Engine is either burning or leaking oil. The low oil light flashed after a 2hr highway trip (traveling to my parent's house for Christmas with my wife), low oil was confirmed the following day via dipstick. Oil was changed at the dealership about 4 months ago, mileage is under 24k miles. Looks to be related to this service bulletin, which still does not appear to have a fix or recall associated with it.

Check engine oil light came on after only 2K miles from last oil change. Upon inspection there was practically no oil in my engine!!! I see there is an ongoing issue since 10/21 with 2021 Mazda CX-5 turbo engines. Despite Mazda’s awareness of the problem, they have yet to issue a recall to fix this issue!!!
ON Nov 4th my Mazda CX5 alerted me to low engine oil level by illuminating dashboard symbol and app notification. I attached a file containing an explanation of the issue, emails directed to Mazda corporation and Napelton Mazda in Naperville IL. I also attached screenshots of the in app notification and the Mazda TSB which I had to find on my own because Mazda coporate and both the selling/servicing dealer would not acknowledge the oil burning issue.

Bought the car brand new in May 2021, did a first oil change at around 4K miles due to the fact the car uses conventional 5w-30 oil and not synthetic oil. At around 7k miles the low oil engine light came on. Checked the dipstick and it was low. Added a quart of oil to hold me over until the next available appointment. Dealer could not find any leaks, they completed a oil change again. I went in again at 11K for another oil change. Had no problems. A few days ago at 14K low engine light came on, this time I turned the car off. Let it sit over night. Made an appointment with the dealer for the next day. Turned the car on the next morning, light went away. Both times I got a notification from Mazda connect services alerting me of these problems. (Please see attached) I brought the car in on 1
When I reached 7000 miles on my car the low oil light came one. I immediately drove it to the dealership - ending a vacation early as I thought something was seriously wrong with the car. I got to dealership and they blamed me for getting an oil change at a competitor and not putting in enough oil. They then changed the oil and again at 12000 the low oil light came on. There seems to be an oil consumption issue that Mazda is NOT admitting to or fixing. Every time I drive more than 4500 miles the car is 1/2 a quart low and it warns me. Now the dealership wants me to spend HUNDREDS of dollars on a vehicle in warranty for oil consumption testing....though there is no leak and no soot in the tail pipe.
Low oil level between oil change cycles with over 1,000 miles remaining before oil change is required. This has happened between both oil changes so far and I have to add oil myself to ensure oil level isn’t low. The oil consumption seems extremely high and is concerning that at only 12,000 miles I’ve had this problem happen twice.
Engine developed a major oil leak at 70,000 miles, with multiple seals leaking. This appears to be a known defect with these vehicles and owners should not be bearing the cost for repairs.

The car has a key fob which is supposed to automatically lock the car when you walk away (and unlock when you press a button on the door handle when the fob is in close proximity). My car sometimes does not lock when I walk away. They encourage relying on this method, and so sometimes I return to my car, and it is unlocked. I consider this a safety issue both from a personal safety standpoint and from a car theft/ interior item theft standpoint. I have tried discussing this with the dealership repair department, but they mansplain to me that you have to walk FAR away for the lock to activate (which is actually directly contrary to the owner's manual for this model, as well as my personal experience).
My Mazda 2021 infotainment screen goes goes out usually when hit a bump and stays out until it sits awhile. Which when this happens there is no backup camera which is a safety issue. The Mazda dealership said it was the screen which they wanted $2900 just for the screen so I got one off eBay and it's still doing the same thing. Which I think its the CMU
2021 Mazda cr-5 Automatic rear hatch comes open on its own. This has happened 6-7 times. I make sure the car is locked and have come back to parking lot to find the hatch open. I have even locked the car and when I have walked to door of Walmart (long way off) and look back the hatch is not open. When I come back out, the rear hatch is open. I took to dealership and they could not rectify the problem.

Screen blank when I am drving a while without any problem. I saw online and many owner have same problem. I followed company and online instruction. the problem could not be solved.
Radio audio randomly stopped working and you have to disconnect the negative or you have to leave the car off essentially all night. It’s definitely unknown issue there’s videos all over YouTube about it and there’s forms on read about it.

Important note for snowing conditions: The radar for adaptive cruise control is located in the front Mazda emblem. Snow buildup on the emblem can block the radar's signal and disable the adaptive cruise control system when driving. A heating element is necessary to prevent snow accumulation and maintain functionality.
tires 1 complaint shown
We took our car to the Mazda dealership for routine maintenance. The technician found circumferential cracking along the sidewall/tread junction of all 4 tires. We were told that this suggests tread separation and that we should not continue to drive on the tires. We replaced all 4. I have pictures of all 4 tires.
