2018 MAZDA MAZDA6 Power Train Problems

I recently discovered a significant oil leak near the exhaust manifold of my 2018 Mazda 6 (2.5L NA), which has resulted in visible smoke and a burning oil odor. Upon taking the vehicle to the nearest Mazda dealership for a diagnosis, the service department informed me that the vehicle has suffered a cracked cylinder head. An active oil drip is visible behind the engine near the exhaust manifold immediately upon starting the car; consequently, the engine is leaking oil directly onto the exhaust components. This condition not only renders the vehicle inoperable but also presents a significant safety and fire hazard. At the time of this writing, my vehicle has only 46,996 miles and has been meticulously maintained. This mileage is well under the 60,000-mile powertrain threshold and represents a premature failure of a major internal engine component. There are numerous reports on Mazda owner forums describing this identical issue...

Was driving then car suddenly shut down and all panel lights turned on. The car would not start after an hour it started but was Perkins when driving. Mechanics were unable to diagnose the issue.

Noticed slight coolant leak, took car to mechanic, he stated cylinder head was cracked, & causing coolant to spray everywhere. Towed car to dealer. Was given repair estimate of over $11,000, for a new engine. I see a safety bulletin online for my year make & model car. This overheating can apparently cause an engine fire. So far, Mazda seems to be showing negligence & not properly addressing the issue for owners.

The contact owns a 2018 Mazda Mazda6. The contact stated that he had experienced a transmission surged on five separate occasions since owning the vehicle. There were no warning lights illuminated. The contact had taken the vehicle to the dealer after each failure and various unknown repairs and software updates were performed on the vehicle. However, the failure persisted after each visit. The manufacturer was notified of the failure and a case was opened. The vehicle was not repaired. The failure mileage was approximately 10,000.

I took my car in for scheduled maintenance and the technicians at the Mazda dealer found out the tensioner and belt needed to be replaced, when the car is less than 36k in miles. Vehicles being repaired under warranty but a tensioner should not be going out this early in the lifespan of a 2 year old car. I have found a lot of people are complaining for the same issue. This can cause the cars to not run as there’s no notice ahead of time that the belt and tensioner are bad. I do have paper work stating tensioner problems. Vehicles should be recalled due to poor manufacturing and parts making it unsafe on the road.

THE FRONT AND REAR SUSPENSION POPS, CLUNKS, THE VEHICLE SHAKES, VIBRATION ALSO HAPPENS, IT ALSO CAUSING TIRES TO BE REPLACED FASTER THAN NORMAL THEY GO BOLD IN THE CENTER ITS CAUSING NOW THE AXLES TO SHAKE AT NIGHT TIME YOU CAN SEE THE REFLECTION FROM HEADLIGHTS BOUNCING, THEY HAVE TSB'S ON THIS SUSPENSION ISSUE HOWEVER NOT FOR 2018 ONLY 14-16 MAZDA 6S I BELIEVE AND SUPPOSEDLY THE ISSUE WAS CORRECTED WELL THEY LIED BECAUSE MINE IS A 18 AND IT IS A DISASTER, MY TRANSMISSION IS NOW SHIFTING VERY HARD FROM 1ST TO SECOND GEAR, TURN WHEEL IT MAKES A LOUD CLUNK SOUND OR POPPING SOUND, GO OVER A DIP IN ROAD DOES THE SAME THING, YOU GO OVER A BUMP THE VEHICLE FEELS SOGGY, IT LIKE DRIBBLES, IT CAUSES THE VEHICLE TO SWAY.. IT'S HORRIBLE, ALSO THE BRAKES WAS SHAKING AT 15K MILES, FOUND OUT IT'S TSBS ON THIS...

I GOT THIS CAR IN MAY OF 2019 SO THE CAR IS STILL NEW AND EVER SINCE I PURCHASED THE VEHICLE I'VE BEEN HAVING ISSUES WITH IT FIRST WERE THE CALIPERS STICKING AND MAZDA GAVE ME A HARD TIME TO REPAIR THE ISSUE AFTER THE FACT KNOWING THAT IT WAS A MANUFACTURING ISSSUE AND STILL TRIED TO CHARGE ME I TOOK MY VEHICLE THERE MORE THEN 15 TIMES JUST TO DEAL THINGS GOING BAD IN MY CAR. MY CAR STALLS ON ME OUT OF NO WHERE WHEN I'M DRIVING WHICH IS DANGEROUS AND CAN CAUSE ME TO CRASH ALSO MY CAR BRAKES WHEN THERE ISN'T ANYTHING IN FRONT OF IT ALL MY MALFUNCTIONING INDICATORS ARE ON AND I HAVE VIDEO PROOF AND SHOWED IT TO MY SERVICE ADVISOR AND SERVICE MANAGER AND THEY STILL DIDN'T REPAIR MY CAR AND TOLD ME THAT I HAVE TO PAY OR GO SOMEWHERE ELSE...
