Please find below a description of the malfunction in my Hyundai Elantra, as this is the reason I'm requesting inclusion in a recall. Since the week of Thanksgiving 2022, I've had several instances of my vehicle stalling without warning before engaging the transmission; for example, my car once stopped moving completely on the freeway while entering the onramp at 55 mph. Since then, the problem has only gotten worse, stalling up to seven or nine times per week. Because of the severity of this issue, I've had it inspected multiple times and would gladly submit it to another one if requested. Obviously, a defect of this magnitude with no obvious cause not only puts me at risk as the driver, as I can't prepare for a sudden stop, but all road travelers around me are also subject to this issue. As you know, a sudden halt could lead to collusion involving numerous people. …
Since day 1. Brakes have failed. First recall took years. They "updated my software " brakes still failed. They failed to believe me "Couldn't find a problem " there's no warning lights no nothing. Out of nowhere. The Brake goes to the floor. Makes a grinding sound and your either going towards on coming traffic or a ditch. Brakes failed at numerous intersections. How I'm alive is beyond me. The best part, either the seat belt is too baggy or strangles you there's no in between. My entire steering system is junk. wasted money on tires alignments brake pads brake censors. Dealership has another recall on these brakes with no remedy. I've sadly driven this car over 10 years with failing brakes. I drive with my right hand on the e brake ready to yank it at any given times. I'm honestly traumatized by this car. Engine and transmission are junk. Nightmare
Car has been properly maintained for years. No accidents or known major issues. Suddenly the car would not start one workday morning. The tow truck driver was unable to start the car; towed car to repair location. Nationally known major service station said the car was low on oil, they filled with 2 quarts. No prior oil problems, no oil or engine idiot light on dashboard was lit, no oil puddles/stains. Car returned to owner, on short drive home, the engine trouble idiot light turned on. Used code reader to find P0014 - cam shaft positioning error code. Brought to local service station, was told car needs a new engine. No outstanding recalls. Recent newspaper article stated there have been problems with 2012 Hyundai Elantra engines. Maybe locked engine is related to other known issues?
