At approximately 5,612 miles, the low oil pressure light came on. After changing the oil, it happened again at 7,760 miles. Both times the light came on, the oil level was low.

Car has 13000 miles and is consuming oil
Upon exiting my local car wash, I drove my car around to the area used for vacuuming. I pulled into the parking space and when I applied the brake pedal to stop, the car suddenly accelerated and crashed into the wall of the building. I have the Car Wash Security Camera footage of this incident. It shows my brake light is ON at the car's point of acceleration and my brake light is ON at point of impact with the wall. If you need to review it, I can email it to you.
Detected slight odor of burning oil while highway driving, mileage approximately 8,650. Three days later “low oil level” warning light lit up, mileage 8928. Allowed car to rest and checked oil level manually. Oil level was slightly above the minimum required. No signs of oil on garage floor.
Low oil light came on 4500 miles after oil change. Engine used nearly 2 quarts of oil quarl in that distance. Engine burning excessive amount of oil. No oil leaks. Burning oil internally. Reported to dealer.
Vehicle has had excessive oil consumption. Engine consumes approximately one quart of oil every 4k miles or so with normal driving not spirited. Vehicle has no visible signs of outward leaks. First oil change was at 5030 miles with approximately 5.2 quarts of Castrol edge full synthetic oil and a Purolator boss oil filter PLB14612. Vehicle currently has 9352 miles. I have not let it get to a point where oil light comes on, but it has been to the quart low dot on the stick twice so far. This should not be normal. This has not been confirmed by a dealer or independent service center as I maintain the oil checks and oil changes myself. Tailpipes do have black soot inside but is not greasy or oily. I haven't noticed a lot of smoke from tailpipes just a small bit of whitish vapor that quickly dissipates when my wife pulls it out of the driveway and starts off down the road that I contribute to normal condensation, but I nor she can see tailpipes when we are driving a longer distance of course. I haven't smelled oil burn or seen any leaks on driveway, but the oil is going somewhere. I have seen a TSB from Mazda about possible valve stem seal problems with my VIN number. I hope Mazda will resolve this within my warranty as oil consumption can cause other major engine component damage down the road i.e., catalytic convertor, oxygen sensors, carbon deposits, etc.
Engine oil light indicated low oil level at 6000 miles. Dealer states there is a TSB on this issue but no repair process is available.
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.
I bought a 2021 Mazda CX-5 from Ramsey Mazda of Des Moines, IA. It offered comparable comfort & features. A selling point was the safety features touted by the salesman. Odd things occurred during the first few months but I attributed it to a learning curve. I saw some odd messages but I really did not think it was relevant until June 28, 2022. I was backing out from a parking space. The Blind Spot Monitoring failed to indicate a car approaching from the right that then stopped in my blind spot. I hit the car behind me. Despite the fact, I understand personal responsibility, I never would have had the BSM worked correctly. I dropped the car off on July 15, 2022 to the Ramsey Mazda Service Center after the BSM failure and a Check Engine Light appeared. I already had the Ramsey Mazda Collision Center look at the car and told them of the of the BSM failure. That man doing the estimate said he had heard of those failures before. On July 15, I dropped the car off at the Ramsey Mazda Service Center to look at the BSM, a Check Engine light, the door locks and the hatch opening on its own. I tried to tell the Service Center that there was something severely wrong with the electrical system in this vehicle. I have a witness to its erratic behavior, but I was continually dismissed. There is more wrong now with my car than when I left it with the dealership. They kept my car for 19 days. During the 19 days, I continually had to call and check on the status of my vehicle. Ramsey Mazda wa
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.
Oil consumption issue with the 2.5T motor. Engine is burning oil at an accelerated rate.
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.
The contact owns a 2021 Mazda CX-5. The contact stated that the vehicle was consuming an excessive amount of engine oil. The contact stated that after driving for 1,000 miles the vehicle needed an oil change. The oil level warning light would be illuminated. The contact stated that after the vehicle was taken to the dealer the contact was informed that the engine was a quart low on engine oil. The manufacturer was made aware of the failure. The approximate failure mileage was 4,000.
