2015 HYUNDAI SONATA Complaints

Engine burns 2 quarts of oil a week. Took it in for oil consumption tests and Hyundai figures out ways to not replace these faulty GDI Engines. Also car has a strong gas smell inside car. Maybe gas leaking. Airbag warning light has been on for years. Took it to the dealer in the past they said it's ok(Hub Hyundai Katy TX) but I don't feel confident.

Engine had a leak and shaves of the engine were inside the oil line. Had to get engine replaced.

The contact's husband owns a 2015 Hyundai Sonata. The contact stated that while her husband was driving at an undisclosed speed, the vehicle lost motive power. The vehicle was towed to the residence, where it was diagnosed by an independent mechanic with engine failure. The mechanic informed the contact that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

Multiple times, when the car start up and is put in to reverse, there is no throttle response. Simultaneously, it can not be put into the manual gear select mode and the car lurches into second gear.

Driving at 55 and the engine blew. No warning, no check engine light, no sign of anything wrong. Power steering loss, limo mode activation. Almost rear ended during catastrophic failure. 111,000 miles

The top of the low pressure fuel pump in the fuel tank was cracked. A strong fuel smell was present near the rear of the vehicle. When the vehicle was placed on jack stands, leaking fuel was visible on the sides of the fuel tank. The rear seat was removed, fuel pump access cover was removed, ignition was turned on and fuel was observed leaking from cracks on the top of the low pressure fuel pump. This is a huge safety concern due to fuel leaking from the fuel tank. I know for a fact this is not an isolated incident, you can watch YouTube videos of others with the exact same problem. The dealers want $1K+ to repair. I was an ASE Certified mechanic for 20+ years experience, I purchased an OEM fuel pump through an online retailer for ~$600 and replaced it myself. Problem solved, but for how long? There were no warning lamps or messages, the only sign was the strong smell of fuel.

The vehicle is slow to accelerate and as its accelerating it often will jerk or hesitate roughly. There have also been times when accelerating, such as getting on a highway, that the whole (what I assume to be) throttle system will almost stop and it feels like the car is just going to stop right there on the highway. It's very dangerous as cars behind me are also accelerating and not expecting my vehicle to just stop. The vehicle is available for inspection. There are no warning lights, messages, or symptoms prior to the issue. It has not been inspected by anyone yet.

Vehicle suddenly lost power while in operation. Vehicle was in motion approaching an intersection. When left turn indicator was activated, all lights on the instrument panel illuminated, the engine shut off, and power steering was lost all while the Vehicle was in motion approaching a intersection with stop sign. Vehicle was able to stop before entering the intersection, but would not start again and we were stranded in the middle of the road. Electrical systems appeared to be working. Battery and alternator are functioning normally. After Vehicle sat for 20min, it then was able to start and moved out of the road to a safe location. Vehicle was towed to mechanic that confirmed Battery health and alternator functioning. Vehicle was then taken to dealership for recall 210 safety repair. Dealership service unable to determine cause for loss of power while Vehicle in operation. No explanation, offer of additional service, or remedy has been offered despite requests. I do not feel it is safe to operate this vehicle in the absence of information related to the sudden loss of power during normal operation. Had this occurred in another setting with more traffic or less room for safely coasting to a stop, serious injury or worse could have resulted. The vehicle is still eligible for the 10yr 100k mile powertrain warranty and I am the original owner. We do not feel we can safely operate this vehicle and need guidance on how to proceed with pursuing a remedy to the situation from the vehicle manufacturer.

My ABS lights came on and then minutes later my check engine light kept blinking while my car kept stalling or not let me accelerate in the middle of traffic. It’s like the engine dies but the car is on. It only stalls for a second then accelerates then stalls again and accelerates. Almost caused an accident. Seems that this is a problem for a lot of these models. It’s just crazy how it all happened back to back. My car has been running fine otherwise till that happened.
