2018 Mazda CX-5 complaints

Despite a recall on the fuel pump, there continues to be a problem but instead of the “back” fuel pump that was fixed, the “front” fuel pump seems to be having the same issue. When taken to the dealer, the code P0087- fuel rail/system pressure too low shows up. This is causing car to stall, unable to pick up speed or simply pick up too much speed when attempting to accelerate. It’s a safety hazard for a car less than 6 years old.

Noticed an oil smell when driving the vehicle, slightly premature to when it was due for an oil change. Engine was emitting light blue smoke when parked after driving for more than 20 minutes. Took the car to a Mazda dealership to get serviced two days after noticing the issue and was told that the cylinder head was cracked and needed to be replaced. There was oil leaking from the vehicle, which I had not noticed, and it had soaked a lot of the front undercarriage of the car. Research into the effects of an oil leak indicate that it can cause a serious malfunction of the engine and other components of the car, but I did not experience that in the time of noticing the problem and taking the vehicle to get serviced. The problem was diagnosed by the service department at a Mazda dealership and is being repaired there. The oil indicator came on a day after noticing the smell.

Noticed a burning oil smell coming from the car along with leaking oil in the driveway. Vehicle has 53000 miles on it and was 3 months out of powertrain warranty but still under the 60000 mileage cap. Local Mazda dealership came back saying that it was a "SA-037/23 Oil leak at cylinder head, cylinder head replacement with parts kit" and quoted $5100 to repair. Dealership stated that the vehicle was unsafe to operate. There were no dash indicator lights or symptoms of overheating to indicate that there was a problem outside of the smell. After the diagnosis was made, we researched and found that this was a commonly reported problem for this model year

The cylinder head and timing cover are leaking oil and need to be replaced. It is at the dealer and available for inspection. The car started smoking and lost oil obscuring my vision. The problem appears to be well known by the dealer and they were able to diagnose the issue. The vehicle has only been inspected by the dealer where I purchased it. There were no warning lamps, messages or other symptoms. This vehicle has had regular maintenance per the manufacturers specifications since it was purchased new.

Oil started to leak along with a burning smell, ended up being a cracked cylinder head at 77k miles. It was not in an accident & it did not overheat. But it appears this is a known issue with this make, model & year. Now Mazda only wants to pay $1k of $5k charge. I bought the dealers extended warranty, up to 75k miles, which apparently means nothing. My next car will not be Mazda.

Cracked cylinder head at 75000 miles causing oil to leak, Mazda dealership called it a fire risk

Head cracked at just under 49,000. Oil dripping on exhaust entering cabin continuously. This issue was identified by Mazda to dealers in 2021 via Mazda TSB SA-031/21. Despite having our vehicle serviced multiple times at the Puyallup Mazda dealership after that date, no mention was made of this noted defect. We drove for about a month inhaling the petroleum fumes often thinking it was from trucks ahead of us on road. Dealership replaced the head assembly but since car was 4 months out of warranty (we are the original owners having purchased it new from this dealership) the dealership insisted on charging us for repairs. We've been breathing fumes from a known issue and others may be as well due to faulty manufacturing the manufacturer and dealer refuse to take full responsibility for.what is clearly a defect.

2018 Mazda CX-5 with roughly 52,000 miles on it was emitting a burnt rubber smell and white smoke from the engine. Repair shop thought it was a bad timing lock. Replaced that and car continued to emit white smoke and smell like burnt rubber. Engine then began leaking oil. Took the car back to the repair shop and it was confirmed that the engine had a cracked cylinder head. The repair shop said this is a known issue with 2018-2019 Mazdas. In three days time, the engine leaked roughly 1 quart of oil and was deemed not safe to drive by the repair shop.

