The tachometer registered zero rpm's, even when accellearting. Attempting to accelerate up any incline and the car can not provide enough power. Sometimes the car will crank up, other times it will require time to restart. The car has stalled and low power idling multiple times, but it did happen in the middle of a 4 way intersection twice, and when the issue is present. Although we've been fortunate, no accidents have occurred, it is very unsafe for the owner and other drivers. This occurance has happended several times over the past year. Two times it was immediatley brought into the dealer service, the second time it did stall with the service member there. Both times they were unable to diagnose the problem and stated no error codes were reported. You have already issued a recall for this same issue with a different model. Oct. 13, 2017 – Hyundai motor America has recalled more than 400 vehicles potentially equipped with defective crankshaft assemblies, according to documentation submitted to the national transportation safety administration. There are so many others that have reported this same issue and have been corrected with the replacement of the crankshaft position sensor. . Read more...

My vehicle is a 2019 Hyundai Elantra. It has the Hyundai nu 2. 0l engine, which has been the subject of recalls for engine failure, stalling, and sudden loss of power. The check engine light came on but not before the majority of the dangerous driving conditions surfaced, meaning I had almost no warning before the issue put my life in danger. My vehicle was not included in the recall even though other models with the same engine had been. I experienced unpredictable stalling, hesitation, and engine failure while driving. On several occasions, the car stalled unexpectedly in traffic, creating a serious safety risk; I nearly was rear-ended multiple times. The vehicle became increasingly unreliable, prompting me to take it to the dealership. The dealership confirmed that the engine failure was consistent with the known nu 2. 0l engine defect. There was metal debris in the oil even though I have kept up with maintaince and oil changes at the regular intervals suggested by Hyundai guidelines. Hyundai covered approximately 90% of the engine replacement under a “good faith” adjustment. Documentation of engine inspection and repair available upon request.

The engine of my 2018 Hyundai Elantra has a rod bearing defect covered under a safety recall. The vehicle has not been repaired yet, and the issue prevents the car from being safely operated. I have incurred towing expenses due to the inability to use the vehicle, and I am concerned about potential engine failure or safety hazards if the defect is not addressed promptly.

The contact owns a 2020 Hyundai Elantra. The contact stated that while attempting to turn at approximately 5 mph, the traction control warning light illuminated. The contact pulled over to the shoulder of the road and restarted the vehicle; however, the vehicle failed to accelerate as intended while the accelerator pedal was depressed. The check engine warning light was illuminated. The vehicle was towed to a local independent mechanic, where it was diagnosed with excessive oil consumption, catalytic converter failure, and related the failure to NHTSA campaign number: 21v301000 (engine). The local dealer was contacted however, the VIN was not included in NHTSA campaign number: 21v301000 (engine). The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 89,709.

I started to see the oil light on the dashboard and I heard a hard sound from the engine so that I changed the oil then after a couple days I saw the light again on with a little bit high temperature, so stooped by a gas station and I added some more oil after I shut the car off and waited to cool the engine down and I started the car, the oil light was gone and the engine sound was smoother then I started to get the same issue every couple days and I used to fix it the same way and I've had the same experience with my previous car which was the same brand but different year band model which I found a recall on the engine after it blown and the agency or the manufacturer changed the engine for free for that car and the current car has the same issues and it's included in the year range for that recall which from 2012 to 2019, that scares me because I drive everyday for rideshare and that can be dangerous for me and my clients who ride with me, also some of them stopped calling me for rides once they knew about that issue. And today I noticed the car beep which I used to hear when I lock the car with the remote has stopped too.

I started my vehicle and it was running sluggish and low idle. I had an engine light and when I tried to drive there was a clanking sound. When I had the engine light tested I received the following codes: p0017 - crankshaft position correlation bank 1 sensor b, p0303 - cylinder 3 misfire detected, p0302 - cylinder 2 misfire detected, p0301, p0014 - exhaust camshaft position timing - over advanced (bank 1), p0030 h02s heater control circuit (bank 1, sensor 1) I had it towed to my nearest Hyundai dealer in tacoma, wa. After they did a diagnostic they said that they would have to replace the engine due to a shearing of a pin, leading to the belt jumping and causing issues. I am the only owner of the vehicle, I have had all my oil changes on time and my vehicle is 137,000 miles. This should not be happening in a vehicle with such low mileage. In reading online, this is an issue that Hyundai is aware of but not concerned with. There was no warning beforehand. This could have led to my engine stalling on the the freeway at freeway speeds and thus could have caused a great accident and bodily harm to myself and others. Hyundai has denied responsibility but knows this is an ongoing issue with it's poorly manufactured engines. I was not informed of all the problems of Hyundai vehicles before I purchased mine. I have yet to receive help from Hyundai customer service or the Hyundai dealer.

