The break booster went out without any warning or indicators while driving almost resulting in a collision. There are no warning lights on the dashboard.Owner report · Service Brakes · Jun 2026
Braking inconsistently - sometimes easy to stop, sometimes hard. I had brakes looked at, and the man said it was the brake booster. He googled it, and found a recall online and told me to take it to my dealer. It doesn't look like there's an active recall - but a lot of complaints. What's going on? This is going to be expensive. My college age daughter drives that car. Do they have to have a severe accident to get that fixed? I can't afford to fix it right now.Owner report · Service Brakes · Mar 2023
While driving the vehicle went to stop car and was unable to stop brake pedal was hard as a rock luckily I didn't hit anything or anyone. upon further research it seems that this model has an issues with the brake booster failing causing exactly what I experienced. As it turns out I did not qualify for the extended warranty on the brake booster due to a agreement between you and mazda my issue is it should be life of the model with no expiration date due to the fact it can happen at any moment. Luckily my family wasn't harmed and luckily someone else's family wasn't harmed because of this failure. My vehicle only has 86,000+ miles.Owner report · Service Brakes · Sep 2022

Brakes not working due to brake booster problem which was brought to the attention of Mazda. Mazda and the transportation authority agreed on an extended warranty which is no longer in effect. There have been many more complaints for this same problem, yet a recall has not been listed for this vechicle and alot of people are paying out of pocket. I already brought this to the attention of traffic safety and never received a return reply. Brakes are squishy than you end up having to put brakes all the way to get car to stop. People are unaware of this major brake and safety defectOwner report · Service Brakes · Aug 2022
Driving and brakes would not work without pressing really hard. The problem was reported before on these cars and continue to be a problem. https://www.carcomplaints.com/Mazda/CX-9/2010/brakes/stiff_difficult_braking.shtml my car has been in 2 shops for about 3 months now. They had to replace several parts in the braking system. Than the rear brakes completely froze up and towed to Mazda out of Greensboro NC.Owner report · Service Brakes · Jul 2022

The water pump failed and leaked coolant into the engine, causing motor damage which requires motor replacement. There was no evidence of any failure until the vehicle overheated while being driven. This is a known design flaw of the engine design but no recall has been issued.Owner report · Engine · Apr 2022

The AWD system failed leaving the car dangerous to drive in rain and snowy weather. Car is still stuck in my driveway as the front wheels are spinning and no power to the rear wheels. My Mother's AWD with similar M+S tires drove out with no problems. Waiting for the snow to melt to be able to take my car into the shop. Reading online this seems like a known Mazda issue.Owner report · Power Train · Dec 2021
My vehicle completely shut off while idling in park with no prior warning to anything being wrong. Put coolant in since the container was empty. Replaced thermostat, but vehicle was still overheating. Had it towed to Flow Mazda of Fayetteville and had them run a diagnostic. They determined that coolant was leaking into the oil due to a broken water pump. It was estimated to cost approximately $5,000 to repair with no guarantee that it would fix the problem. They pulled 4 sludge codes. There is currently a lawsuit against Mazda for this specific problem that was filed in 2019.Owner report · Engine · Jul 2021
