2013 HYUNDAI ELANTRA Complaints

Front (engine) subframe rusted out in 2026 after recall work was completed in 2023 for the known issue. Here is the service campaign information: "Service Campaign 984 2011-2016MY ELANTRA (MD/UD) UNDERBODY CORROSION PREVENTATIVE SERVICE"

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.

My mother's vehicle caught fire while in park and it’s listed under a fire-risk recall. Another car got damage with the fire. I want to open a claim.

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

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.

While driving on an interstate on March 12, 2026, the engine stopped working requiring that the car be pulled over to the side of the road. There were no indications of issues as oil had been regularly changed, and the battery and tires were replaced in fall of 2025. The check engine and oil lights all flashed at the time of the incident, not before. Fortunately, we were able to pull over to the side of the highway, and a tow truck brought the car to a service center. The initial diagnosis was that the seal on the crankcase failed. The service center, and now the Hyundai dealer, do not know the cause of this catastrophic damage that may result in the need for a full engine replacement.

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.

A system in the Engine that allows for oil to sit and burn. UNKOWN A Mechanic shop that I go to regularly stated that this has been a known issue that has been going on for the past 12 years. Along side when I bought the car I was told that the engine is usually louder then most cars, this has been the general consensus. Personally with my car no, having done research outside of just my car: UNKNOWN there were no warning lamps, messages, or other symptoms of the problem. I was first told about this issue during the 2nd week of February of 2026, With the oil change paperwork of when I found out about the issue

[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 have had a couple of issues that I have had others tell me or read online that they have had the same issues 1- When I bought the car, which was used at the time. Just a couple of years ago I drove it off of the lot and it had a break issue. I had to take it towed back to the dealership bc something broke underneath and the breaks were failing. So they fixed the problem supposedly. I only had a 30 day warranty and after the 30 days the breaks started grinding every time I stopped. This went on for a long time. I had an other mechanic look at it and did something and I can not recall exactly what he said but after about a week, the noise started back up and at that time I had had the car for about a yr and he said I still had about 25 percent left on my break pads. So probably about 4 months ago I changed my front breaks, including the rotors and the back breaks to, I also had to replace the front left caliber bc while trying to take the pin out of the caliber to clean it, the pin broke. So I replaced it. Took my care in to get inspected And they told me I need to do the back breaks and the back right caliber to pass inspection. So I did the work and got it done. I am not a rich person so I can only take it a mechanic if it something that I can not do myself my I have had good training bc had been a mechanic and had taught at mechanic schools so I know I have help and if I am not sure about something he will help. So now after doing all of that hard work, I am starting to hear the grinding noise again with the breaks and my breaks are good. It always starts our really light and then gets louder within a couple of weeks. 2- the second issue is that my airbag light is on, I am not sure why this is , I have never been in any kind of accident. One day just popped on and never went off 3- I have read online that you have had a recalls on newer models for Hyundai Elantra with the issue but not my year. Well my trunk latch ended up get latched and would not open
