The check engine light came on and the vehicle has 61,000 miles. The dealership determined that a new heater core is needed and there have been several service bulletins issued on this part. The error code showed po11A. The dealership wants to charge $2,367 to replace the heater core. Mazda corporate was contacted and since the vehicle is out of warranty they are not will to assist in any way. The reference number for this complaint is 1-3153481645. The technical service bulletin said the average mileage this occurs is 39,029 miles. I realize this may not be a safety issue but this is something Mazda should stand behind. There is no accident or injury associated with this. There should be a recall if the part fails this early in the life of the vehicle.

Driving normally, suddenly at an on-ramp, car would no longer accelerate. I hit the gas a couple times and engine just revved, and the car was jerky as if struggling to change gear. Anything over 3,000 RPM it would not drive. I also noticed electrical problems with radio and lights at the same time. Thankfully, I was able to coast to pull over. Turned off car and re-started. Test drove the vehicle around the area and it happened again at over 3,000 RPM. Luckily this didn't cause an accident.

While cleaning our 2015 Mazda Cx-5 that was parked in our driveway, I ran the seat forward to vacuum under it. When moving it back, the left side of the seat would not budge. When we inspected all over underneath the seat we could find nothing impeding the sliding mechanism. The car had to be towed to our mechanic as it was unsafe to drive with the seat all the way forward. After some research and hard work, our mechanic was able to remove the seat and sliding component and replace the entire power slide unit (part # kdy2-88-4foa power slide lf-S ) for the driver's seat. He found that the cable to the power unit on the left side of the seat had broken. The right side appears to be weakening as well. Through his research, our mechanic found a tsb bulletin on this exact safety issue. (tsb #09-006-16) he explained that the ntsb had told Mazda to correct the problem in subsequent model years but that leaves us, and probably others, in the lurch for a safety issue that shouldn't have happened.

I was driving down the interstate at normal speed at 7pm North of birmingham, al. It was dark and a couple vehicles were pretty far ahead of me. There was nothing above the car (no bridge, tree, etc.) all of a sudden, I heard what sounded like an explosion or gunshot. I got off at the nearest exit to examine the vehicle and discovered that the sunroof had exploded. The sunroof glass exploded upward and outward. The glass protruded upward and shards of glass were blown out onto the roof of my car. There was no sign of any foreign object having hit the car or sunroof. Luckily I had the shade closed; otherwise, glass shards could have been thrown inside the vehicle and injured me. The noise was so loud that I was also lucky that I didn't panic and wreck the vehicle. After doing online research and finding many similar stories, I believe the sunroof glass was flawed or installed improperly. I reported it to Mazda and they told me it was environmental and that I should file it on my insurance. I told them that I consider this a safety hazard and that they should investigate it, but they refused and instructed me to file it on my insurance. When I took it to hiley Mazda in huntsville al, they wrote "imploded" on their damage estimate when I very clearly told them it "exploded" outward and showed them my photos.

We were driving across Wyoming on the interstate with the cruise control on at 75mph. Suddenly there was a violent shake in the car like the engine was locking up. We tried to pull off the highway and it did it again as we were pulling over. When we got the car stopped the check engine light was on and a message on the display that engine diagnostics were required. I called the dealer in ft collins co and my dealer in denver but they said they could not tell me what to do. I drove the car back to denver very slowly with the check engine and warning message on the dash and it ran okay. My dealer could not look at it for a week and when I took it in the warning lights had gone off. The dealer said there were no codes and nothing they could find wrong. I called Mazda and they had me take it to another dealer and again there were no codes for it. We are scared to drive the car. It has sat in our garage the past couple months except for the trips to the dealer. If we had been in traffic I think we would have caused an accident.

While driving the lane change radar warning system indicates a vehicle when there is none. For example I can be in the right lane on a multi lane highway and the light on the side mirror will illuminate indicating a vehicle in my blind spot when there is none. It is sporadic and mostly does this on the drivers side but has also done this on the passenger side

An interior panel (console cover) adjacent to gas pedal has come off while the car was on the road, once to my wife and once to me. It interfered with the driver's ability to lift the foot off of the gas pedal. I complained to the dealer that it appears that the panel was designed to have 3 spring clips to retain it, but the panel only had one. (my Mazda CX5 has several clips on a similar part). The dealer simply snapped it back in place after the first occurrence. After the second occurrence I suggested that it was missing a retaining clip. The dealer ordered and installed a new panel. It came off while I was on the highway, once again interfering with my ability to lift my foot from the accelerator pedal. I observed that the new panel has only one retaining clip, just like the original. I consider this to be a serious design flaw posing a significant hazard, especially to an inexperienced driver.

I bought this car new in May. Within the first month, the car wouldn't start I bought the car in to the dealer and they replaced the batteries on the fobs. Last week, I noticed the driver's side window trim front and back doors was melting. I called the dealer, bought it in and they took pics, said they would contact Mazda rep and sent me home. On Saturday, I drove to a store approx. 10 miles away and when leaving for home, my car wouldn't start again. I finally got it started after multiple tries. While driving home I noticed the blind spot monitoring on the drivers side was flashing and there were no cars next to me. I left the car parked for the rest of the weekend but on Sunday noticed the melted spots were worse. I contacted the dealer on Monday and brought it in. They are saying something on our house or around it is causing the melting, however, my wife parks her 2015 Honda CR-V next to mine and there is no melting happening to her car. All the other vehicles owned and parked in the same driveway for the past 15 years do not have this issue. I also submitted this info to mazdausa.com but have not heard back.

Driver side view mirror will vibrate while driving and hard to see the objects properly in the mirror. They had the same issue on 2013-2014 vehicles. When I contact Mazda dealers, they say there is no fix for that and getting away without trying to fix it. Clearly it is a safety issue.
