2012 Hyundai Accent Engine problems

While traveling at highway speeds on [[redacted]] with three passengers, the vehicle suddenly suffered a catastrophic internal engine failure (severe rod knock), forcing an emergency deceleration in active traffic that put all occupants at risk of a rear-end collision. The sudden breakdown was immediately preceded by a flashing Check Engine Light and violent metallic knocking, despite the vehicle being regularly serviced and having a Knock Sensor Detection System (KSDS) software update completed just one month...

Unknown. I think the abs module light appeared instantly on the dashboard. It's the anti-lock brakes that aren't working. I immediately contacted my hyundai dealership when I saw a brake light come up on my dashboard when I went to brake but I had none and the brakes went all the way to the floor and I almost went over a cliff and died or badly hurt others or myself in a car accident. I'm willing to try and get it fixed at other independent service centers in plymouth massachusetts. The event had happened a week...

On the [[redacted]], my 2012 Hyundai Accent caught fire in the engine compartment and engulfed in flames. Right before the fire started, smoke came out of the air vents into the car, causing me to become stifled and choke for several minutes. Smoke was also coming out of the hood. At that point, I lifted the hood and there were flames coming out of the engine.

Didn't change the ticking. At 120k tick became a loud knock, after new oil/filter...

Loud ticking and engine knocking. Car starts to stall and overheat, car does not shift properly. Was told it was failing coils. Replaced all coils and spark plugs, this remedied the flashing ck engine light. Check engine light still on and still says the coil is not responding. Tech says it is a stuck lifter but can't be manually unstuck. Road hazard is car will stall and engine will fail without warning. Car has received regular oil change maintenance.

When the car stops at a stop sign or traffic light the engine sometimes stalls and the engine and EPS warning light turn on. Also sometimes when trying to accelerate, acceleration is not possible, especially on the highway. This is a major safety risk of rear-end accidents.

Car turns off while driving continuesly misfires even after replacing coils and spark plugs check engine light on and flashes car charger port keeps blowing fuses

The engine just stopped while driving. It was determined that the connecting rod broke and failed on the number one piston. Pieces of metal caused the crankshaft to lock up and pieces pierced the block causing complete engine failure. The connecting rod was cast wrong and it seems after the car has 100k miles it gives out. To me this is a safety hazard. *Tr
