“While traveling north on us 221 from bent mountain, va to roanoke va my hydralic steering totally failed. As I travelled a short distance my brake light warning lights, ABS light, other brake system light, battery light and air bag warning light came on. I looked at the engine temperature guage and the temp was normal. I pulled into a parking lot, raised the hood, checked the fluids in the engine compartment and reentered the car. While sitting in the drivers seat I heard a loud explosion, looked forward and noted thick steam coming from the engine compartment. …”
NHTSA complaint #10865773, filed 2016-05, 102,000 miles“While driving on the freeway, on a slight incline is when I noticed the RPM was high and the speed reducing. (along with some crackling, rough noises from the front end of the car) I let off the gas pedal (lowered the rpms), tried to accelerate but the car wouldn't regain speed the car eventually reduced driving speed to 30mph with RPM at 5. I moved over to the shoulder of the freeway and waited for help. With a child in car. Transmissions should not fail on a vehicle at 50,000miles. Very scary situation. I hope this issue with this make/model/year vehicle is addressed. …”
