Warning Light On Problems of Mercedes Benz ML320

This is a complaint concerning a 2000 Mercedes Benz ml 320. The srs warning light comes indicating that the air bag system is not functioning. First time was April 2006, vehicle was taken to napervill Mercedes Benz. Advised that there would be a $300 diagnostic charge. Problem was "baby Smart" sensor in right front seat. I was told that I could either eat the $300 charge or have it fixed. Final bill was $1,063. 86 problem re-appeared February 2008. Called same dealer and was advised that same procedure would be required to fix. I have declined to go through this again. Checked on internet by googling "ml 320 srs failure" and found numerous cases of same problem. Checked for recalls and did not find anything.

Safety system failure, including braking assist, seat belts, air bags and tel-aide due to computer chip failure. Caused two accidents after which customer paid to have vehicle reviewed bumper to bumper and the failing chip was replaced. During this time, the dash warning lights did not illuminate to warn of the failure which the vehicle computer documented 15 times in a six-month period (between the two accidents). Approximately eight months later, the warning light on the dash illuminated again. Do not know how many times system had failed since it was 'fixed. ' traded in vehicle for safety purposes.

If the vehicle was driven for 25/30 minutes and turned off and then restarted, the air bag off warning lights came on. The dealership was unable to duplicate the problem.

After driving the car for 30 or so minutes, stopping and restarting the car, the "air bag off" and "srs" warning lights come on and stay on. Per vehicle manual, when these two lights are on it means that the air bag system may not be functioning properly. The air bags may go off when they are not supposed to or they may not trigger when they are supposed to. The manual says the car should not be driven and should be taken to the dealer for repair immediately. I have taken the car to the dealer several times, they told me they could not find anything wrong, but when I asked them if they could assure me the air bags would work properly or not, they said they could not say that either. This has been an ongoing problem for at least the last 10 to 12 months.
