Since at least November 14, 2016, HYUNDAI and its authorized repair facilities knew or should have known the TCM and DCT in its vehicles were susceptible to software issues causing drivability problems at low speeds. Since at least December 2015, Hyundai was aware of the TCM and DCT defects based on consumer complaints made online and to its authorized repair facilities and dealers. Since at least 2015, through consumer complaints and dealership repair orders, among other internal sources, Hyundai knew or should have known that the DCT and DCT contained a defect that diminishes the drivability of DCT-equipped vehicles and creates safety hazards.

For example, the TCM Defect makes it difficult to accelerate safely from traffic stops because the vehicle will hesitate, fail to shift gears, and stall when drivers depress the gas pedal to gain speed. These conditions substantially impair the driver’s ability to control the vehicle during normal operation and prevent drivers from accelerating safely to maintain safe speeds in traffic. The defects cause dangerous and unsafe conditions, including failing to shift, stalling and delayed or unresponsive acceleration, especially from a stop. These miscalculations result in an unresponsive accelerator pedal, delayed or no acceleration, jerking, shuddering, shaking, and stalling. The TCM misinterprets data from the vehicle’s sensors, thereby miscalculating both the appropriate gear and the correct shift timing. Designed to “provide an improvement in fuel consumption and CO2 emission compared to a conventional six-gear automated transmission, while acceleration performance increases,” the DCT features two dry clutches that transfer engine power “independently into the off and even gear train to always be ready to shift into the next gear.” The TCM is a small electronic component within the powertrain that processes data from various sensors throughout the engine in order to determine the optimal gear for shifting and fuel-economy. Hyundai knew that “ne of the most important issues was to know the temperature of the clutch lining to prevent system failure at high temperature” so “a precise clutch temperature model was developed, and validated through rig and vehicle tests simulating a large number of different driving conditions” including “high speed at German Autobahn, heavy traffic jam in Seoul, long distance cruise in the USA, high temperature in Middle East, cold conditions in Eastern Europe as well as high humidity and rough road in China.” Hyundai premiered the DCT in October 2014. Hyundai began development of its new DCT in 2011: “The design phase was started in early 2011, and the mass production started in September 2014 at the Hyundai-Dymos plant located in South Korea.” Hyundai learned of the TCM Defect during this period. If you have brought your vehicle to the dealer at least two times, and the dealer has not been able to repair the problem, duplicate the problem, or you have been told there is nothing wrong with your Hyundai, you may be entitled to a buyback or repurchase under the California Lemon Law. If you purchased or leased one of the following cars or SUVs:Īnd have experienced any of these problems, you may have a lemon under California’s Lemon law. The TCM and DCT defects causes, among other problems, unresponsive accelerator pedal, delayed or no acceleration, jerking, shuddering, shaking, failure to shift, stalling, and/or loss of power. Model years 20 Hyundai Elantra Eco, Sonata Eco, Tucson, and Veloster Turbo have defects in the transmission control module (TCM) and the 7 speed dual clutch automatic transmission (DCT) that impair your use, value, and safety.
