MAZDA Complaints

There is a bearing in the crankshaft that looks like it’s not up to spec. No warning lights came on, car suddenly lost power on the highway. Fortunately no one was injured though it was a very scary situation. Mechanic took a look inside the engine and said a main bearing stud broke off and busted a hole through the short block. He said I’m lucky the engine didn’t turn into a grenade. Upon looking up the failure many other people have had the same issue with this engine. The exact same failure on the exact same bolt. Here are some links to some posts: [XXX] [XXX] [XXX] [XXX] Clearly I’m not the only one with this issue, and there are more examples of the same problem that you can find online through out different Mazda models that use the same engine. I can definitely have the vehicle inspected if needed, my mechanic took video of the damage as well. I could only imagine if this happened while there was more traffic on the road, it’s not safe. And the fact I can find more examples means there are probably more that never posted or reported the issue. the vehicle has less than 100k miles which a lot of the examples have the same issue at less than 100k INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My engine suddenly started smelling like burning oil. I was due for an oil change and needed it immediately so I went to a quick oil change shop. They told me oil was sprayed all over the engine and I should take it to the dealer. It's been at Napleton Auto Park in Urbana, Illinois for a week and they finally diagnosed a cracked cylinder head. They said it could take up to 2 months to repair and they're checking to see if it's covered by my warranty.

The contact owns a 2018 Mazda CX-9. The contact stated that while the vehicle was parked, he observed condensation under the vehicle. The vehicle was towed to an independent mechanic where it was diagnosed that the engine needed to be replaced. The vehicle was repaired but the failure persisted. The contact stated that while the vehicle was parked, he observed condensation under the engine compartment and on the top of the engine. The vehicle was taken to an independent mechanic where it was diagnosed that there was a crack in the cylinder head and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 68,000.

We were driving in a snowstorm during the daytime on a 2-lane highway with directional passing lanes (where it opens and closes, not crossing into oncoming lane to pass) from CO to UT. While passing a semi truck, with traffic in the oncoming lane, and behind us, the auto-braking activated. There were no vehicles in front of us. The alert went off, and the car rapidly slowed from 70 to 35, and applying the gas did not resolve the issue. This almost caused a rear end collision by other cars also trying to pass the semi. We think it was either caused by slush thrown up by the passed truck tires, or a slight curve in the road that made the computer think that someone was in front of us. Whatever it was, it was very dangerous to have the brakes slammed on on a snow road with vehicles all around us.

For a few weeks in November 2023, I had my dash alarm/notify me when I would turn on my car and it would state "Airbag System Malfunction" then disappear. Potential risk with this issue is that the airbag may deploy randomly or not deploy at all if collision happens. This is extremely scary as I have a child and I commute daily for work. I have turned my car into the dealer since 11/29/23 and currently have a loaner. No update so far from the dealer.

These are two major problem i want to highlight, which need immediate attention One of them is related to steering wheel, which is a major safety concern for this vehicle to be on road. 1) Major safety concern- steering wheel Steering wheel is catchy when you are driving vehicle on high speed, which make this vehicle so difficult to control/ maneuver and struggling to keep this in a lane Steering wheel catchy means- it becomes hard when you steer and then skid before finally engaged. This makes driver nervous and can lead to an accident due to wavy drive 2) Engine malfunction light alert in instrumental cluster get on. This give you no choice whether to continue with vehicle. On Nov 23rd 2023, i was travelling with my family on [XXX] from ann arbor Michigan to columbus ohio and get stuck in highway due to this suddenly popped up Currently, vehicle is with germain mazda columbus and getting diagnosed. However, they confirmed some steering wheel motor problem and they are engaged with mazda corporate. But at the time of this reporting, they have this part backlog of 5 month and will be available by April 2024 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2019 Mazda CX-5 cylinder head cracked at only 60,000 miles. I noticed my breaks were smoking and stopped driving. I then noticed oil leaking from my engine which had blown into my breaks, causing the smoke. There was no check engine indicator on my dashboard, nor did it indicate that my engine had overheated. There was no indication that there was any issues with the vehicle until i noticed the smoke coming from my brakes. I towed the vehicle to the Captial Mazda Dealership in San Jose, CA. Per Mazda Dealership Repair Estimate: "cylinder head cracked by cylinders 2 and 3". When i asked the dealership service center why this happened, their only response was it was a engine failure and that "over time the cylinder can become warped and crack" and while it that doesn't happen often "it can happen" I asked if there was anything I did that caused this, their only response was "i can check with the technician again". Apparently I did not purchase the "extended warranty" so while the repairs are no fault of my own, I have to pay the $6,000 repair cost.

I am reporting a safety problem with the adaptive cruise control feature of my 2023 Mazda CX-90. The adaptive cruise control system does not detect the lanes correctly and applies the brakes unnecessarily, even when there are no cars in front of me. This happens especially on curves and when there are trucks on other lanes. This is very dangerous and I have been close to be rear-ended several times. I do not feel safe driving this car with this feature on. I haven't contacted my dealer, but it seems to be a well known issue for many owners.

Fuel smell after a fill-up, fuel pump is cracked/deformed EXACTLY as described in Mazda bulletin 5321K (THIS BULLETIN EXCLUDES THIS MODEL). Strong fuel smell in the cabin, liquid fuel leaking from the top of the tank.

My air bag light warning light is constantly blinking and I took it to the dealer ship. I informed the service guy this could be a malfunction due to a recall. He only asked me to pay for an diagnostic for $175.00. I think based on a history dated from 2004-2018 regarding Air bags recalls this is a recall. I contacted Mazda 1-800-222-5500 Option 11/28/2023 @ 10:00 am I reported this to Mazda Vehicle Claim#[XXX] and they are stating it is no recall for that vehicle. I think this is a safety risk for me and Mazda needs to address this at no charge based on the history of several vehicles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
