Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) I need to bring our 2010 Prius back-in. The last time [xxx] with a "Y" worked on the rattle in the dash. He was able to fix that but now only in the cool mornings there is a popping sound coming from the dash. Please contact me as to when he can work on it again. It is very important that it be done first thing in the am. Car needs to be cool! I am sure if left in the sun it will not do it. If needed I can bring car in first to show problem and car can stay over night again if need. I know Toyota has a quality problem in this area, I will report it to Toyota mfg.& dot under other. Looks like other Prius have this same problem... [xxx]2010 Toyota Prius [xxx] color: Blizzard pearl selling dealer: [xxx]

Access to the oil drain plug and oil filter is through a plastic doorway opening under the engine compartment. The doorway is a partial cutout from a larger plastic shield which encompasses the entire front portion of the car. I performed my 3rd oil change and during this preparation I found that the door portion of the shield is broken away from the larger piece of plastic due to bending/hinging the door. Only after 2 oil changes this plastic door has broken off because the plastic is not designed to be repeatedly bent from open to close more than once. Unless you change your own oil, you will never see this door break off... and after 2 oil changes.
