2018 Mazda CX-9 Problems and Top Complaints – Is Your Car A Lemon?

Electrical, fuel system, vehicle structure and steering issues among the top complaints received by the NHTSA from vehicle owners


2018 Mazda CX-9

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 Electrical System

Electrical system issues can range from annoying to dangerous. No matter what level of problem is faced, it can be exhausting trying to figure out what’s wrong.

One such electrical system complaint comes from a customer left on the NHTSA website. “Driving the vehicle to an abrupt stop and I had no control. The dashboard lit up with all types of warnings and heat was coming from the front of the car.”

What’s worse than this is a Mazda recall that also affects customers. NHTSA Campaign Number 19V403000 states that the wiring harness connectors provide weak retention force, causing the passenger frontal air bag to not deploy during an accident. This issue can also cause inoperable turn signals, making it impossible for other drivers to know what’s going on, which only further leads to a higher instance of a crash that requires the air bags to work. It seems the automaker is hitting owners from every end with this malfunction. It’s just one way that Mazda wants to live up to its “never ordinary” reputation. Where most companies deal with a recall causing one problem, this defect causes countless problems.

Problems with the Fuel System

The fuel system ensures the engine has what it needs to move properly, but what happens when it becomes defective? Numerous problems can exist, from the inability to move at all, to complete lack of control over the engine power.

Here’s what one complaint left with the NHTSA had to say. “I was waiting in a stationary position, at a red light, behind some other vehicles, with my foot on the brake pedal. All of a sudden the vehicle started to lurch forward as if someone had stepped hard on the gas pedal! I was struggling to keep the car still by depressing the brake pedal harder, but it wouldn’t stop the car. I had to put it in Park and turn off the engine to stop the forward thrust of the vehicle.”

There’s another fuel system-related instance that the automaker owns up to. Service Bulletin #01-003-18-3421 states that some owners have trouble getting power out of the engine, but there aren’t any warning lights or DTCs. The cause is listed as a high fuel temperature, forcing the learned pressure to exceed a level that the PCM limits engine power to avoid fuel injection lack. To counteract this, technicians must upgrade the PCM control logic to allow for more power. Why the CX-9 wasn’t allowed to have access to this power from the get-go is anyone’s guess? That might have been too ordinary.

Problems with the Steering

When traveling with seven people, owners want complete control over the steering, but this is a major concern with the CX-9 models.

One Edmunds review says, “Above 65mph it has a vibration.  I went back and drove a GT and T model to see if it was a difference in tire size, but that wasn’t the case.  All three cars had the same thing to some degree.”

Other steering problems have also come to light. Service Bulletin #02-004-19-3574 states that customers are complaining about the steering wheel being more than three degrees off-center, even while driving on a flat, straight road. Technicians are told that up to three degrees is considered normal and should be left alone, while anything more than that can be repaired. Why did the steering wheels get put on off-center? Maybe to make the vehicle even more extraordinary in the eyes of the automaker.

Problems with the Vehicle Structure

One more aspect that helps to set it apart is the structure. It wasn’t built the way it should have been. It doesn’t take long to find countless complaints about the integrity of the vehicle.

Here is one Edmunds review that discusses the concerns. “Within four months there were numerous chips along the front of the vehicle. I have never had a vehicle chip s profusely in such a short period of time. Also do not have this chipping on our 2017 Mazda 6 which has standard paint. The paint just does not seem durable. When I took the vehicle in a six months for a service I pointed out the chips to the dealership service advisers. One service adviser even pointed out what he thought were a couple of paint imperfections.  But Mazda representatives said this was normal wear and tear and would do nothing to repair. If this is normal wear and tear on a vehicle that is not even a year old, then the upgraded paint is not worth the cost.”

There’s never a normal reason for a car’s paint to chip in less than a year. Any dealer that tries to state that is truth is simply covering its own butt. But, it turns out; the paint isn’t the only part that wasn’t manufactured correctly. Service Bulletin #09-018-19-3584 states that the door weatherstrip also comes off at the lower, front part of the rear doors. The automaker claims that it was caused by an insufficient gripping force applied by the factory. To correct this, the dealers have a newly shaped weatherstrip that should adhere better. Of course, Mazda will replace this weatherstrip, which only costs peanuts compared to a new paint job. When it comes to the more important and extravagant structure-related repairs that need to be made, it’s impossible to find the company stepping up to the plate. Once again, this only proves that the company is anything but ordinary, but it’s also likely that Mazda is losing valuable customers in the process.
