2012 HYUNDAI ELANTRA Complaints

My engine has failed- I started with the piston slap one day when it started up engine light came on drove it right to dealership and almost didn’t even make it this is very scary and to know I only have a little over 114000 miles and not being covered being a second owner

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?

My car was parked in front of my house on street. I found rear hatch glass shattered from the inside. There was glass several feet away from car on road. There are no rocks etc. inside or outside of car. This is the second time this has happened. The first time was June 2021 at an event I was attending. Same thing, glass exploded everywhere. We assumed it was due to the heat (it was in the high 80's that day). The flying glass could have hurt someone nearby. The technician who looked at the car could not explain how it happened.

Airbag light on on. DTC code B1346 , Driver airbag resistance too high ( 1st stage)

Initially it stalled while idling in my driveway on 2 different occasions. Several days later on a short errand 8/2/21, it stalled at a red light, the engine puttered, and it failed to shift gears at 20-25 mph and 40-50 mph unless I alternated between letting off and then reapplying the accelerator. Just continuing to press the accelerator made it slow down. No warning lights came on, but I took it to a local repair shop. They couldn't replicate the problem on several attempts, so I picked it up and drove it home slowly. I was afraid to use it - trying to accelerate on an entrance ramp and having it slow down would be dangerous. After it sat 2 months, my husband went to drive it a little. It stalled at a stop sign and had trouble shifting gears again. When I went to drive it to the repair shop, the Check Engine light came on immediately. I drove it carefully, and it was OK. The shop called the next day. They replaced the crankshaft position sensor because of a code, and it was ready. On the way home, it shook violently and flashed the Check Engine light the 2 times it tried to go to second gear. I had it towed to the repair shop. They couldn't replicate the problem, so they replaced the crankshaft position sensor again. As soon as I started home, it acted up again. I went back and had a mechanic ride with me. It acted up. He said he hadn't pressed the accelerator as hard as I did, he'd never seen anything like it, and to take it to a Hyundai dealer. I had it towed to a Hyundai dealer. They replaced a switch inhibitor, valve solenoid, harness, and gasket valve body cover - all in the transmission. As soon as I started home, it acted up again. I turned around and took it back. That was 11/18/21. I called on 11/23/21 and told my service writer about the NHTSA investigation opened 11/12/21 for speed control problems and said I thought my car might be having this throttle problem. He said he hadn't heard about it, and he's going to call me back tomorrow.

The contact owns a 2012 Hyundai Elantra. He stated that while his wife was driving at various speeds, the vehicle would independently brake with the ESC warning light illuminated. The contact's wife drove at a slower speed once the failure occurred. The contact had taken the vehicle to a dealer where they were unable to diagnose the vehicle failure. Upon investigation, the contact discovered NHTSA Campaign Number: 15V871000 (Electronic Stability Control) which he linked to the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 81,000.

Going down a hill breaks completely failed and had to go off road to avoid increased speed. Resulted in Hitting tree. By failed I mean no pressure on break pedal and with pedal pushed to floor it did nothing to slow or stop vehicle. Now breaks seem to be working again but worried this will reoccur while at faster speeds.

All of these issues occur in any weather or if the car is warmed up or not. They don’t occur all the time but about half the time. -From a standing stop (like when entering an intersection or turning on to a road) lightly pressing on gas pedal will get car moving then in 2-3 seconds it will stall out for 2 or 3 seconds, almost to the point of the engine stopping. At that point, moderately pressing on the gas again will cause the car to accelerate suddenly & forcefully. It is terrifying when a car is coming at you & you don’t know if it’s going to start accelerating or just die. -Driving and maneuvering in a parking lot is quite a risky adventure. At these slow speeds the car will randomly stall, lurch, hesitate & accelerate suddenly & forcefully with just a light touch on the gas pedal. Not the best performance when trying to park or maneuver around closely packed cars. -I have taken the car to the dealership at least 5 times to remedy this problem & they either said this behavior was not detectable or it was operating as designed. I have documentation consisting of service invoices. They obviously weren’t being truthful, considering the Recall & Class Action Lawsuit that has subsequently been issued dealing with this issue, revealing that HYUNDAI knew about this problem. Can I finally get my car to operate properly & SAFELY?

I honestly believe I was ripped off for this vehicle I’ve been having to replace one thing after another since I’d gotten it. The brake system on the front passenger side seems to keep grabbing when I’m not even touching the brake. every time I change the brakes only the front passenger side gets worn down way more then the others. I was thinking it was brake drag, but I litteraly greased my brakes and guide pens then it started making the squeeking noise again when I wasn’t touching the brake. It also compromises my engines functions. my engine lags out and I have a feeling it’s putting more torque into the engine and transmission than it was supposed to, and now is causing problems in them. It causes safety issues because the brakes are one of the most important systems on a vehicle it can cause me a bad accident if the caliper becomes to worn from heat damage, because it excessively is putting pressure on it. I haven’t taken it to the dealership to recreate the issue yet, but I did mention it in the very beginning because I had suspicions of my vehicle having problems, but they said they couldn’t find anything when they ran the vin. They didn’t actually test my vehicle which was what I needed. My check engine light has been on.
