1998, Mercedes ML320, 70,000 miles, both catalytic converters need to be replaced. There is a major campaign for recall on this part for Mercedes to replace at no cost to the owner, however, the year of the car is in question. This incident happened 4 months after the 8 year warranty ran out.

While driving in traffic, the vehicle seems to be leaking exhaust directly into the passenger compartment causing me to have severe headaches and feel very tired. It helps somewhat with the odor when the HVAC is switched to recirculate, but I feel that co is still seeping in the vehicle.

Catalytic converter needs replacing. Engine is sounding very loud. The check engine light is on. Part was ordered in September 2005. As of today, 12/30/05, the part is still not available. The Mercedes account manager said over 1200 catalytic converters are on back order for the us and there are 2 people who have been waiting longer than us in austin for the part. He said it may become a recall. Why are so many of these parts all failing at the same time that supply cannot keep up with demand? I feel my vehicle may be unsafe to drive and have no access to a part to correct the defect.

Our 1998 Mercedes M320 has been subject to unexpected stalling for some time. More recently this has increased in frequency and we have periods of loss (reduction) of power while driving. The dealer advises that we have deterioration of the catalytic converters and that there has been a recall for this problem on newer models of the M class - but not our year. We have the car at the dealer waiting for replacement parts. We are told it will be a number of weeks since the parts are in great demand. Repairs will cost over $2,000 - but the car is clearly unsafe. Most frequent stalls are starting at a light or stop sign. One concern is knowing this problem with model years just newer than ours are subject to recall while our year isn't. the other issue is how difficult it was for the dealer to identify the problem until it became very severe (or they learned of the solution due to the recall of other years.

The right side catalytic converter split at the neck. While the local Mercedes Benz dealer freely admits that this is a common problem on this class of car and that there is a recall on this very problem, they tell me that my VIN number is not covered and if I want to avoid the problems associated with a leaking exhaust system, I must replace it myself. This is obviously a much wider problem than Mercedes Benz is willing to admit to.
