2013 Hyundai Elantra: engine knocking or ticking

Filed Apr 11, 2026 · Transmission · PA · crash

2013 Hyundai Sonata has a loud knocking noise from engine. Purchases 8/5/25 at 43K miles, currently at 44K miles. There is a Technical Service Bulletin, # 22-EM-009H dated June 2022 about an extended warranty but its time limit is questionable. Unknown and undocumented when purchased. Not listed as an official recall so not covered under warranty repair and the only course of action I have been given is install a new motor quoted at $15K from local Hyundai dealer. Further research shows that driving should be limited to avoid further engine issues/fires. Occurrence since January 2026. Progressively worsening. Cause for concern. Is there an official recall on for the piston flap pending? Unsure if accident noted below is due to the issue.

A significant engine failure occurred while driving, presenting as loud knocking from the engine. The issue developed without prior warning lights or messages. The vehicle was inspected by a dealership and the problem was confirmed as internal engine failure (piston slap/engine knock). The dealership recommended full engine replacement. The engine is available for inspection upon request. There was no evidence of sludge or lack of maintenance noted during inspection. The most recent oil change had been performed less than 1,000 miles prior to the failure, indicating the issue was not caused by lack of maintenance. This condition creates a safety concern due to the potential for sudden engine failure, loss of power, or engine seizure while driving, which could increase the risk of an accident, especially at highway speeds. The issue has been confirmed by a dealership and has not been repaired due to cost.

My vehicle has a piston slap ticking issue and Hyundai will not help me fix this because it’s a common issue by Hyundai.

The vehicle has developed a pronounced knocking noise that was diagnosed by your authorized dealership as “piston slap.” I was informed by dealership staff that this is a known issue with this vehicle. However, because the vehicle is outside of warranty by time and mileage, I was told no repair assistance would be provided. My primary concern is safety. While there are currently no warning lamps illuminated, the engine is producing a consistent knocking noise. If this condition progresses to piston or engine failure while the vehicle is in operation, it could cause sudden loss of power or engine seizure. Such a failure at highway speeds or in traffic could create a serious accident risk to myself and others. Additionally, I was charged one hour of diagnostic labor, despite the dealership immediately recognizing the noise as piston slap without needing further testing. This raises concern that: The issue is well-known, The condition was identifiable without extensive diagnosis, Yet I was still billed for a full diagnostic hour. Given that this is acknowledged as a known issue, I am requesting: A formal review of this case by your product safety and quality department. Clarification on whether this condition has been the subject of technical service bulletins, extended coverage programs, or internal advisories. Consideration of goodwill repair assistance due to the potential safety implications. Reimbursement of the diagnostic charge, as no true diagnostic procedure appears to have been required. Written confirmation that continued operation of the vehicle in its current condition does not present a safety risk. I am prepared to provide service records, invoices, and any additional documentation needed. Given the potential safety implications, I respectfully request a response within 48 hours. I am hopeful the manufacturer will stand behind the safety and reliability of its product and address this matter promptly.

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 the federal safety agency investigate this known defect in the 1.8L Nu engine, as it poses a safety risk to myself and others.

My engine is ticking. The auto shop told me that my motor is shot and the same thing happened to my sons car. We both have the same car same year. There has been a law suit for this issue.

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 federal safety agency 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.

Car has a ticking sound, car has died on me multiple times. The vehicle has stopped moving regardless of pressing on accelerator and died leaving me stranded, feeling unsafe. I have been driving at 40 mph and then seem to lose power, making it to where can only go 10 to 20 mph or totally dying. I was also having issues with key fobs not working. Door would open, unlock and then not, car stalling. No lights illuminating on dash. Battery in fob replaced after car being towed to shop after stalling, dying issue and I was basically told they didn't know what was up with the stalling, maybe fobs. I had an oil change done and full diagnostic, sent on way without answers. Happened again, electrical issues, fob not working, stalling, start hesitation and dying, no power. I had it towed to different shop and was told had couple of codes showing up even though no check engine light on, they stated a caliper was leaking along with other oil leak and crankshaft sensor needed replaced, which got fixed. The car has 98000 miles on it (around there) and I see safety recall posted. I finance this car and have literally only had it not even 5 months. I do not feel safe driving it. I've been stranded, at times key fobs and locks act up on it still, the ticking is definitely a concern, RPMS off and revs up at times while also lacking pick up and go. I contacted my local Hyundai and they stated no resolution on safety recall yet, can schedule an appointment and pay for diagnostic, which would make my 3rd diagnostic over the last month or so. I need something remedied. I transport myself and at times my children and I do not feel safe in this vehicle which again purchased just about 5 months ago from Car Max. Help please!

The engine in my 2013 Elantra started making noises and the car stopped while my son was driving. He was able to get it to a nearby parking lot. We ended up driving it 1 mile to the mechanic who said “it might be time to get rid of this car”. It needs a new engine. Mechanic talked to the local Hyundai dealership, gave them the VIN and dealer said I would likely be eligible for an engine replacement under a recall or a factory warranty. I towed it to the dealer to do their own “diagnosis” before they could give me the official word that my engine would be replaced. Dealer kept my car for five weeks. They ultimately provided an estimate of $3K worth of repairs that have little to do with the engine failing. I'm not sure they even looked at the engine. They told me the car has too many miles and would no longer be eligible for an engine replacement. I ultimately had the car towed back to my mechanic. The mechanic is estimating about $8K-$10K worth of parts and labor to replace the engine. The mechanic does not suggest using a used engine. My car is displaying the same issues as the other engine recalls, but my particular model is not covered (yet). The 2014 Elantra is part of the engine recall. My 2013 Elantra is not covered but is still displaying the same symptoms, and the engine knocking noise and engine failure are the same. The "Check Engine" light is on. I have this car parked in a parking garage, unable to be driven, while I pay off the remaining balance to Carmax. My mechanic says it could "blow up" if I drive it, and at a minimum, the engine can fail while driving causing a safety risk to the driver and passengers and any surrounding vehicles or pedestrians. I can provide mechanic's contact information if needed.
