Hi, I just bought a used lease end 2014 GS 350 f sport. When I test drove it and started the car it trembled a little bit and stopped soon after and I figured since its super hot the ac was the cause and ignored it. So I then come home after purchase and notice that it sometimes still does this right after I start the engine... (Ac not on) Is this normal? Should I be concerned? Thnx!

 

How many miles on the car take it in for oil change/service and let the dealer inspect the car under warranty that's what I did.

 

It has 44k miles... Higher than average but I drive less than average so I figured no big deal. I plan to take it in for the 45k service but am worried they'll try to up sell service since I'm a girl... Wanted to see if anyone has this issue and knows what it is so I don't get bs'd or tricked into stuff I don't need. Which warranty would this fall under? Cuz if basic warranty, it's over the mileage for that...

 

Car has 4 years 50k miles warranty from the date of first vehicle use according to Lexus books. You should be just fine. I have posted the 45k miles service details.

 

It's probably OK, in my experience a car usually does that if the air intake system such as the throttle body probably needs cleaning. I suspect a low grade fuel was used at all times. This could be premature but the spark plugs might be dirty. In the past I would use fuel system cleaner and it work for a little while until I did a full tune up replacing all dirty/worn parts even when they are way before the required replacement interval.

 

^ as LXGXSAM1 said, also I always laugh when I see your signature, the "LOL!" to the leaf =P.

 

Thanks for the input guys! I feel more at ease now. Jus gonna wait for my 45k mile service

 

@Mimix714 -
Any loss of power when the car was trembling? Any warning or check engine lights flashing in your dash?
I'd bring it in for service, get the codes checked.
Sounds like misfiring, you may need new spark plugs. Check your transmission fluid, also.

 

None of the above, just would tremble shortly like an older car when you turn AC on n it stops within 10 seconds. It hasn't done it recently so I'm not too concerned for now. I will request to get inspected when I get my 45k service. Thnx!
