Engine Rattling And Whining Sounds problems of the 2013 Toyota Camry

The vvt camshaft gear is defective on many Toyotas this is common knowledge Toyota is aware of the problem has issued recalls on Lexus models only this could be dangerous causing engine failure mine has only 67000 miles is making the rattling noise.

On a cold start, the engine sounds rough for about a second or two. Grinding type noise. Completely different from the normal warm-engine start-up sounds. Also, the engine does not sound right for about the first mile or so after a cold start, sort of a whining noise from the front right side of the engine compartment. Clearly audible when lightly revving between 1500-2000 rpms. Although TSB-004-13-a has not yet been expanded to include the 2013 Camry, it sounds a lot like that exact issue may be affecting the 2013s. This 2013 was built in the same plant as the 2010-12 Camrys that are part of the TSB. I have taken it to the dealer twice and was told that 'these sounds are within the normal range of noises an engine can make'. I disagree. The vehicle now has 37k miles on it, I am hoping it will be fixed prior to the expiration of the powertrain warranty (60k).
