The 2018 Tacoma fuel-system complaints split into distinct issues. A small group experienced real drivability failures: hesitation on acceleration, shaking, stalling without warning, and in one case loss of power steering during a stall event. These happened between 6,500 and 31,000 miles. One owner's fuel pump was replaced under recall 20V682000 at a dealer, but the symptoms did not go away.
The bulk of complaints—18 of 24—center on NHTSA recall campaign 20V012000 (Fuel System, Gasoline). Owners received recall notices but could not have the work done because dealers across the country—California, Ohio, New York, Georgia, Utah, Florida, Texas, Arizona, and New Jersey—all reported the required parts were not available. Many owners flagged that the manufacturer took longer than reasonable to supply parts; some manufacturer representatives confirmed parts were out of stock. One owner also reported RPM fluctuation at startup with an unknown warning light at 12,000 miles. Finally, one complaint involved a detached fuel-tank cover caused by corroded well nuts at 56,000 miles, which the owner did not repair.