My 2018 Mazda CX-5 had a rubber burning smell and smoke leaked into the cabin. I noticed the next morning, oil leaked onto my driveway. I brought the car to the dealership and they mentioned it was a cracked cylinder head. My car has approximately 49,200 miles on it and it about 5.5 years old. It is under the mileage limit for powertrain warranty but slightly over on the age limit for powertrain warranty. Mazda informed me that they would cover roughly 37% of the repair costs that the dealership quoted me. I've read online on various Mazda forums that many owners are dealing with the same issue and Mazda admitted that a batch of heads have a manufacturing defect. Owners on this forum mentioned Mazda covered 100% of the repair costs for cars that were out of warranty due to this being a known manufacturing issue. I think the proposed coverage that Mazda provided me is insufficient.

There a oil leak either engine cylinder crack or head gasket leak and the car only has 53000 miles when warranty just expires. After searching on the internet, there seems to be many similar cases. Mazda should recall this issue.

There was a TSB #[xxx] for the repair of Cracked Cylinder Head(s). Our 2018 CX-5 incurred a Cracked Cylinder Head at 5,418 miles. This was under the 60,000-mile power train warranty, but after the 5-year term had expired ([XXX]). Our issue started in late January '24. The car had been serviced at the Mazda Dealership in Hyannis, MA until my wife bought a '21 CX-5 model and gave the '18 model to our college son in FL. The TSB was for '18 - '20 models - which has now been increased to the '23 CX-5s. Mazda US would not help us in any way with the engine replacement that the Mazda dealership in Tampa replaced with a '23, 4,000-mile engine. $ 7,462.89 'new' engine that has a '23 engine that could incur the same issue! Also, my wife's newer model, '21, could also be a lemon for the TSB. We're looking for Mazda to step up for it's (loyal) clients! The work was completed and paid for on [XXX]. Mazda reviewed our case ([XXX]) and declined to assist. A reliable vehicle, Mazda, with an engine at 54,000 miles should be cared for by the manufacturer. The reason the time expired and the mileage was low was due to the lack of driving during the Covid era. We have researched online the number of cases for Mazda and the CX-5's issues with the cylinder heads. We are looking for a government interaction to assist consumers like us.

We own a 2018 Mazda CX-5 which developed a cracked cylinder head after slightly over 53,000 miles. We had oil leaking in our driveway and our dealership advised us not to drive it as this would be an extreme safety issue. I was advised to contact you as this seems to be an ongoing issue with Mazda CX-5's from 2018-2021. There is a safety bulletin TSB #SA-031-21. I am hoping this will help with resolving this with Mazda costumer service.

ENGINE HEAD HAS CRACK ON IT, CAUSING OIL TO LEAK OUT AND BURN AND SMOKE. IN ORDER TO REPLACE THE ENGINE/CRACK, MANIFOLD NEED TO BE REMOVED. LEAKAGE IS IN THE BACK OF THE ENGINE. THIS MUST BE MANUFACTURED DEFECT. MY MAZDA HAS LESS THAN 45000 MILE ON IT. UNFORTUNATELY WARRANTLY IS NO LONGER VALID. UNLESS A RECALLED IS ISSUE, A REPAIR WILL BE FREE OF CHARGE TO CURRENT OWNER. OTHER WISE OPERATOR HAS TO CONSTANTLY KEEP ADDING OIL.

The lighting system on the 2018 Mazda cx-5 base sport model has it so that during the daytime, the low beams continuously run. This and the continuously lighted dashboard make it hard to tell when you need to turn on the headlight/tail lights, since the headlights are always on. These arent even side drls, they are full low-beam lights. I've seen many Mazda cx-5 base models that do not have auto headlights drive around with there without any taillight and makes it dangerous for traffic behind to see the vehicle. Additionally, when others borrow the car, they always never turn on the headlight because there is no indication that anything needed to be turned on unlike older cars where the dashboard is fully black when the headlight/taillight is off.

Hydraulic lift adjuster failure causing loud engine knocking. Vehicle cannot be driven and costs thousands of dollars in repairs. The engine is only at 42,000 miles.

