2016 Hyundai Sonata — Known Issues & Recalls

Your engine seized (locked up) without any warning lights or messages, causing your car to suddenly stop while driving in traffic. Both a dealership and independent mechanic confirmed the engine has failed and needs repair or replacement. The manufacturer has also inspected the vehicle. Fixing this will require the engine to be rebuilt or replaced entirely.

Your engine has seized, meaning it has stopped working and the internal parts are locked up. This is a critical mechanical failure that will prevent your car from running at all. Your engine will need to be rebuilt or replaced entirely.

Your car has been burning oil, and your engine started making a knocking noise without any warning lights appearing on the dashboard. After taking it to a mechanic, the engine was found to have failed completely, even though your car has less than 130,000 miles. The mechanic will likely need to rebuild or replace the entire engine to fix this issue.

While driving in normal traffic, the engine experienced a sudden and significant loss of power and went into a reduced-power “limp” mode. The check engine light illuminated and the vehicle stored an active P1326 diagnostic trouble code related to the engine/Knock Sensor Detection System (KSDS).

I took my car in for an oil change and the tech wouldn’t even take my money because he said the car was a safety issue and it needed to be taken to a hyundai dealership ASAP as he has seen the engine fail or blow up on this model before. on the way to the dealer the engine completely seized in the middle of the road forcing us to stop traffic on the busy road and push it in a near by parking lot.

Engine failure, cylinder 4 is swimming on oil.

Your car won't accelerate past about 60 mph, even when you press the gas pedal all the way down. When you try to speed up, the engine RPM jumps up and then drops repeatedly, causing the car to struggle and lose power. This happens consistently during normal driving and makes it dangerous when you need to merge on highways or accelerate in traffic.

My 2016 Hyundai Sonata (2.0T/2.4L engine) has been experiencing loss of motive power and severe engine stumbling at stoplights, creating an unreasonable risk of a crash in traffic. The Check Engine light is on with DTC P0010. Upon inspection, the internal oil seal plug at the intake camshaft E-CVVT has become unseated, causing an active oil leak.

Vehicle started then stalled requiring tow. No initial illumination of warning lamps or messages. Findings upon inspection by independent service center: multiple cylinder misfires (P030100, P030300, P030400, P030200, P030000) and excessive debris buildup on vvt sensor screen.

Your engine is throwing a diagnostic code P1326, which is causing your car to stay stuck in first gear and preventing normal acceleration. You're also hearing knocking noises from the engine area, and the check engine light is blinking. If this issue isn't fixed, your engine could stall out or lock up completely while driving. This will likely require engine diagnostics and repair of the underlying mechanical problem causing the code.

Your 2016 Sonata has multiple warning signs: the ABS light is on, your car won't go faster than 60 mph, and the check engine light is blinking. You're also experiencing engine stalling and problems with the VVT sprocket. Hyundai has only offered a recall for the junction box, but you believe the issues match known engine and oil pump problems affecting this model year. The repairs will likely require a full engine diagnostic, inspection of the oil pump and rod bearings, and possible replacement of the VVT components or engine work.

I began braking and the brakes locked up. Braking to the floor and the car would not stop resulting in a car crash

I was involved in a low-speed collision at a residential intersection after stopping at a stop sign and beginning to proceed. Going under 5 MPH, I braked immediately, but contact occurred. Despite relatively minor front-end damage, the driver steering wheel airbag and driver knee airbag deployed.

The driver’s seat / passenger seat assembly, including seat rails, mounting brackets, and Smart Junction Box (SJB) connections if electrical adjustment was involved, completely failed during a crash.

Vehicle: 2016 Hyundai Sonata VIN: [XXX] While stopped in traffic with my foot firmly on the brake, my vehicle begins to accelerate before I release the brake pedal. This is not normal “creep” — the engine increases RPM and the vehicle moves forward as if the accelerator is being applied, even though it is not. This condition has occurred multiple times and creates a serious safety risk.

Your car is leaking oil from the top of the engine, which causes a burning smell inside the cabin and an unusual noise from under the hood. This has happened multiple times, but your dealer couldn't identify the problem. An independent mechanic confirmed that oil is being blown out from the engine's top. Fixing this typically involves replacing the valve cover gasket or other seals that are allowing oil to escape.

Both rear doors on your car won't open because the door locks have stopped working. Additionally, the right rear door window won't roll up or down. This leaves your rear doors inaccessible and the window stuck in its current position.

The contact owns a 2016 Hyundai Sonata. The contact stated that while driving and depressing the accelerator pedal, the vehicle failed to respond or exceed 30 MPH. The contact stated that the speedometer reading was lagging.

This vehicle has experienced multiple hybrid system failures while driving, including a complete loss of power “Hybrid System Warning – Turn Engine Off” on the interstate in June 2022 through November 2025. These events have placed me and my loved ones in dangerous driving situations.

Engine started rough idling and knocking. Took to a mechanic who found metal particulate in the oil and the engine spun a bearing.
