Car engine stopping while running and a no start. Service engine light warnings over a long time. One repair by mazda on the gas cap repair, but I have also uncovered a recall on leaking seals at the tank on 2003 models, 03v‑531. Service light again came on from 10/18/10 -10/30/10. While out of town the car sat airport parking on my return it stopped without warning at a light 11/22/10, but all lights and radio stations were active, so no battery problem. After adjusting the filler gas cap several times I found it wasn't closing and could be pulled right off. We have made sure the cap is on tightly each time and since cancelled the dealer appointment for a $100 inspection, no light since. 2/9/11 after driving 35 miles the car would not restart, aaa came out and no battery trouble, but a 30 mile towing was required to my home. The vehicle sits in a garage avg temp of 35-45f. The next morning after several attempts and using both keys it restarted and we took it into a dealer. @2 days later they find a "service bulletin" 901-009/07) from 2007. Possible @ -30c (zerof) the no start or crank due to moisture within the main relay and/or fuel pump relay. That night 25-30f in nov no way close. On 02/12/11 while driving on is77 the car quite running again, 911 called as I made it to the side of the road under heavy fast moving traffic. This week on 2/22 while in the garage hesitant to turn over again but did start on the 3rd try, vehicle temp reading was 47f. So now for 2 new parts for 2003-2005 models and $450+ repairs can be made. The parts are in and per the bulletin looks more like a by-pass option than replacing a defective oem part. Cutting out while driving is very serious, as much so as acceleration on a toyota. Since my company is tied to the tire/wheel & auto mfg and we conduct 1/2 dot tire test for the USA, I'm pretty sure I know what I'm talking about on defects.

2003 mazda 6 recall 1403l, campaign # 03v531000, on my vehicle supposedly was repaired in baton rouge at diamond mazda in 2004, but car is leaking in the same area that was a problem to begin with now. So the workmanship where they repair the seal is not very good. Four years later I buy the car and it is poor gas on the top of my gas tank out of the seal around the fuel pump which just happens to be right under where my child sits. So I've been in a time bomb just waiting to go off. No one can give me proof or paper work of where this recall has been taken care of. Now suppose that it did blow up and kill or injure myself and my 3 year old daughter. Wouldn't mazda be at fault for not properly repairing the vehicle?