Touch screen malfunctions, causing actions to take place without being touched. The phone randomly hangs up or randomly calls people. The GPS moves the cursor away from the car making it impossible to follow directions. The radio will go to full volume. The screen will change settings randomly. This is very distracting and dangerous, makes drivers more likely to get in an accident. The touch screen itself is rarely used and has never been damaged. This problem has been reported on many Mazda forums and there has been a recall for the touch screen for the years up to 2017, but the 2018 models have the same screens and are also experiencing "ghost touching". Dealers are charging $1200 to replace. Later models also need to be recalled.

Cracked cylinder head oil drips onto exhaust manifold smoke gets into cabin and could cause fire on exhaust manifold car was purchased used 5/22 and with 46732 miles and now has 74000 in 2/24 it is now at central Maine Chrysler jeep where we purchased it having repairs done under extend warrantee that we bought with the car.we spoke with the service department at a mazda dealer and they said it is very common i feel that mazda should recall it passengers should not have to breath oil fumes or risk being in a car fire we are lucky to have purchased the warrantee but without it the repairs would be to cost prohibitive for the average person thanks

Transmission is continuously jerking at lower and higher speeds While driving in traffic or in parking lot areas

Vehicle stalls with three warnings showing at high speeds (over 55 mph) Errors dashboard: 1. Smart brake system malfunction 2. Forward smart brake system malfunction 3. Front radar sensor system malfunction

Vehicle engine has stalled multiple times at low speeds. Vehicle will not restart immediately. In order to get vehicle to restart, gas must be revved while pressing start button to get engine to restart. It appears as if fuel is not being delivered to engine. Electrical components remain functional. Vehicle was inspected by dealer and issue could not be recreated. No issues were found. No warning lights displayed or codes found upon inspection. No symptoms of problem; occurrence is sporadic. It has caused traffic and safety hazards due to stalling in roadways.

-cylinder head cracked resulting in leaking and burning oil from rear of cylinder head by exhaust manifold. Car has since been repaired by Mazda, but pictures are available from the incident. -Car was unsafe to drive due to leaking oil all over road (Environmental risks and hazard to others), black smoke and burning smell circulated into cabin via AC (health risks to passengers). Prolonged driving in this condition would have resulted in loss of oil and further damage to the car and others. -Car was towed to independent service center then subsequently towed to Mazda dealership -Mazda dealership inspected and confirmed that it was a manufactured defect that they have seen with other cars. Mazda has a Technical Service Bulletin (TSB) issued as well. -No warning lamps appeared prior to observed smoke and leak, though it was noticed that the car did jerk slightly at times when stopped at a traffic light

The contact owns a 2018 Mazda CX-5. The contact stated that while driving at approximately 75 MPH, the sunroof glass shattered without impact. The contact stated that the glass shards fell onto her; however, no injuries were sustained. The vehicle was not taken to an independent mechanic or the dealer. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 92,000.

Cylinder crack. Recently got a oil change and driving to work couple days after and smelled oil burning into my cab and smoke coming from underneath my hood. Got to work and opened my hood and noticed large amount of oil on belly and leaking oil from my cylinder. I got this vehicle thru a dealership and when contacted, they stated if I pay $7,500 I could get a trade in!!! After numerous searching, I've found a lot of owners with the 2018 Mazda CX-5 are having the same issue with cylinder heads and no corrective actions. Now I have to pay Mazda (after their defective parts) for their mistakes

Ghost Screen, a very well know issue for Mazda. The screen change on its own, no way to fix it. Mazda recalled all their 2014-16 screen, and the 2017-18 are affected by same issue but they are not taking responsibility for it. Dealership wants to replace the screen, that's over $1,000 repair. Please make Mazda earn their mistake.

