Proton Waja Premium or 1.6X has all the extra luxuries compare to the so called basic spec Waja. that includes auto climate control, ABS, Traction Control, Front Airbag, Rear adjustable Headrest and rear Central Armrest among others. Proton stopped production of 1.6X after they launched Waja 1.8 due similar pricing. Waja 1.8X has more kit, but there is also a lesser spec minus few things. normally, they comes in white colour and recognisable with their large 16" wheels.
Waja EV has similar equipment as Waja 1.6X except for unique 16" alloys, new beige colour interior and new instrument meter design.
as for the recent recall, that involves all Waja EV ONLY, which has chassis number from PL1CF1SNR4F192489 to PL1CF1SRR5F217757, assembled from June 2004 to January 2005.
all Wajas involved are required to come for free inspection on the alloy wheels, which are suspected to suffer from weak construction during manufacturing.
Replacement if required necessary will be covered under warranty and no charges at all to the owner.
the problem roots from supplier and not from Proton itself. :D
