Lag and than quick acceleration upon take off. RPM revs to2000, but power serge comes a few seconds later. Just bought this car, have not returned it for testing yet, but now understand Hyundai knows about this problem, but has no solution. Could be a hugh safety hazzard.

I have been reaching out to auto nation where I purchased my 2018 Hyundai Tucson while driving on the highway there was a swishing noise and sputtering the car just stopped I was however able to get on the off ramp the car was towed which cost me $528 to get out had he re-towed to an auto body shop and the engine rod blew out and up making a good size hole in the oil pan now I have to pay $120 diagnostics charges but they do not think Hyundai will pay for repairs so I'm paying for a car that is completely incapacitated. I was reading on your reports concerning Hyundai and Kia the law suit for their slow response but to this day I have not received any information regarding this problem your knowledge and report on the engine problem and rod is exactly what has happened to my Hyundai except it hasn't caught on fire as of yet my understanding is park it away from everything as just being parked it can still catch on fire. I need help on this matter... thank you I have been trying to get this resolved since March 2021

I was driving down the highway when I heard a very loud pop... I pulled over to inspect the car... the panoramic sun roof had shattered for no apparent reason.. no cars were in front of me or behind me... I saw no debris on the car or in the road... the road was paved.. I was really at a lost as to what could have happened to it.. until I started researching online and found out that it happens to these sunroof occasionally.. I am working with Hyundai now trying to get them to repair it... it really should be a recall...

Hyundai issued a recall with a replacement part needed to prevent an engine fire. When the dealership and corporate were contacted, was told they only have a remedy for the 2019-2021 and no remedy yet for the 2018 model, which is mine. Said they can't guarantee the car isn't dangerous and dealership told me to contact Consumer Affairs to open a case and see what they will do about replacing the car.

Ongoing issues with the engine transimission. After 3 dealership visits, problem was duplicated at bob mayberry Hyundai-monroe, nc. We were told this was a known problem and "fix/part" was coming in March/April 2020. I was never contacted. Continued to drive the car until finally got fed up with the same issue. I went to other dealership (keffer Hyundai-charlotte, nc.). was told they had to replicate but tech could not. (repair invoice states they drove the car 1 mile!) (the dealership was told this was an intermitent problem). The problem is when driving very slow in stop & go traffic, the car jumps similar to someone learning to drive a stick shift and have problems with the clutch. I was at a stop sign one day...at a complete stop. I proceeded to move forward and the car stopped about 3 feet after moving. Had I pulled out if there was alot of traffic, I would not have had time to move in the road. I do not have all invoices from first dealership (bob mayberry Hyundai-monroe, nc), but they will have everything in their system. I can request this documentation if needed.

On six different occassions my vehicle has stalled out while reaching speeds of up to 50mph. I have taken it back to the dealership on 3 separate occasions to be told there is nothing mechanically wrong with the vehicle. On 8/25/3020 it stalled again and caused me to be rear ended. I am terrified to operate this vehicle on public road ways now.

The 2018 Hyundai Tucson sel has an intermittent issue when accelerating from a stopped position. The engine will rev up, but idle forward for about 3-5 seconds, until the vehicle goes. This does not happen consistently. The dealership has reset the programming on the transmission 2X. There are other individuals online that are experiencing similar intermittent issues with their 2018 Hyundai Tucson. In June 2019, I was almost struck by a vehicle while I was completing a left hand turn on green when an oncoming vehicle decided to run the light. This has happened numerous times. On 10/7/19 - I brought it back to the dealership again to ride with a technician. During the 30 minutes ride, I felt like I had replicated the issue slightly but the mechanic only asked me what kind of car I previously drove. When I checked out of the dealership, I asked for paperwork to document my encounter, even if the mechanic claimed it was unfounded - but was not provided with any and told that there was nothing to document.

I have bought this vehicle last year. There is a loud noise when I take off after I have started the car and go. I have taken it in they told me it is the gear shifter. [xxx]. this car has no power when you take off and the brakes have squeaked since day 2.I have taken it in and they have scraped the brakes 3 times. I have complained and thought it was just me until I have read more complaints.
