The engine has a massive oil leak that seems to be more common than Mazda will admit. The safety-related issue is the oil pours out like pancake syrup which can be bad for other drivers, the environment and cause road asphalt to break down at a rapid pace. I also don't have a warranty. When I consulted Mazda all they wanted to do is charge me $7,000 for a new engine from all the research I found on the internet. This is a problem that is affecting many people because when you only have one vehicle and have no way to make money. Most people will just keep adding oil to keep it going. Many customers are left with a car payment with no way out and a car they can't really drive other than short distances. Something needs to be done to hold them accountable for this common problem. I don't know anyone that can afford a $ 40,000-yard brick. If we can hold big pharma accountable why not vehicle manufactories.

There is no recall on this which is a huge safety issue. This has happened to me on highway several times and Mazda will not do anything about it. Very dangerous when you are going 65 on a highway! TSB Number 01-007/19- misfire P0304- of 4th cylinder. Recommendation to replace main silencer due to condensation accumulation in the exhaust baffle. Please search the TSB and misfire code I provided to learn more about it. If you are out of warranty. You are out of luck with Mazda. I will take upon myself to educate others where Mazda could careless to correct this or let the public now.

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.

Engine turned off while making a k turn. This is the same issue I experienced in 2019. Mazda issued a recall for software malfunction shortly thereafter and my car was serviced as part of this recall (NHTSA campaign number: 19V497). But now the exact issue happened again last week.

Will not accelerate at times no matter how far you press down on gas pedal and will stall right after. I will pull over shut off vehicle and restart. This sometimes corrects the problem right away. Other times it lasts longer. System malfunction light randomly comes on.

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.

- Plano , TX, USA

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.

When taking vehicle in for recommended 45K mile service, dealer discovered warped head cylinder and leaking oil. No check engine light warning ever came on! no warning. Mazda is replacing engine parts under vehicle warranty

I purchased this VIN less than 24 hours ago, I was told it was certified by the dealership. In looking up the VIN on www.NHTSA.gov this am, it says the recall #3719F was not fixed; the dealership just sent me a screen shot from Mazda North America operations warranty vehicle inquiry report, and it shows the repair done. Who do I believe? the vehicle is at my home on the drive way, stationary. I'm asking the dealership to pick the car up, and refund my $100 dollars. They want $400 more when I get paid 2/25.

I was driving on the highway and it was raining. I lost control of the vehicle, the steering wheel was spinning uncontrollably. I was advised I most likely hydroplaned. The vehicle finally slowed down and backed into a guardrail. Only the rim of the driver side back tire was damaged. The impact felt like the impact felt when hitting a curb too hard. This did not happen on the side of the road with a shoulder, so after the tire hit the guardrail, I moved to the car to the other side of the road to be on the shoulder. Once I arrived at the other side of the road, the airbags deployed and the brake assist light came on and the police were automatically called. The car was towed and the collision shop cannot explain why the airbags deployed. I'm terrified that the airbags can deploy at any time for any reason. I am also terrified that they will not deploy when they are supposed to since they deployed at least 10-15 seconds after the impact with the guardrail occurred.

The engine in my Mazda Cx-5 was required to be replaced recently due to a known issue in the car that causes the rear head to leak. My car has less than 12,000 miles on it so the engine should not have this issue. My dealer explained to me this is a known issue by Mazda and he had seen 5-10 other cars just at his dealer. We noticed this issue when my son was driving the car and we saw fluid pouring out of the bottom. We had him stop the car immediately and not drive. I tried numerous times to get Mazda to engage to provide a better warranty given it is a new car should not have a blown engine with only 12,000 miles and it is a known issue but they refused to provide any support. I asked about why no recall and they just stated there is no recall for this issue, although the dealer highlighted Mazda is aware of a flaw in the car that caused the rear head to leak. I would like to seek some action with Mazda to make them deal with this very concerning issue
