Headed to my work ,outside temp 26 deg F, when on hiway entrance ramp, vehicle lost all acceleration. Vehicle is a hybrid, condition no warning lights on dash, vehicle was stuck in EV mode, which the ICE engine would not start to help as normally would do. Hybrid battery began draining very quickly. There was a semi truck right behind me accelerating hard to get on highway .This time I managed to pull over on the debris filled shoulder before the system fully shut down as it has done before with the warning š ï¸ HYBRID SYSTEM FAILURE, PULL OVER NOW ! and loud alarm going off. This is a serious loss of total motive power, which I’ve reported to Hyundai Corporate, and dealerships for repair before, to which they say ‘ we can’t duplicate, all systems are fine’, and blame me for the problem. Hyundai has washed their hands of this dangerous situation and won’t help me. This is the 5th occasion of this problem, I now know from my experience and reading Hyundai forums this issue is wide spread among Hyundai Tucson and Santa Fe hybrids, with some places replacing parts, that dsn’t fix the issue. I know how to react by pulling over immediately, shut off the vehicle completely, wait… Then restart the vehicle, and so far ,it will drive normal with no codes or warnings after that, until the next random occasion it happens. This is extremely dangerous in cold weather and around other traffic posing a major collision hazard and stranding someone who knows less about this condition. Hundreds have reported this as per the forums, yet no recall or TSB or real fix has been issued by Hyundai.