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 this exact same issue I'm experiencing with this vehicle. People are extremely frustrated and getting excuses that this is just normal for these engines to use a quart of oil every 3 or 4 k miles. I don't agree and this is not normal.
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.
On April 16, 2022, around 6:45PM, I drove my new Mazda CX5 (@ 3500 miles) into our church parking lot and turned right down the first row of cars. It was light out and the weather was pleasant. I turned right into a parking space with my foot on the brake. The car was facing and perpendicular to a sidewalk that was about 10 feet away. It was separated by a grassy median. When I depressed the brake further to shift from drive into park, the car surged forward and accelerated. There was a pedestrian on the sidewalk in front of the car. I turned the wheel to the right at a 90 degree angle to avoid hitting her. I kept pressing the brake but the car kept accelerating until it crashed into a large tree. The airbag deployed. Both the pedestrian and I were transported to the hospital. The pedestrian had bruises on her leg and hip, but fortunately was not more seriously injured and was released from the hospital. I was admitted to the hospital for contusions to the heart. The car hood was crushed and the car was totaled. The incident was terrifying. The police estimated the car went from nearly a standstill to about 40mph in about 15-20 feet. There were no warning lamps or messages prior to the accident. I checked the NHTSA website after the accident and downloaded 16 similar complaints where low mileage Mazda CX5s accelerated out of control when drivers were attempting to park or stop.
BSM Does not see all vehicles in the blind spot. It is very inconsistent. I have taken it to the dealer who told me that they could not repair it because no fault code shows up. Mazda has not been helpful.
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.
I parked my car in my driveway and accidentally left the gear in park when I turned off the engine with the push button. This is the first time I had driven this car so I didn't know what to do for the warning beep. I exited the car and took the key fob with me. My daughter exited the car just after me and when she closed the car door the pressure was enough to start the car rolling backwards. The vehicle rolled down our driveway which has a steep slope, across the street, over our neighbor's yard and crashed against their house. We are lucky that no pedestrians or other vehicles were involved. There is significant structural damage to the neighbor's house. A police report was filed. I believe this is a significant safety hazard that a driver could turn off the engine and leave with the key fob while the car is in drive and there is no braking mechanism to prevent the car from rolling! In addition, the quiet warning beep should be more pronounced such as the horn honking or something more extreme to get the attention of the distracted driver.
The windshield defrost only works for the center part of the windshield given that there is only a single center defrost vent. Vision is severely impaired during rainy or snowy days (worse during nights) while driving and it makes the driving very dangerous. You can only see what is in front of you, but very limited side views due to the fog on both sides of the windshield. Attached is a pic of the windshield when I came back from a 2 mile errand run while the defrost vent was at full scale constantly.
The blind spot monitoring system does not function properly. While on the freeway some vehicles show up and some do not. I took it to the dealer, and they test drove it and said it was working properly and there were no codes. I contacted Mazda and they made a second appointment for me, and I took it back. I told them that it only does it on the freeway and I sent them a video showing the problem. They said they drove it again (not on the freeway) and told me it worked fine and since there was no code, they could not fix it. I called Mazda again and they told me they could make an appointment at another dealer. The nearest dealer is an hour away and they had my vehicle for 7 days the first time and three days the second time. I don't have the ability to take it an hour away and leave it for days. This is a safety issue and needs to be repaired. I had the same vehicle only it was a 2018 and never had this problem.
On this model of Mazda, they only manufactured it with 1 small center defrost vent on the windshield, and nothing on the sides. Therefore the windshield only gets defrosted in the center, not in front of the driver. I live in the Pacific Northwest and it rains a lot which results in foggy windows, I feel it is extremely unsafe driving a car that doesn’t defrost the full windshield, more importantly in front of the drivers view. I have severely degraded visibility 80% of the time I’m driving because of how poorly designed defrost ducts are
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 brought the car in on 12/22/21 and was told the car was low on oil and nothing else could be done until Mazda comes up with a solution.
