The contact owns a 2020 Hyundai Sonata. The contact stated that while driving at an undisclosed speed with the family inside the vehicle, a strong gasoline odor was inside the cabin of the vehicle. The contact stated that the fuel gauge was lowering quickly. Upon exiting the vehicle, the contact became aware of gasoline gushing heavily out of the vehicle onto the ground. Two months prior to the failure, the vehicle was taken to an authorized dealer due to an abnormal sound coming from the rear of the vehicle. The contact received notification of NHTSA Campaign Number: 25V796000 (Fuel System, Gasoline); however, the recall repair was not performed because the part for the recall repair was not yet available. The vehicle was towed to a dealer where it was determined that the gas valve was not properly fixed. The abnormal sound in the rear of the vehicle was due to the fuel expansion, which caused the tank to rupture and melt. The melting caused the fuel pump to expand and melt, causing s...

My 2020 Hyundai Sonata 2.5L is experiencing excessive engine oil consumption. At approximately 88,063 miles, Great Lakes Hyundai documented that the engine oil level was 1.30 quarts below full after an oil-consumption check. The dealer topped off the oil, submitted photos and a prior-authorization/goodwill request to Hyundai, and Hyundai declined assistance. The dealer recommended combustion chamber cleaning with an estimate of $979.76. I am concerned that this excessive oil consumption could lead to sudden engine damage, loss of power, stalling, or engine failure if the oil level drops between checks. The vehicle is only a 2020 model year, and this level of oil consumption appears abnormal. I am also concerned about possible emissions/catalytic converter damage from oil burning.

Hyundai Motors America has failed to comply with its statutory obligations in conducting the recall campaign 25V796, and is instead engaging in behavior substantially similar to that which has been previously censured by NHTSA. My Sonata suffered irreparable damage related to this campaign as confirmed by HMA. 49 U.S.C. ยง 30120(a)(1)(A) allows HMA to choose one of three remedies: repair, replacement, or refund. However, they 1) say it cannot be safely repaired, 2) will not replace it, and 3) are not offering a repurchase as required by statute, i.e. "by refunding the purchase price, less a reasonable allowance for depreciation." Instead, Hyundai's case manager Aditya informed me on 5/29/2026 at 12:57 PM that they will make a repurchase offer "based on the Kelly Blue Book value." I protested and cited the statute, but he maintained that Hyundai has their process and subsequently gave an unconscionably low offer that was not based on any reasonable measure of depreciation. I insisted...

For my vehicle the Check Engine light has been on continuously throughout the last 6 months and mechanics are going to have to replace the thermostat. Multiple auto mechanics have indicated online that this is a very common problem with many Hyundai vehicles from 2020-2023 and can be a danger due to temperature control not being accurate for vehicles (Code P2181). Many owners of these Hyundai vehicles have experienced this issue leading online and this issue should be made aware to Hyundai and the general public to see if this is something that needs to be made aware for the safety of drivers to determine if their vehicle is at an accurate temperature.
