Had oil changed at Take 5 recently as always do. 2 weeks later car cut off 3 times in traffic. Engine light came on. Car started to lose power/acceleration and engine began to make a ticking/knocking sound. I checked the oil and none was in it. I added 4 quarts to see would that help. It did not.

The 2011 Hyundai Elantra false starts. I-€™ve changed the battery and gotten a tune up. I-€™ve taken it into the dealership and paid for a diagnostic, even the Hyundai dealership says they cannot explain why the car is false starting. I believe it is my engine. But why isn-€™t my car Included in the engine recall?

My car stalls while in motion without warning. While driving the vehicle will randomly speed up and rpm will fly up without command. I also experience a lot of engine power loss randomly the vehicle will bog and be slow. Occasionally when I press on the accelerator I can almost go to the floor with no response from the vehicle. Speed acceleration response is delayed approximately 30 seconds occasionally. Uncommanded acceleration and random stalling when vehicle is in motion has been a big safety risk for me. This issue has been ongoing for awhile. This issue has occurred countless times so it-€™s very frequent. This complaint is in compliance with the current open investigation regarding the throttle control system vulnerabilities. NHTSA Action Number: DP21003

The battery won't charge and causing the remotes to keep going out and I'm unable to start my car with the push start remote. The battery and remotes were just replaced in November 2020 & it is now giving me the same issues again. I came back to start my parked car & it won't start.

Engine has trouble starting or stalls often. Was told to replace whole engine when I went in awhile ago due to issue of starting, noise and oil leak. TPMS sensor I think is shot to every time I fill up air it still suggests issue with tires. Windows also get stuck down or up.

When going at low speeds in traffic car shuts off after pressing break too much. Car shuts off in reverse. Car shuts off while making turns and hitting break simultaneously. Going over 60 mph causes car to shut off multiple times every few minutes or even seconds. (worst was 9 times in under 2 minutes) car shuts off slowing down to red light. Had car checked numerous times by mechanics. Noone can figure it out. No code comes up when plugged into computer at autoshop. Alot of other people have reported this issue with same make and model

My daily driver began to make a knocking noise and my dashboard break light indicator came on. I immediately scheduled service with my Hyundai dealer. But it did not make the (2) days wait. While driving at highway speed the front end began to intermittently pull to the right as if the right front brake was being tapped independently. Within minutes all of the electrical shut off and the engine stalled. I drifted to the side of the road. After several attempts the electrical did come back on but the engine would not turn over. I had the vehicle towed to closest Hyundai dealer, who said the engine needed to be replaced and all that was available was a used engine with 60,000 miles on it at an approximate cost of $5,000 dollars with no guarantee that it may require additional repairs.

There was total engine failure when the car reached about 80K miles. This is known for in the 2011 Hyundai Elantras but hyundia has yet to recall the Elantras just the sonatas. Despite constant and frequent oil changes oil sludge formed and entered the engine compartment completely rendering it unrepairable. A "new" engine had to be placed but I was warned the problem could occur again but a recall still has not been issued. This is dangerous as the engine was sputting out, misfiring and blue smoke was being released from the exhaust due to this

My car has had engine light on over one year since I bought it used, different shop tried to fix it but they can't get it, they said it is because of vehicle bad system itself so why it shakes every single time, electrical power system is not good, the heating system was down, the fixed it a couple days from now but still it isn't working properly.the problem came in when I was driving in highway I-295 Maine state.

I was told that metal shavings were found in the engine block and they also covered my camshaft position sensor. The metal shavings lead to the pistons not getting enough oil and it threw a rod, as a result of these medal shavings and little oil viscosity. The car was in motion, on the highway.
