The car stalled was not possible to stear and brakes didn't work... I had to coast luckily I was only in second to right line and easily got to emergency lane!!

NHTSA complaint #10979986, filed 2017-04, 50,500 miles“While driving my car started alarming saying check charging system...it immediately went to 15 miles and hour while I was on i95 where speed limit is 65 MPH. By the time I got home and turned the car off it would not turn back on. Ive had this car for a year and a half. I bought it new.”
NHTSA complaint #10969997, filed 2017-04, 60 miles“When pressing the accelerate pedal there seems to be a delay in response. The delay can be as short as a few milliseconds to almost 3 entire seconds. This problem happens randomly, and makes my wife and I very nervous when trying to maneuver or proceed into traffic after being stopped.”
NHTSA complaint #10808593, filed 2015-12, 5,000 miles“I was driving in the rain on 1/16/19 with my son, all of a sudden my car starts beeping and my dash board says stop driving now and check your charger system and after one hour it completely died, had to get towed home, now the dealer says the problem was the high voltage relay and connector that goes to the high voltage battery on the car that caused the battery to fail and charger system. Now I'm told I need to buy a new battery and I feel this should be covered b the warranty since this issued caused my battery to drain.”
