general problems of the 2016 Mazda CX-5

From my service mechanic. . . "rear brakes at 8mm/8mm on the right side, but 4mm/6mm on the left. These brakes were replaced 1500 miles ago and should not be showing this kind of wear. Examined brake pads, found evidence of overheating. Scanned vehicle, confirmed no codes from electronic parking brake. Actuated parking brake and confirmed it is engaging and releasing as commanded. Found a technical service bulletin related to parking brake drag on this vehicle. The brake pad damage pattern is consistent with what we observed today. Mazda recommends replacing the affect caliper(s) with an updated version to address this issue. Confirmed by lot number that current calipers are older version. TSB attached. Recommend replacing calipers and rear brake materials. ".

After having brakes serviced brake lights continue to come on. After research from many other complaints they are saying it’s the emergency parking that needs replaced? we shouldn’t have to replace this every time the brakes are replaced.

Back brakes arent gripping, caliper isn’t working been changed quite a few times. Either the abs or electric brakes.

This vehicle has rear electric parking brakes. Some time it's works sometimes it doesn't release the rear passenger side breaks. The rear passenger side brakes make to much noise and brakes pads destroy rotor earlier then others. Mazda dealers doesn't says to much on that and ask for above $1000 repair to change faulty epb clipper. But my research says many people have same complaints with this model by Mazda built-in around 2016. This is safety issue, if I replace brake pads every 4 or 5 months it cost me money. If I don't I cost me my safety.

My brake light and my emergency brake light stays on and they blink constantly while the engine is turned on. They have been like that for at least a year. Both my brakes and the emergency brake both work but I cant get the lights to go out.

2nd time in 40k miles right rear caliper locked up mechanic suggest getting both left and right replaced figuring if one failed its only a matter of time, calipers should last 10 years and 2nd replacement in 4 years, this is a bad safety issue.

Brakes make a jerking sound decelerating from 40 miles an hour or from coming off a freeway ramp. After two trips to the dealership, the jerking sound still persists, the dealership had mentioned it was either the ball bearings or the brake pads were worn out, but somehow the noise is still there. The vehicle still makes stop safely, but we feel that if this is not resolved that this may become a greater safety issue down the road.

Left rear outer brake pad was worn down to the backing plate. After repairs were made, it started smoking while driving. We thought it was going to catch on file. I found a Mazda service bulletin - 04-005/16 - regarding a defective brake control module that controls the electronic parking brake. Why wasn't this a safety recall?.

My epb or electronic parking brake started to malfunction. It will lock up during parking, and driving and stay locked. It will flash malfunction light, and the parking brake light on the dash will come on, and off. Sometimes if I turn off the vehicle for a while, it will again function. I have not been driving this vehicle, because of the issue I am very scarred my brakes will lock up when it is icy or wet, or slick, and I will injure myself or others unintentionally. When I first had this issue, I decided to do research, and it seems to be a very common problem across all 2016 model Mazda Cx-5 with ebp. I suspect the ebp module is defective, and I cannot afford to pay the dealer 1500 to replace this part to correct the safety hazard Mazda originally created. This should never happen to me or the countless others whom own the 2016 model with ebp. A quick google search will result in countless claims of this same issue with the 2016 model.

Last month, my vehicle suddenly applied the electronic parking brake (epb) while I was driving. The epb & related warning lights illuminated & would not release until the vehicle was turned off. After turning off the vehicle, the epb motor could be heard applying the brake to the rear wheels. When the car was restarted, the epb would remain off for a period of time but would then suddenly reapply. I took my vehicle to a Mazda dealer & they determined the calipers & epb motor had failed due to my vehicle not being placed in service mode by the brake servicer. This explanation makes no sense because the brakes were replaced over a year ago (& not since) with thousands of miles being driven since then without this issue arising. I also conducted my own research & found that Mazda has issued at least 3 separate technical service bulletins (TSB) on this issue. The first two recommended replacement of the epb switch & the third determined that defective calipers were the cause and should be replaced. I asked the dealer to save my calipers & confirmed that they are part of the defective batch noted in this TSB. I have contacted Mazda (including their legal counsel) & they are unwilling to provide any explanation or engage in any sort of investigation. As former legal counsel for an automotive company, I believe this presents a serious safety issue for consumers based upon the fact that a parking brake could randomly engage while driving & cause sudden loss of speed/control. Thankfully, this did not result in harm to my family, myself or others. I am certain that this issue is affecting others based on chatboard discussions I have found online related to this topic (which helped me find the TSB). I am concerned that Mazda may have attempted to undertake a silent recall via this TSB where in warranty customers are covered & out of warranty customers are given the 'service mode' explanation to justify their responsibility. This should have been handled as a recall by Mazda.

