behind me. The car had to back down, and I rolled back a little bit, then hit the gas in drive and it eventually made it, but definitely very scary and unsafe, and it put others in danger as well. I was going to church one morning, and the speed limit on the main road is 60, which is what I was driving. I had to slow down to turn, and had to stop to oncoming traffic. I had to brake for maybe 10 seconds, and when I went to accelerate, it was like it wasn-€™t shifting, and it just revved up, rolled slightly, and would not go. At this point there are more cars coming. I am in the road right In their path due to it rolling, and once again I am put in a very scary situation. I kept trying, and it FINALLY went. This was also on flat level ground. I have had many moments (every day) where it does not shift properly, and it also stutters every single day when I start it. Please fix this

Warning light on dashboard board goes on and off constantly indicating rear brake light needs attention. When warning light is on, brake light does not work. When warning light turns off, brake light works. This happens when car is on and constantly at random times even when I'm stationary. Also, when I'm stopped, car tugs like it wants to accelerate.

Car was slowly entering garage and came to a full stop with brake pedal depressed in gear. Car without warning, engine revved up to full power and crashed in garage. I am alleging condition known as sudden unintended acceleration. I have had the damage repaired and the cost of repair was over $4,000. Pictures available upon request. Hyundai performed an inspection on vehicle upon my demand to do so. When report came in, I was refused a copy of exact report by inspector and only given a summary by company agent. When I asked for the exact inspector report to be read to me over the phone, that request was denied as well.

Car constantly hesitates when starting to accelerate. When you begin to accelerate from a stop, the car hesitates for several seconds before beginning to move. This is very dangerous when making turns at stop lights or in intersections. Going at highway speed the car runs fine and accelerates without issue. The problem is when at slow speeds or at a stop and you need to accelerate. Also, when going slow or slowing down to a stop, the car sees like it is going to stall and the engine/transmission begins to jerk as if it is about to stall. When driving through a parking lot at slow speeds with some quick on/off breaking, the car hesitates and feels like it is going to stall.
