   The vehicle experienced severe, sudden loss of power while driving, leaving the car unable to exceed approximately 40 MPH on public roads and highways. This restriction creates an immediate rear-end collision hazard and severely degrades acceleration under traffic conditions. Diagnostic & Technical History: The vehicle previously triggered Diagnostic Trouble Code (DTC) P1326 (Knock Sensor / Engine Limp Mode). Diagnostic testing at Holler Hyundai under Techline Case…

   I purchased the vehicle from a private party on 8/18/21 with 38,310 miles. Almost immediately after owning the vehicle I noticed the engine oil level was low.. The owner had said she had just got an oil change so I thought maybe the shop just left it low. Then I noticed it low again a month later, and that was the start of my nearly 5 year journey of having the carrying quarts of oil in the trunk of my car because the engine was burning the oil so quickly. Finally on 5/08/26…

   My 2015 Hyundai Elantra fits the 'window' of Elantras where the engine transmission slips gears without notice. Hyundai dealers have been replacing transmissions at no cost, if the car is still under 100,000 miles, as part of a class action settlement. As the second owner, I have no warranty rights to get Hyundai to fix my car at no cost. This is despite the Hyundai dealer just today (Aug 20, 2025) here in Las Vegas was ready to replace my transmission at no cost until they…

    Check engine light came on, the code says misfire on random cylinders, drives very rough. Took to mechanic and said timing chain is loose, which causes the “skipping” or misfire, and could snap at any moment (which is unsafe and could cause a wreck). Mechanic has 3 other Hyundai Elantra's with same problem. Around 2 grand fix.
