The vehicle itself shakes when accelerating and will start to fail once 60mph is hit. It will also cut out when left turns are made...I have met 4 people with the exact same issues who received recalls but I am not sure why my car is not included. I was almost rear ended on the highway by a semi with my pregnant wife and 4 year old son in the car because of the engine failure.

Minutes after continuing driving on the interstate around 50 to 60 mph, every light on the dash came on the vehicle stopped accelerating, and the warning light check HEV system shut engine off started flashing. The vehicle would no longer start again after this. the dealership said that the fuse was being oversupplied, which is what caused the system to fail. This exact situation is listed in a recall for 2013 to 2015 Hyundai Sonata hybrids. After reading the recall notice., my vehicle had this failure due to the exact reasons listed in the recall notice. due to the damage that was caused by this fuse that could not hold enough electricity my wiring harness also has to be replaced. This could be a three to $4000 out-of-pocket expense for me that should be covered under this recall, due to its exact nature of similarities. please assist me. I do not have the complete invoice due to the fact that the dealership is withholding that information until the repair is complete However, hyundai motor is also aware of this issue, and I am filing this complaint for this investigation to be moved with urgency

2017 Hyundai Hybrid Sonata lost power while in the middle lane of [XXX]. Following notice appeared: Check Hybrid system. Turn off engine !HEV. We were able to coast over to side of road (car was going 70mph at time of breakdown). Car towed to McDonough Hyundai dealership. Talked to Service Dept. We explained our situation to him (out of town, spending money on a hotel). They performed an engine electric Diag. which stated: Vehicle had multiple codes for low battery voltage. Test battery and got an instant failure. Cleared codes and test drove after new battery replacement. No codes came back. Approximately 1 hr. later in Jackson, GA we were on [XXX], middle lane & engine stalled (70mph & coasted over to side of highway). Received same code: Check Hybrid Battery System, !HEV, turn off engine. Had car towed to Kennesaw, GA. Rented car to drive home & had car towed to Alexandria, KY our home town. After 2 wks. car was put on diagnostic machine. Said they test drove car multiple times. They said could not duplicate the issue. It was suggested the next time we get code on our dashboard to take a picture of it or video. Took car to Kerry Hyundai, Florence. Test driven car 40 miles & have gotten nothing. No codes. Told them it was imperative that your mechanics find the issue. I will not drive the car as it is now. It is unsafe as it stands now. Breaking down 2x in GA. The first time after driving it 6.5 hrs. and the 2nd time after putting brand new battery in & breaking down exactly 1 hr. after driving. We have been without our car since [XXX]. Hyundai advertises a great warranty on their cars, one reason we purchased it. We wanted a SAFE, RELIABLE car since we are both retired and going to travel. We are out of $1,827.08 & afraid to drive car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving the 2017 Hyundai Sonata Plug-In Hybrid, the car will begin to stall, a rapid number of audible beeps will start, the "Check Hybrid System" notification will pop up on the dashboard, and the "Check Engine Light" appears.. The car therefore cannot be driven anymore, and I am forced to pull over to the side. In order to fix the issue temporarily, I need to turn the car off and turn it back on again. Once this is completed, both the "Check Hybrid System" and the "Check Engine Light" disappears and the car can be driven again. An OBD Scanner is unable to find exactly what is going on as the "Check Hybrid System" and the "Check Engine Light" no longer appear. This has happened 4 times now within the span of 3 months. The people at risk are me (the driver), my passengers, and potentially everyone else on the road in my nearby vicinity as the problem occurs. This problem has been confirmed by the dealer in their Hybrid vehicles. This vehicle has not been inspected yet but that is an ongoing process.

- Brentwood, CA, USA

Problem 1: I made a right turn at a red light. As I turned my power steering light turned on and my steering wheel locked up and I lost control of the vehicle. After stopping and turning off the vehicle, I restarted it. At this point I was able to regain control of the car. A few days later the same thing happened again as I made a right turn from a parking lot into the flow of traffic. One again I stopped the engine and restarted the car, then I regained control of the car. Problem 2 (May be related): My passenger side headlight was replaced a year ago. Recently the light went out again. I took the car in to a mechanic to repair it. It was repaired so I thought. Two days later the light went out again. The mechanic believes their may be an electrical issue. Problem 3 (May be related): My driver side brake light was replaced about a year ago as well. It has now gone out again. I have had my vehicle serviced twice by a Hyundai dealership at least twice since the first incident.

In May, the engine completely failed as I was driving on the freeway, without cause. It had to be towed to the dealership where luckily the engine was replaced under warranty. Less than 6 months later, the HEV and CEL warning lights came on as I was commuting to work via highway. The car was very low powered, hard to accelerate, and immediately decelerated whenever I started to let off the gas pedal. It struggled to go at or above 60-65 mph. The freeway speed was 70 mph and it was a safety risk for the car to power down. Dublin Hyundai could not replicate the problem, simply recharged the battery and said I was good to go. Less than 1 week later, the exact same thing happened as I started on a road trip. I had to return the car home and get it towed to Stockton Hyundai for diagnosis. This is car is only 6 years old, has been routinely maintained, and just hit 100k miles, for which Hyundai is denying any repair assistance even though there is a lifetime hybrid battery warranty.

Engine Shut Off Without Warning problem of the 2017 Hyundai Sonata Hybrid While driving the car on the freeway, it will jerk forward and then shortly after lose power.

I have looked into this warning over a year and no one seems to know the problem. This should be a recall and all Hyundai dealers should be made aware of what this warning is. We as Hyundai owners need answers and help.

The hybrid system failure. Chrck engine light is flashing. Abs system failure. Battery failure. Car can't go over 45mph, lost a job because of the issues. I'm afraid the car is going to blow up or catch fire. I'm afraid to drive it. The acceleration is barely there. It's like the car doesn't even wanna go. It sucks through gas like no other.
