2018 MAZDA CX-5 Complaints

This car that I financed on [XXX] 2024 has been back to the dealership over 6 times. My car loses power on the freeway and all main roads. I push the gas pedal and nothing happens so I am forced to pull over and turn the car off and restart it again. It's very dangerous when I'm merging on the freeway and I cannot accelerate and have to pull over in traffic. Sports cars International in Lynnwood Washington is well aware of the issues I've been having and they have not fixed them. They have allowed me to drive off the lot knowing I am in a car that is dangerous and unsafe, a car that could kill another family or myself. They are unresponsive to call of my phone calls and emails. This car has had nothing but problems since then day I drove it of the lot. Come to find out from their Yelp and BBB reviews thus happens to a lot of people that buy cars from them. They are rude to me and I feel like I'm on danger every time I drive this car.

To Whom It May Concern, I am writing to report a serious issue with the 2018 Mazda CX-5, specifically regarding the structural integrity of the cylinder head. This defect leads to significant oil leakage, toxic smoke entering the vehicle, and substantial repair costs for owners. Despite these problems, it appears Mazda has not initiated a recall, despite being aware of the issue. My wife owns a 2018 Mazda CX-5 with approximately 80,000-90,000 miles. Recently, after she returned home from work, we noticed gray, billowing smoke emanating from the hood. The smell of burning oil and rubber permeated our garage and home, making it difficult to breathe. We took the car to an independent technician at AAMCO, who, after a thorough evaluation, concluded that the cylinder head was cracked. Given the car's mileage and overall condition, they were extremely surprised and double-checked all other possibilities before reaching this conclusion. They informed us that this issue seems widespread, as evidenced by their online research (links provided below). For further verification, I drove the car to a Mazda dealership, which took about an hour due to avoiding the highway. During the drive, I continuously smelled burning oil, which raises significant health concerns, especially for my pregnant wife. The dealership acknowledged that this issue occurs with the CX-5 and quoted us $5,350 before tax for repairs. While my wife and I are fortunate enough to afford this repair, many consumers may not have $5,500 readily available to fix a manufacturing defect. This situation underscores the urgent need for Mazda to address this problem through a recall.

The contact owns a 2018 Mazda CX-5. The contact stated that while driving at an undisclosed speed, the vehicle independently decelerated and lost motive power. The check engine warning light illuminated, and the vehicle stalled. The contact attempted to restart the vehicle; however, the vehicle failed to restart. The vehicle was towed to an independent mechanic and was diagnosed with fuel pump failure. The contact was informed that the fuel pump needed to be replaced. The vehicle was not repaired. The contact was advised to have the vehicle towed to the dealer. The vehicle was towed to the dealer where it was diagnosed with fuel pump failure and fuel pump rail failure. The contact was informed that the fuel pump and the fuel rail needed to be replaced. The vehicle was not repaired. The contact was informed of NHTSA Campaign Number: 21V875000 (Fuel system, Gasoline) however the VIN was not included in the recall. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 62,000.

For the past year my car has been in and out of the Mazda dealership. There is a red key with an explanation point through it that was been coming up once I am in the car and someone else opens a door then it stays flashing the whole time I'm driving. My trunk has been having issues too with not opening like it should and when I'm driving then I go to turn it starts beeping. The dealership keeps telling me they can't replicate the problems and keep giving me the car back. I have only had this car for two years. I love my Mazda but it's sad I have no other options at this point.

The cylinder head cracked and broke resulting in a massive oil leak that covered all the parts under my car and under the hood and engine which in result started to smoke. This is not only a major issue of extremely costly repairs but more importantly also serves as a major safety issue. This could had caused fire to the vehicle and also engine misfire resulting in engine failure while in drive and potentially lead to critical injury or death for me and my family. Mazda was aware of their poorly designed engineering for this critical and extremely important component and it is known Mazda recognized the issue by issuing a TSB. After further research there are numerous TSB issued for multiple engine failures with Mazda. It is also known that certain VIN number vehicles manufactured with this defect are commonly reported and have experienced this exact same issue within only a few years and or very low mileage. This is a major mechanical failure to happen to vehicles within a short time span of purchase and results in loss of customer trust and loyalty. As a first time car buyer I am deeply dissatisfied and disappointed with Mazda. I would not had purchased a brand new car if I would had known I would experience this only at 5 years and 71 thousand miles. My vehicle was inspected and diagnosed by a certified Mazda dealership. I was advised and informed that this is a huge issue that has happened with all customers. Mazda knowingly neglected the proper manufacturing and engineering for the cylinder head and other engine parts, which is the most critical component to any vehicle to function and operate. Lastly what is more concerning was that there was no warning signs such as lights or sensors that were triggered as warning of the issue and vehicle failure posing as another safety concern for drivers.

Cracked cylinder head. Burning oil smell. Coolant leaking into oil. Car purchased a year ago for $21,500. Dealer I bought it from paid 1/2 after sending it out to Mazda to be diagnosed and fixed.

The contact owns a 2018 Mazda CX-5. The contact stated that while her son was driving at approximately 45 MPH, the check engine warning light was illuminated. The contact also stated that the vehicle lost motive power and stalled. The vehicle was able to be restarted. The vehicle was taken to an independent mechanic where it was diagnosed that the fuel pump and fuel rail needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 75,896.

Multiple instances of phantom braking, which resulted in two instances where we were just inches from being rear-ended. The circumstances of the phantom braking are similar, and has occured many times. CIRCUMSTANCES OF PHANTOM BRAKING are as follows: vehicle in front in lane makes right hand turn from lane (with or without turn signal or braking). The vehicle in front typically has exited the lane, and the Mazda emergency brakes hard! Variable vehicle acceleration/deceleration dynamics factors: the Mazda could be coasting, decelerating with brake litely applied, accelerating in lane (because vehicle has fully exited lane), accelerating and exiting lane (go around turning vehicle). Variable turning vehicle rear lights (signals, brake lights) factors: the turning vehicles can be braking or not, turning with or without signaling- it does not matter. The Mazda will brake hard regardless. This may be an extension of the same: when traveling on an Interstate Highway, nominally at the posted speed. When a faster vehicle safely accelerates into the Mazda’s lane, the Mazda will brake hard. The Mazda does not recognize that the vehicle entering the Mazda lane is accelerating, nor does the Mazda seem to understand (anthropomorphism) the context (dynamics) of the situation (accelerating merging traffic). Hard braking in these circumstances has resulted in several near misses being rear-ended. The request for DATE below should be “NA”, because the phantom braking has happened many times.

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 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
