2021 Mazda CX-30 Complaint Log

The Low Oil Level light/sensor came on before it was time to get an oil change (the recommended 4600 miles). This is super dangerous as it can cause major engine issues. I took it to the dealership and the dealership stated "they are having problems with these cars-they are burning too much oil so there is going to be a replacement valve once they have one made and you'll need to come back in to have it replaced -it will be a big job since it's part of the engine".

Low Engine Oil displayed on dashboard after only a couple thousand miles/four months from last oil change service. Known issue with this year/model for a year (https://static.nhtsa.gov/odi/tsbs/2021/MC-10203724-0001.pdf), but no recall or fix has been offered other than topping off or changing the oil. The dealer did top off the oil for free as the notice says.

I am constantly receiving a “Low Battery Voltage Warning” for reasons as simple as leaving my door or trunk open for 10 minutes. I never leave my car in accessory mode to play music or anything that might drain the battery. It happens several times a month for no reason. I have not had it die on me yet, but I don’t know if it’s actually a low battery or software glitch.

Identified low oil level with 5,500 miles on the odemeter. No leak detected. The car has been babied; no accidents or undercarriage damage.

Losing/burning oil with no leaking - less than 8,000 miles. Mazda has issued a service bulletin on the issue but offers no actual repair solution. Could be dangerous if engine seizes while in operation.

Low engine oil light came on after 3 months of driving. I know this is a common issue on the turbo model, yet there has not been a recall.

Purchased this car on Saturday August 13th from a dealer. Last weekend on the 20th the low engine level warning came on. We checked the oil and it was at the lowest dot on the dipstick. We added one quart of oil. This car isn't even due for an oil change it shouldn't be losing any oil.

engine oil low light coming on within 3000 miles of oil change

Engine is consuming/burning oil. I have needed to add 1 qt of oil every 3-4k miles, since purchased new. Car now has 25,000 miles and I have added oil 6 times. Ive called the dealer(Classic Mazda in Mentor Ohio) and they insist this is normal and there is no issue with the engine. Yet, I read on the internet that this is a known problem.

Oil warning light came in at 5,500 miles. Dealer says they know the engine consumes oil.

I have just about 8800 miles on my Mazda CX-30 Turbo after a year and 5 months. Suddenly had my low oil engine light come on. I pulled over and the oil is barely on the tip of the oil stick. My last oil change, which was also my first, was completed at 4937 miles from the Mazda dealership.

Yesterday I heard a very light ting sound. I did not think much of it. When I stopped I checked for any windshield damage, I could not locate any. After having the car parked for several hours, to my utter shock I had about a 1' long crack in my windshield. After looking for some time, I located the microscopic chip that caused the issue. I believe the windshield is defective! It is either too thin, too brittle, or both. Which could be a safety hazard.

low oil indicator keeps coming on at 3k miles and 8k miles. some times the oil is slightly low. The manual says to sop driving immediately, but that is not always possible.

The automatic braking engaged without warning and without cause. There was nothing directly in front of the car that was a possible collision threat. I suffered a neck injury as a result of the force in which the car stopped. Fortunately the driver behind me was able to stop. The car was taken to the original Mazda dealer and I was told this is a problem with my car but that they had no permanent fix, nor the ability to permanently shut off this system available until "corporate got back to them." They did not provide any paperwork and stated "we will call you when we have something." I now have a car I am scared to drive.

Continuous oil loss from engine. No leaks but oil level diminishes and warning lights come on monthly.

Driving home from work today I got a "low engine oil level" alert/warning. First time this has happened. I have approx. 15,500 miles on my vehicle and it was serviced on 3/22/22 (11,828 miles). That service included a full oil and filter change. I see it has been noted that there is an oil leak with this particular vehicle but Mazda has not been able to figure out what is causing it. Just wanted it to be reported

Low engine oil light came on at 8990 miles. Bought vehicle brand new. Has occurred before with this same vehicle. Excessive oil consumption is a known issue with this make/model

Randomly accelerated on its own; burns oil- low oil levels twice in 6 months; randomly says cruise control is available under 25 mph when car is traveling at highway speeds; the unlock and lock functions randomly fail; lift gate randomly opens; alarm system randomly goes off; TERRIBLE fuel economy (18-21 mpg)

Low engine oil pressure light came on forcing me to stop driving the vehicle. Upon investigation, engine oil level was a full quart low of oil, despite no leaks and only having 8000 miles.

