As of early 2026, renting a car in Hawaii remains extremely expensive, with rates in popular hubs like Maui (OGG) and Honolulu (HNL) often reaching "shocking" levels. Recent data indicates that the average weekly rental for a standard sedan can exceed $800 to $1,400, representing a 30% to 50% increase compared to 2025. This price surge is driven by a combination of factors: high demand from a booming post-pandemic tourism market, a limited supply of vehicles due to island logistics, and the high cost of maintenance and fuel in the Pacific. Furthermore, many rental companies have shifted their fleets toward electric vehicles (EVs) to comply with state environmental goals, which, while sustainable, has led to higher base rental prices. To avoid these costs, travelers in 2026 are encouraged to book at least 3 to 6 months in advance or utilize car-sharing apps like Turo, which often offer more competitive rates. Without an advance reservation, "walk-up" prices for a Jeep or SUV can easily climb past $250 per day, making the car rental often the most expensive component of a Hawaiian vacation.
