“I was driving northbound on I-295 in washington, dc when my check engine light illuminated and the car began to slow down in extremely heavy traffic and I lost the ability to accelerate. I attempted to accelerate in order to get my vehicle off the busy highway and to a safer location, but I was not able to go more than a few meters. It was fortunate that I was not seriously hurt or killed. …”

“This is an ongoing safety issue that I've tried to get the dealership to address. From a stop or slow idle, the engine exhibits acceleration hesitation. This hesitation lasts up to 2 seconds and when trying to merge into traffic has nearly resulted in accidents numerous times. I believe a Hyundai whistle-blower came forward recently to expose this ongoing issue but Hyundai has yet to address it.”