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.
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.
The contact owns a 2021 Mazda CX5. The contact stated that the fuel gauge was not operating properly. The vehicle was taken to the dealer and the dealer reprogrammed the Transmission Control Unit (TCU). However, the failure recurred. After taking the vehicle back from the dealer, the contact was driving at an undisclosed speed, when the windshield wiper inadvertently engaged, and several unknown warning lights illuminated. Additionally, the headlights inadvertently turned off and the steering wheel pulled the contact's arm down and the vehicle went to the median, running over a metal pole. The cruise control would not deactivate, and the brakes would not engage immediately. No injuries were sustained. A police report was filed. The vehicle was taken to another dealer, Hiley Mazda of Huntsville (6934 Hwy 72 W, Huntsville, AL 35806). The dealer measured the fuel level resistance range of the fuel level sender and informed the contact that the fuel level sending unit needed replacement. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 1,629.
The design of the remote control is poor. Placement of the buttons on the side and the light pressure needed to activate the unlock for the trunk has led to it opening unexpectedly. It can open and strike a pedestrian when you did not intend to activate the powered trunk open feature. It could also open when near an object and damage the trunk b/c of how sensitive the remote buttons are. This has also led to the doors unlocking b/c of placement and light pressure needed to activate. On one occasion the button was pressed accidentally and the trunk was partially open as I backed up.
Primary hood latch released while driving. It happened at night in heavy rain and was not seen. This vehicle appears to lack a hood open warning indicator. I am unable to find it in the manual. There is an indicator for doors and back hatch but not the hood. Had the secondary latch failed, this could have had a catastrophic outcome.
The contact owns a 2021 Mazda CX5. The contact stated that after the vehicle was serviced at the dealer under Manufacturer's recall number: SSPC7 for the TCU, the contact was driving at an undisclosed speed, when the "Keyless ignition malfunction" warning light was illuminated. The contact was able to drive to his residence, but when he attempted to turn off the vehicle, the vehicle would not turn off. The contact had to disconnect the fuel pump fuse for the vehicle to turn off. The vehicle would also not turn on when the contact attempted to start the vehicle. The dealer was made aware of the failure and informed the contact to contact the manufacturer for assistance. The vehicle was diagnosed and repaired. The manufacturer was made aware of the failure and informed the contact they would send for a tow truck, but the tow truck never showed up. The failure mileage was approximately 4,400.
We have a new 2021 CX5 and the two taillights (the ones that are on top of the backup lights) do not light up. The dealer, Napleton Mazda in Libertyville, IL, told us that that is normal and those lights are not meant to light up. The dealer said they have many customers bringing their car in for service for the same issue, but it is not something they can fix. At night the car is not as visible as it should be, especially if you are in a dark area and stopped without your foot on the brake. We had the police pull over my daughter in the car saying she had no lights in the rear. This is not on all these models, but we were told this particular model doesn't have the lights, even though the light kits are installed.
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 and I should either call Mazda roadside assistance or jump start the car and bring it in. I measured the battery voltage at 2.5 volts and charged it with a high quality battery charger. The car then started. After shutting off the car there was a faint buzzing sound from the engine compartment. I advised the dealer service department of all these details. I would also note that after the car started I measured the battery voltage at over 14 volts proving the charging system works, after shutting off the engine the voltage dropped to 12.1 volts.
I WAS DRIVING ON THE HIGHWAY AT ABOUT 65MPH AND HEARD A LOUD POP. I WAS UNSURE WHAT IT COULD HAVE BEEN, BUT KNEW IT CAME FROM THE ROOF AREA. I OPENED THE SLIDER TO THE SUNROOF. THE GLASS HAD EXPLODED!! I PULLED OVER TO ASSESS THE DAMAGE AND NOTICED THE GLASS EXPLODED OUTWARD. I HAVE PICTURES SHOWING THE HOLE IN THE GLASS AS WELL AS THE SHARDS (HELD TOGETHER BY SAFETY COATING) POINTING UP AND AWAY FROM THE CAR FROM HAVING EXPLODED OUT.