* the emergency brake module failed and it is available for inspection upon request. * the system failed and randomly turned on the parking break while I was actively driving and paused to make a left of a highway exit ramp. The parking break remained on for ~40 mins while I caused a significant disturbance to the traffic and safety of other around me as the exit ramp began to back up while awaiting a tow truck. Since it was the emergency break we were not able to put the car in neutral and push it out of the way. * yes - arlington autocare confirmed the issue and has since replaced the part. * no there were no warning lamps, messages or other symptoms prior to the parts failure. After the issue was identified I searched online and this seems to be an incredibly common issue with the Mazda 2016 cx5. Multiple other reports exist on line about the failure of this park and the rear breaking system. It is very negligent that a recall has not been filed given the pervasiveness of the issue and the seriousness of the safety concern should the part inevitably fail.

The contact owns a 2016 Mazda cx5. The contact stated that while driving at an undisclosed speed, squeaking noises were heard. The brake warning light was illuminated. The vehicle was taken to an independent mechanic and diagnosed that both the rear brake pads were worn down to 20% and needed replacement. The mechanic informed the contact there were TSB 04-004/19 and 04-005/20 related to the failure and referred the contact to a dealer. The vehicle was taken to the dealer and diagnosed that both the rear brake pads needed to be replaced from normal wear and tear; however, the vehicle was not under warranty. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and informed the contact to schedule an appointment with a dealer for diagnosis. The failure mileage was approximately 22,000.

Ebrake engages on its own when starting up the vehicle. You are unable to turn the ebrake off without restarting the car. The repair shop stated it is a problem with the computer module. A quick search of the internet shows that this is a common issue with this year's make and model. Luckily, the ebrake has not engaged itself yet while driving the vehicle.

I buy this car 2 years ago and 3 months later is starting having problem with rear passenger brakes I took the car to the mechanic and he change disc and brakes pads. A couple months later is starting having the same problem in the same area but this time is was smell burn coming through the wheel I'm stop the car to check was is going on when I check the brakes it was very very hot. I take the car to the mechanic and he told me the epb is bad he changed everything disc, brakes pads,caliper and epb motor. He said try to don't used the epb too much or I'm going to see you again with same problem ??. . . So I'm stop to use the epb for long time. One day I put my car in the carwash one guy hit the epb when he's done with the car im get inside I turn on the car and the brake warning light is starting flashing I say * not again and yes epb get stock. This is make me crazy the epb need to be fix from the dealer please make this common problem a recalls to getting fix for those people got the same issue.

I was driving and was approaching a stop sign so I pressed brake to come to a stop. While I was pressing the brake, the car suddenly revved up and lurched forward. I had to switch the car to neutral gear to stop and then back up out of the way of oncoming traffic.

Parking brake randomly comes on and won't shut off. I started my car and usually the parking brake comes on but after several attempts it shuts off. Today it will not turn off the parking brake. I have tried several combinations involving to push the start button without foot on brake and release brake with foot on brake before the car fully turn on and when car is partly on to off. After 41 minutes waiting (after spending almost 1 hour messing with it) I turned on the car and it works now. Unreliable transportation!.

Parking brake malfunction; dragging of rear wheels especially when turning; sudden seizing of brake while pulling out of parking lot.

Sbs inadvertent activation while pulling into a clear parking stall.

I slowed down in grocery store parking lot. Slowly approaching parking space and applying the brake to stop car. Then suddenly with no reason the car accelerated, jumped the curb and hit building. The whole right side was heavy damaged. I had no control. It was unintended acceleration. I moved the car off the grass from building, this time stopped normally. I am afraid to drive this car because I am concerned it will do this again and I could hurt or kill myself or someone else. Car is still under warranty to 8/12/2019. . Read more...

On July 25 I slowed down in grocery store parking lot. Slowly approaching parking space and applying the brake to stop car. Then suddenly with no reason the car accelerated, jumped the curb. Then car stopped after I hit building fortunately no humans. I was shaken but no bags deployed. I am afraid to drive this car because I am concerned it will do this again and I will be in traffic or near people and I could hurt or kill myself or someone else. There was no warning of any problems. Car is still under warranty to 8/12/2019. Nhtsa had problem with Toyota unintended acceleration in 2010. Please help with unintended acceleration on Mazda. People reported this problem before me back to 2015. This is my second complaint . Nobody called me back and called agency been told your employee he cannot give me information I have to write letter and ask. You are government agency and your motto is people saving people. Please do.

