Instrument Panel problems of the 2001 Mercedes Benz M Class

Since the car was purchased it continues to hesitate and stall out giving a "start error" on the instrument panel. Had confirmed by the service manager, gerry griffith (car purchased in indianapolis, recent move to alabama), that the model m-class has problems with this issue. Just had to spend $1000+ on a "fix" and the problem has been ongoing since the beginning of purchasing the car. Detailed service records are not given to the customer only a brief synopsis and all work is not included in that report, I. E. , the actual testing codes, etc.
