Driving from palm springs to los angeles on highway 10, a very loud clunk heard beneath the drivers seat and vehicle lost power but continued to rev. Slowly recovered. About 10 minutes later, at speed of 65 in traffic on highway, another loud grinding clunk heard somewhere beneath driver's seat. Vehicle again lost power but continued to rev. Best way to describe is that it felt like the car was suddenly dropping from 5th gear to 1st gear. But the gear shift was not touched. This happened in traffic on a major highway. I see there are dozens of similar complaints registered on this site. Please take action before someone is hurt.
