Problem overview

Some Acura MDX owners report experiencing issues where the vehicle starts but won't stay running, often attributed to faulty starters, ignition system problems, or fuel system issues. Additionally, symptoms of a dead battery, such as slow engine cranking and dim interior lights, have been noted by some owners. Furthermore, several Acura MDX owners have reported problems with inoperable power windows, which may stem from electrical system malfunctions or wiring harness issues affecting multiple components, including the gas door and rear hatch. Lastly, some owners face difficulties with the gas cap not opening, potentially due to a loose or damaged cap, which is crucial for sealing the fuel system and maintaining pressure. Addressing these concerns may require troubleshooting and repairs, and it is advisable for owners to consult a professional mechanic or Acura dealership if issues persist.
