On 12/23 I was driving on the highway approaching exit 43 A-B on I-95 N and the engine oil light came on, I started monitoring the temperature of the car and it was holding steady, neither was it dropping nor was it overheating. I continued driving for a minute more, I am half mile away from home at this point and I smelled burning oil. I pulled the car over and opened up the hood, I turned on the flashlight on my phone and I could see oil on the engine floor. I called up Mazda dealership near me and they were closed for the holidays so I left voicemails. After a couple of days of no answers, I was able to get through to someone and they said they'll take the car in however they can't guarantee if they will be able to even look at it until after the holiday, I speak to the service manager and mention that I have an upcoming trip out of state for Christmas, they said they did not have any loaner cars available either. I got my car towed to the dealership anyways. Next day I get a phonecall from them stating that the oil pump and pressure was fine and they suspect it was the engine head that was causing the leak and that it would cost me 6000$ to fix it. Along with that I need to get my belt tensioner fixed which would be around 680$. The car's estimated value is about 12000$ and I am being asked to pay more than half its value after owning it for 4 years to fix something that was caused by wear and tear. I also did a little digging and I've found that my car falls under ones that have been identified by Mazda to probably have a defective engine head. I am attaching the reports that I have discovered in my research with this submission. I am imploring for assistance in this matter as I cannot afford this expense and I would not like to part ways with something that has been reliable for the last 4+ years.

Hello, I am writing to you for a possible failure post update to the software as specified in Recall 19V-497 dated 09/06/2022 found on the manufacturer's recall website (https://www.mazdarecallinfo.com/). The status is marked as CLOSED. However, I faced the exact problem yesterday as described in the Safety Risk section of the recall details on their website (Summary section on NHTSA website). Below is my best attempt to describe my event: Event: I made a stop at a red light. As it turned green, I accelerated and the engine shut off/stalled. I pushed the engine stop button, switched gear to "P", and the car won't start at all. I was also not able to press the brake or accelerator. I was not able to move the gearstick. Safety risk: My car stalled in the middle of the road. It was a busy junction. If this occurred on a highway, it is possible this may lead to serious injuries or death. After-events: I got the car towed to the dealership where I was told by the service crew that the car worked fine. I was sent a video of multipoint inspection with recommended additional services, a business that I understand. However, they were not able to identify the cause of the engine stall. I decided to check recall information and found this recall (19V-497) with status as CLOSED. But this is the exact problem I faced yesterday. Therefore, either/some/all of the below cases are possible: 1. The status is marked incorrectly as CLOSED 2. The date of recall on the website is misleading; this recall was placed 06/27/2019. 3. My service did not actually service the recall (I service my car every 5000 miles) 4. The recall failed to resolve the engine stall issue. 5. Issue may not be related to failure of this recall remediation; meaning, service did not perform a root-cause inspection of the problem itself. This message is intended to keep you informed in case point (4) holds true.

My wife was pulling into a parking place today with her foot on the brake when the car suddenly accelerated, causing it to jump a curb and come to a stop over two large shrubs, which saved her from entering a busy highway and colliding with another car. This caused damage to the front end of the car and wheel wells. She told me she absolutely did not have her foot on the accelerator at the time. The cruse control was off and the driver's side floor mat was not out of position. She was not injured and the air bags did not go off. We have not yet taken this vehicle in for inspection of this defect. It is in the repair shop right now for body work. Our insurance company has been notified. My wife did not report any warning lights. The vehicle is available for inspection. Prior to this episode, I have noticed that at low speeds, the car tends to "surge" with slight pressure on the accelerator but we did not report that to the dealer.

2018 Mazda CX5 with 62000 has an oil leak coming from what the Mazda dealership in Barre VT say it is the cylinder head and gasket have gone faulty for a repair price of $4,191 and that this is a known issue. I had no lights letting me know of an oil leak, the only way I knew it was leaking was because I smelled burnt oil and then looked under the car to see the drops from the leak. My complaint is if Mazda Corporation knows its a known issue and know it can cause a fire why does it not issue a recall. An engine should not be having faulty cylinder and gaskets at only 62,000 miles.

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.
