43 MPG??

Orlando, FL, USA
What I Drive
2020 Ioniq
Here is my story.

My main reason for purchasing this car was it 55MPG highway rating and 54 MPG city rating. I paid $32,500 as I go the premium addition. I never expected to get 55/54 but be in at least 5% of the recommended mileage. My last 3 cars have all been Toyota Prius.

I have been averaging per tank 42 to 43 mpg. My issue is the Highway driving. Here is when I average the worst performance. The city driving is better for MPG and on short drives, keeping it under 45mph and staying off the break (Power Hybrid driving) You can achieve 50 to 55 mpg. But doing (Power Hybrid driving) for a full tank of gas under these conditions as much as possible I was only able to get 46mpg.

I went through the first tank on the day I purchased it. I stopped by my dealer within the next 2 or 3 days after purchasing the 2020 Hyundai Ioniq. I did not have a service visit I just wanted to make sure I was looking at the readings correctly on the vehicle. This is when they told me I would have to put 5000 miles on the car for it
to learn my driving habits and the MPG would improve. (I would have returned the vehicle that day if I were not told this as it has never improved.)

I have had several visits to my dealer to address this issue. After the second visit to my dealer they told me that there was nothing they could do and I would have to file a complaint with Hyundai Corporate. My dealer were doing the short in city drive and got 50mpg and 51 mpg on their test. my dealer refused taking my vehicle on a test on the highway.

After my first two visits and my documentation below, my case manager Pauline recommended a buy back. However, Hyundai Corporate did not approve as my vehicle had not been tested by someone from Corporate. This took five months to setup due to Hyundai COVID-19 policies. Hyundai has taken the vehicle on 4 test drives. Three test drives were done by Hyundai Central Florida. All three test drives were in the city and around 26 miles. They averaged 50 to 55 mpg. My dealer would not take the vehicle out for testing on the highway. The test drive by Corporate representative went out on the highway for 60+ miles. His report on that trip was 41.9mpg. I was able to speak to him after his test drive. He filled the tank before his test drive and filled it again when he was done. He was also the corporate representative that was required by Hyundai Corporate.

This information is also documented in the paperwork at my dealer, but they would not provide me a copy. Hyundai Corporate and my case manager Pauline both recommended a buy back. Hyundai Corporate did not approve the buyback. They only provided me with a log information that was done in city on a 27.2 mile drive. They ignored
the issue with Highway driving and still will not address the issue. This is why I have opened a case with the Better Business Bureau for 3rd party representation.

Has anyone else had these issues? My last Prius I would drive it as a normal car and still get 48 something a gallon. And If I hyper drove the car I could get 55. Hyper driving my Ioniq on long distances I have only been able to achieve 46.
