Lexus CT200h intermittent starting issue with dashboard lights on when cold on Lexus CT200h

Some Lexus CT200h owners report experiencing intermittent starting issues, particularly when the engine is cold, with dashboard lights illuminating unexpectedly. These problems are often attributed to a dead battery, faulty starter, or a malfunctioning ignition switch, which can lead to difficulty starting the engine or intermittent power loss. Cold weather conditions can exacerbate these starting issues, especially if the vehicle has not been driven for an extended period, resulting in warning lights and system checks. Symptoms such as flickering instrumentation and difficulty starting after cold starts may indicate insufficient power, potentially due to a failing alternator. Additionally, some owners have reported experiencing vibration and knocking sounds during cold starts, possibly linked to oil starvation that resolves once proper lubrication is achieved. To mitigate these issues, it is advisable to have the battery, starter system, and alternator checked for faults, and to address any cold weather-related concerns promptly. If problems persist, consulting a professional for diagnostic services is recommended.
