Build my inspection planToyota Tacoma · frequently asked questions
Is the Toyota Tacoma reliable?
Yes — it's known for exceptional durability and resale, with only the transmission feel as a common complaint.
What's wrong with the Tacoma transmission?
The 6-speed auto can hunt between gears at low speed; it's a drivability quirk more than a reliability failure.
Should I check the frame?
Yes — inspect the frame for rust, especially on trucks from salt-belt states.
Why does the 3.5L V6 engine sound like it is ticking at idle?
The 3.5L 2GR-FKS engine uses Toyota's D-4S dual fuel injection system, which includes a high-pressure mechanical fuel pump. This pump produces a distinct, rapid ticking noise at idle. It is a normal characteristic of the engine and does not indicate a fault, provided the idle remains smooth and no warning lights are illuminated.
Do the rear leaf springs require replacement for heavy towing?
The factory rear leaf springs on this generation are known to be relatively soft and prone to sagging under sustained payloads or frequent towing. If a forecourt vehicle sits noticeably low at the rear or the bump stops show heavy impact marks, the springs may require upgrading or replacement before retail.
How quickly should the electronic four-wheel-drive system engage?
The electronic shift-on-the-fly four-wheel-drive system should engage within three to five seconds. If the dashboard indicator flashes continuously without engaging, the actuator is likely seized due to a lack of use. Advise your technicians to test the selector on a loose surface during the appraisal to ensure the transfer box operates correctly.
