Power train
33 reports1 fire
“WHILE DRIVING THE CAR WHEN COLD THE CAR DOWNSHIFTS HARD INTO FIRST AT ABOUT 20 MPH. ALMOST AT SOMETIMES FEELING LIKE I HAVE BEEN HIT FROM THE BACK. MY NECK HAS STARTED HURTING FROM WHIPLASH. THIS IS A VERY HORRIBLE PROBLEM THAT NEEDS TO BE FIXED. IN STATES WHERE ROADS BECOME WET, ICY, AND COVERED WITH SNOW, THIS CAN CAUSE A LOT OF DAMAGE/ POSSIBLY DEATH.”
Air bags
28 reports4 crashes
“The airbags did not deploy while the car was being driven at 65 mph on Interstate 275 S and crashed into a wall barrier. Since the airbags did not deploy, the driver's head was thrown around because the rest of his body was held firm by the seat belt. The driver was transported by ambulance to the hospital. After several tests, it was determined that the driver suffered a broken neck and spinal damage and must wear as an Aspen neck brace for 6 weeks and then be examined by a Neurosurgeon to determine if there is any further damage or additional medical care is required. The driver is unable to work until released by a Neurosurgeon. The car was declared a total loss.”

“LAST WEEK, ON AUG 29TH 2020, I TRIED TO MAKE A LEFT U-TURN ON A RESIDENTIAL STREET AND THE STEERING WHEEL LOCKED UP.

THE MECHANIC SAID THE BRAKE FLUID WAS LEAKING AND HAD TO FIX THAT. APPROX 2 WEEKS LATER, SEPT 2ND, THE MOTOR BLEW ON MY CAR WHILE DRIVING ON A HWY.