Electric parking brake (epb) control module failure: on June 19 and 20 of 2019 my 2016 Cx-5 with only 18,000 miles experienced a problem with the electric parking brake function. When I would lift the epb switch to set the parking brake the indicator light would start flashing and a warning sign ((p!)) would show up on the dash display. The Mazda dealer did a diagnostic check and determined the epb control module needed replacing. $765 later I was back on the road. This appears to be an inherent problem with 2016 Cx-5s with vins below 781350 (see TSB 04-005/16 of 08/05/2016 attached. ) my VIN is 654830. . Read more...

Started car in driveway 2/10/19, 4 pm �engine sounded like timing was obviously abnormal. Random automatic braking noted when car in motion, within one block of leaving driveway. Immediate inability to accelerate beyond 10-12 mph experienced. Error messages then observed on car dashboard warning sectors: check engine; traction control: tire pressure monitoring; Smart city brake support malfunction-forward scbs disabled. Car unsafe to drive to dealer 12 miles away. Car towed to dealer site 2/11/19 Monday am. Car has 28,330 miles per odometer; service maintenance up to date, as manufacturer recommended. Dealer assessment of cause on 2/11/19 reported as �rats nesting in engine and eating through soy insultation on wiring on engine harness. � repair costs of > $1,500 estimated. It seems that insulating engine component with nutrients attractive to nesting, ubiquitous vermin is a serious safety concern for car owners and users. Any NHTSA guidance on this critical issue?.

This winter, it happened multiple times, in cold weather conditions of approx. -4 to 14 degrees f (-20 to -10 degrees c), when starting the car, the car exhibited the electric parking brake (epb) light flashing, along with the red flashing brake icon and the parking brake icon illuminated on my dash. That warning would be on even the day after, with the car off, until the temperature became warmer.

Took car in for oil change and tire rotation. Less than 10,000 miles, car just 2 years old. Needed major brake job. Total $600. They are telling me because I live at the beach the salt corroded the brakes and it is not covered by warranty. I called customer service and wrote to Mazda headquarters. No one would help me. My concern is will this be occurring every 2 years and are the brakes safe????.

I slowed down in my neighborhood, going about 10 miles and hour, and was coasting into a parking space at about 5 mph in my home neighborhood. It was about 1:15 pm on a sunny, clear day. I was applying the brake to stop the car as I pulled into the spot yet I was going slow and coasting straight into the spot. Suddenly, the car sped up, the brakes had no response, and the car jumped over the curb and ran into two bushes. I did not have my foot on the accelerator, I had my foot on the brake. . . But more than anything, I had no control, it was unintended acceleration. Then the car stopped after I hit the bushes. I was shaken, but no bags deployed. I then moved the car off of the grass, and pulled the car around to the same parking space. This time the car stopped normally. I have 18,168 miles on this car. I have been the only owner. I am afraid to drive this car because I am concerned it will do this again and I will be in traffic or near people and I could hurt or kill myself or someone else. There was no warning of any problem.

I pulled into a parking space and before I could put the car in park it jumped the curb and hit a vacant building. Their were damages to the glass windows and the frame of the build is what stopped the car.

Our 2016 Mazda Cx-5 has 16,000 miles on it and the rear brakes have completely deteriorated. After visiting the dealership, I was told the brakes have rusted out due to the use of the parking break (we need to use the parking break due to where we park). Mazda claims this is a normal �wear-and-year� issue but I do not see how this is as the vehicle has such low mileage. The 2013-2015 Cx-5s suffered a similar issue where Mazda will fix and replace the brakes. However for us, they claim this is our fault although the vehicle is less than two years old.

Dec 9, 2017 - today was first day of snow and first day in my >2 years of driving Cx-5 that I experienced loss in braking, which scared the hell out of me. It happened thrice within span of 20 minutes. Each time I started the car and tried to brake for the 1st time, it wouldn't stop and rolled over for atleast 3-5 feet even when I had the brakes pressed to the floor. Thankfully it was on internal roads and I was at 15 mph anticipating stop signs at intersections. It hasn't happened to me before during last year winter season, so not sure what is causing it.

