2022 Hyundai Sonata Cruise Control Problems

Your car has experienced sudden, unintended acceleration on two separate occasions — once in June 2024 during a three-point turn (hitting a fire hydrant), and again recently while parking slowly at church (going over a parking block onto grass and sidewalk). In both cases, the acceleration happened immediately after you lifted your foot from the brake, causing significant damage. The issue appears to be a defect in the vehicle speed control system that occurs without warning.

Your car is experiencing unexpected acceleration at low speeds (around 20-25 mph) where the engine RPMs suddenly rev and the car accelerates on its own, then the brakes automatically engage. This has happened twice on residential roads and is particularly dangerous because it occurred when another vehicle was in front of you. The issue appears to involve a malfunction in either the cruise control system, engine management, or brake system that requires immediate diagnostic inspection at a dealership.

Your car keeps stalling or shutting off while driving, and the fuel injection system isn't working properly. This combination of issues is causing problems with engine performance and reliability. The fix will likely involve diagnosing the fuel injection system and addressing whatever is causing the engine to cut off unexpectedly.

In February 2024, on a day with snow on the ground no less, my husband was driving over the Verrazano Bridge from Brooklyn, NY to Staten Island, NY, when the car suddenly started shaking and the speed dropped from 50 to 20 in about 10-30seconds. The car started smoking and filling up with fuel fumes. Cars were beeping at him, almost crashing into the back of the car. He was able to make it to safety and had the car towed to the nearest Hyundai Dealership/service. The issue was an injector. On Saturday, [XXX], I got into the car with my two children (age [XXX] and [XXX] old). The car started shaking, all of the check engine lights flew on, the car quickly filled up with fumes, the exhaust was smoking, and the RPM Dial was dancing. I have never been so terrified. The car was towed and again the issue was diagnosed as an injector. Not the same one, a different one. I have been told by my local Hyundai that this is an ongoing issue and that Hyundai only changes 1 at a time, knowing that the others may be faulty. This is unacceptable. These cars need to be recalled immediately. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
