1999 Mercedes-Benz SL500 Problems

Harsh Ride From Rear Due to Failed Dampening Actuator

Vehicles with automatic level control that ride harshly in the rear (no give in the suspension) may have one or both dampening actuators which have failed. It is commonly recommended the actuators be replaced in pairs.

Erratic Engine Operation and Poor Fuel Economy Due to Faulty Mass Air Flow Sensor

A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.

Hard/Soft Tops May Develop Problems Due to Age

As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.

Bought this 1 1/2 yrs ago @ 83,000 mi. Now has 89,000 and is 15 yrs. old. Can't believe how in love I am with it. Everything works, nothing has gone wrong. A true head turner. Hope I didn't just jinx myself with all the accolades.
I love everything about this car. It is a sports car but with a little more room. The ride could be a little smoother, but I think if you have the right tires the ride becomes better. I really like the turning radius and for being a convertible it is pretty quiet with the top up. The Bose stereo is great, I just wish it had an ipod adapter. I have had only minor problems with this car and h...
