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.

2012 Hyundai Accent 4dr sedan knocking in the engine compartment, engine light comes on and code is stored, the code is for knock sensor needing to be replaced...the true reason for this to put out code for knock sensor fauilare are that the connecting rod bearing is going out and that little bit of play between the rod and crank makes the knock sensor code come up it knocks moving or not this is a serious proublem the engine could have a serious engine failuare and at mid speed it can and will be life treating, fire, parts being thrown threw fire wall hitting occupants in car or outside it started the knocking at 130000 miles I am a mechanic of over 40 years

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.

Driving on the highway I heard a knocking in the engine. The check engine light came on. I took the vehicle to get the light checked for a code and was told the knock sensor needed replacing. Took the car to the dealer I purchased it from and dealer said there was no code and no history of a code so they could do nothing about it after I told them how to replicate the knocking. Dealer released the car. Two days later while driving on the highway the light came back on and the engine continued knocking. I took it straight to the dealer again and they were able to replicate the issue and find a code. The dealer contacted the manufacturer about the code and the manufacturer recommended applying a patch to the knock sensor and, according to the dealer "see what happens". the dealer performed the patch and released the vehicle to me. The very next day I was driving home after work on the highway and the odometer went from 3000rpm's to 0. while I could try to engage the accelerator and could hear the engine rev no rpms registered. The vehicle went into an idle state and would not react. Causing many near accidents I was able to get the car to the shoulder before it became stationary. Attempted to restart car a dozen times and the RPM's would not register still.car has now been with the dealer who has not been able to replicate the issue and has not reached out to the manufacturer. The cause and effect of an issue happening after applying a computer patch is not being investigated nor discussed with the manufacturer.

Takata recall I am at 130,000 miles and there is no oil leaking, but every time I get an oil change it just disappears. Even if I'm not driving 1000 mi/month, it is completely dry within a few weeks of getting an oil change. I have to constantly put oil in my car in between oil changes every 3 months.

On August 5th after a 20 minute drive my car was parked in a friends driveway. Moments after exiting the vehicle the engine caught fire. There were no previous issues. Smells. Warning lights. Drove just fine. Thanks to a passing off duty fireman he stopped and sprang into action with the garden hose until the fire dept arrived just moments later. Because the engine was one giant melted mess allstate was unable to determine the cause. There were no injuries. Hyundai showed no recalls after entering my VIN number. It was my third Hyundai and still shocked this happened.
