What owners say about the power train

Verbatim from NHTSA complaints, newest first
“Any time the vehicle has been sitting with the engine off and has been given enough time to “cool down”, upon starting the vehicle and switching from PARK to DRIVE, the vehicle will violently lurch forward while attempting to reach 2nd gear. This is dangerous behavior that is not normal for any vehicle. There is clearly something wrong with either the transmission or the way the software communicates with the transmission. When the engine is within normal temperature it doesn’t display this dangerous behavior. A similar TSB was issued for the 2nd generation of CX5s but not for this generation of CX5s”

“The contact owns a 2016 Mazda CX-5. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the vehicle, and the message “Smart Brake Malfunction” was displayed. The vehicle was taken to an independent mechanic, where it was diagnosed with catastrophic brake caliper failure. The contact was unsure if the vehicle needed to be repaired. The vehicle was then taken to the dealer, where it was diagnosed, and it was determined that the passenger’s side inner CV joint had failed and needed to be replaced. The vehicle was not repaired. The dealer informed the contact that the vehicle could not be driven due to the severe failure. The manufacturer was not made aware of the failure. The approximate failure mileage was 125,385.”

“I was driving on a city street and slowed to turn right onto a driveway at at a private residence. As my car entered the driveway and near the end of the right turn, my car had a sudden unintended uncontrolled acceleration, continued the turn, went over a low hedge of shrubs on the right side of the driveway, continued down a short rocky incline, and landed on a large rock where the car stopped.”

“About a month ago, started hearing a whining noise from the automatic transaxle when driving at different speeds. The more speed, the more noise you hear inside the vehicle. It occurs with all types of driving, acceleration, deceleration and steady speed. Took my Mazda CX-5 into auto experts and found there is a Service Bulletin regarding this issue in 2013-2016 Mazda CX-5's. There is a damaged bearing in the transaxle due to improper configuration of the transaxle case. There needs to be a recall for this issue, not just a service bulletin. I cannot afford a new transmission and replacing the transmission with a like for like or used transmission, there is no guarantee the issue won't come back.”

“I was driving on the freeway, going 60-65mph for about 10 minutes. All of a sudden, the engine went from ~2k RPM to ~4 RPM. The speed stayed the same. And then it happened again a few minutes later. A few days after this incident, while driving on the freeway, going 60mph, the car refused to go past 60mph. This also happened ~2 weeks prior. This would have caused an accident had I needed to speed up to avoid an issue but my car refused to go any faster on a flat road.”