The radio (aka infotainment system) goes crazy sometimes- changing radio stations, fliipping around to different settings, stations, etc, all on its own- like it's possessed. this causes a distraction to the driver and is unsafe. its also really upsetting for this to happen on a card i've only had 3 years.

This vehicle has stalled out while driving at least 4-5 times since purchasing it in 2018, although issues started about 2020 or 2021. It usually starts with the radio console either malfunctioning or going dead completely while I’m driving and several minutes later (usually after stopping at a red light but sometimes while actively driving) the car stalls out in the middle of traffic. It starts up after few minutes but it’s a very dangerous situation. It also sometimes hesitates when putting my foot on the gas, as if there’s a fuel injection problem. I already got all the recalls fixed but there’s obviously other significant problems with this vehicle. If it causes me to get injured I will be taking legal action.

SRS Airbag light went off and ODB-II reader indicated passenger side supplemental restraint module error. We called Mazda October 20,2023 as the vehicle was nearing end of warranty period for the airbags system (warranty ended October 30, 2023). Mazda stated they could get the vehicle in on November 12, 2023, which is after warranty period and we would be required to pay to fix the car. An online search quickly resulted in seeing many other people with the same model of Mazda having the same issue for the passenger seat. I called national Mazda today, December 15, 2023 and they said that the vehicle is now 45 days out of warranty and no longer their problem.

Crack Cylinder Head less than 50,000 miles

The contact owns a 2018 Mazda CX-5. The contact stated that the vehicle was taken to the dealer for a scheduled service appointment. During the inspection, the contact was informed that the vehicle had a cracked cylinder and the cylinder head needed to be replaced. The vehicle was not repaired. The contact was informed that the repair would not be covered under the warranty due to the warranty being expired. The manufacturer was made aware of the failure. The failure mileage was approximately 84,000.

Two bolts simultaneously dislodged brake caliper which, in turn, disconnected brake fluid hose resulting in loss in brake responsiveness.

Defective cylinder head resulting in oil leak. Confirmed and inspected by dealer. No warning messages or symptoms. Just smell of burning oil.

I just had my vehicle in for routine maintenance and oil change and three days later it started leaking oil, staining my driveway, with the leak getting progressively worse then my check oil light went on, and the day I brought it in, and it was smoking under the hood. My safety and the safety of others on the road was at risk. At the routine maintenance visit they found no issues with the vehicle. After bringing it into the dealership they diagnosed it as a cylinder head crack needing replacement. We had another dealership look at the diagnostic video and explain that this is poor manufacturing. It’s just over 60,000 miles but is still within our warranty from a timeline aspect. Upon research we found this is happening to many people with a Mazda’s from year, 18 to 21. There are many forums about this. Upon an online search we found this problem documented as tsb SA-031/21. I am disappointed that the Mazda company is aware of the faulty cylinder heads in this vehicle, and now I am responsible for the maintenance charge.

Was driving at low speed and out of nowhere the warning lights came on , smart city , abs, among others. It's caused by this vehicles front facing camera and or front radar emblem malfunctioning causing the vehicle to slow down , low power , and steering wheel jerking making mechanical sounds. There's a tsb as well.

I own a Mazda that I purchased new in 2018. I have kept up with the maintenance to a “T”. I have never abused it. About a month ago I started smelling a strange smell. Like smoke or burnt oil. A couple of weeks later, the engine oil level light came on and the engine was low on oil and that’s when I started seeing that the motor was leaking oil, and I just found out that the engine head cylinder has a crack. I found out that these vehicles have a defect from the factory on this part that cracked, “Engine Head cylinder”. And now to repair it, it is going to cost me around $6,000. The warranty has run out.

Oil leak. Smoke from the engine. Inspected by the local body shop, we were told that the leakage would probably come from cylinder head. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I work for a body shop and we took this seat out in order to replace the frame underneath. While the seat was sitting on the ground, no one near it, the airbag deployed. We have it on video. We have concerns about replacing the seat/airbag if it's going to randomly deploy and potentially injure our technician or the customer. According to Mazda, there are no known recalls related to this and the customer is responsible for buying a new seat and airbag. I see online that other people have said this too, but they were driving the vehicle at the time it randomly deployed. I'm wondering if there are other complaints regarding this/a way for us to get Mazda to replace this since it seems like a part defect.

