Problem overview

Some Subaru BRZ owners report experiencing starting issues after displaying error signs while driving, with common underlying problems including a dead or weak battery, which can manifest as dim headlights and clicking sounds when attempting to start the engine. Additionally, some owners have encountered issues with a faulty alternator that fails to charge the battery adequately, leading to starting difficulties. Ignition problems, such as a lack of spark, have also been reported, preventing the engine from starting. Fuel delivery issues can cause the BRZ to crank without starting, while faults in the electrical system, like blown fuses or immobilizer errors, may hinder the vehicle's ability to start. Furthermore, some owners have faced problems with a broken starter motor, which can prevent proper engine cranking. It is advisable for owners experiencing these issues to seek inspection from a qualified mechanic to accurately diagnose and resolve the problem.
