Acura MDX Won’t Start Clicking Noise

Problem 1: Dead Battery

Dead Battery

A dead battery is one of the most common causes because when you try to start it, it does not provide enough power, and vehicles produce a clicking noise but cannot start. You should check for the battery to ensure it is working okay to start the vehicle.


  • Open the hood and find the battery near the engine compartment.
  • Remove the battery covers and disconnect the cables, first the negative cable and then the positive cable.
  • Remove the battery and clean its terminals
  • Connect the battery with a Multimeter to check its voltage; it should be 12 volts. If it is less, recharge it for a few minutes and then recheck. If it is still low, replace it with a new battery. I recommend the ML7-12 – 12 VOLT 7.2 AH SLA BATTERY. It is affordable and performs excellently in a variety of conditions.
  • Install the new battery and test to ensure there is no clicking sound and the vehicle starts properly.

Problem 2: Faulty Starter

Faulty Starter

A faulty starter supplies consistent power to the ignition switch to turn on. When it has a fault, it fails to supply power; ultimately, you hear the clicking noise, but MDX won’t start. Check for the starter and fix it if needed.


  • Wear gloves and park the MDX on a safe and level surface. Once parked, engage the brakes for safety. Also, disconnect the cables from the battery.
  • Locate the starter on the driver’s side under the vehicle. It will be near the transmission.
  • Raise the vehicle on a secure jack stand. I recommend Jack Boss Car Jack Stands 3 Ton Capacity. It offers support for all heavy vehicles.
  • Access the starter and disconnect all the wires connected to it.
  • Remove all mounting bolts and remove the starter. Check it for damage; if it is, you will need a similar one.
  • Install the new starter and secure it with bolts.
  • Reconnect all wires and lower the vehicle from Jack’s stand.
  • Attach the battery and try to start the vehicle to ensure the problem has been solved.

Problem 3: Faulty Ignition Switch

Faulty Ignition Switch

A faulty ignition switch may cause a clicking noise when starting your Acura MDX. It prevents the power from reaching the starter, and you only hear the clicking sound. You must check for the ignition switch and fix it or replace it as needed.


  • Switch off the vehicle and disconnect the battery for safety
  • Then remove the panels around the steering columns to access the ignition switch
  • Detach all the electrical connectors and remove the mounting bolt to access the ignition switch
  • Thoroughly check the ignition switch, and if possible, repair it; otherwise, replace it.
  • Mount the new ignition switch and put back all the items you removed
  • Once done, connect the battery and test and ensure Acura Mdx is starting properly

You may have issues with alternators that fail to recharge the battery properly. So, a weak or dead battery may cause an Acura mdx starting issue. You should check for the alternator; if it has faults, you must replace it to ensure proper battery recharging.


  • Locate the alternator on the passenger side near the front of your Acura Mdx engine
  • Then disconnect the battery for safety
  • Now loosen the belt tensioner, slide off the belt from the pulley, and remove it
  • Then disconnect all the electrical connections
  • Now you can access the alternator, unbolt it, and remove it. Check it thoroughly, and replace it with a new one if damaged. 
  • Reconnect the wires and belt, and then the battery
  • Now test it and ensure the issue is removed
  • You can also confirm it by checking the battery voltage with a multimeter. You can use any of the digital multimeters for accurate reading.

Problem 5: Faulty Fuel Pump

A broken or leaked fuel pump may prevent your Acura Mdx from starting. It fails to supply proper fuel to the engine, which cannot generate the spark needed to start the vehicle. You must check for the fuel pump and replace it if needed.


  • Wear safety gadgets such as masks and gloves, and park the vehicle in a ventilated area
  • Then locate the fuel pump, check it lift the rear seat 
  • Once located, remove its panel to release pressure on the fuel pump 
  • Inspect the fuel pump. If it leaks, try to fix it; otherwise, replace it. 

I recommend the Vphix Gas Fuel Pump Module Assembly for the Acura MDX. It is compatible with all models of the Acura MDX.
