Experienced a completely unexpected (and potentially dangerous) stalling while driving (I.e., not while stopped). This sudden stall was displayed to the sonata's driver panel as hybrid system failure, and the alarm was triggered to beep continuously. This may be related to the 12V lead-acid deteriorating, with capacity degraded to 110cca from specified 600cca. Even though the battery was degrading, the car should not stall just because the battery capacity is low.
Car has 65K miles. Warning "chime" came on, total loss of power, pulled of road safely. Warning light on dash came on... hybrid system warning...safely stop... do not drive...then....check brake....then back to hybrid system warning...do not drive....then back to check brake. And on and on. I shut off the car after a minute and restarted car drove another several miles and then same situation. I have seen a video post on youtube and have seen other posts as well and one with a vehicle having only 3500 miles. I'm trying to see that this should be a major safety concern as shutting down completely is not acceptable and totally unsafe.
Please contact me immediately my business number is [xxx]. I am not here to bash Hyundai because I been a loyal customer for 10 years. The 2013 hybrids have a big problem when accelerating. I am not sure what exactly but I will try my best to type it accurately. When you are driving and U come to a red light or a stop sign or even jus braking do to traffic the engine stall and does not accelerate. I almost died 3 times in this car because of this issue. I was at a stop sign and a truck was down the street to my left there was no in coming traffic to my right I proceeded to hit the gas but the vehicle rolled slowly and I still had my foot flat on the pedal, it took almost 17 seconds for my engine to actually move my car which was almost flipped by the incoming truck driver who thought I was going to turn and keep going left in the opposite lane so he didn't hit brakes from early and my engine kicked in and acted like I was doing a burn out meaning for example at a dead stop and I floor the pedal causin the car to take off faster than normal safe operator practices.but I almost died today and the check light comes on and off I have a bunch of videos of this problem. Please help information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
As I was driving home from work at aprox 9pm my car started to make this loud abnoxious sound that states for me to slowly stop and do not drive. As I was attempting to maneuver from the fast lane to the side, my car completely shut off. I was so afraid because there were other cars and trucks right behind me and I feared for my life.I am told that this issue is not under warranty but it has been reported by man. I just purchased the car a year ago and should not be having these issues. This is unsafe me life threatening and needs to be resolved asap. I have also read reviews online and have discovered that there are many others in my same situation and that they too have been in la life threatening scenario in regards to this defect with the same exact car.
The contact owns a 2013 Hyundai Sonata hybrid. While driving 50 mph, a warning indicator illuminated directing the contact to place the vehicle in park. Also, the battery charge was low. After waiting an hour for charging, the vehicle jerked and bucked. The warning indicator illuminated again, stating that the battery voltage was extremely low. The vehicle was towed to an independent mechanic, but the cause of the failure was undetermined. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was approximately 97,000.
