Why is my Lexus UX 250h not starting?

Possible Reasons for Your Lexus UX 250h Not Starting
Based on the information from various sources, there are several potential reasons why your Lexus UX 250h may not be starting:
1. Dead Key Fob Battery or High Voltage Battery: One of the most common causes hindering the normal starting operation of the Lexus UX250h is a dead key fob battery. Additionally, a dead high voltage battery can also cause the vehicle not to start.
2. Clogged Fuel Filter, Blown Fuse, or Empty Gas Tank: Issues such as a clogged fuel filter, blown fuse, or an empty gas tank can also prevent the vehicle from starting.
3. Rodent Damage: Rodent damage, where animals crawl under the vehicle and bite through cables and wires, can affect various vehicle systems, including the fuel supply, oil supply, or power supply, and lead to the car not starting.
4. Electrical System Fault or Immobilizer Error: Any fault in the electrical system or an immobilizer error can also be a potential cause of the vehicle not starting.
5. Battery Issues: The battery being completely dead has been reported in a brand new 2022 UX 250H, where the car wouldn’t start even after boosting it. This resulted in a warning on the dashboard indicating a malfunctioning Tire Pressure Warning System (TPWS).
6. Sitting Idle for a Long Time: If the vehicle has been parked for an extended period, it may experience starting issues due to the battery not fully charging or being bad.
7. Blown Fuses After Battery Replacement: If the vehicle doesn’t turn on at all, it could be due to connected battery terminals backward or blown fuses, especially after replacing or disconnecting the battery.
It’s important to consider these potential causes and address them accordingly to resolve the issue with your Lexus UX 250h not starting. If the issue persists, seeking professional assistance from a Lexus service center or a trusted mechanic may be necessary.