Low engine oil after 4630 miles!

The windshield in my 2021 CX30 had a distorted view on the passenger side of vehicle. Took it in to dealership who confirmed that there was obvious distortion in the windshield. Windshield was replaced and the new windshield has the same issue. Mazda is now saying that it is "normal" to have some distortion on this particular model and they will not replace the windshield again.

I have the 2.5 liter turbocharged engine in my CX-30. It currently has approximately 18,000 miles after a little over a year of ownership. So far I have had to put in 3 quarts of oil in that time. The engine/low oil indicator comes on about every 4,000 miles. When I check the oil, it shows that it is down a quart. I have taken it in for regular service (oil and filter, tire rotation) twice now, and have brought this to the attention of the service advisor who tells me that this is normal for turbo engines. I disagree with this assessment. I will bring it up again later this week when it goes in for its third service. No new car should consume oil at the rate this one does. I have also observed blue smoke from the exhaust on start-up. I owned another turbo Mazda model a few years ago that did not do this. I have found what appears to be a technical service bulletin from Mazda regarding all turbocharged 2021 models built prior to September 2021. (TSB-01-012-21) My greatest concern is that this will only become worse and end up causing major damage to the engine and/or make the car unsafe to drive.

Notable distortion in the windshield horizontally through driver and passenger areas. Dealership has been helpful in replacing the windshield three times thus far. The most recent windshield is clearer but still with notable distortion and is considered an aftermarket windshield. Mazda is aware of the issue and was told they are giving pushback on replacements. This issue is noted numerous times on multiple Mazda forums with no solution. From conversations with the dealership, Mazda is claiming this is normal especially close to the pillars due to vehicle design. This issue causes driver fatigue and distance perception problems while driving which is considered a road safety concern. Paperwork and vehicle are available for inspection upon request.

I purchased a Mazda CX-30 October 2021 - in April of 2022 the oil light came on mileage 4,672 and I decided to have just have the oil changed at Hello Mazda of San Diego. They said they wouldn't charge me for the oil only the service charge. And mentioned that something is wrong and will top the oil off at no charge in the future. Last month in November I took a short trip to Tucson AZ to visit family the oil light came on once again mileage 10,079 I brought the car into Jim Click Mazda Tucson and after several hours I got the car back. They had topped off the oil with no charge. I asked how low the oil was. The service man quickly said just a little low under a quart. I didn't want to argue with him- but I checked the oil stick, and it was below a quart and I know a light most likely won't come on without it being at least a quart low.

Excessive oil consumption. I bought this vehicle new from a Mazda dealership, with factory warranty. The check engine oil light came on at approximately 6800 miles, 3750 miles after the first oil change. An additional quart of oil was added. I brought it back to Mazda to confirm no oil leaks, which they confirmed. They were made aware of the Mazda service bulletin for excessive oil consumption, which they acknowledged, but indicated they will monitor as there is no solution from the factory.

The car has been reporting low engine oil numerous times between oil changes.

My car is burning a quart of oil every 1500 miles. I have taken it to the dealer three times. They say that they know about the problem but don't have a fix. I am afraid that the engine could seize up during driving, causing a accident.

While driving, Low Engine Oil light illuminated. Vehicle has 9968 miles at time of incident and had one oil change at 5873 miles. So in the span of 4095 miles, engine had burned enough oil that none was showing on dipstick at time of incident. Vehicle was taken to dealership where it was confirmed that there were no leaks and the engine was consuming oil at a rapid rate. Mazda has issued a bulletin to dealerships concerning this issue, so the company is aware a problem exists with this engine. Had the oil level decreased to a low enough level, the engine could have feasibly failed, which could have resulted in a dangerous situation if it happened on the highway or in heavy traffic. Mazda currently has no fix and encourages that oil be added when necessary. Given the unpredictable frequency of the oil consumption, this does not feel like a safe solution, putting the onus entirely on the owner.

