EXTERIOR LIGHTING, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving the dashboard headlights and all safety systems shut off for a brief period and then reset and if driving at night this leaves you completely in the dark till the system resets. All lights exterior and interior all the safety sensors, adaptive cruise control everything shuts off. Anything tied to the electrical system shuts off. The only thing that remains running is the engine.

POWER TRAIN
At least 8 times when driving the car the transmission switches from the drive “d” position to the park “p” position and I have to cut off the car and then restart. It is very dangerous as I can be rear ended which can result in personal injury as well as an insurance claim. I’ll put the last date it occurred but started experiencing soon after I bought car.

ENGINE, UNKNOWN OR OTHER
My 2012 Hyundai Sonata recently had an engine replacement completed under a Hyundai recall. Immediately after the recall repair, the vehicle began shaking while driving, produced a burning smell, and the air conditioning stopped working, none of which occurred prior to the recall repair. These symptoms started immediately after the engine replacement, indicating a possible improper or unsafe installation. I believe the vehicle is unsafe to drive due to the burning smell and shaking. I contacted Hyundai Customer Service and was told the issue must be resolved with the dealership. However, the dealership has refused timely inspection, has dismissed my safety concerns, and has declined to provide a rental or loaner vehicle, leaving me without safe transportation. This is a post-recall safety issue, and I am concerned about the risk of fire or mechanical failure due to the burning smell and vehicle instability. I am requesting this issue be formally investigated.

ENGINE
While driving the vehicle, I repeatedly must check and put oil in. (On average once per week) I took the car to an auto shop where I was told that the engine was bad and I must get a new one. I kept driving, putting oil in as needed, then the car in the middle of driving started to shudder and the check engine light came on. I parked the car and haven't driven it since

ENGINE
My car stayed with up to date oil changes and everything. One day I noticed it was leaking oil and had to stay on top of adding oil. When took to a mechanic they said my motor was blown and needed a new one. I took very good care of this car and it’s crazy that I need a new motor after babying the car.

ENGINE
On January 21, 2026, while driving on I-495 at highway speeds (e.g. 50-60 mph) in heavy traffic, my car made a "clunk" sound and I suddently was unable to accelerate. There were no warning lamps, messages, or other symptoms prior to the failure, but immediately when it happened several warning indicators, including the check engine light, oil light, and tire pressure indicator, lit up. The electrical systems and brakes appeared to still work, but the best I could to was coast onto the nearest shoulder and call for an emergency tow. I waited on the shoulder of a busy highway, in the dark, for over an hour. My car apparently has a type of engine that is known for catastrophic failure, so I assume that is what happened. I had the car towed to a Hyundai dealership and they confirmed that the engine needs to be fully replaced.

FUEL/PROPULSION SYSTEM, POWER TRAIN, ENGINE
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. This matches the exact defect and symptoms (elevated idle of 1,200–1,400 RPM and power reduction) described in Hyundai Service Campaign TX3 (TSB 15-01-022-1). While that campaign only applied to 2015 models, my 2016 vehicle has suffered the identical failure. I am requesting that this safety-related defect be investigated for 2016 models to prevent potential engine fires from oil leaks or accidents from sudden power loss

The oil in the car burns quickly. After driving 2000 miles, there is no oil left. I do not have any oil leaks anywhere. It’s just burning oil. This has been consistent since I’ve gotten the vehicle.
