I am writing to formally report a safety concern regarding my 2018 Hyundai Elantra. The vehicle has experienced a failure of the heater hose/pipe, which appears to be made of plastic and connected to a metal component. This failure has resulted in a coolant leak, creating a serious risk of engine overheating. This issue is not only inconvenient but also dangerous. A sudden loss of coolant while driving can cause the engine to overheat without warning, potentially leading to engine failure, loss of vehicle control, or leaving the driver stranded in unsafe conditions. This is especially concerning while driving on busy roads or highways. Based on my experience and discussions with repair professionals, this appears to be a known issue with this model, as the part is not widely available outside of Hyundai/Kia and may indicate a design flaw. A critical cooling system component should not fail prematurely under normal driving conditions. Given the safety risks associated with this defect, I believe this issue warrants further investigation and consideration for a recall or extended warranty coverage. Consumers should not be responsible for costly repairs caused by a potentially defective design. I respectfully request that Hyundai review this issue and provide assistance with the repair, as well as take appropriate action to ensure the safety and reliability of affected vehicles. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing a formal complaint regarding my 2017 Hyundai Elantra SE (VIN: [XXX] ). The vehicle is currently experiencing severe safety issues, including unexpected engine stalling and loud mechanical rattling, alongside a P0014 diagnostic code. These symptoms align directly with the defects described in Recall 203 (NHTSA 21V301000) involving improper piston ring heat treatment and Service Campaign 966regarding engine bearing wear. As a consumer, I am extremely concerned about the risk of a crash due to sudden loss of power. I am really concerned for my son and I as I drive my vehicle. I am requesting: 1. An immediate inspection and confirmation of eligibility for an engine replacement at no cost to me. 2. Verification of the lifetime long-block warranty extension associated with the KSDS (Campaign 966) update. 3. Provision of a loaner vehicle or rental reimbursement while my primary vehicle is unsafe to operate. Please assign a case manager to this matter and provide a timeline for resolution.

The back camera has yet to work since shows black screen, and then the lane Assistant shuts off in the middle of the road and there’s nothing blocking it. lights went out and kept going out no matter how many times I replaced the bulb when I was on the highway. I took it into Firestone and they stated that the company fucked up the wiring system.

My vehicle has been in the shop here at McGrath Hyundai in Chicago, IL 30+ times since I bought it 5/21. Electrical, (rear), 6 horns, 6 blower motors, multiple warranty and recalls and now my front driver seat belt. They’re refusing to fix it even though I have reported it before. They’re saying over 60,000 miles makes it no longer under warranty. I reported it before and they said that it was okay. It was not okay and still isn’t okay and they think I’m going to pay $1500 to get it fixed now as well as re wiring the back of the vehicle for $600, which I have been reporting issues with for years.

[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.

IN SOME VEHICLES, THE MANUFACTURER'S PROTECTIVE INTERNAL COATING OF THE ELECTRONIC CRANK ANGLE SENSOR DOES NOT MEET SPECIFICATIONS, WHICH CAN CAUSE AN OPEN CIRCUIT AT HIGH OPERATING TEMPERATURES. THIS CAN CAUSE THE VEHICLE TO STALL.

Consequence & remedy

Consequence: ENGINE STALLING HAS THE POTENTIAL TO RESULT IN A VEHICLE CRASH IF IT OCCURS WHILE THE VEHICLE IS MOVING.

Remedy: DEALERS WILL INSPECT THE CRANK ANGLE SENSOR TO DETERMINE WHETHER THE SENSOR IS INVOLVED IN THE RECALL, AND REPLACE ANY SENSOR FOUND WITH THE DEFECTIVE INTERNAL COATING.