Had an slow oil leak. The cylinder head was cracked in my engine

Many incidents have occurred with this vehicle. First occurrence happened 11/25/21. Attempting to pass another vehicle and the car began slowing down and various warnings came on. Pulled off to the side of the road, turned off the vehicle and restarted without any further incident. This same thing happened 2 times in 12/2021 both time attempting to pass another vehicle. 2nd time in December the check engine light came on. Scheduled to be seen by a mechanic with the earliest appointment on 12/31/21. Mechanic recommended taking to a licensed Mazda mechanic. Appointment was on 01/07/22. They looked at the car and fixed the issue. Can't remember the issue at that time. By 05/2022, check engine light came back on and car would start slowing down and shutting off when attempting to pass another vehicle. If RPMs would go to high, car would do this. Check engine light came back on. Took to Mazda mechanic on 06/17/22. After several troubleshooting fixes, it was determined I needed a new engine as there were parts broken missing or broken. Did not have my car for 13 weeks. Most recently, on 08/13/23, car shut off in a drive through. Towed to mechanic and needed a new camshaft. Picked up my car on 08/21/23 and within 45 minutes, car shut off while driving up a hill. Towed back to mechanic. This time there are electical issues and an ill fiitting pin. Have to take it to a licensed Mazda mechanic. Having to tow it due to how unsafe it is to drive. Reached out to Mazda with my concerns ove

On 7/30/23, I was driving home from church, and was driving on the freeway in the fast lane when my 2018 Mazda Cx-5, that was only 5 years old, with only over 33.2K miles on it, started to stall. Thankfully, it didn't come to a complete stop, but slowed down tremendously, and had at least 5 malfunctioning lights come on all at once. The car wouldn't go over 25 miles afterwards. I was very thankful to make it home safely, but this was very alarming, since I never had any issues with that car, and always kept it very well maintained. For a car that was only 5 years old and had only 33.2K miles on it, to experience such a drastic problem, is very confusing. It was very concerning that the car almost came to a complete stop unexpectedly without any warning ahead of time, especially while driving in the fast lane on a freeway. I also took pictures of the malfunctioning lights that came on right after the incident took place. I had the car towed into the dealer the next day, and they told me that it was unusual that my engine would do that. They said that it needed a tune up earlier than expected. I was told that the 3rd cylinder was misfiring, and also when the engine isn't working properly, everything else in the car would shut down. Now, why would a car that's been very well maintained, with only 33.2k miles on it need a tune-up? And I always kept up with the oil changes on time. I found out that there was an engine recall on these particular models, but I was told by Mazda that

When I turn my car off I get ignition switch and it stalls then my engine come on and off

The contact owns a 2018 Mazda CX-5. The contact stated that while driving approximately 50-55 mph, the sunroof exploded without impact or warning. The sunroof shattered into several small pieces. The glass fell on the driver and she sustained injuries to her body and legs, but medical attention was not provided. The contact called the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was contacted, who referred her to the dealer. The failure mileage was approximately 26,000.

Cruise control suddenly ceased operating and I believe that is disabling the automatic collision avoidance system.

Infotainment system has begun exhibiting phenomenon described as "ghost touch" where options are selected randomly by the system due to touchscreen failure. This happens while the vehicle is moving and creates a significant distraction to the driver, creating a safety hazard for driver, passengers, and other cars on the road. This vehicle has not been inspected by a dealership but internet information indicates it is a known issue but a recall has not been issued from Mazda, which compromises the safety of the vehicle. No warning for incidents. This is an ongoing issue and occurs routinely during daily driving.
