Rotten egg smell from exaust. Dealer showed me mazda's service bulliten which states it comes from higher sulfer gas, and will dissipate by 10,000 miles. Now have almost 8,000 miles with no lessening of smell regardless of gas used. (slight improvement with amoco) someone inky had newer catlysts installed by mazda with good results. This should be done across the board for anyone with this problem.

While driving vehicle stalled without warning.
Sulfur (rotten egg) smell in vehicle cabin. Dealer said no fix from mazda related to exhaust issue, several complaints, issue lasts up to 8k miles. Car has less than 800 miles.
The engine light and transmission light indicated a problem to me, as well as the car jerking upon acceleration. After taking the car to the dealer for service it was determined that knock sensor had malfunctioned. Since the first visit to the dealership for service regarding this problem, it has happened 5 times. I have contacted my dealer and the manufacturer and am still dealing with this issue. My dealer has made no attempt to rectify the situation other than replacing the engine sensor over and over. The car was out of commision for over a week each time. I have gone to the dealer asking for their help in contacting mazda about a new engine and or car and they are completly uncooperative.
While driving, the vehicle stalled. The dealer was aware of the problem. *ph since the vehicle was turned around leading to downhill, the vehicle restarted. Two dealers didn't know what was wrong. The vehicle did not run at 8500 elevation. The consumer was left sideways in the road when there was hesitation. *scc
There is an odor coming from the exhaust. I have taken the car to the dealer two times for this, and they told me it was the gas I was buying. So I started buying gas out of town for a while, the odor continues. I have 12,000 miles on the car, and the odor keeps getting progressively worse. But the dealer keeps telling me it is the gas, and offers no help.