At about 3,605 miles, I received a low engine oil warning. The car is only 4 months old. When i took the car to the dealer, apparently there is a TSB that was issued in October 2021 about the problem. I bought the car in November was not advised of this issue. At this time, it appears at this time Mazda is unable to determine the root cause. It appears that I am to take the vehicle to the dealer every time I have this experience. I am worried about the potential impact and the lifespan of the engine.

The low engine oil warning light keeps coming on, and there’s appears to be no visible leak. I add about a quart each time this happens and it does fine for a while. The last time I took it to the dealership, I told them about it. They just said they didn’t see a leak and not to worry about it. Ultimately the issue is how will this impact the longevity of my engine?

Multiple warning messages came on including "Pus button start malfunction. Have the vehicle inspected." "In-vehicle network malfunction. Have the vehicle inspected." "Auto light system malfunction. Turn on/off lights manually." "Power steering malfunction. Have the vehicle inspected." "Driver attention alert disabled." Vehicle would not start after this and had to be towed to a Mazda dealership.

Purchased Mazda CX-30 Turbo car new March 31, 2021, in Jan 2022 low oil light came on with only 5,000 miles. Dealer noted it was 1 qt low. Just prior to reaching 10,000 miles the low oil light came on again. This car is burning oil with normal driving; primarily from rural area into town 15 min away or freeway driving. This creates an unsafe situation with parts and engine failure.

Manufacturing defect in the windshield glass: distorted/warped windshield glass causing waves/ripples. Result: impaired visibility when operating vehicle and rapid eye fatigue. Google search (forums) indicates that this is a well known issue on several Mazda models. The issue presumably existed at factory. I noticed upon purchase as CPO at 6k miles. Available for inspection if needed.

The contact leased a 2021 Mazda CX-30. The contact stated that the vehicle had failed to start up after multiple attempts with several unknown warning lights illuminated on the instrument panel. The contact stated that an unauthorized independent tow company towed the vehicle to a dealer two hours away from her home and that the vehicle was stolen from the dealer's lot. A police report was filed. The contact then stated that the vehicle was recovered and returned to the same dealer.

There is a warp in the windshield on the driver's side of the car that causes noticeable distortion. It causes eye pain and headaches. It also causes distortion and visibility issues when driving at night.

The contact owns a 2021 Mazda CX-30. The contact stated that while at a stop sign, the vehicle was bouncing up and down. The contact mentioned that the failure recurred multiple times and only while the vehicle was stopped. The dealer was contacted but was unable to provide a diagnosis. The vehicle was not repaired. The manufacturer was not notified of the failure. In addition, while driving at approximately 8 mph, the brake assist warning light illuminated, and the brake assist applied independently while there was nothing in front of the vehicle. The approximate failure mileage was 3,500. As of November 5, 2021 the mileage was noted as 6,301 by Manchester Mazda. The vehicle would start bouncing up and down and moving forwards and backwards while stopped at a stop light and this occurred multiple times shortly after the purchase, within a month of purchase and randomly continued up to the point of the following issue. Consumer had shut off the brake assist every time she was driving there have been no more incidences. In addition, having the winter tires put on stopped the incident from recurring.

The brand new vehicle was sold to me on 2/23/21 with an open safety recall. This recall was finally addressed on 5/21/21. At no time did Mazda north American operations formally notifying me of the safety record. 1) how could this happen? 2) has this shortcoming been remedied? 3) Will I receive formal notifications of future safety recalls on a timely basis?

AFTER TURNING LEFT AT A SIGNALED INTERSECTION ONTO A HIGHWAY THE AUTOMATIC BRAKING ENGAGED AND THE CAR SKIDDED TO A STOP IN THE MIDDLE OF THE LANE. LUCKILY NOBODY WAS BEHIND US. THERE WAS A CAR ABOUT 4 CAR LENGTHS AHEAD THAT WAS GOING THE SAME SPEED AND WAS NOT STOPPED. I PULLED OVER AND CHECKED THE FRONT SENSOR AND NOTICED A COUPLE BLACK FLIES ON IT AND BRUSHED THEM OFF.

Sudden, enexpected emergency braking when there was no vehicle or any other obstruction in front of me. Luckily, the distance between me and the car behind me was great enough to prevent me from being rear ended.
