Problems with the Electrical System

Everyone wants to remain connected and entertained while driving, but the Mazda CX-5 electrical systems make that difficult.

Read this Edmunds review. “There is no way to easily switch through my favorited XM stations without taking my eyes off the road and going through multiple actions on the console control system. Oddly enough, there is a way to semi-easily flip through the 100+ other stations that I don’t listen to. Both the Mazda3 and the CX-30 have functionality on the volume knob that allows for switching through your favorites by pressing left or right, but when you pay more money for the CX-5, this isn’t included.”

This isn’t the only electrical system issue occurring with the Mazda vehicle. Service Bulletin #MT-003-20 also talks about an inoperative power liftgate, caused by the wrong amount of battery voltage. On the bright side, the company didn’t lie about the tagline. There is a difference that can be felt – coming from attempting to open the defective tailgate.

Problems with the Service Brakes

With how long brakes have been installed in vehicles, there’s no reason that this system should be defective. Yet, that’s what we see with this Mazda.

Read this NHTSA complaint. “We bought the car new off the Mazda dealership lot yesterday with 5 miles on the ODO. As my husband pulled off the lot, he smelled a burning small and the brakes felt like they’d seized up a bit. He pulled over and thought about turning back onto the lot, but then thought it may be just because they’re new brakes and continued on and drove home. This morning we remotely started the vehicle and the Mazda App sent us an alert that there is a critical vehicle malfunction having to do with the antilock brake system. The dealers are closed, so I don’t have any more info yet. I just signed back on to the app and there’s a second malfunction alert now with the emergency lane keeping. There are now currently 65 miles on the ODO. We have only driven the vehicle from the dealership home and parked it outside overnight.”

While the manufacturer hasn’t issued any statement about these types of problems, there are other bulletins about the brakes. Service Bulletin #04-005-20-3687a talks about a squeaking noise when the rear brakes are applied. It may even get louder when driving at slower speeds. The noise comes from poor contact made between the mounting support and guide plate. Again, it doesn’t take a rocket scientist to build an effective and reliable braking system. It’s not as if brakes are a new concept. Mazda needs to hire some engineers that understand the basics.

Problems with the Structure

Despite exceptional customer reviews back in the day, Mazda quality seems to have gone downhill recently. This is clearly seen when examining the defects in the structure.

Here’s another NHTSA complaint worth reading. “Red Soul on the CX5 having excessive paint chipping. Less than 5k miles on the car and have only had for 3 months and there’s already 9 to 10 chips on the hood and driver door.”

The paint issues go even deeper. Service Bulletin #09-004-21-3772 discusses how stains can appear on the vehicle, especially the trunk, roof and hood, after cold weather. This is caused by moisture that gets trapped between the RAPGARD and paint. The advanced fix is to heat it up with a heat gun or infrared drier. This communication is very clearly showing the level of quality that Mazda offers these days. However, it seems to have been going on for longer than people realize. Just recently, there was a class action lawsuit about some CX-5 models because the daytime running lights were defective and burning out prematurely. It looks like the newer models are going to have some issues worthy of lawsuits as well. In this regard, there’s no difference, as promised by the automaker. Nothing changes if nothing changes.