Parked by the curb at the ft. Lauderdale International airport. I put the car in park and left the car idling with the air-conditioning running. As it was 95 degrees and about 100 at around 8:00 am. There was a shuttle van parked by the curb about 11 feet in front of me. I had to exit my car to talk to the driver in the car behind me. I walked to the car behind me and started talking to the driver. I glanced back at my Mazda cx5 and it started rolling forward. I ran up to the car and got the door open and stepped on the brake. The brakes did not engage. I repeated stepping on the brake several times and the car would not stop. I got in the drivers seat to shift the car into reverse and keep my foot on the brake pedal. The car would not shift into reverse. And by this time the Mazda had pinned to the shuttle van a lady who was trying to unload her luggage. On the sixth attempt to shift into reverse the shifter finally moved into reverse and by standers came to the aid of the lady that had been pinned to the shuttle van. Airport security and the broward county police took the statements. The lady retrieving her baggage declined medical attention. When I checked to see what the police were reporting they did not acknowledge that I was attempting to stop a runaway vehicle. The report said that I failed to put the car in park and left it in drive. It is not possible to get out of a car that is idling and in gear without the car moving forward or backward before you can even get all the way out of the car. This incident happened about mid July in 2017. Near the end of June this year while in my driveway I left the car idling and in park, exited the car walking to the rear of the car and it dropped into reverse. Got back in the car and shut off the engine. July 2017 the local Mazda dealer inspected the vehicle and could not find as problem. Not unlikely with an intermittent electrical anomaly. There were no prior warning lamps in either incident.

While driving on a slope with bit of curve on a highway when I applied a mild brake to reduce the speed, the car abruptly moved straight left and goes off road. The brake and steering didn't respond immediately for few seconds and the car keep going down off road on a very rough terrain. Luckily it stopped few meters before a sharp fall.

The electronic parking brake locks the rear wheels as designed. The toggle switch that activates the brakes has direct control that does not go through the anti-lock brake system or the on board computer. Once the parking brake is activated, at any speed, there is a two step process required to release the brakes and allow the rear wheels to rotate. In my case, the accidental activation of the brake switch at less than 10 mph locked up the rear brakes and the car came to a very abrupt screeching halt. If I were going faster when this occurred, the brake lock up could have led to a loss of control of the vehicle.

Mazda has a TSB 04-005/15 that needs to be expanded to include the 2016 model year; currently it only covers model years 2013-2014, build before oct 9, 2013. My 2016 cx5 (with less than 30,000mi. ) has experienced the same failure as described by Mazda's TSB (excessive outer brake pad wear with little inner pad wear). Madza service managers are not honoring this TSB if the the VIN is after the effectivity date. Sorry I don't have any photos at this time to document the problem. I have attached Mazda's TSB 04-005/15 which describe the problem and their proposed solution, and how they have extended the vehicle warrenty period for having this issue repaired.

Bought new car; driven less than 400 miles; thudding noise noticed pretty much from day 1. Got louder. Took it in. The right rear hub, and bearing assembly were faulty and had also damaged inner disc. The dealer fixed it but assurance of "faulty part, doesn't happen with Mazda" now does not ring true. This could have been a safety issue for me had I been driving long distance, for which this car was purchased.

The brakes have been faulty since I've purchased the vehicle new. There is a loud scream that is not from dust or wear. There is a manufacturing defect in the brakes. The brakes are very loud every time I apply them. I am very concerned about this, have contacted the company before.

While attempting to pull into a parking space with a 2016 Mazda Cx-5 (7000 miles) all of the warning lights on the dashboard lit up and the car started accelerating on its own (unintended acceleration). The brakes would not work! in an attempt to avoid the car parked in front of me I swerved to the right, unfortunately I hit the parked car with enough force to moved it about 12 feet forward. My vehicle continued going up an over a curbed median and finally came to rest approximately 100 feet away with enough force (brakes finally worked) to knock my glasses off as my head jerked forward. Vehicle was towed to the dealer and was examined and deemed "working as designed". Supposedly, information was sent to Mazda USA engineers, the dealer states they found nothing unusual but have never given me a written report stating so even though I have requested it on multiple occasions. The dealer recommendation was to fix the damage to my car ($4400. 00 worth) and then they would install a "special black box" and drive the vehicle for a few days. After driving the vehicle for 3 days, the dealer still says that nothing is wrong with the vehicle. We feel that Mazda corp should take this vehicle back and inspect it thoroughly for unintended acceleration, as we do not feel comfortable driving this vehicle anymore.
