I believe the Colorado oil use issue is from a batch manufactured in a 4 month period in 2014. The test is, if the engine uses 3 litres of oil in 10,000km, they renew the engine. Some of these motors are stopping the excess oil use at around 70,000km, strangely. In my small rural district, I know of three. One getting a new engine, two undergoing the oil use monitoring. Unbelieveably, Holden's initial response to the issue was to replace the oil dip stick with a longer one!!!!!!!! True! From the horse's mouth. Astounding.
I suspect a LOT of 2014 Navaras will be up for sale in 2017, as they run out of warranty. Beware.
The issue with the Ranger is the manual gearboxes are not holding up as well as they should. The auto trans Rangers are fine (info direct from a fleet owner).
Navara owners are reporting several cases of issues with the manual gearboxes. Which means poor motor, trans, and diff. Sad news, for a firm that built legends like the LD28, the TD42, TD27, QD32 etc , with strong drivetrains (generally).
Bear in mind that many of the modern diesel utes are putting out 450-550Nm of torque, and are rated to pull 3-3.5 Ton, so any drivetrain weakness is being exposed much more quickly than in days gone by. To put this torque in perspective, an intercooled 3.0 litre Surf diesel is rated at around 340Nm, a nissan TD42 (4.2 litre diesel) turbo is rated at 330NM, and a Toyota 1UZ (4 litre V8 petrol) at 350Nm.
