Fuel System Issues (Pump & Gauge)

Recalls indicate potential defects with the fuel pump, leading to insufficient fuel supply or over-pressurization. Additionally, a software error in the instrument cluster can cause inaccurate fuel gauge readings, potentially leading to unexpected fuel depletion. Estimated repair cost: $400 - $1,200.

HECU Module Fire Risk

A critical recall addresses a fire risk associated with the HECU (Hybrid Electronic Control Unit) module. The remedy involves installing a fuse kit. Estimated repair cost: $100 - $300 (Fuse Kit Installation).
