Toyota simply has too many SUV type products, both globally and in the US. Just off the top of my head:
RAV4- just renewed, sells well & will continue.
Venza- costs more than the Highlander, and although its a nice vehicle, it has failed to meet sales targets. It will quietly disappear.
RX- Practically pioneered the segement. The market is much more crowded with really good compeditors today.
Fortuner- Is based on the (Hilux) N70 platform, which is due for replacement, along with the 120 based Tacoma. Since both are supposed to share architecture, I can't see the Fortuner continuing as a completely seperate model.
FJC- started life on the 120 group, but has been partially migrated ofer to 150. Either way, the chassis is obsolete. CAFE will put the final nail in the coffin, as it cannot continue as is. There is no business case to redo it (sadly)
4Runner- one of the oldest name plates in the segment, and one of the last to still use serious hard parts. It has the same challenges as the FJC, especially since it competes directly with the LC150 where its sold outside the US and Canada.
LC150/Prado/GX- will continue through its model cycle. Same goes for anything else named Land Cruiser. Since its already federalized as the GX, perhaps we could get an Africa spec version for Toyota.
Highlander- just renewed, sells well & will continue.
LC200/LX570- I would be surprised if the LC200 continues in the US much longer. Canada already gets by with just the LX570.
Sequoia- If it weren't for moderate Middle East sales of these, it would already be gone. For now it will continue as long as the current Tundra.
The FJC was US market only until recently, and still offers only the 1GR for power- that makes it unattractive in much of the world. The price has crept up steadily. While you get what you pay for, I would love to see Toyota do something that actually starts in the low 20's and can be had truly stripped.
I've heard a while ago from a friend on the inside that the 4Runner might not get renewed.
