Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2018 Mazda CX-5 owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owned a 2018 Mazda CX5. The contact stated that while his wife was driving at approximately 35 - 40 MPH, the power steering assist and brakes failed, causing the vehicle to crash into trees. None of the air bags deployed upon impact. All of the warning lights were illuminated. The contact's wife attempted to turn off the vehicle, but it would not turn off. The fire department had to disconnect the battery to turn off the vehicle. A police report was filed. The contact's wife was later taken to the hospital for injuries sustained to her knees. The vehicle was towed to a tow yard and was not yet deemed totaled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 35,000.
Unintended acceleration incident. I entered the parking lot of a business where the Salvation Army is located to drop off a donation. The parking spaces were on the left side. As I pulled into a parking space and was in the process of parking, the vehicle suddenly lurched/accelerated forward unexpectedly and struck the concrete wall of the building. The airbags did not deploy despite the frontal impact. No one was seriously injured, but my husband, daughter, and I experienced soreness the following day from the impact. Thankfully, I had chosen a parking space in front of a concrete wall rather than the glass storefront windows, which could have resulted in far more serious injuries or damage. I contacted my insurance company, and the vehicle has since been repaired.
Certified Mazda cx5 sold with faulty wheel bearing and had to be back in service less than 24 hours from purchase. They failed to replace the piece of engine after 35.000 maintenance and another dealer found 5 areas that needed work 3 weeks later. Brake warning system went off took5 days to determine it was a dead switch and replaced exactly one month later Brake system warning goes off after car was In park and off for 25 minutes at the airport. I was told that I was fine to drive it despite the manual clearly saying do not drive if Brake warning lights go on. And it was supposed to have been repaired. The dealership expected me to believe that a rubber mat set off the high tech Brake system this is ridiculous They bought back car did not return the 5000 down payment or 14000 trade in and refused to honor the store warranty of buy back for life KBB 125 of trade in value. …
The engine has a massive oil leak that seems to be more common than Mazda will admit. The safety-related issue is the oil pours out like pancake syrup which can be bad for other drivers, the environment and cause road asphalt to break down at a rapid pace. I also don't have a warranty. When I consulted Mazda all they wanted to do is charge me $7,000 for a new engine from all the research I found on the internet. This is a problem that is affecting many people because when you only have one vehicle and have no way to make money. Most people will just keep adding oil to keep it going. Many customers are left with a car payment with no way out and a car they can't really drive other than short distances. Something needs to be done to hold them accountable for this common problem. I don't know anyone that can afford a $ 40,000-yard brick. …
I find I have to put my foot down on the gas pedal to the floor to make it literally go at times. Ive heard this cloaking noise several times like its getting ready to conk out. The brakes seems to me don't stop as they should at times I have to go in hard on the brake pedal. The air conditioner does not blow cold an see where previous owner had same issue 2 yrs straight from looking the the service invoices that was left in the truck. The sensor detection does not always work to let me know car/person is around. Coleman Taylor Transmission informed me that this thing does have a issue, the rpm are not as they should be. When I took it back to Kia Gossett about the brakes the used mgr drove it made it seems there were no issues as well as Norcross Mazda. Previous owner invoice show brakes were a concern as well. …
On 11/28/2021, my vehicle suddenly showing five warnings 1, front camera sensor malfunction, 2, smart brake system malfunction, 3, forward smart city brake support malfunction, 4, HBC/LAS system malfunction, and 5, SCBC malfunction. I have no idea which part was go wrong, but this is not the first time my vehicle shows the same warning. Back to 12/20/2019, my vehicle has a same warning showed, I bring my vehicle to dealer to check but after they check, they told me nothing wrong. After two year the same problem come out again, I am very concern about the safety of my vehicle. The first time having a issue was my vehicle just a year old, and today the same issue come out again. Please help me to look up my vehicle is it any part has to recall and need to fix it. Thank you
While driving through town the braking system malfunctioned and the car came to a stop in the middle of the road with messages on dash saying the smart city braking support was malfunctioning as well as brake assist. Engine light came on as well as traction control light right after the car coming to a sudden hard braking stop. Drove straight to shop to check engine code which was p0882. I am so afraid of this happening on the highway with my daughter in the car. There is a recall for this system but my car isn't under the recall so I'm sure there are others that are having the issue but aren't covered under the recall either.
Sometimes, the breaks will not go all the way down to the floor and act like theyre not working. it's very odd and only does it once in a while. i have constant issues with the technology in the car. it changes my music, the buttons get stuck and my it acts up. my aunt has the same model and is running into the same issues. i never received a letter in the mail about the last recall and have had issues where it doesnt seem like my engine is getting the power it once did. this was early on after i got the car. my gas mileage has significally decreased even after oil changes.
Parking brake system malfunction. Flashing brake light and the parking exclamation point light on. When I try to release the emergency parking brake it continues to light up on the dashboard as well as yellow flashing light on the physical brake similar problem with 2016 model. Seen multiple people with similar problem but no solution Restarting the car multiple times makes the light go away eventually
Car has 38000 miles and the caliber needed replaced yesterday. Brakes started grinding a day before that slightly in the morning by the time I got off work and drove home it was so loud I was terrified to break at all. Mechanic said he's not seen calipers seize up like that in a newer model car.
