Had the sudden onset of strong exhaust fumes in the cabin as others have described - especially when idling at a light. Returned to dealer after having it up on a rack to find oil dripping everywhere (shield underneath prevents from seeing drops when parked) - got word today it is indeed the cylinder head assembly. How is oil running on hot exhaust not a fire concern? I had to roll my windows down for fresh air in zero degree weather the fumes were so strong inside the vehicle. On top of that the P0126 (thermostat stuck open) diagnostic code is back for the second year in a row after having the -??fix-?? installed under warranty last year.

Car will whine and jerk when accelerating. Car suddenly stopped engaging in gear after it was warm. Dealer states it has internal transmission malfunction at 64k miles. Prior to the car breaking down the vehicle was taken to the dealer for a diagnostic on 12/27/23 and concerns with the whining and jerking when driving were expressed. Dealer reports that the transmission was -??operating as designed-??.

The 2019 CX-5 has approximately 31086 miles. It was discovered that the cylinder head is cracked and causing the car to leak oil.

My 2019 Mazda CX-5 cylinder head cracked at only 60,000 miles. I noticed my breaks were smoking and stopped driving. I then noticed oil leaking from my engine which had blown into my breaks, causing the smoke. There was no check engine indicator on my dashboard, nor did it indicate that my engine had overheated. There was no indication that there was any issues with the vehicle until i noticed the smoke coming from my brakes. I towed the vehicle to the Captial Mazda Dealership in San Jose, CA. Per Mazda Dealership Repair Estimate: "cylinder head cracked by cylinders 2 and 3". When i asked the dealership service center why this happened, their only response was it was a engine failure and that "over time the cylinder can become warped and crack" and while it that doesn't happen often "it can happen" I asked if there was anything I did that caused this, their only response was "i can check with the technician again". Apparently I did not purchase the "extended warranty" so while the repairs are no fault of my own, I have to pay the $6,000 repair cost.

I drove my wife to work and noticed that the car was stuttering and had weak acceleration. I parked in my garage and a couple of hours later returned to see a massive oil leak on my driveway, I had to tow the car to the nearest dealership where a cracked cylinder was diagnosed. There was also a terrible burning smell. If the massive leak happened on an acceleration ramp or on the highway there could have been an accident.

After purchasing this vehicle I started noticing that as I accelerated from a stop the transmission would shift hard into 1st gear and 3rd gear. This is also occurring during deceleration as if the car brakes I'm stages due to the downshifting hard. The dealership has refused to look into the issue. They have refused to add the notes to my vehicle records in effort to avoid accountability.

Driving on highway, cruise control ser to 82, no cars in front. The car suddenly jolted twice, engine light and battery light comes, lost of power. Pulled over to shoulder in the middle of nowhere in Nevada. Tried to start the car, engine won't turn on, starter just kept cycling. Veh temp was just below 210 with a 1/4 tank of gas. Called dealership and service person asked is to use key to turn on car, no change and provided no other solution other than to take to dealership with the closest one being over 300 miles away. We decided to unhook and rebook the positive side of battery. Car restarted and currently driving it home as I write this complaint. 600 miles overdue for maintenance (by date due on July 26, 2021) and was scheduled upon return from trip which at the time should be approx 1000 miles over due.

Brought it in Nov 2020 regarding smells and engine issues as well as alignment. Neither were taken care of. Then March 2021, engine was leaking fluid and smoking, and the engine needed to be replaced at 20K. Did not provide a rental until later that week. After a month, I got my car back. After leaving the engine continued to smoke, brought it back. Gave no rental. Dealer said it was left over fluid from when they replaced it. Car is still having issues with the engine and smells. Under shield fell off and needed to be replaced twice.tire pressure was going off and brought it in twice for them to say they cant find where the slow leak is or why so they wouldn't fix it even though I have the Mazda insurance for tires.

In July 2019 (approximately 2 months after delivery) my 2019 Mazda Cx-5 began to drive roughly at slow speeds- specifically speeds 15 mph or below. The vehicle would not coast (even downhill) and would seem to slip out of gear (this vehicle has an automatic transmission). More specifically, the vehicle would buck and lurch on it's own without engaging the accelerator or brake. This was happening going uphill, downhill and on flat grade. I brought the vehicle to the dealer and at their request took an employee for a drive so they could feel it. The employee did feel it, told the service manager, who then told me that, "they are supposed to drive like that." He said he drove around another vehicle on the lot that is the same model and year, and that it performed the same. Please note that this is not the same person who was in the car to experience how my car was driving. I personally know two other people who have the same exact year and model Cx-5. I shared my experience with both owners- they both told me that their cars do not perform in that way. Additionally, I drove one of those vehicle and that one did not perform in the same way that mine does. I am concerned that this issue is being brushed off. There is no way that Mazda would purposely design a car so that it jerks, lurches, and bucks at slow speeds. I have read reviews on online message boards where others do complain of similar experiences, which is even more concerning. This poses a safety issue for the driver, passengers, and others on the road who may be driving nearby. I have an appointment and will be taking the car back this coming Monday to try and further address this issue, but felt it necessary to file here in the case that further action needs to be taken at a larger scale since it appears as if others, though not all, 2019 Mazda Cx-5 owners are experiencing the same.

On Monday, November 25, 2019, as I was approaching my home, I activated my garage door opener and the garage door opened as I pulled into my driveway. I stopped the car, a 2019 Mazda Cx-5, in the driveway, placed it in park, got out of my vehicle and entered the garage. While in the garage for approximately 2-3 minutes, I turned around to see my 2019 Mazda Cx-5 accelerating toward me. The car rolled until it hit the washing machine and dryer. I managed to avoid getting pinned but not before the car ran over my foot. I managed to squeeze past and enter the vehicle placing my foot on the brake and putting the car back in park.
