2020 Hyundai Tucson Complaints

The engine lost power while driving, and the vehicle entered a reduced-power mode. The check engine light began flashing, and the engine made a loud knocking noise during acceleration. A diagnostic scan showed code P1326 (Knock Sensor Signal Range/Performance). The knock sensor was replaced, and the engine oil was refilled after discovering an oil leak. The vehicle operated normally for a short time, but the same symptoms returned. The vehicle is available for inspection. The vehicle suddenly lost power while traveling approximately 70 mph on the highway, making it difficult to maintain speed and safely keep up with traffic.

A diagnostic scanner consistently identified code P1326. The knock sensor was replaced and the engine oil was replenished, but the same symptoms returned after several trips. The vehicle...

High excessive oil consumption and premature piston ring failure leading to excessive oil consumption

Tried passing someone on the thruway, as I was about to the car jerked a bit then started decelerating. The check engine light started flashing and so did the oil light. Read the code as cylinder 3 misfire and a knock sensor. Changed the spark plugs and coil packs then checked the oil and saw there was no oil in the engine. Was told by my mechanic it’s a common problem with these Hyundai engines, it seems the rings are getting fried in the engine and that’s why it consumes oil so quickly.

While driving on the highway with adaptive cruise control on, car began decelerating without any vehicle in front. Started to get off highway, check engine light began flashing and came to a full stop. Car died. Tried restarting and car died. Check engine, oil and battery lights then on. Total engine failure and no warning lights prior.

Was in a side impact car accident last year. And have been speaking with Hyundai off and on since the accident and have basically been brushed off in my concerns about the fact my airbags never deployed when my rear passenger door was essentially ripped off during the car accident. Progressive moved quickly with my claim and Hyundai pretty much told me not their problem since progressive moved the vehicle so fast and they said they can’t locate it even though I gave them exactly who to get in contact with and they never bothered and basically told me my issue was unfounded due to the fact they couldn’t locate said vehicle
