The consumer received a recall nhtsa#94-v-094-000 on may 1997 on the radiator cap pressure relief valve. The release pressure was set too high which could cause the coolant to reach temperatures that exceed thermal design limits of some components of the coolant system. Should this occur the engine coolant could leak directly on top of the engine. The consumer stated this recall failed. *Nlm the recall was partially completed. Both required replacement of the cooling system including the water pump which was not done because the vehicle lost the water pump on the road. *Scc *jb
Oil line to turbo's collapsed causing the inner coolers to be flooded with oil. This was caused by the apex seal coming off in the rotary tube which caused the compression levels to drop. This damage costs me in excess $10000 and happened at 30000 miles. An investigation is currently under way. *Jb

On 11/16/99 I was driving about 40 mph and my engine cut out. I drove the car to classic motor cars. They contacted me to let me know that my car had lost compression and that the engine would have to be replaced. I contacted mazda customer relations to determine what recalls had been applied to my car. They confirmed that mazda recall #60504 and #65609 had been applied. I asked about mazda recall #54407 and [[redacted]] stated that I was not notified of that recall because according to the computer, my car...

did not need the recall. Upon further investigation he identified the vin #jm1fd33**p0200001 through jm1fd33**r0302076 should have been notified of that recall. Since my vin #[[redacted]] falls within that range, I asked why my car shouldn't be considered to have the recall. He said he didn't know. It seems that there is a computer problem. I should have been notified and had the recall work done. In specific, I understand that this recall work prevents the engine compartment from catching fire. Since my vehicle was not included in this recall, in error, I would suspect there are many others that should have been recalled, that were not. This negligence is a potential threat to me, my family and my property. Also, I believe that since my car wasn't identified to have the recall work done, that this contributed to the deterioration of the apex seals in my engine. Any engine should last longer than 49,800 miles. Upon contacting mazda, the dm has agreed to offer $1,000 towards the replacement of the engine, but they do not feel that this is a defect. I feel that since we are not identified in their computer as recall candidates, and since we were not notified to have the recall work done, and since we did not have the recall work done, the apex seals have deteriorated as a result of the heat generated inside the engine that causes fires in the engine compartment without warning. I would like for your agency to assist me by confirming this. Information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(B)(6). *Tr

Recall site shows 3 recalls for 93 mazda rx7. Engine cooling system recall says "manufactured from dec 1991 to jan 1994". My rx7 was manu feb 1992 and I feel should be included in this recall. Mazda however states that there is only 2 recalls on my car. This is my 2nd rx7. The first one I had was manufactured march 1992, one month after this current one. It was exact same car. It was recalled for all 3 showing in the recall database. So what do I do? Mazda says the cooling system is not a recall item for my car. I disagree. Please let me know if I'm writing to wrong place for what I need. Thanks. *Ak
Rear exhaust caught on fire, melting the plastic molding on the bumper and above. *Ak
