For most first trips the answer is yes, and it is not close. The things people come to Maui for are spread along two coasts and up a mountain.
Budget for a car on any day that leaves the resort. Drive times and traffic windows are in our getting around Maui guide.

Whole days without a car are realistic in two places, and nowhere else.
Wailea and Kāʻanapali both support a full day on foot: beach, pool, lunch and dinner without moving the car. Some hotels run a local shuttle on top of that. A guided Road to Hāna tour, a whale watch with hotel pickup or any organised excursion also removes the car from that day entirely.
Count the days that leave the resort, not the nights you sleep on the island.
On a seven-night trip with two resort days and one guided tour day, that is four days of car, not seven. Renting for selected days is the honest budget strategy, and it works best when you front-load the exploring and leave the resort days at the end.
Book early in peak periods either way. Maui runs out of cars before it runs out of visitors.
A compact car or a midsize crossover covers almost every Maui trip.
Smaller is better on the Hāna Highway and in beach parking lots, and it is easier to live with on the narrow stretches where two cars have to negotiate. Pick for the parking, not the photograph.

You do not need a Jeep for the Road to Hāna, and four-wheel drive is not required for the standard route. A large SUV is usually more annoying than helpful: harder to park, harder on the tight corners, and no more capable where it counts.

Neither replaces a car if you want to explore.
Uber, Lyft and the local Holoholo app all work on Maui, and the County runs a fixed-route bus. Both are useful for a specific trip and neither is a way to build a sightseeing day. How each one actually behaves — fares, routes, where availability thins out — is in our getting around Maui guide.
Book early in peak periods. Maui runs out of cars before it runs out of visitors.
Photograph the car at pickup. Existing damage you did not record becomes your damage at drop-off.
Never leave luggage or valuables visible. A full car in an empty lot is the one thing to avoid.
Pull over when traffic stacks up behind you. Locals are driving to work on the road you are sightseeing on.
Rent for the days that leave the resort. Paying for a car to sit in a hotel lot is the easiest saving on the trip.
Yes if you stay in Wailea or Kāʻanapali, book tours with pickup and accept less spontaneity. For a typical first trip a car is easier and usually cheaper than the alternatives.
Count the days that leave the resort. On a seven-night trip with two resort days and a guided tour, four days of car is often enough.
No. The standard Hāna Highway route does not require four-wheel drive, and a smaller car is easier on it.
The airport is the most convenient for most visitors. Compare the all-in price and the pickup logistics before assuming it is also the cheapest.
No. Uber, Lyft and Holoholo are fine for a dinner or an airport run, and neither they nor the bus will carry a day of sightseeing.
Compact or midsize. Beach lots and the Hāna Highway both reward the smaller car.
