Thank you for allowing me to help you with all these questions. Let me take them one by one..
Does it matter if you buy a japanese Camry verses USA Camry?
Toyota does not import the Japanese made Camry anymore. It hasn't done that since 2011
Do they have the oil consumption issues?
The last years of the Camry that had oil consumption issues were the 2009 Camry and the 2011 Camry Hybrid.
Do they have acceleration and airbag issues?
No and Toyota doesn't use Takata airbags as of 2015.
Would you buy one?
No, I don't like them as I prefer a SUV but that's not what you meant. :)
If I were in the market then yes, I would not hesitate to buy a Camry but it would be the V6 as I like POWER!!!
Did they redesign the 2014-2016 engines so these issues won't continue?
The Camry was redesigned starting in 2012 and the new 2AR Engine came with it. The last 2AZ engine was used in the Camry is 2011.
How can you tell on the vin which cars have these issues?
See answers above.I am thinking of possibly getting a Camry XL or XLE from 2014-2016. (no V6 engine). How can you tell on a used vehicle that the issues are with this car before buying?
