Engine Knocking Noise problems of the 2013 Hyundai Elantra

My vehicle had been parked in my driveway and when I went to start the car it wouldn't start, but it began making this knocking noise. I had no idea what caused this, but it was extremely embarrassing and the only thing I could think of was to disconnect the battery. And that's when I heard the noise coming from the engine.

A ticking/knocking noise is going on in the engine, powertrain. It's been happening since I bought the vehicle and is worse in cold weather. It is believed to be a valve train issue. The knocking gets worse when I accelerate, also. This appears to be a known problem with 2013 Hyundai Elantras, but there isn't a recall for the engine. I contacted Hyundai and they've been slow to respond. My vehicle is currently with the business that I bought it from. They're using the quick, temporary warranty to get a new used engine, but I'm concerned that the same ticking/knocking noise will occur with the new used engine, because they refuse to use a different brand engine. I'd prefer that Hyundai do a straight up recall for the engines that consistently perform this way - with a knocking noise that hinders the performance of the vehicle.

The vehicle has a strange sound when started up in the mornings. Almost like a ticking or small knocking sound. When I put my car in reverse to back up it starts to jerk like it's about to shut off. Also that same jerking occurs while driving on the highway. When my car is at the speed 35 it starts to jerk like it's about to shut off too. It happens all day long between the speeds 35 to 65. When I turn on the ac my car makes a weird squeaking nose and also jerks like it's about to give out again. I have had all my fluids check and everything is just fine. I dont feel safe in my car. It started happening the same day I got my vehicle from a small used car lot on March 4th 2019. It's been happening since the day I have left. I called the guy who sold my the car and he told me t was probably the gas being bad since the car sit so long on the lot. But it has never stopped.

Engine making ticking & knocking sounds.

A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. In motion the knocking comes from the engine and when stopped it hesitation and vibrate.

My car started developing a ticking/knocking noise from the engine at startup- specially cold startup. The noise seems to go away after the engine is sufficiently warmed up- like driving 5-6 minutes on cold days and a minute on warm ones. Recently, I have started experiencing shudders in the drivetrain-- these feel like sudden motions, like the engine is trying to stall. Went to the dealer, and he said everything is alright, although my local mechanic says that this sounds similar to several other complaints he has received from his other customers. Their seem to be thousands of affected Hyundai Elantra customers who are complaining of the same issue only to be ignored willingly by the dealers and the manufacturer. My car started developing these noises around 80,000 miles- and Hyundai offers a 100,000 mile drivetrain warranty. Does not seem like Hyundai is honoring its warranties at this point. Hyundai America seems to be testing the strategy where most of the affected customers will run out of warranties or will sell their cars for second hand owners to discover that the original 100,000 mile warranty doesn't apply to them anymore. Hyundai should issue a recall on my model year and affected model year vehicles that are affected by this issue. There is a potential safety concern of engine failure at highway speeds where the occupants of the vehicle may get involved in a fatal incident.

Tl the contact owns a 2013 Hyundai Elantra. While driving at an undisclosed speed, there was an abnormal knocking sound in the engine. The vehicle was taken to wilkins Hyundai (750 n york rd, elmhurst, IL 60126, (630) 279-3000) where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired due to the engines being on backorder. The manufacturer was not notified of the failure. The approximate failure mileage was 64,999. The VIN was not available.

The vehicle was taken to prestige Hyundai (768 e chester st, kingston, NY 12401, (845) 339-3313) where it was diagnosed that the lower bearing in the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 121,000.

At 60k miles, a knocking sound came from the engine after rough idling. The engine oil now has metal shavings. Dealership denied that there have ever been problems. Never missed an oil change. Trying to get dealer to cover under warranty.

My 2013 Elantra's engine recently stalled and now needs to be replaced, and the underlying problem as explained to me by the Hyundai service dept. Sounds extremely similar to the problems that led to the recent sonata recall. Here's what happened: I was sitting at a stoplight when I heard a strange clicking/knocking noise from the engine. The vehicle began to have a very rough idle, shaking noticeably. The engine then stalled. After about 30 seconds of trying, I was able to start the engine again but still experienced a very rough idle and the check engine light had turned on. I took it to the Hyundai dealership. After the service department had looked at my car, they told me the engine needed to be replaced and that they were going to file a warranty claim. I was told that the engine bearings had failed, and that when they don't work properly to reduce friction in the engine, metal shards can get into the engine and cause problems. As I understand it from reading about the recent class-action against Hyundai, this sounds virtually identical to the problems with the sonata engines that ultimately led to the recall. I am still waiting to hear about the warranty (I'm still under the full 5 year/60k miles cpo warranty), but wanted to report this issue since what I've been told is so similar to the issues with the sonata engines. If the warranty claim is denied, I plan to request documentation of the problems with the vehicle and will be happy to provide them to NHTSA.
