Three-row SUVs are the latest rage for family travel, and the 2018 Mazda CX-9 is one of the top choices. The newest lineup claims that it’s “never ordinary,” and owners couldn’t agree more, especially since the majority of vehicles aren’t dealing with a faulty electrical system, defective fuel system, a malfunctioning steering system or shoddy structure, as this one is.

Problems with the Suspension
The car suspension consists of many components, including shock absorbers, springs, tires and linkages to ensure a smooth and safe ride. However, the CX-9 has some faults that must be addressed.
One NHTSA complaint states, “The contact owns a 2019 Mazda CX-9. While driving in Reverse in order to parallel park the vehicle, the front axle fractured and caused the front driver’s side tire to bend inwardly. The vehicle was towed to [dealership] where it was diagnosed that the tie rod failed and needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and provided [case number]. The approximate failure mileage was 10,600.”
It turns out there are larger problems that must also be discussed. NHTSA Campaign Number 19V77000 discusses a defect to the tires that allows the tread to detach and separate. If this happens, customers could experience an unexpected blowout, leading to a serious accident. The problem stems from the automaker using the wrong rubber compound on the tires. One thing is true so far – this SUV is not “ordinary.”
Problems with the Electrical System
Whether it is used to run Bluetooth or to keep the engine operating efficiently, the electrical system plays a part in every component of the vehicle. Yet, the CX-9 showcases a dud of a system.
Here is one Edmunds review discussing some issues. “But the biggest complaint I have is with the Mobile Start app. It sucks. No other way to say it. It has extremely limited functionality. Most annoying though is that you have to both login and enter the PIN to operate it. No facial recognition? This is especially unforgivable because you pay extra to have it installed and on top of that there is a $65 annual subscription fee.”
There is an even larger electrical-system problem. Service Bulletin #SA-049-20 discusses how a battery parasitic draw might prevent the engine from starting. However, there is no solution to the problem. Instead, the automaker only states that it is “aware of the issue and is working on a solution.” In the meantime, many people are heading out to the garage to get to work on time and finding themselves in a difficult predicament. Hopefully, their bosses won’t fire them for someone more “ordinary.”
Problems with the Transmission
Looking at the powertrain, we see the same level of defects as with the other systems.
Here is another Edmunds review, this time related to the transmission. “6 speed tranny is fine for driving around town but lacks on hwy…RPMs are way too high at 75-80 making for more noise and killing fuel economy.”
Mazda isn’t attempting to hide any issues. Service Bulletin #05-003-20-3725 discusses a Check Engine Light and Transaxle Warning Light that could be caused by a defective oil pressure switch. It turns out that this switch can get stuck because of contamination in the passage. To fix the problem, Mazda issues some changes to reduce contamination and improve engine logic. However, by the time that the issues are fixed, many customers have already dumped the SUV for something more “ordinary.”

| Description | 2019 mazda cx-9 gt infotainment screen is spidering / cracking in the upper right-hand corner making it difficult to see information on the screen. This appears to be an ongoing problem with the design / components of the infotainment screen. I note a may 2020 tsb / dealer notification campaign which extended the warranty coverage period to 7 years for this exact same issue in 2016-2017 model year cx-9s. The 2019 model year cars have the exact same problem and mazda is not covering the issue. |

| Description | Hi, I have a 2019 mazda cx-9. It is a certified pre-owned vehicle we purchased in october 2020. Upon going out to our car yesterday, june 12th, 20212, I noticed that the top left of the center console screen appeared to be damaged. I was perplexed because the car was locked and it wasn't there previously. As I touched the screen, I realized that cracks/peeling were all internal within the screen. I immediately decided to google the issue to see if others have had similar experiences, and I found dozens and dozens of examples. Separately, there is a safety alert on the issue from mazda (see here: https://static. Nhtsa. Gov/odi/tsbs/2018/mc-10134920-9999. Pdf). Additionally, the issue has gotten so bad that mazda has issued a warranty extension for this specific problem (see here: https://static. Nhtsa. Gov/odi/tsbs/2020/mc-10176061-0001. Pdf). The extension only is covering cars made through 4/29/17, and ours was made after that so is not formally covered at the moment. I called mazda customer service, where both my cars are formally registered, to discuss the issue. They told me the best they could offer was for me to take it to a dealer, have the dealer attempt to have it covered under warranty, and mazda corporate warranty will respond, but their response is final. If they say it's not covered, there is no debating it. As you can see from the picture, this is the exact issue that is currently being covered free of charge in earlier models. A recall should be issued or mazda should be directed to expand this to later models since this is clearly not limited to the years they currently have listed. See the picture attached and the links above. Thank you |

| Description | The front end especially on the drivers side front suspension. The noise seems to be coming from the control arms and ball joints area. I have reported this to the dealership many times since purchasing the vehicle new. They continue to say that there is no issue but the noise is not going away. I believe it is associated with this tsb but no recall has been made. I am very concerned as the steering feels looser than usual and may cause an accident. Tsb 10170655 - description some vehicles may exhibit one or more of the following noises from the front suspension: 1. A creaking noise from under the front of the vehicle (front lower arm bushing) when driving over bumps at approximate 12 - 25 mph (20 - 40 km/h). The noise occurs when the road surface is wet or after the vehicle has been washed. The noise becomes more noticeable as the bumps get higher. The creaking noise is caused by the front lower arm bushing (a) making a stick-slip noise during wet road conditions. 2. A clunking noise from the front coil spring when driving over bumps. The clunking noise is due to stick- slip between the front strut bearing (b) and the coil spring (c). 3. A popping noise from the bump stopper (d) when driving through gutters. |
