Oil cooler hoses rust out at fittings and leak oil uncontrollably. One search of any RX8 forum and you will find all years are effected.

The external oil lines and connection fittings for the rotory engine lubrication points and cooling have corroded away form road salt in Minnesota. Driving causes engine oil to be sprayed on front wheel and brakes causing front brake failure and possible engine fire problems. The corrosion was so bad that each attempt to fix an oil leak ended up braking more corroded oil fittings off. The total repair in 2017 ended being over $1,000 dollars for just parts plus labor. Mazda has previously paid to fix all Mazda Rx-8S sold to people in Canada because of road salt corrosion failures of these same oil lines. Why doesn't the usa have consumer protection like Canadian citizens have! I paid a repair shop by me $1,037.81 for the repairs. The mechanic lost about another $1,000 in after market fittings and hoses plus time, but each fix broke more fittings. He finally bought all new factory parts and sold them to me for cost and only charged us for about 2 hours labor. Tony beck, S auto repair in pineisland mn just couldn't charge anyone what it really cost him. Us Rx-8 owners are getting screwed by you not recalling this oil line failure problem. These oil lines and fittings go all around the outside of the engine and are high pressure 1/2 inch id hydraulic lines. How can oil spraying front disc brakes and engine compartment not be a safety issue! steve w. from Minnesota, we have lots of road salt just like Canada, that's why the I-35 bridge fell down. Not safe to drive with these salt corrosion caused oil leaks! caused massive oil leaks that can allow engine

I purchased a used 2005 Mazda Rx-8 from a dealer. Signed a warranty although there were not a buyers guide or a used car sticker displayed anywhere on the vehicle. The vehicle originally belonged to Mazda bommarito as evidenced by the faded residual imprint of the bommarito lettering that had beem removed likely due to being unwanted inventory. I knew ahead of time that this particular vehicle has a rotary engine that requires standard maintenance and care which I have been performing and documenting along with all recalls. These include- let the engine warm up, regularly topped off all fluids decarbed and cleaned sensors etc internal maintenance care/break in period and replaced spark plugs/ leads with factory genuine oem first hand. After owning it less than a year, with only 50K miles on it, it began to run very poorly. I had the vehicle diagnosed and have documentation and records of work from several independent mechanics, shops and official Mazda dealership(bommarito where it was originally transported from to the neighboring dealer) im paying $8,000 for at it and drove it for less than a year and in spite of regular upkeep it lost compression in its rear rotor. II have the extended warranty notice from Mazda that covers rotary engine core replacements. However since its "used" it might not be covered by my states lemon law. There are 1000's of owners dealing with the same issues on behalf of Mazda. I mailed the subsequent ownership notification to the Mazda importer to transfer the records of the previous owners on a lease purchase which I have documentation of although the dealer would not give me any info about the coupes histroy which seems dishonest.. the dealership is not entirely at fault. Mazda is too. Have all this in paperwork. I am awaiting a return notice from Mazda about transfer of warranty from the previous owner(s) documents are below.

I believe safety and emissions recall 0516J is causing my car to turn off while in motion, it can be in neutral or in gear. I called Mazda Corp and told them the vehicle turns off while in motion and believe it's cause by the recall; they said that they do not have a solution at the moment and did not suggest anything but wait. This is a daily driving car and I can not afford to call out of work because of the safety of this vehicle. I would suggest a courtesy vehicle while this recall is being fixed.

My steering wheel is turning to the left on its own and it is difficult to turn to the right. I have researched online and I'm not the only one having the problem. I don't feel safe driving my vehicle and I am disappointed in the quality of parts. Issue 2: after the first recall on my vehicle, my motor is giving me issues again after being replaced 40,000 miles later. It turns off at idle and has problems starting. I fear this might be a safety issue.

There is a flaw in the Mazda RX8 engine. It is why they stopped making them in 2011. The engines have bad apex seals. As a result - the seals blow around 70 thousand miles and the engine is useless. Mazda replaced my engine in 2011. However - it does not solve the problem. The engine still shuts down in traffic. This is extremely dangerous. When you are coming to a stop or slowing down the engine will just shut off. It has also shut off when I attempted to pass in the left lane while accelerating on the highway. It also has something called a hot non-start - this means - it will not start when the engine is hot. You have to wait 20 minutes for the car to cool before it can start. If there is no emergency lane when your car shuts down - you are in trouble and in a very dangerous situation, . I have been stuck numerous times in traffic and then the car unable to start. Also as a result of this hot non-start- you have to fuel your car with it running or you will have to sit and wait at the gas pump for 20 minutes before it can start. This has occurred before they replaced my engine from 2009 thru 2011 and now with a new engine from 2012 thru 2015 they also need to be investigated for fraud. I leased my car for 3 years. I then purchased it and financed it for 5 years in 2008. Mazda knew these engines were flawed - but they were still selling them to people when this engine issue has been around since 2005. The car is dangerous to drive. Also - the apex seals can blow when you are driving the which means the car will shut down in traffic as well. I am not alone - search Mazda RX8 engine issues on google - everyone has the problem.

The contact owns a 2005 Mazda RX8. The contact stated that the oil coolant line exploded and spilled oil onto the brakes. As a result, the braking distance and time was increased greatly. The contact also stated that it was difficult to stop the vehicle. The contact stated that there was no warning prior to the failure. The contact stated that there was a metal piece that became fractured. The contact spoke with the manufacturer and was told that there was no warranty or recall for the part. The VIN was not available. The failure and the current mileage was 91,239.

I went to start my RX8 and it would not start. I called aaa to have it jumped, thinking it was a battery problem. The aaa employee sent to jump the car could not jump it and I had to tow it to my mechanic the next day. My personal mechanic looked at it and said it was a specific problem with the engine that was covered by an "extended warranty" Mazda issued because the 2005 rx8S had so many complaints about this particular problem. Instead of doing a recall, Mazda does extended warranties. They did the same thing with the clutch pedal bracket, which I had to jump through hoops to get the dealership to take care of it at no cost to me. They always want to charge, even when it is something covered by a warranty. So, my husband had the car towed to the nearby dealership. Automatically, they tell us we have to replace the battery because they need to do a diagnostic test to find out the problem. Battery $185 with labor and $150 for a diagnostic test. Then, we are told that only if they are able to prove that it was a specific problem covered in the warranty that Mazda would cover it under the warranty. If they find it is not that specific part, we will have to pay out of pocket. I was told by my personal mechanic it was that particular issue which is covered by the warranty, but of course, Mazda wants to do their own tests. My car has less than 50,000 miles on it and it is ridiculous that I would have to replace the engine for $4,000 when a quick online search shows that this is a very common problem with this specific car. I think Mazda should have their feet held to the fire and do right by their customer.
