ENGINE
I am writing to formally file a safety complaint regarding my 2020 Hyundai Elantra. I recently learned that Hyundai issued a recall related to a defect that poses a risk of engine fires in certain vehicles. However, my vehicle, which has exhibited the same dangerous symptoms, was not included in this recall campaign. Specifically, my vehicle has experienced a critical error relating to a defect included in NHTSA Recall #21V-301, which I understand is directly related to the safety defect identified in Hyundai’s recall. Despite this, I have not received a recall notice, and Hyundai has declined to provide repair coverage under the recall. This raises serious concerns for my safety, the safety of my passengers, and the public. A defect that can cause an engine fire should not be limited to specific VIN ranges if the underlying issue is present in additional vehicles like mine. I respectfully request that NHTSA investigate this matter and ensure Hyundai expands the recall to include affected vehicles such as mine. If Hyundai continues to exclude vehicles with the same defect, I believe this could warrant further legal and consumer protection actions, including potential class action litigation. Please find my vehicle information below: 2020 Hyundai Elantra VIN: [XXX] Mileage: 51,000 Thank you for your time and attention to this urgent safety concern. I look forward to your response and am willing to provide additional documentation, repair invoices, or photographs as needed.

ENGINE, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I have taken my car in twice due to my car braking when there is not a vehicle and or object in front of me but there are vehicles right behind me that have to brake but Crain denies that there are any issues. My engine light came on a couple of weeks ago and I took it to Auto Zone to have a diagnostic test done. The report states that it has something wrong with the transmission/transmission line and or fluid. When I looked it up online it stated that there are recalls on engine pistons that could cause the diagnostic test to read that it's the transmission. My car is a 2020 Hyundai Elantra value edition but according to your website, there are no recalls!?

ENGINE
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.

ELECTRICAL SYSTEM
Vehicle had several non-starts. I took it to the dealer a couple of times and they could not duplicate the problem. This problem continued for a couple years before I took it to an independent mechanic. Said mechanic put it on a lift and found a loose power cable barely connected to the starter. Luckily this never caused a short, spark, or fire. From my searching online it appears this is a non-infrequent issue with Hyundai's.
