How the 2026 compares with nearby years
Against the 2025 Trax: the two manuals do not print the same part types, so there is nothing to compare line by line.
The 2026 Trax belongs to the 2nd gen, which began with the 2024 model year (No MY2023 in US; MY2027 refresh unveiled Oct 2026); generation dates. Parts often carry over within a generation, but the manual for your exact model year is the one to trust.
Shared with other 2026 models
- W16W (back up lamps): 7 other 2026 models list it, including Kia Carnival, Kia K5, Kia Niro, Kia Seltos, Kia Sorento, Nissan Pathfinder.
- WY28/8W (front turn signal/parking lamps): no other 2026 model this site has read lists it.
- W21W (tail/stop/turn): 2 other 2026 models list it, including Nissan Altima, Nissan Rogue.
A shared number means the same replacement part fits both cars, so one spare can cover two cars in the household.
What the manual does not print
The 2026 Chevrolet Trax owner's manual does not list wipers, battery, filters and oil sizes; for the battery, read the label on the battery fitted to the car, then check the size against the BCI group chart; for wipers, measure each blade end to end and buy the nearest whole-inch size.
Buying the parts for a 2026 Trax
- Small bulbs: this manual names 3 replaceable bulb positions. Wedge bulbs such as W5W and 194 differ from twist-socket bulbs such as 7443 or 3157, so match the full number, including suffixes like NA (amber).
