I respectfully submit the following additional information.In connection with this matter, the dealer in question asserted in writing that I "should have refused to participate" in the manufacturer-authorized "Z05 Service Campaign"—a measure designed to prevent potential damage—and characterized the program as nothing more than "free paint work." Service campaigns administered by manufacturers are conducted within the framework of federal safety regulations pursuant to Title 49, Chapter 301 of the U.S. Code; they are neither optional nor merely cosmetic in nature. Rather, they constitute systematic procedures intended to preserve vehicle integrity and support public safety. Statements suggesting that consumers should decline participation in such campaigns—or that they may bear financial responsibility for damage incurred during their execution—raise concerns regarding how these federally supervised programs are communicated and implemented and may discourage participation and undermine public confidence in the national vehicle safety campaign system. Although the dealership subsequently offered to replace the windshield at no cost, I have not received confirmation that the repair has been completed. This offer was made only after the vehicle remained at the facility for an extended period, during which I was repeatedly placed under pressure to assume financial responsibility for damage that occurred while the vehicle was under dealership custody. I was presented with two conditional options; however, in either scenario, I would ultimately be required to accept financial responsibility for the outcome. Ultimately, I was required to assume financial responsibility for issues arising during the work. On 2/23, I was told the loaner could be reported as "stolen," and I returned it immediately. After returning the vehicle, no alternative transportation was provided while my own vehicle remained unrepaired.

Starting in July 2023 I have noticed that the oil consumption for my car is racing through the engine. I barely make it 1000 miles before the oil is completely gone. After 2 local oil changes - I decided to take it to the Hyundai dealer where I purchased the car. This was in October - I have brought my car in 4 times for 1000 mile oil consumption tests. I had to add an additional visit due to the fact that Hyundai changed the testing standards. Now I have to bring it again today - Hyundai has not told me what the next step is other than I have to leave the car there all day - after they speak to tech support they will determine next steps. Most likely a combustion cleaning. Then I have to start the 1000 mile consumption tests again. I live 35 mins from the dealer - I have had to hire someone to take me there to leave car - and I then have to take mass transit to work. There are never any loaners because they are booked months in advance. I have had to rent numerous cars for long distance travel due to the mileage meter of 1000 miles on my car - I am not allowed to go over - if I do have to start all over again. That happened to me the first time. My car is crap at this point - I am not able to use it as I should be able to and Hyundai is giving us the run around. I have been contacted about trading it in and getting a new Hyundai - what a scam. I am not the only person - there are so many of us - follow the chats on Facebook and Reddit - nobody is helping us. The staff said if your engine seizes - that would be great. People are seizing on highways - that is very scary to me. Why is this not recalled yet?

This vehicle was bought brand new from West Broad Hyundai in Richmond , VA. I was financing this vehicle had it for almost two years before it was stolen. The police said it was a couple of teenagers. I lost thousands of dollars almost 2 years worth of car payments. I think Hyundai should be accountable because they nevar notified me these vehicles were easily stolen. I lost two years of car payments. I still owe 1,000 to Capital One because my insurance company didn’t fully payoff this loan. Please help: I lost allot of money had to come up with a down payment for a 2019 Hyundai Tucson. This vehicle has the same problem with it can be easily stolen. My information is Mary Chanberlain 6700 Veritas Way 1-B N Chesterfield 23234 804-2411844

Unknown. This has happened a couple times now. I am driving and the HEV light, engine light and battery light turn on, car won’t brake properly and almost cause me to hit other cars and will shut off on its own on the highway. It will accelerate on its own even when trying to brake. Extremely dangerous.
