2021 MAZDA CX-5 Engine Problems

Car purchased new in 2021. Uses 1quart oil every 3,000 miles. Checked at dealer and assured of no leaks. Service bulletin issued by Mazda acknowledges problem probably due to faulty valve stem seals, but no resolution offerree for clients except “stop by for a quart of oil whenever light comes on!”

Engine oil consumption - around 2000 miles after oil change.

Motor using excessive amount of oil. Vehicle has just turned 20,000 miles. Uses a quart of oil ever 1500 miles or so.

Low oil light keeps coming on before it’s due. Went to dealer and they gave me a notice of a bulletin. 01-012/21. It states there is an issue where the engine leaks oil faster and could eventually cause engineer damage. They are asking us to come in more frequently for oil changes or to top off. Unknown what the fix is and it’s been on multiple new Mazda vehicle types.

Engine burns about 1 quart of oil ever 5000 miles since new.

Excessive oil consumption on brand new vehicle 1qt after 3800 miles

Excess oil consumption. Manufacturer recommended oil change interval is 7,500 miles. At 3500 miles a low oil warning light came on and I had to add oil. I changed my oil as recommended at 7500 miles. At 11,000 miles the warning light came on and I had to add oil once again. I am currently just shy of 15,000 miles and I'm getting my oil changed tomorrow. I've read that there is a known valve stem seal issue with these 2021 turbo engines that is causing this. I'm worried that there may be a catastrophic engine failure that could cause me to crash.

My check oil light has come on 3 times in between my first and 2nd oil changes. Added a total of 1 1/2 quarts between the 3 oil changes. Made the dealership aware of this last week at 2nd oil change. They’ve begun to monitor my mileage with my oil consumption and I’ll go in every 500 miles so they can document.

Oil burning and leaking as well after only 14,500 miles. I see there is a Class Action lawsuit filed against Mazda in late May of 2022 regarding faulty oil stem seals that cause oil to leak into the combustion chamber which will eventually cause O2 sensors to fail, catalytic convertors and engine valve failure. Dealer acted like they never knew about this issue and initially told me it was "normal" while the engine breaks in to burn oil. They attributed the "leak" to a faulty oil filter they put on during my recent oil change on July 8. Ridiculous that a brand-new car burns and leaks oil. Massive cover up by Mazda and a recall should be demanded. Apparently, they either do not want to spend 1000's of dollars in recalls or they do not have a fix. Either way, not owning up to this is a travesty and injustice!

Excessive oil consumption. After 3,000 miles driving, need to add a quart of oil as ‘oil low’ light comes on. Vehicle is 1 year old, and this happened at 3,700 miles on the odometer. Has happened after every oil change at around 3,700-4,200 miles driven.

Excessive oil consumption NEW 2021 MAZDA CX-5 CARBON ADDITION TURBO - At approximately 7000 miles the low oil light came on, I added oil and got an oil change 2/11/22. At 11000 miles got low engine oil light had to add a full quart on 7/20/22. There are no oil leaks or obvious damage anywhere. I contacted the dealer who stated that they recommend oil changes at 5000 miles though the manual states 7500. If oil is being blown through a gasket or seal it will potentially foul the o2 and emissions sensor, the cylinders, etc. and ruin the engine or cause catastrophic failure.

While beginning to turn into an interstate exit lane, all dashboard lights lit up, the engine died, and the car stopped. Power brakes & steering were inactivated. My husband was able to coast the car to the shoulder. My Mazda app said nothing wrong with car. Waited 3 hours for tow as we were out of state. The Mazda dealership found the high pressure fuel pump to have a malfunction. Two different technicians at the dealership related that Mazda was aware of the issue & had not yet issued a recalled.

July 6, 2021 Low oil light came on and I stopped to check oil and it was down 1quart. Then added oil. Miles on car 28,734. I always have oil changed every 5k miles and this was between oil changes. Happened 3200 miles into my next oil change. Mazda has a TSB out in reference to these engines and the TSB is TSB NO 01-012/21 Dated October 4, 2021. It states that Mazda is aware of the problem and as soon as they identify the root cause a complete repair will be made. I will be bringing vehicle into dealer for an oil comsumption test in the next 1500 miles when my oil change is due. The dealer does know there problems with these engines stated in the TSB. My safety and all others are good. On the Mazda Forum there are many complaints and I mean many complaints on...

On July 4th when car had only 10,300 miles driven on it, oil light came on. Oil level was down over 1.5 quarts. Car was not due for an oil change for another 1800 miles.

Low engine oil level light & status is coming on for our 2021 Mazda CX-5 turbo. It has 9115 miles and still 1300 miles away from needing oil change. I called our dealership today & was informed we were the 2nd to call today with message. They provided no further info. I have since found there are technical bulletins regarding this issue. Recalls need to be made & Mazda should be covering all repair costs for this.

Car is burning oil. The low oil level light has come on twice, requiring additional oil be poured into the engine between oil changes. Appears the car is burning oil.

When the cylinder deactivation system triggers It causes the engine/car to shake and stutter. Somtimes it's suttle and other times if feels like the car is going to stall out. It's a vibration that makes it feel like your driving over cobblestones. This has been ongoing for a few months now. I'm taking it to the dealer tomorrow. It appears to be the same problem as the 2018-2019 Recall.

The contact owns a 2021 Mazda CX-5. The contact stated that while stopped at a stop sign, the vehicle failed to accelerate while the accelerator pedal was depressed. The contact restarted the vehicle and corrected the failure. The vehicle was taken to the dealer. The dealer performed a Special Service Program (SSP) Recall #: SSPC7 (TCU Connect Concern CV/Battery) where the TCU software was updated; however, the failure recurred. The manufacturer was made aware of the failure and informed the contact that there was no additional recall associated with the VIN. The failure mileage was approximately 300.

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...

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.

On 17-MAY-2021 after sitting unused for 1 day my Mazda CX-5, mfg year 2021 with about 1,500 miles did not start. All electrical systems failed, there was no indication of any power present. The vehicle is presently at the dealership it was purchased at about 90 days ago, 495 Mazda in Lowell MA and is available for inspection. The sudden loss of all electrical systems has the potential for stranding the driver and passengers in dangerous locations. The problem has not yet been reproduced. The vehicle has been inspected by the service department of 495 Mazda in Lowell MA who advised they had charged the battery and tested it as ok and offered to return the vehicle to me. There were no warning lights or other indication of this problem. This morning when I called for service, the dealer, 495 Mazda informed me they do not pick up failed automobiles...
