On Feb. 9, 2023, I started my vehicle and lots of warning indicators lit up the dash of my well-maintained vehicle. Check Engine, ABS, TPMS, SBCS to name some of the warning lights. When I took my car to the dealer, they told me the left front wheel speed sensor had mechanical failure and would need to be replaced. Said the car's antilock brakes wouldn't work without it being replaced. My car also has the automatic brakes to prevent collision and stability control systems which are dependent on wheel speed sensors' function. My vehicle mileage was 59307 when I took it to the dealer. Over $600 repair bill.

After the rear brakes were replaced there was a terrible grinding noise when first driving until the car warmed up. It did not happen when first replaced in the summer but when it got colder it got worse. Turned out to be the same caliper issue that was recalled in previous models but no recall for the Cx-5

I was trying to park my vehicle in a soccer field parking lot. As I slowly turning right into my spot at about 3-5mph, my foot was lightly depressed on brake pedal and about to come to a complete stop, the vehicle suddenly made a very loud engine sound (my foot was still on the brake pedal and not on the gas pedal) as the engine rev up for about a second or two then accelerated forward jumping the curb and hit a big fence pole which stopped the vehicle. The vehicle felt like it sped up from 3mph to 30mph and I had no time to react. The front passenger side badly destroyed and the vehicle is totaled. The car was five years old and about 75K miles. It is very safety concerning and should be seriously look into.

I was parking my Mazda CX5 in a spot at a shopping center and when I touched the brake with my right foot and went to shift car into park, it suddenly accelerated full speed, making a vroom sound, jumping the curb and smashing into a brick post (luckily I hit the post and not a person!). I don't know if it's a transmission, brake or accelerator issue - but there is definitely something wrong. I did not hit the accelerator instead of the brake. At first I thought it must be me, somehow, someway, hitting the accelerater but I never really believed this. Today, April 26, 2019, the same thing happened! luckily, this time the car jumped the curb and I hit a tree, leaving a small dent in my hood. Again I heard that vroom sound, and just thought - oh no, not again!

My foot was solely on the brake as my car was coming to a stop in a parking space. Then suddenly with no reason, the car accelerated, jumping the cement tire stopper, hit against the concrete parking column, went down a slight hill and hit another concrete parking column before stopping. The whole right side (passenger side) was completely totaled. Fortunately I only had bruises and no other cars were damaged. This is a serious safety problem and should be investigated.

The front brakes on my car would not pass pa state inspection because of severe rust on the piston side of both front rotors. The outer surfaces of the rotors were fine. All of the pads were at 50% for wear. The vehicle is three years old, bought new, and has 38,000 miles of mixed driving. The dealer contacted the Mazda district manager and he refused to do anything about it and considered what I had as normal wear. I replaced the rotors and pads myself and was surprised at the improvement in stopping distance. Since this was happening over time, I was not aware of my loss in braking. After I replaced my brakes and personally called michael konzel, the Mazda district manager, he told me that this was considered normal and not a Mazda issue. I offered to send him pictures, but he said that he did not need them. The vehicle was stationary at the time, but driven daily.

While driving through stop and go traffic near a traffic light on a downward slope (maybe 10-15 degrees), I attempted to apply the brakes in order to come to a stop. When doing so, the brake pedal was being applied normally but the vehicle wasn't slowing down like it normally does. As a result, I pushed down on the brakes as hard as possible and while the vehicle slowed down more than it previously was, it attempted to lurch forward more and more. I noticed that the rpms were slowly getting higher while I was in the middle of applying the brake pedal as hard as possible, but the vehicle was coming increasingly close to making contact with the vehicle in front of me. Due to the vehicle being close to being physically stopped already, I placed the vehicle in park as quickly as possible and the rpms for the vehicle immediately climbed all the way to the red-line (I believe 6,500 rpms) and then returned to normal. Throughout the remainder of the trip (another 5-10 miles), the vehicle exhibited no noticeable issues. I called the local Mazda dealership to see if any problems regarding the transmission were currently being investigated, but I was told that no recalls were currently open for a transmission problem.

I have a braking issue. When I brake my car at low speed, I rarely have any issue and my brake works well. But if I drive at a higher speed (>55mph) and brake relatively fast, I will feel like my foot is pushing on both brake and gas pedals, and my car will not slow down as it's supposed to. It feels like there is no significant force of friction between the brake pads and drums. The feeling of braking is not smooth either as if I was pushing the gas pedal at the same time. I almost hit the cars before me twice. This issue can be resolved with quick brake pedal relief and subsequent stepping on again. I may need to repeat this effort several times before it works normally. I believe there is some mechanical problem with it. I drive very carefully on high way now.

Braking I would have a braking issue every time I drive over a little indentation (a horizontal line that is slightly on the road used for a water passage). When I drive over the water passage my vehicle would not stop and even thought I step on the brake pedal hard, it would just keep going and you can feel the brakes just slipping off the brake pad or something like that.

Leaving an above-ground parking garage, the city brake assist feature engaged twice, without warning. The car came to a sudden and complete stop and the wheels locked up. There were no cars or other obstacles in the vicinity that would have caused the city brake assist feature to engage. When the feature engaged, the car was going about 5 mph, on a slight downhill (the decline was simply from the parking garage), and it occurred during a straightaway section of the garage (e.g., not while going around a bend).

Our vehicle is equipped with the "smart city braking" feature that automatically prevents collisions at low speed. This system triggers the brakes and brings the vehicle to a stop when an object is detected in front of the vehicle. This system has been triggered by steam clouds coming out of sewer grates and has brought the car to a complete and very unexpected stop several times. No real "object" was behind the steam cloud / yet because of the way the system is implemented it detected an object and activated the brakes. This unexpected braking can quickly bring the car to a complete stop and could result in serious property damage or injury. We pass by an area with multiple sewage grates releasing steam and this system is becoming a safety hazard. We have been lucky enough not to have someone behind us when the system is triggered - but it is only a matter of time before the braking triggers in heavy traffic.

This is the second occurrence of the same issue, but while driving the vehicle at highway speeds, all dash lights illuminated (check engine, turn signals, temp warnings, etc) simultaneously and the information screen displayed an alert "engine inspection required". the incident also resulted in a loss of power steering/heavier-than-normal steering effort and brake warning indications, on the first instance (July 10, 2014), Mazda roadside assistance was contacted and the vehicle was towed to the dealer with no fault/cause found. On the second instance (July 15, 2014), the vehicle was driven directly to the dealership. Technicians were able to diagnose the issue to a loose ground connection in the passenger front fender well.
