Purchaseing the vehicle two months ago, the engine service light started blinking. Taking the vehicle to several shops including two hyundai dealers, I was informed the vehicle had an off market catalytic converter. I asked the dealership several times if there was any issues with the vehicle and they stated there was not. The engine first came on two weeks after the purchase of the vehicle. It is not safe to drive.The warranty nor the dealership will cover or assist.

Acceleration issue, from a stop position on a red light or stop sign, when the gas pedal is pressed the engine revs but does not move immediately, after a couple of seconds it lundges forward, also when trying to merge you must wait for a very big gap to safely merge, the car does not respond and this is very dangerous, Hyundai need to rectify this issue before someone dies.

When driving at night and low-beams are on, there is a black void (looks like a black bar horizontally across the headlight projected area on roadway). Black void is eye level with driver-??s view of the roadway. With the black void present, driver is unable to see the roadway clearly at night, which inhibits the drivers visibility and ability to see road hazards or animals crossing the road. Low-beam and high-beam bulbs have been replaced and checked for any burn spots or malfunction in the bulb itself; with brand new bulbs installed professionally, the black void is still present. Hyundai repair stated it is a known issue that has yet to be addressed by Hyundai Manufacturers. Issue has been present for 2-months now. While driving on interstate, went to pass a vehicle and while accelerating the vehicle would not increase in speed. The RPM needle jumped to 5-6 and a -??whiny-?? noise was coming from engine area. Pressed harder on the accelerator so the car would speed up and with the pedal to the floor, the vehicle speed increased 1 mph in 5-sec intervals. Exited the interstate and was traveling on road with 60mph speed limit. Tried to accelerate again, and the vehicle would make the whiny noise and would not increase speed or shift. Let off of the accelerator and the RPM drops instantly to 2-3. RPM-??s need does not smoothly increase or decrease, but instead jumps or drops instantly. When accelerator is pressed or when trying to increase speed, the whiny noise comes from engine. The vehicle sounds and acts like it is not shifting. Took to dealership and they said there are no recalls on transmission, but will not fix my transmission. 10-year/100000 mile warranty is still active, as it is a 2018 w/ 89500 miles. Safety concern as the vehicle will not accelerate or shift when needed and could cause serious accident if in a situation where evasive action is required.

Leaving a parking lot, vehicle was hard-shifting at 10mph, 20mph, 30mph and was not gaining typical acceleration. Every slow down or stop sign/stop light this behavior continued with automatic hard shifting between gears and lethargic acceleration to the point where I felt this may cause an accident or cause another vehicle to have an accident due to lag response of my vehicle. Upon home arrival, I attempted to back vehicle into my parking spot but after shifting into Reverse, the R indicator on console was flashing but vehicle would not move. I drove back around the complex parking circle and again attempted to back vehicle in to a different parking space but experienced the same issue where R indicator was flashing but vehicle would not back up. My daughter and 2 grandsons then had to push my vehicle back in to the parking spot. I turned vehicle off, waited approximately 90 seconds and restarted the engine. When I shifted into Reverse gear, the car abruptly and harshly shut down. At that point, I put the vehicle back into Park gear and turned off ignition. Had the vehicle towed to closest dealership on Nov 28th - they have not been able to replicate issue nor find any fault codes when running diagnostics. No dashboard errors appeared, only the flashing Reverse indicator light on shift console. No prior issues earlier in the day when using vehicle, nor has this issue occurred in the 4 years I have owned it. It was severe enough I wasn't sure the vehicle would clear intersections in a timely manner, and worried it may leave myself and my daughter and grandsons stranded on the 20 minute ride to home.

Vehicle stalls when accelerating at low speeds. It appears to be a delay when the car transitions from 1st to 2nd gear. This creates a safety concern, especially when taking turns into traffic due to delays/stalls when turning.

- Vernon Hills, IL, USA

I-??ve been having an issue with the car -??jerking rapidly-?? when in traffic and rolling slowly and when climbing relatively small hills, it began about 2 months ago but have become progressively worse over the last month. I was told by someone with a similar vehicle that it is the -??lower arm control. Need help with is or if there is a recall

While driving my car normally 9 dashboard lights came on suddenly including the check engine, ABS, brakes while at the same time the dials on the dashboard including the rpms, speedometer, oil temperature and more all stopped working. This happened suddenly while the car was in drive and also caused issues with the transmission as the car stopped shifting gears properly and was driving very rough. With this sudden onset of many different issues out of nowhere driving the vehicle was very dangerous when trying to get to a safe location. After parking this electrical issue would not allow me to take the car out of park or use a OBD reader do to the electrical issue. After researching this problem I found several reports online describing nearly identical symptoms all of the sudden resulting in the car being undrivable and in a dangerous state. These owners said they took the cars to the dealer who tried replacing several components without fixing the issue with hours of diagnosis charges. Eventually after having the vehicles for several days they replaced the reverse camera which it turns out was shorting a significant amount of other critical car electrical components. With no prior damage to the camera or these electrical components the abrupt and random onset of this issue pose a significant safety risk to Hyundai Tucson drivers (at least in 2016 -2018 models). My experience with the Hyundai Dealership was very similar to them even after I had diagnosed the issue to the camera the dealer said they had contacted the manufacturing engineers who took several days to determine what was causing these electrical issues. This is not an isolated issue as multiple hyundai tucson owners have reported this to Hyundai and their dealerships yet they fail to recognize the risks associated with the faulty cameras they install in their factories. They need to recall their vehicles prone to having this issue. This has cost me $1000 to fix and put me at risk on the road

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?

- Alexandria, VA, USA

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.

- Landaff, NH, USA

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.

- Ormond Beach, FL, USA

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.

- Port Saint Lucie, FL, USA

very bad acceleration from a stop position, engine revs but does not move, in slow traffic it hesitates and lunges forward like it-??s not sure what it-??s suppose to do, when trying to merge or pass another car, you have to give yourself time, it-??s very dangerous, took it to the dealer 2 times, was told that-??s how the car is made, there is no way this is suppose to be the way the car was built. also a smell of antifreeze but no leaks detected,

- Ormond Beach, FL, USA

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 -??cannot replicate-??. This car is going to kill me.

- Apex, NC, USA

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.

- Plain City, OH, USA

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

Vehicle has judder at slow speeds or hesitation in shifting gears. Has almost stalled while making a left turn at intersection into oncoming traffic or accelerating after stop sign. Dealer updated TCU ECM software, problem got worse. Appears to be a dual clutch transmission defect.

- Miami, FL, USA
