The picture

Is the Mazda CX 9 or Honda Accord more reliable?

A plain-English read on what the NHTSA record says about living with each vehicle.

Mazda CX 9

The Mazda CX-9 is a three-row SUV that averages about 51 complaints per year over the past decade, with most issues centered on the engine. Owners frequently report a flashing check engine light that can lead to rattling sounds and power loss, often traced to internal engine problems like a failing water pump. Electrical glitches, such as false parking brake warnings, also appear. With 11 recalls and 22 crash-related complaints, it's a vehicle that demands attention to engine health and electrical quirks.

Honda Accord

The Honda Accord is a popular midsize sedan with a much higher complaint volume—about 444 per year—but that's partly because far more are on the road. The most common trouble spots are the engine, electrical system, and forward collision avoidance features. Owners describe sudden warnings for braking, lane-keeping, and adaptive cruise control, plus occasional engine noises and electrical failures. With 38 recalls and 160 crash-related complaints, it's a car with advanced tech that can sometimes malfunction.

What actually goes wrong

The problems owners report

The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.

What these mean
Engine

Owners report a flashing check engine light, often followed by a rattling noise and power loss. In some cases, the water pump fails and leaks coolant into the engine, which can cause serious damage if not addressed quickly.

Electrical System

Multiple owners have received false 'Critical Vehicle Malfunction' alerts, including parking brake errors, through the Mazda app. These glitches can be distracting and may indicate underlying sensor or software issues.

Power Train

Some drivers experience sudden vehicle shutdowns while driving, which is frightening especially with children in the car. A mechanic traced one case to a leaking water pump that caused coolant to enter the engine.

Service Brakes

Brake-related complaints appear, though fewer than engine issues. Owners may notice unusual brake behavior or warnings, so it's wise to have the braking system checked thoroughly.

We have a 2015 Mazda CX-9 Touring with All-Wheel Drive (AWD). The issue that has been happening is a flashing check engine light (CEL) indicator showing up in the gauge cluster. This issue originally started in October of 2023. I was on the highway doing at l…

What these mean
Engine

Owners report noises, loss of power, and multiple dashboard alarms (brake, hill descent, ABS) that can appear suddenly at highway speeds. These symptoms may point to sensor or software problems rather than mechanical failure.

Electrical System

Electrical gremlins include TPMS warnings that lead to tire failure, rodent damage to wiring harnesses, and other sensor faults. These issues can be intermittent and hard to diagnose.

Forward Collision Avoidance

Many complaints involve the adaptive cruise control, lane keeping assist, and automatic high beams showing error messages. The systems may shut off unexpectedly, reducing driver assistance when it's needed.

Service Brakes

Brake system complaints are common, often tied to the ABS or traction control. Owners may see warning lights or experience reduced braking performance, so a thorough brake inspection is essential.

Buyer analysis

Mazda CX 9 or Honda Accord: which should you buy?

The Mazda CX-9 has far fewer complaints per year (about 51) compared to the Honda Accord (about 444), but the Accord sells in much higher numbers, so the rate per vehicle may be closer. In practice, the CX-9's issues tend to cluster around the engine, while the Accord's are spread across engine, electrical, and driver-assist systems. The difference means you're more likely to face advanced-tech glitches in the Accord, but engine problems in the CX-9 can be more severe.

Recommendation. If you prioritize a simpler vehicle with fewer reported issues overall and can accept a higher risk of engine trouble, the Mazda CX-9 may suit you. If you need a sedan with widely available parts and service, and you're willing to deal with electronic quirks, the Honda Accord could be a better fit. Always have a pre-purchase inspection done by a mechanic familiar with the specific model.

Key differences

  • The Mazda CX-9 averages about 51 complaints per year, while the Honda Accord averages about 444—but the Accord is far more common on the road.
  • CX-9 owners most often report engine problems like flashing check engine lights and water pump failures; Accord owners report a broader mix including engine, electrical, and forward collision avoidance issues.
  • The Accord has 38 recalls versus 11 for the CX-9, covering items like hybrid software, spare tires, and brake control modules.
  • Crash-related complaints are higher for the Accord (160 vs 22), but this may reflect its larger sales volume rather than a higher risk per vehicle.
Watch on Mazda CX 9
  • Check for a flashing check engine light or stored engine codes, especially related to the water pump or coolant leaks.
  • Test all electrical functions, including the parking brake and any app-connected alerts, for false malfunction warnings.
Watch on Honda Accord
  • Scan for error messages related to adaptive cruise control, lane keeping assist, and automatic high beams, as these are commonly reported.
  • Inspect the wiring harness for rodent damage and check tire pressure monitoring system for accuracy, as failures have been reported.

Before you buy

  • Obtain a full vehicle history report and confirm all recalls have been performed.
  • Have a trusted mechanic perform a pre-purchase inspection, focusing on the engine, transmission, and electrical systems.
  • Test drive the vehicle at highway speeds to check for sudden warnings or power loss.
  • For the CX-9, specifically ask about water pump service history; for the Accord, check for software updates to driver-assist systems.
  • Verify that all safety features (brakes, airbags, backup camera) are functioning correctly.