THE INFORMANT CONTROLS ARE NOT SAFE TO USE WHILE DRIVING. WAY TO MANY SUB GROUPS TO SCROLL THROUGH JUST TO GET THE RADIO TO WORK. VERY CONFUSING AND DISTRACTING.
THE PAINT ON THIS CAR IS NOTORIOUSLY POOR AND MAZDA IS AWARE. WE PURCHASED THIS VEHICLE ON 16 FEBRUARY 2021, DROVE IT HOME AND LEFT IT IN THE DRIVEWAY DUE TO SNOW/ICE. ON THURSDAY, 18 FEBRUARY INSTEAD OF BRUSHING OR SCRAPING OFF THE ICE WE LEFT IT TO MELT. UNFORTUNATELY, THE ICE MELT LEFT HUGE SCRATCHES ON THE HOOD. THERE IS NO REASON FOR ICE/SNOW TO CAUSE THIS MUCH DAMAGE. WE REVIEWED A NUMBER OF WEBSITES AND IT APPEARS THAT MAZDA IS AWARE OF THIS INFERIOR PAINT AND HAS DONE NOTHING TO RECTIFY THE PROBLEM. BUT THEY DO CHARGE $595 MORE FOR IT. I HAVE NOT RECEIVED ANY CALL BACKS FROM MAZDA CORPORATION. BROWNS CHANTILLY DID ATTEMPT TO REPAIR THE DAMAGE BUT ALL THAT DID WAS MASK IT SLIGHTLY. THE DAMAGE IS STILL VERY VISIBLE. THIS CAR HAS 12 MILES ON IT AND MOST OF THOSE ARE FROM THE DEALER. I AM UNABLE TO UPLOAD MORE THAN ONE PHOTO. THE PHOTO SHOWS THE LARGEST SCRATCH BUT T HERE ARE MANY MORE ON THE CAR.
WE BOUGHT THE CAR NEW OFF THE MAZDA DEALERSHIP LOT YESTERDAY WITH 5 MILES ON THE ODO. AS MY HUSBAND PULLED OFF THE LOT HE SMELLED A BURNING SMELL AND THE BRAKES FELT LIKE THEY'D SEIZED UP A BIT. HE PULLED OVER AND THOUGHT ABOUT TURNING BACK ONTO THE LOT, BUT THEN THOUGHT IT MAY BE JUST BECAUSE THEY'RE NEW BRAKES AND CONTINUED ON AND DROVE HOME. THIS MORNING WE REMOTELY STARTED THE VEHICLE AND THE MAZDA APP SENT US AN ALERT THAT THERE IS A CRITICAL VEHICLE MALFUNCTION HAVING TO DO WITH THE ANTILOCK BRAKE SYSTEM. THE DEALERS ARE CLOSED, SO I DON'T HAVE ANY MORE INFO YET. I JUST SIGNED BACK ON TO THE APP AND THERE'S A SECOND MALFUNCTION ALERT NOW WITH THE EMERGENCY LAND KEEPING. THERE ARE NOW CURRENTLY 65 MILES ON THE ODO. WE HAVE ONLY DRIVEN THE VEHICLE FROM THE DEALERSHIP HOME AND PARKED IT OUTSIDE OVER NIGHT.
RED SOUL ON THE CX5 HAVING EXCESSIVE PAINT CHIPPING. LESS THAN 5K MILES ON THE CAR AND HAVE ONLY HAD FOR 3 MONTHS AND THERE'S ALREADY 9 TO 10 CHIPS ON THE HOOD AND DRIVER DOOR.