Car had check engine come on with no significant symptom. Mechanic said this code leads them to either timing chain, phasers, or piston valve all located in the engine. The car does not have much time at this point. It’s very costly after just having changed all the oil gaskets from a leaky engine. Mechanic said it will suddenly get bad if left unpaired and could be dangerous for me while driving.

I purchased a 2018 Hyundai Elantra on April 3, 2024, from carmax. At the time of purchase, I was not told about any recalls. Later, I discovered that my vehicle is covered by Hyundai service campaign 993 (anti-theft software upgrade), issued February 13, 2023, which addressed the lack of an immobilizer in 2011–2022 Hyundai vehicles. On may 29, 2025, my vehicle was stolen due to this defect. When it was recovered, it had a blown engine and was completely inoperable. Hyundai acknowledges that my VIN is included in the recall, but they have only offered to install the software update now. That does not remedy the damages caused by the theft and resulting engine failure. Carmax has denied responsibility, claiming they were not aware of the recall. I am now left with a financed vehicle that is not drivable and has lost significant value due to Hyundai’s defective design.

Engine timing chains are failing in a direct result from recall campaign id 21v301000 piston ring noise sensing system which contaminated my oil accelerating wear on my engine chain and sprockets. A failed or ineffective piston ring noise sensing system can let piston/ring damage go unchecked, leading to oil contamination, which in turn wears out or destroys the timing chain system.

The contact owns a 2019 Hyundai Elantra. The contact received notification of NHTSA campaign number: 21v301000 (engine); however, the part to do the recall repair was not yet available. The contact was stationed in guam when the vehicle was purchased. The vehicle was manufactured in south korea. The contact then moved to the USA, and the vehicle was taken to colorado however, the vehicle was registered in florida. The dealer was contacted and refused to repair the vehicle, because the vehicle was considered a foreign vehicle. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Large amount of oil consumption. Told by dealership that engine replacement is needed.

The issue involves the hybrid electric powertrain or electrical control system in my 2023 Hyundai Elantra limited hybrid. The vehicle has shut off multiple times while driving, with complete loss of power and propulsion. This poses a serious safety risk, as it happens without warning in the middle of the road. Restarting the car requires shifting into park and trying multiple times to turn it off, but the vacuole turns back on the first try. I have experienced this issue several times, including twice during a 300-mile highway trip. After each shutdown, the dashboard displays multiple warning lights, including the check engine light, battery light, oil pressure light, and hybrid system warning (orange car icon). I took a photo immediately after the most recent failure to document these warnings. The vehicle has been inspected three times by two different Hyundai dealerships. Both confirmed the vehicle is under warranty but have not repaired or diagnosed the issue, citing that they cannot replicate it. They have driven it ~200 miles without success. However, they have not pulled ecu data or freeze-frame codes, even though warning lights were active at the time of failure. There are no symptoms or warning messages before the failure — the vehicle shuts off suddenly. The car is available for inspection, and I am in the process of opening a formal case with Hyundai. This is a significant and recurring safety hazard that must be addressed. This issue has an occurred a various speeds including during acceleration and braking. The picture attached is the dashboard after the I indent has occurred and have shifted to park after stopping to try and restart the car to get out of the middle of the road.

The contact owns a 2017 Hyundai Elantra. The contact stated that after starting the vehicle, the vehicle lost automotive power and then lost power after driving a short distance. No warning light was illuminated. In addition, there was an abnormal sound coming from the engine. The vehicle was taken to a local independent mechanic; however, the failure was not replicated. The contact stated that the vehicle was previously taken to the same independent mechanic, and the spark plugs were replaced. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 150,000.

