2.0/2.2 D-4D vs 2.5 / 3.0 D-4D (KD): which engine is more reliable?

According to our risk index, the 2.5 / 3.0 D-4D (KD) carries less risk than the 2.0/2.2 D-4D: 63/100 (high risk) versus 77/100 (very high risk). The 2.0/2.2 D-4D has 1 documented serious fault, the main one being «Warped cylinder head gasket and oil consumption on the 2.2 D-4D»; the 2.5 / 3.0 D-4D (KD) has 3 documented serious faults, the main one being «Cracked pistons in the 3.0 D-4D (1KD-FTV)».

Is the 2.0/2.2 D-4D reliable?

No: the 2.0/2.2 D-4D family is among the most problematic Toyota diesels. The 2.2 block (2AD-FTV and 2AD-FHV D-CAT) has a large number of cases of warped cylinder head gaskets and oil consumption or dilution in the Avensis, RAV4, Auris, Corolla Verso and Verso; the EGR valve and injectors fail frequently across the whole family, and the D-CAT filter clogs up if the car is not driven regularly on open roads.^[1][2][3][4]

Is the 2.5 / 3.0 D-4D (KD) reliable?

Toyota's KD diesels (2.5 D-4D, 2KD-FTV, and 3.0 D-4D, 1KD-FTV) have their best-documented weak points in the injectors: the copper seats of the 2004-2007 units, which can block the oil pickup, and the Denso injectors of the 3.0. The 3.0 of the Euro 4 era also has a record of cracked pistons; for the 2.5 we have only found the injector seal problem.^{[5][6][7][8][9]}
