2024 Hyundai Tucson Engine Problems

Your 2024 Hyundai Tucson Hybrid is displaying a recurring engine warning light with fault code P0471, which the dealership has attempted to fix multiple times without success. You've also noticed the vehicle's mileage increased significantly while in the dealership's care, but this isn't documented in official service records. The dealership says they'll keep trying to repair it but hasn't offered a real solution or addressed your concerns about the unexplained mileage. Resolving this will likely require a thorough diagnostic scan of the exhaust pressure sensor system and possibly replacement of faulty sensors or related components.

Your car's engine began shaking and the tachometer dipped as you approached a traffic light, with the check engine light turning on; after restarting, the problem went away. A few days later, after an oil change attempt at a local shop, your car's entire computer system (radio, warning lights, climate control) stopped working, requiring the dealer to replace the engine control unit (CPU) to fix the issue.

Your car's tachometer dropped and the engine began shaking while driving, followed by the check engine light turning on. The dealership diagnosed the issue as faulty spark plugs and replaced them under warranty, which resolved the problem. The fix involved removing and installing new spark plugs.

Your car started shaking, shuddering, and almost stalled, with the check engine light coming on. This happened right after you picked it up from the dealership for the same issue the day before. The dealership diagnosed it as an EGR system problem and replaced some components to fix it.

Your 2024 Tucson hybrid experiences a 1-2 second delay before the engine responds when you press the gas pedal after coming to a stop, regardless of which driving mode you're in. This hesitation happens repeatedly and could be a safety concern when you need to accelerate quickly from a stop sign or intersection. The issue likely involves the hybrid system's transition between electric and gas power, and may require a software update or inspection of the fuel injection and hybrid control systems.
