The water pump went out with no notice or warning, flushed all the coolant/water into the engine and failed. Over a $2K repair for a known engine defect with active lawsuits out. A Mazda water pump lawsuit alleges 2007-2016 Mazda CX-9 and 2009-2013 Mazda6 vehicles are equipped with pumps that suddenly fail and cause catastrophic engine failures. The proposed class action lawsuit alleges the vehicles lose engine power and fail to accelerate and maintain speed. The vehicles also allegedly can't readily control steering and cannot fully engage the brakes. The plaintiffs claim the vehicles are at risk of serious crashes because Mazda has failed to disclose the alleged water pump defects. Please investigate for a recall asap!

Water pump failed and impacted my engine as well. I just brought my car in as well 10/20/2020 no mention of this issue. Beginning in 2007 and continuing through the 2016 model year, Mazda has incorporated its mzi cyclone engine (the 'cyclone engine') into hundreds of thousands of vehicles, which include the Cx-9 for model years 2007 through 2016 and the Mazda 6 for model years 2009 through 2013. The cyclone engine contains an internal chain-driven water pump, which means the timing chain is connected to the water pump and provides the power the water pump needs to circulate coolant through the engine when the engine is running. The chain-driven water pump is located internal to the cyclone engine, behind numerous engine components, including the timing chain cover. Unbeknownst to purchasers and lessees of these vehicles, the cyclone engine contains a defect in design, manufacturing, materials and/or workmanship that causes the water pump to suddenly and prematurely fail well-before the end of the useful life of the engine, which leads to catastrophic engine failure or a costly replacement due to the water pump's inaccessible placement in the engine. When the water pump prematurely fails without warning, coolant is able to leak from the water pump into the oil pan and/or other engine components, allowing it to mix with the engine's oil. The mixture of engine oil and coolant circulates throughout the engine, leading to destruction of the engine. Despite having knowledge of this defect, Mazda continued selling defective vehicles, failed to disclose the defect to owners and lessees, has not issued a recall, and has not remedied the issue and/or compensated owners and lessees of the defective vehicles.

The radiator failed internally with no warning, no leaks no engine light nothing, mixing antifreeze into the oil and destroying the engine. My machine informed me that there was no way of me knowing this was happening and its faulty the way they make the radiator it causes this to happen. Now my radiator is bad and my engine. I was driving and suddenly a noise started then power went and pulled over and wouldn't start again. No warning nothing. No leaks no engine light prior.

I was driving on the highway when my sunroof exploded, showering glass inside the car. I did not see anything hit it. The breakage seemed to be spontaneous.

I was driving at approximately 60 mph when my sunroof exploded. There were no other cars around me that could have thrown a rock my way. It just sounded like something landed on the top of my car and then I saw glass flying off my car from rearview mirror when I realized it was my sunroof!! scary as heck!!

My vehicle seemed as if the transmission was slipping between gears on the highway it would take forever to switch into higher gears for higher speeds then when slowing down it would jerk and then finally stop or if I was in traffic where I didn't need to make a complete stop it would jerk to slow down and skip gears and jerk to speed back up while on the high way traveling at normal speed with cruise control set it went from 6th gear to 4th gear for no reason at all! then it started making noises sounding like both the front and back end first you would only hear them when turning right or left then started hearing them in reverse then you heard them while driving all the time on the highway back roads and parking sounded as if my tires were going to fall off! I contacted carmax because that's where I purchased the car in March of 2017 it's now agust 2017 and told them what was happening they lied from the initial phone call but that's besides the point they had my vehicle for a week saying they were looking at it thoroughly to make sure what they found in the rear differential was the issue they assured me it was told me if I heard the noise bring it back asap as I was driving the vehicle home it was still experiencing the same issues we tried to call them immediately but they were closed we called them that Monday and couldn't get anybody on the phone so we left a message we continue to call them for two weeks before they finally gave us an appointment to bring the car and I could not drive my car for the two weeks that I had it in my possession because I was told through my extended warrantee that driving my vehicle while it was still damaged would void my warranty the day after we drop my car off back at carmax I was called and told that the date it was pulled out of the garage on the original repair date 3 weeks prior that the tech noted to bring to Mazda

I have brought the vehicle to 2 different Mazda dealers to fix this recall. They have inspected the issue and determined it not to be urgent. The last time, Nov 16, 2016, I was told the parts would be ordered and I would be contacted to set up an appt for repair. No contact yet. I am frustrated.
