The car also has hard start problems and spongy brakes.The stalling problem occurs most at high speed when decelerating.The car runs fine otherwise.It does not leak oil or any other fluids.

Car Review: 1992 Mercedes-Benz 300SL
November 06, 2016, 07:48 PM
I bought my 1992 300SL 5 months ago,May of 2016.and from the start while driving the car from CA to WA it had rough start problems.The brakes were spongy and even after having the master cylinder replaced and the entire brake system checked twice the brakes are still spongy.The factory radio failed long ago and I replaced it with an aftermarket unit.But the most chronic problem of all is high speed stalling.On the freeway,uphill,downhill,all of a sudden the motor stalls and is not easy to restart.It happened again just today,Nov 06-2016,in a most dangerous situation.We were driving down a steep grade and suddenly the car stalled when I let up on the gas pedal.The car would not start and we were now going down a very steep grade without power brakes or power at all.We were lucky I found a turn-out to stop and even then it was very nearly impossible because the brakes are very difficult to use without the motor on.This condition is now scaring me and my lady friend now refuses to ride in the car.Can anybody help me with this serious problem?The car has 174K miles and is still a very clean car.Could this be an ignition problem?Thank you for reading my review.
