User Complaints and Problems for the 2018 Mazda CX-5

Mechanical Problems

  • Engine jack of all troubles -. The most common complaint seems to revolve around the engine. The engine has failed for multiple users due to an oil leak due to a defective head gasket and or a cylinder. Subsequently, the oil leaks have also caused the vehicle to release “white smoke” from the engine bay, causing great distress to the occupants. Various users have also stated that the engine has stalled on them, many dealerships and owners stated that this was due to the “fuel pump defective”. Mazda is aware of this situation and has already made recalls to the affected models, you can refer to NHTSA ID: 21V875000 & 19V497000 for more details.
  • Brakes failure -. Multiple users have stated that the vehicle’s brake tends to fail on them or act on time to stop the vehicle on time. So far no major injuries have been reported. One dealership provided a reason that the brake calipers had prematurely worn out.
  • Fuel system recalls - This seems to be a persistent problem, hence the multiple complaints registered solely on this matter. On the matter of “fuel pump failure” recalls made by Mazda, the dealership seems to take an unreasonable amount of time to fix it, due to a delay in getting the necessary parts from the manufacturer. This is in relation to the Mazda recall referring to the NHTSA ID: 21V875000.
  • Powertrain being unreliable mid-operation - Users have stated over and over again that the vehicle’s powertrain would tend to stop abruptly mid-operation without any warning and come back momentarily. Even more bizarre, multiple users have stated that the vehicle would accelerate on its own, without the user depressing the accelerator. Mazda is already aware of this situation, as this is happening due to a software malfunction in their powertrain control moduleand has made recalls. You can refer to the NHTSA ID: 19V497000 for more details.
  • Suspension is leaking oil as well - Multiple users have stated that the rear shocks were leaking oil and had to be replaced.

Electrical Problems

  • Accelerator not responding to the user’s instruction- Various complaints have been registered against the accelerator for failing to comply with the user’s instructions when they depress the accelerator and subsequently stalling.

Safety problem

  • Airbags failure- Failure of the airbags either through warning lights or prematurely being deployed on the slightest contact has caused some distress to the users. 

Exterior Problems

  • Paint chipping off on the vehicle with Soul Crystal Red paint- Users with that particular paint have registered complaints that the paint was chipping off from their vehicle, especially from the sides and the hood. A professional opinion is that the method and material of paint used is the reason behind this happening.

Should you buy the 2018 Mazda CX-5

The 2018 Mazda CX-5 has problems, there is no question about it, but so do most vehicles. Considering the Mazda SUV has a 4-star overall rating from the NHTSA, and only 3 recalls made, the vehicle is relatively safe. Just as a precaution, ensure that your 2018 Mazda CX-5 has been checked for the recalls made for this model year, and ensure that your engine cylinders are solid. and the powertrain is working smoothly. We highly recommend you to stay away from “ Soul Crystal Red” painted vehicles, so as to make your life easier. Also, make sure your 2018 Mazda CX-5 oil problems are resolved within the dealership before the full purchase since it is a hassle to do so afterward. The 2018 Hyundai Tucson would be the second-best choice, with fewer complaints and recalls made against the Hyundai SUV.
