Lexus Repair Questions? Ask a Mechanic for Answers ASAP
Hello, I am Jose Sebastian. Your automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.
Dear customer, start by checking the condition of the battery if your battery has more than 2 years of use it is likely that it has reached the end of its duty cycle when these lexus have low voltage this type of electrical problem can occur because the lack of electrical voltage deprograms the electronic systems.
The second thing I recommend is to check what is happening in the fuses under the dashboard and under the engine compartment as it is possible that I feel fuse have been burned by an electrical problem.
Finally if all this is correct it is recommended to perform a computer diagnostic to check if there are error codes that are causing this and also to do a factory data reset to rule out a problem of deprogramming in the electronic system of your Lexus.
