Engine · reported Nov 3, 2026

Cracker cylinder head at only 68,000 miles on it. No warning came on, only reason we knew it started was oil leaking really bad

Engine · reported Oct 29, 2026

I'm having an issue getting the recall serviced. Apparently, because the car's VIN number traces it's origin to [XXX], Mazda USA is unable to confirm the recall notice and the local dealership (Norcross Mazda) couldn't confirm it either when I tried to book an appointment. Mazda USA and the local Mazda sites both show the open recall on the customer end, but not on the corporate end for some reason.

Tether, Lower Anchor (On Car Seat or Vehicle) · reported Aug 29, 2026

Have had 3 seats replaced under warranty by Graco and was told to make a report with you. The rigid latch anchors on two have been faulty after 2 months. The second one got stuck in the installed base and pulling the release button did nothing. The rigid latch on the first got stuck in the open position. The second they would move independently of each other and not lock in. The third is starting to have the same issue with getting stuck in the base. These have all happened within two months of normal use.

Engine · reported Aug 7, 2026

The car only has 70k miles on it. The engine started smoking under the hood. Immediately stopped to look. There was oil leaking but I could not see from where. I took it across the street to the Toyota dealership and had them look at it. They explained to me that there was a crack in the cylinder head and oil was leaking everywhere. Potentially causing a fire or even an explosion. The old was leaking all over the exhaust manifold and engine. I had my 2 toddlers in the car not long before this happened. This is extremely unacceptable. Currently Mazda is saying it will be 7200 to replace the…

Vehicle Speed Control · reported Jul 29, 2026

Got error message that said "Forward Smart City Brake Support Malfunction" slso fot "smart brake malfunction" while driving. The ac stopped, the car speedometer kept going from 50 to zero. The car died and couldn't open doors, windows. Lost steering while driving. We were able to get off road and restart and fine for 2 weeks. While at still light tonight, the car turned off. Windows were up, couldn't open door, emergency blinkers would not come on. This is very dangerous.
