My vehicle "check charging system" warning came upon the start up of the hybrid in the morning 12/31/2018, going to work. This was an issue on a heavy precipitous day in past. However there was not heavy rain, I turned the vehicle back off. It turned on without the warning which 1st appeared in front area and is audible. It started as I approached a stop sign. I live about 6 minutes away from work. The battery life is visible and it was not changed from mid point which has always been same. The tank had gas, no issue, and I drove it to work. I assumed with the car turned off for the 6hour shift I had, that it would possibly be relieved. I started the car to now drive to the store for quick grocery essentials. Within a 15 min time frame from work, store quick shopping there, and home again. The warning came back on. As I braked, or came to a stop for lights the warning would stop. As I pushed on gas pedal it would start. As I was approaching an intersection with traffic lights, I prepared to stop but as I got closer the car would not stop anymore than it had (which was significant) but not stopping, as I noticed the distance, my foot on the brake all the way I heard the vehicle (closing song) which is supposed to be heard when you turn the vehicle off. I looked at the dash in front of me which went blank all across the board and I braced for impact. My vehicle came to a stop because the collision occurred with this malfunction and my car hit the car in front of me. Physically we are ok. I am still paying for this vehicle and it is powerless by the curb at my residence until I can afford to have a tow truck pick it up. The dealership said no warranty, no assistance by them. I have a claim with Hyundai which is slow. You tube has so many vehicles from 2011 and recent models that are reporting same warning issues. I have a recording of it from that day.

While car is in motion, on highway or anywhere at anytime, the check brake warning light comes on display screen, with an beeping alarm, then the brakes drop to floor barely stopping the vehicle with a grudging noise. I went to the dealer, they gave me the option to replace the ABS system but was not sure of the exact problem and tried to sell me a newer car. This company already has lots of recalls and has put many people's lives in danger. This issue is happening to many other vehicles the same as mine and they are not safe for anyone.

I was driving on the freeway at approx. 60 mph and the parking brake suddenly engaged. The dash alarm went off and the car starting making terrible grinding noises and swerving lane to lane. I was able to fight it and make it to the right shoulder. After turning the car off and on again it disengaged and I was able to drive it for a short distance before it happened again. I had it towed to my house and will take it to the dealer on Monday.

Charging system malfunctioned, sensors melted in valve trane, radiator elbow and fill neck blew off, complete engine failure and battery failure. I have had a problem with the "check brake" light and an alarm going off. However, when I stopped driving and had it towed to the dealership they could find nothing. Prior to this incident, I took a photo of my dash, I had 76,499 miles and the coolant meter did not read hot. I had had the coolant system flushed at 65,000 miles, and I had all oil and fluids checked again after this incident. The breakdown: Three hours into a roadtrip, the A/C began blowing warm, simultaneously - the "the check brake" light and alarm came on, and the "check charging system" light came on. I lost power to accelerate (or brake well) and immediately pulled over and took a photo of my dash warnings (76919 miles). The heat sensor was in the "cool" half, the battery gage showed no power. Battery so low key would not start car. I had the car towed. "tech found that elbow and radiator have holes in them vehicle overheated causing engine to blow." Tiffany richardson said "tech believe vehicle was driven with low coolant level causing vehicle to run hot melting sensors in the valve train and the pipes to fail." The tech is wrong, the coolant system was inspected and flushed at 65,000 miles, and was not due for another inspection. I had had coolant levels checked less than 1000 miles ago, and the heating sensor on dash did not read hot, at the point of breakdown or after a road trip 500 miles ago. Others had the problem at 3000 miles! it's the hpcu. The power for both electric motors is routed through hpcu. The inverters allow the A/C motors to be driven by D/C batteries. This caused the "check charging system" error. This is $15,000 and I owe $4000 on the car - 100,000 warranty has denied it & I am original owner.

While coming to a stop at a traffic light, my brakes malfunctioned. The brake warning light came on and the peddle became slack. The peddle fell to the floor. I was able to stop the car before entering the intersection. After a moment the brake warning stopped and the brakes worked again. This happened again as I was parking my car in the driveway. I have video of both incidents. Dealer has been notified, but is not able to schedule a repair for 5 days. It will have to remain parked as I am concerned about safety.

As I was gently applying my brakes in heavy freeway traffic, going about 50mph, the brake pedal became soft and dropped to the floor. The brake failure warning light also started to flash and chime. I swerved off to the side of the road to avoid hitting the car in front of me and plowed through some plants on the shoulder prior to coming to a stop with my parking brake.
