“After starting my car there is a strong smell of gasoline, at different times, but not consistently. The smell of gas is very strong in the cabin area even while driving. Sometimes, once the vehicle has been started there is a strong smell of fuel coming from the exhaust pipe area. I have reported this to the dealership, was told nothing was found, per camelback Hyundai dealership in phoenix arizona (12/29/20).”

Both vehicles act the same,hesitate when they want to. Both have done this since brand new and neither dealership has made an effort to fix the problem. There has been several very close calls hesitating like this in heavy city traffic.also be on the lookout for a lawsuit settlement on 2018 Tucson.”
NHTSA complaint #11325437, filed 2020-05, 75 miles“Around 1500 ,iles the car started to either stall completely or jump forward in al drivemodes, took to dealership , they said it has to do with transmission being essentially a standard. They told us they reset the computer and it needs this occasionally. Really never heard of that. Our gasmileage is also constanlty going down. Not happy with the constant sudden accelertion especially when merging onto interstates. Bought this thing brand new feb 2018.”

On January 24, after driving for about 15mins, my check engine light began flashing. The car would not accelerate over 25mph. I brought it to a dealership where it has been for 3 days. All communication about this problem was initiated by me, and the only answers I get are vague comments about testing.”
