My Hyundai Sonata has encounter two failing cylinders (compression loss) due to scoring. When driving in the highway I got engine shudder and loss of power (speed) that could have put me in dangerous driving condition, accident or other. These GDI engines are notorious for poor oil circulation due to faulty designed piston rings. Hyundai has long history with these poorly manufactured engines and class action lawsuits. I notified Hyundai but they are not willing to remedy the situation. I have worked with local dealership Miller Hyundai, as well as corporate. All I get are excuses and that I’m not covered. These engines are completely problematic with oil consumption and oil blow by, causing seizing, rod bearing failure, carbon buildup, cylinder damage, etc. The info on the internet over customers and these GDI engines is overwhelming. Oil related Fires are another issue as well. Hyundai needs more accountability than the class action for rod baring failures. Because of the damage

I am reporting a safety-related engine failure involving my 2011 Hyundai Sonata 2.0T. In November 2025, at approximately 90,000 miles, the vehicle experienced a sudden engine failure while driving, including loss of power and abnormal engine noise. This created an unsafe driving condition and required the vehicle to be removed from service. Component/System Involved: The engine (Theta II 2.0T) suffered a catastrophic internal failure. The engine and internal components remain available for inspection upon request. Safety Risk: The sudden loss of engine power reduced my ability to maintain speed and maneuver in traffic, posing a safety risk to myself and other motorists. Confirmation and Inspection: The failure was confirmed by an authorized Hyundai dealership, which inspected the vehicle and documented the internal valve train condition through photographs. Hyundai Motor America reviewed the claim and issued a written denial. No independent third-party technical inspection was perf

The Vehicle: "I have a 2011–2014 Hyundai Sonata with massive underbody rust." The Failed Fix: "Service Campaign 946 was completed on this car in 2017, but it did not work. The rust is now worse." The Safety Risk: "The structural metal is so rusty that I am afraid it will snap while I am driving. This makes the car unsafe." Hyundai is refusing to fix it because the car has a 'branded' (abandoned) title, even though the structural safety issue is still there."

The vehicle experiences a recurring defect where the brake light turns on suddenly and the engine shuts off while driving. The failure appears related to the braking system (brake switch circuit), electrical system (CAN-bus/ECU communication), and engine control (shutdown/stall). The system remains installed and is available for inspection upon request. The shutdown poses a serious safety risk, including possible rear-end collision or loss of power in traffic. The problem has occurred multiple times. The dealership inspected the vehicle briefly but failed to diagnose or document the defect and returned the vehicle within hours, stating “it shouldn’t be a problem,” even though the issue continues. Hyundai has refused to provide recall documentation or authorize a re-inspection. The only warnings prior to shutoff are the sudden activation of the brake warning light just before the engine cuts off.

While driving home from work after 7 PM on the 215 NB freeway, the oil warning light suddenly illuminated, and the vehicle immediately lost engine power. Within seconds, the engine shut off completely, leaving me unable to accelerate or safely maneuver. I was forced to coast across lanes with no power, creating a significant risk of collision and nearly resulting in a rear-end accident. After the incident, I performed a crankshaft rotation test, which the engine failed, confirming that the crankshaft would not turn. I also verified that the timing chain remained intact. The vehicle has since been inspected by Hyundai technicians, who confirmed the engine failure under Service Campaign 953. Hyundai further communicated via email that my vehicle is eligible under the TXXI Theta Engine Settlement Agreement and expressed a willingness to discuss my recent engine concerns and the details of the settlement.
