Gs 450h Check Hybrid System glitch?

[Savedline]

Hi everyone, I bought a 2008 Lexus GS450h from a guy who owns the car for years, I took the car with no light on dashboard or problem, after driving for like 15 miles check system engine red triangle light came on, on the way home, I called the guy and he told me to continue driving and later check the tyre pressure and that it should be fine. I have checked the tyre pressure which was not even on the tyres, one was 28,32,37 and 30, I inflated all the 4 tyres for 35psi and still the light is on.. Any idea what I can do to correct it as I have plan to have it checked..

I am looking for more information on this GS450h 'Check Hybrid System' 'Check VSC' and 'Check ECB dash warning 

I am a loyal Lexus owner my first car a used GS300 with no problems, my second cars my beloved LS430 no problems until A66 potholes wrecked my suspension 

I now own my used GS450h which has been trouble free for the last last few years But I am now getting the 'Ping' with error message 'Check Hybrid System' Check VSC' and 'Check ECB' with flashing amber traction control light Flashing red triangle, orange brake warning also orange engine management warning light

Occasionally warnings change to Steady red warning light and Steady 'Check Hybrid System' no other warnings 

I have had my car into my local reputable garage, the diagnostics indicated a faulty rear nearside ABS sensor, which reading other posts was plausible, they suggested fitting ABS/Speed sensor also nearside rear wheel bearing at a cost of around £400 I was given the option of sourcing parts myself but could not find them available at a cheaper price And approved the work I was then told The 12 volt Battery was failing and (please don't hit me)  I agreed to replacing Battery as new spec at £250

My car ran OK for a week or so then the same faults were thrown in after a trip to Yorkshire, I took my car back to the garage, more diagnostics and historical Battery faults were cleared All has been good for the last three weeks Now I have the same problem 

My worry is my Lexus GS450h going to be a money pit I'm seriously thinking of going back to Vauxhall after twenty years of happy Lexus driving

Hi, I have the check hybrid light on and know exactly what my problem is, the wires behind the engine have melted because of a rodent and I get the error but when scanned it says "engine failed to start" thats the reason for the hybrid warning as the regular battery in boot was not being charged due the engine not starting. Hope this helps some people. cheers