The knock sensor detection system (ksds) software malfunctioned by failing to detect abnormal vibrations or knocking sounds. As a result, there was significant internal engine damage that caused the vehicle to seize unexpectedly in the middle of traffic on 4/10/25. The car started and abnormal noises were noted from the engine though not significant. Week later, car stalled several times on interstate. Prior to the failure, the vehicle exhibited a progressive knocking noise in the engine. After seizing, the vehicle would struggle to start, idle briefly, then stall. It also randomly shut off while driving, creating a serious safety risk. The vehicle was taken to precision tune auto care, where technicians confirmed problems with the crankshaft, excessive oil consumption/leakage, and metal shavings in the oil, which they attributed to rod bearing and crankshaft wear consistent with Hyundai campaign 203 (improperly heat-treated piston rings). Despite the ksds being installed during the initial recall remedy, the system did not activate prior to engine failure. Additionally, no engine or oil warning lamps were illuminated. An oil change was performed at the time, but the vehicle had already burned through excessive amounts of oil since the prior change. Precision tune auto care advised me to take the vehicle to allen turner Hyundai. At the dealership, staff confirmed issues with the engine but refused to acknowledge recall campaign 203, even when presented with documentation. They also failed to address the malfunctioning ksds system or the lack of functioning engine/oil warning lamps. They were asked to perform inspection relating to piston ring and rod bearing, though refused. This situation raises major safety concerns, as my engine seized in the middle of traffic without warning. Other owners with a malfunctioning ksds system could face the same risks, leading to sudden engine failure, potential engine fires, or serious traffic accidents.

Abs and traction control lights on as well as e brake light this is all after I had recall work that was supposed to fix this problem but only made it worse I am dealing with Hyundai but I don’t see a solution for this problem my car is inoperable and very unsafe it is my main source of transportation to and from my place of work and without this vehicle I am at a great loss I have lost brakes completely at times and am mentally and physically unable to drive this car it’s that bad financially strapped from sinking money into this problem only to find there’s a recall but the recall work didn’t fix the problem and Hyundai knows it won’t fix the problem.

Driving on interstate at 70mph. Multiple, five or six, warnings pop up in rapid succession mostly dealing with the safety features such as distance to car in front, adaptive speed control, lane keeping. The last one was hybrid system - safely stop. The car then immediately lost all acceleration power leaving us coasting. This all happened within a few seconds. Terrifying. Luckily we had space to get over quickly. 30 miles sooner we would have been in downtown jacksonville with no place to maneuver. Extremely dangerous. A few seconds warning then nothing. Turned the vehicle off as soon as we stopped and car was completely dead, no electrical power to anything, including flashers. Not sure how you can’t have flashers on a hybrid. Basically no warning to no power at highway speeds and then no flashers. Something is seriously wrong with this.

A significant class action settlement, known as the Hyundai engine ii class action settlement, was established to address allegations of engine defects in various Hyundai models. This settlement includes vehicles equipped with the nu 2. 0-liter gdi engine, such as the 2014–2020 Elantra gt. The lawsuit claimed that these engines could suffer from issues like engine seizure, stalling, and potential engine fires. My vehicles engine is the engine listed above and has been experiencing those exact problems. My engine has been stalling and making a knocking noise. A professional mechanic evaluated my vehicle and diagnosed it with first stage engine failure. Engine failure of any kind while driving is extremely dangerous and could lead to sudden stopping on a highway, collision, and result in the loss of life of both the driver and other drivers sharing the road. In addition to the engine ii settlement, there was a separate class action settlement related to the theta ii engines, which are also found in some Hyundai vehicles. This settlement addressed allegations of engine defects that could lead to engine failure. Hyundai motors is refusing to honor their warranty coverage for my vehicle. They claim their refusal is due to my vehicle having a rebuilt title, however, nowhere on their website or per any other guidelines do they explicitly deny coverage for rebuilt title vehicles. They clearly state that only salvage titles and 'total loss' vehicles will not receive any warranty assistance, which my vehicle was never considered a total loss. Additionally, when speaking to a bob howard Hyundai representative, they informed me that they have previously honored warranties for people in my exact situation. The engine in my 2014 Hyundai Elantra gt is the original engine with a matching VIN number and the engine failure is strictly due to the malfunction of said part produced by Hyundai motors. I have maintained and preformed regular maintenance on this vehicle with receipts.

While driving in a parking lot. The car wouldn't accelerate. Kept pressing on the gas pedal but the car wouldn't move. After about 5 seconds the car shut down. I had to place the car on p then press the start button, pressed the brake pedal and then the start button again and the car turned back on.

See attached document for complaint.

Burning oil internally. Adding 1 quart about every 1000 miles.
