[XXX] is subject to Safety Recall 20V-755 Hyundai Recall 251 for a defective ABS module that may leak brake fluid, cause an electrical short, and increase the risk of an engine compartment fire. The recall remains open and has not been performed. On Feb 2, I brought the vehicle to McGovern Hyundai of Arlington and disclosed an active brake fluid leak consistent with Recall 251. I also stated that brakes were recently replaced 4 weeks ago. The service advisor incorrectly said the recall was just for a fuse and unrelated to brake fluid. The dealership drove the car for a state inspection despite knowing about the leak and open recall. They stated the brakes are bad and requested payment for a diagnostic, which I declined. No diagnostic testing was performed. The dealership informed me the required ABS module part was unavailable and instructed me to return Friday, waiting 3 5 business days. The recall repair was not completed, and no towing or alternate transportation was offered. The dealership invoice documents the incomplete repair. I live in East Boston, MA, a densely populated urban area with street parking. If the defect causes a fire, it could endanger nearby vehicles, residences, and public safety. I am filing this complaint to document the unprepared safety defect, dealership misinformation, and ongoing community fire risk.

I was driving and my car just shut down. Thank goodness I was only in a drive thru because my car was still in gear. I got it restarted and it was making a terrible noise. I took it to hyandai where they told me that I had a piston slap. Hyandai corporate knows that this is a problem. I am lucky to have not been on the highway it could have caused serious injury or death to me or anyone around me. Hyandai corporate should replace the engine that they know is bad or if someone has had it replaced they should be reimbursing. Them. It's dangerous the 1.8l 4-cylinder nu engine.

On August 9, 2025, my 2013 Hyundai Elantra suffered catastrophic engine failure while driving. The engine seized, creating immediate danger on the road. This vehicle is under NHTSA Recall 23V651000 (Hyundai Recall 251), which warns of fire/engine compartment risks both while parked and driving. Hyundai denied my claim, citing a vendor report that found -??no thermal damage-?? to the ABS wiring. However, the dealer-??s inspection confirmed internal engine failure with thermal damage, and I directly witnessed flames. The recall does not require ABS wiring itself to burn, it covers the broader safety hazard of fire and failure, which is exactly what occurred. In addition, Hyundai tried to shift blame onto owner maintenance. Their own recall language acknowledges failures occur due to the defect, not neglect. Furthermore, the handling by Hyundai-??s case managers was unacceptable: my case was transferred without notice, calls were ignored, and I was left without clear instructions or remedy while my vehicle was disabled. I have attached the denial letter, the dealer report, the recall notice, and proof of maintenance. I request NHTSA review Hyundai-??s mishandling of this recall obligation and require them to provide remedy and compensation

My 2013 Hyundai Elantra with the 1.8L Nu engine suffered catastrophic engine failure. A mechanic found metal shavings in the oil and diagnosed a failed connecting rod bearing. The Hyundai dealership quoted $10,000 for a new engine and refused warranty coverage because I am over 120,000 miles, even though this is a well-documented defect. Hyundai issued TSB 22-EM-007H covering rod bearing wear in this engine, and there have been class actions and warranty extensions for similar failures. This failure creates a safety hazard, as the engine can seize or stall suddenly while driving, increasing risk of an accident. I request NHTSA investigate this known defect in the 1.8L Nu engine, as it poses a safety risk to myself and others.

After the recall at Hyundai, my car wouldn't run and there were many lights on the dashboard. It was later checked and the instability light problem persisted. They fixed on the same time, and say something problem with the update. They later informed me that I have a problem with the brake switch, and the brake lights don't work because of it. I replaced and doesn-??t work, I went back to the store and they want me to pay a fee to have it analyzed again. Even though before the recall, the lights and the car were working perfectly.

This seems to be a very common and serious issue with Hyundai vehicles. 2013 Hyundai Elanta, believed to be a frequent crankshaft position sensor issue. When driving the car, they vehicle will feel that it is losing power. When coming to a stop the engine will idle so low that it feels like it will stall or it does stall. 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 occurrence has happened several times over the past year. Two times it was immediately 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.

The engine of my 2013 Hyundai Elantra GT failed due to a known piston-slap issue, and it is available for inspection for a limited time before being sold to a junkyard. This failure occurred suddenly while I was on the highway, putting my safety and the safety of others at risk as I had to maneuver the car to the side of the road amidst heavy traffic. The problem has been confirmed by both the Hyundai dealership and an independent service center, who diagnosed the piston-slap issue and found the engine filled with sludge, a known issue with these engines. Despite having 28 documented service records and regular oil changes, Hyundai denied the warranty claim, citing engine neglect. Hyundai representatives have inspected the vehicle and provided a technical bulletin documenting this defect. Prior to the failure, there were no warning lamps, messages, or other symptoms indicating a problem with the engine.

I took my car into Hyundai due to the recall sent out to car owners. I had my ABS and Brake light that went on randomly around September. I scheduled an appointment and took it in to get it checked. Hyundai sent me away stating there were no parts to fix the issue and told me to pay for a diagnostic if I needed it looked at and to wait until the recall is remedied. Two months later my car exploded and caught fire while parked on my property putting my life and home at risk. As well as my neighbors lives who came in to help me Put out the fire.

Engine has "piston" slap or knocking, a precursor to catastrophic engine seizure, diagnosed at Joe Machen's Hyundai at 132k miles on [XXX]. Engine could seize causing rapid deceleration at any moment, while pulling out into traffic or travelling at high speeds on the highway. First noticed a clicking or ticking noise the engine made when it was cold around 130k mi, which goes away as engine warms up. Sound has gotten louder and more persistent and has turned into a knocking. Dealer told me that the entire engine needs replaced, which is prohibitively expensive. So I'm driving it now until I can get a new car or engine replacement. I've submitted a claim to the dealer and Hyundai corporate, but was denied. I don't believe that Hyundai is taking responsibility for the safe operation and reliability of their cars. I have also not found the dealer to be a support and advocate. There was a limited class action lawsuit where Hyundai settled for some faulty engines where there were metal burrs leftover in the oil passageways during manufacturing that causes engines to fail even when oil changes were done regularly [XXX] ). However, I don't think anything close to the number of engines with actual problems have been addressed. Mine wasn't in the recall but has the piston slap. I got regular oil changes with average 4,405 mi interval through today, while 7,500 mi interval is recommended in manual. I have another friend with a 2017 Elantra that failed at 95k miles, and another with a Kia that failed. Since Hyundai/Kia are very common cars, and owners often don't have the ability to replace the entire engine, and sometimes get no warning, the engine manufacturing defect needs to be looked into further by the NHTSA and Hyundai/Kia as a grave safety concern. Hyundai/Kia need to act promptly to prevent death and injury to their customers due to catastrophic engine failure. We don't feel safe.
