The cars breaks are difficult to stop, it does not slow down. The steering wheel is very stiff to turn. And my car was stolen due to Hyundai not equiping it with an immobilizer. It was recovered smashed in the front, no airbags were deploited. I have photos for proof.
The brake system continually fails intermintently and is placing the driver and all passengers at risk of injury and or even death. The brake pedal stiffens not allowing pressure to be applied to use brakes. The pedal has to be pressed in aggressivly 5-10 times before finally allowing brake assist to help brake the vehicle. Once pedal begins to activate again it is followed with heavy grinding then finally almost resumes as normal with normal braking. The brake assist system has failed on almost 10 occasions on myself and has been taken in for repairs 4 times and fails to be repaired and appears to not ever be located. The recall regarding the brake booster was fixed, but yet brakes continued to fail after repair. The dealership has since taken it back in for repair and said they located leaking rear back brake pistons and repaired that. …
The vehicle has experienced ongoing powertrain and electrical malfunctions over several months. The most common symptoms include being stuck in 4th gear (limp mode), complete loss of RPM and speedometer readings, and illumination of the check engine and ESC lights. Most recently, while traveling at approximately 10 mph, the vehicle experienced a sudden loss of both acceleration and braking. The brake pedal became stiff and unresponsive, and the car had to coast to a stop without driver control. This posed a serious safety risk to myself and nearby traffic. These issues have persisted across multiple service visits to Ricart Hyundai in Groveport, Ohio. That dealership has replaced the crankshaft position sensor three times, the powertrain control module (PCM), and the battery, but the underlying problems remain unresolved. …
Have had the vehicle throw a code for a misfire 4 times in the 30,000 miles I have driven it. The times I have taken it to Hyundai dealerships in Northglenn and Boulder, Colorado they tried an update and just swap ignition coils to different cylinders. Example misfire is cylinder 3. They swap number 3 and 4 ignition coils to see if they can recreate the problem I the new cylinder. There is already a TCS 20-FL-001h. I recommend a full recall of these defective ignition coils be put out as the problems are still occurring. The problem is reoccurring and the time it takes to get into the shop is 3 weeks out at this time. By the time I get it in the code usually resolves and I have to wait until I get violent shakes and poor acceleration to indicate it is back. Had an accident in January if 2023 and it seemed the brakes were t working as they should. …
When my car was stolen and crashed the whole front end was smashed in but the air bags did deploy. I saw there's several recalls on these cars, one was the airbags. I never got any recall for it and it shows there are no recalls. The brakes have problems, being that it takes forever to slow down. I have to leave about 3 car lengths ahead of me because I can't stop, it takes a while to slow it down. And the steering wheel feels stuck. I had a friend drive it and he said the same thing. It's difficult to handle and not lose control. I'm to the place I'm scared to get on the highway anymore because not being able to stop quickly and swerving all over cause it's hard to control the vehicle. I have had zero recalls tho even with me experiencing this. And the paint is coming off, but at least that won't kill me.
Had bought the vehicle at 72k miles, and drove fine for a few months before the engine started to sound like it was roaring (like the exhaust had came undone), shortly after vehicle started stalling and dieting turning left (have video evidence of this in parking lot) did not take vehicle in to be serviced as it seemed a lot of the time to be a one off issue but now the vehicle has lost a lot of low speed acceleration, and had begun knocking at 80k miles where it was looked at by an independent mechanic which stated that the engine was severely low on oil. Have been driving since as it is the only way for me to get back and forth to work and the problems have been getting worse to the point the vehicle will refuse to start, or just act like it's lost a gear and is stuck in neutral
Without any warning lamps coming on, the vehicle car stalled while driving on the highway. It randomly stalls constantly when turning corners, especially on left turns (odd?). The scariest thing that happened was it got stuck on the speed limit of 55-60 miles per hour and I couldn't brake or accelerate. This put my kids, other drivers, and my life at risk. On Father's Day, while my husband was out with the kids the vehicle tried to accelerate on its own when he was at a stop. It happened multiple times as he tried to make it home. Then when he was in stop and go traffic, it got difficult for him to brake. The brakes started failing. What more can I say?
2017 Hyundai Elantra GT suffered leakage from the hydraulic brake lines located under the driver's seat which can cause sudden and total braking failure. The leakage was caused by severe rust and corrosion trapped by the underbody panels. The fuel line was also severely corroded, with imminent failure. While Transport Canada issued an official safety recall for this exact engineering defect on the same generation of Elantra GT under Transport Canada (Campaign 2023125), Hyundai Motor America has failed to extend this protection to U.S. consumers, leaving vehicles on U.S. roads with active, life-threatening brake and fuel line failures.
