MAZDA Complaints

The contact owns a 2019 Mazda CX-5. The contact stated that while operating the vehicle, the message that the engine oil level was low was displayed. The contact stated that oil was added to the engine; however, the next day the message reoccurred. The contact stated that later while the vehicle was parked, the contact discovered an oil leak underneath the vehicle. The vehicle was driven to the local mechanic who confirmed oil leaking from the engine, but the cause of the oil leak was not yet determined. The local dealer was contacted, and a service appointment was scheduled. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer was not contacted about the failure. The failure mileage was 96,600.

Starting [XXX], through [XXX], we began receiving multiple "Critical Vehicle Malfunction" alerts (46 alert messages)via the Mazda app, including "Parking Brake Malfunction" and "Electric Parking Brake Malfunction." During this time, the vehicle experienced delayed starts and eventually required a jump-start. We brought it to the dealership multiple times to show the messages, before our 3-year/36,000-mile B2B warranty expired, but the issues were dismissed until the battery was finally replaced. At just over 36,000 miles (currently 39,646), a new issue emerged a “thud” sound from the steering wheel. The dealer diagnosed it as a failed u-joint shaft, which was deemed non-serviceable and not covered under warranty. I inquired about potential causes or prevention—no clear answer was known. I found relevant NHTSA TSBs (06-001/20 & 06-001/24) related to steering issues and escalated to Mazda USA. Mazda agreed to cover 50% as a goodwill gesture, leaving me to pay about $500. Two weeks later, the part arrived and was installed—but it did not fix the issue. The dealership now says it’s a failed bearing within the Electric Power Steering (EPS) unit, which requires complete replacement at a cost of over $2,000. Only one part is available in the U.S., with another two-week wait. The original (misdiagnosed) part was already sent back to Mazda. My out-of-pocket cost is now $1,151 and rising. Given the early warning alerts, misdiagnoses, and the fact that EPS controls several safety-critical functions (steering, cruise, lane assist, etc.), I believe this is a fundamental system failure that should be fully covered under warranty or as a safety-related goodwill repair. I respectfully request that Mazda assume full financial responsibility for the replacement and any related work. Thank you for your consideration.

The engine light constantly appears along with the "Schedule Maintenance Soon" light. Taken to dealership many times within my 3 month warranty and no definite reason was given.The vehicle rides very bumpy though sway bar was inspected and supposedly repaired by dealership during my 3 month warranty.

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.

My brakes went out with no warning, or light on dashboard. I had the master cylinder changed and all brakes bled. The brakes went out 2months later,so changed the master cylinder again. 1 month after the brakes went out again. So I called Mazda service department and the gentleman told me to try and change the brake booster. So I changed the brake booster and master cylinder. 6 days later my brakes went out again, mazda told me they having issues with older model mazda tribute brakes going out. I have to get a rebuilt master cylinder for my car. My brakes have gone out on me 4 times and I almost wrecked each time. This is ridiculous I am scared to drive my car now and I have to keep paying a mechanic to do the repair and it's not working.

One of the cylinder heads on the back portion of the motor cracked, leaking oil down into the engine compartment. I didn't realize this was an issue until I got a warning about low oil. I went and got an oil change and within 2 days I had the low oil warning again. I had no other warnings that this was going on. This creates a potentially dangerous situation with people leaking oil onto roads and highways unknowingly. It was inspected by Mazda and confirmed to be the issue. There is currently a TSB from Mazda about it. But my car wasn't included in it. TSB 01-002/23

Bought used with 47k miles. Two weeks later, took it to my mechanic for an inspection, they found a massive oil leak on the back of the motor. Took it back to the dealership and they diagnosed it as a cracked cylinder head, for which there is a known TSB and warranty extension. Unfortunately, the warranty extension only covers a coolant leak from the cracked cylinder head, not an oil leak. Thankfully, the dealership took care of me but had they not, I was looking at a $7k+ repair on a car I had owned for 2 weeks. In the TSB, Mazda acknowledges that there were both design and manufacturing flaws for the affected model years. In acknowledging the issue, they should have issued a recall for affected vehicles, not a simple warranty extension
