2018 Mazda CX-5

While driving, my car has stopped two times. first time I crashed on the side of road causing all of my tires and rim busted and had to replace all of them. I had no idea what was going on. second time I was taking kids to school where can just stopped in the middle of road and restarted. Recently it was smelling so I took it to dealer where they said its one of the cylinder and its not safe to drive so they replaced it as its under warranty. While my car is been with Mazda dealer I have been using their loaner car. but then received this letter of Safety recall on similar issue i had in the past and i have been trying to contact Mazda but no success. no email, chat or phone call response. I do not feel safe to drive this car which i bought in 2018, its been having lot of engine related issues. and i do not feel safe to drive this car with my kids in it. I have requested Dealer to let me keep the loner car until they fix safety recall issue. and i am trying to contact Mazda but no response please help.

Massive oil leak onto exhaust manifold, dealership checked and found oil leaking from right rear area of cylinder head. "Per SA/031/21 should replace cylinder head and all gaskets and hardware". My safety and the safety of others was put at risk because if my car had no oil in it, which it was close to, the engine could have seized and caused an accident. The fumes of burning oil made me severely ill as well. The problem was confirmed by the Mazda dealership and has been inspected as well. The only reason I knew something was wrong was because the oil light came on and I contacted the dealership and they said it was a sensor issue and I did not believe that they were correct so I brought it in and they looked at it and said it was a massive oil leak and then told me that the cylinder head assembly needed to be replaced and it was a rare occurance but it had happened due to a casting issue.

This is more of a general notice to fellow Mazda CX-5 drivers with the issue described below: Our car is a 2018 CX-5 with 25K miles. The check engine light came on upon entering the highway at the beginning of the day. Subsequently, stopping by an AutoZone to diagnose it revealed a malfunctioning thermostat. Only then did I realize the car took a long time to reach the operating temperature (for the blue indicator light to go away), and engine temperature would generally stay around 165 and hit 210 only after a very long time of driving, while idling or in traffic. However, our internal heater performance never had any issues while being kept at 75 and blowing mild to moderately. Upon taking the car to our Mazda dealership and requesting a diagnostic service, did we learn it was a malfunctioning coolant control valve that there is a technical service bulletin (# 01-011/21) for such a thing, and covered under our CPO powertrain warranty for replacement.

Approximately 9:15am 5/16/21 I was driving on the road when my engine stalled and went out. Was stuck in the middle of the road for a couple of minutes while I tried to restart the car. My vehicle was recalled for this very purpose but 13 days prior I went into the dealership to fix the issue and get a software update. After said update I experienced the recall issue on my vehicle.

SITUATION: DRIVING UPHILL ON HWY 120 ON NEW PRIEST ROAD, BIG OAK FLAT, CA, TWO LANE MOUNTAIN ROAD. SLOW CAR IN FRONT OF ME AND A DELIVERY TRUCK TAILGATING. SLOW CAR EVENTUALLY MOVES ASIDE IN A TURNOUT AND I ACCELERATE TO OPEN UP SPACE BETWEEN MYSELF AND WHAT I THOUGHT WOULD BE THE TRUCK BUT SOMEHOW THE SLOW CAR RETURNED TO THE DRIVING LANE AHEAD OF THE TRUCK. I CONTINUE TO ACCELERATE TO ATTEMPT TO OPEN UP SPACE BETWEEN MYSELF AND THE CAR BEHIND ME WHEN I LOST POWER, THE CAR BEHIND ME MOVES TO THE OPPOSING TRAFFIC LANE TO AVOID REAR ENDING MY CAR THAT IS RUNNING IN DEGRADED MODE (ACCELERATOR HAS NO EFFECT, BASICALLY MOVING ON IDLE POWER) AND NARROWLY MISSES AN ONCOMING CAR AS I MOVE TOWARDS THE RIGHT EDGE OF THE RIGHT LANE. TRUCK BEHIND ME HAS TO BRAKE HARD TO AVOID REAR ENDING ME. THERE WAS NO SHOULDER TO PULL OVER TO AT THAT LOCATION IMMEDIATE LOCATION. I PULL OVER A FEW HUNDRED YARDS FURTHER AT A SAFE LOCATION. GRADE WAS PERHAPS 4% TO 6%. WEATHER: HOT 90 DEGREES SPEED: ACCELERATING FROM 35 TO 50 MPH (GUESS) DIAGNOSTIC LIGHTS: SMART CITY BRAKING SYSTEM FAILURE WARNING, PLUS A LOT OF OTHER WARNING LIGHTS LIT INCLUDING CHECK ENGINE LIGHT. AFTERMATH: I PULLED SAFELY OVER, STOPPED THE ENGINE, WAITED A WHILE AND RESTARTED THE ENGINE AND THE CAR RETURNED TO IT'S NORMAL DRIVING BEHAVIOR AND COMPLETED MY TRIP. OTHER INFORMATION: THIS IS THE 3RD OCCURRENCE OF THIS BEHAVIOR. EACH TIME I HAVE HAD MAZDA LOOK AT THE PROBLEM. 1ST OCCURRENCE THEY REPLACED THE CYLINDER COIL, 2ND OCCURRENCE THEY REPLACED A SPARK PLUG FOR MISFIRE. 3RD OCCURRENCE, TO BE DETERMINED.
