Engine and engine cooling: cooling system
- What is wrong
- The radiator cap pressure relief valve release pressure is set too high. This can cause the coolant to reach temperatures that exceed the thermal design limits of some components of the coolant system. Should this occur, engine coolant can leak collect on top of the engine.
- Risk
- If engine coolant leaks onto the hot engine exhaust manifold from the top of the engine, an engine compartment fire can result.
- Remedy
- Dealers will inspect the vehicles and if any vehicle exhibits coolant leakage or if the coolant level has dropped to the point where the coolant loss would be sufficient to trigger the coolant level warning system, components potentially subject to deterioration from overheating would be replaced. These parts include the water pump bearing housing, the water level sensor and radiator upper hose, the thermostat gasket, and all water hoses located above the engine. In addition, all vehicles in which those components are replaced would also have the cooling system and other systems that carry flammable liquids checked to make certain that engine overheating had not caused any problems in those systems. Any identified problems will be repaired. The radiator cap, filler cap, and filler cap body of all recalled vehicles will be replaced by newly designed parts.

Most recent owner complaints, unedited.
The consumer received a recall the federal safety agency#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
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.
3.8l engine would continually overheat while driving. Dealer contacted. Feel free to provide any further infromatio information.
94 v 094 000/engine cooling system : this recall notice was received. Contacted manufacturer concerning other recalls founded on the web, they informed that vehicle had two recalls that were already completed, and recall concerning cooling system did not show up on this vehicle. Dealer was not notified at this time. Feel free to provide any further information.
94 v 094 000/engine cooling system: a fire started in the engine compartment while driving 30-35 MPH. Dealer and manufacturer have not been notified. Feel free to provide any further. Information.
The engine had and overheating problem which lead to excessive heat deteriorating the engine seals, a new engine was installed, the new engine developed an oil leak, the consumer requests reimbursement. Nlm
Vehicle been experiencing problem with engine failure. Engine been replaced every 45,000 mile of wears. Engine needs to be replaced again. Dealer notified.
Defectively designed computer chip caused engine to stall when A/C unit is operating. Mazda refuses to repair under warranty. Nlm
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 [xxx] 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 #[xxx] 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
