The GMC Suburban is a series of cars produced by the GMC division. The first generation 1935 Carryall Suburban was one of the first all-metal pickup trucks. The current GMC Suburban is a full-size SUV with three rows of seating, a pickup truck chassis, and a V8 engine offered in all-wheel drive. The extra length gives it full cargo space and nine seats for rear passengers. It was produced from 1973 to 2013 and from 2016 to 2020 in one-and-a-half-ton and three-quarters-ton versions. GMC discontinued this option on the tenth-generation model in 2013. The GMC Suburban was produced in 1941, 1942, and 1946. Beginning in 1953, GMC Suburban was available with a four-speed Hydra-Matic automatic transmission, starting in 1954. The 1952 Suburban was available with rear doors or rear fenders. The front seat was split into two driver-side seats and one passenger-side seat that moved forward to access the two rows of rear seats (the second row has 2/3 seats). To access the third row of seats, passengers had to slide forward between the front passenger seat and the second row of seats. All GMC trucks received a redesigned hood, recessed front fenders, a trapezoidal grille, and a V-shaped speedometer that was also typical of passenger vehicles. The 1960-1961 design was inspired by Chevrolet trucks of the late 1950s which featured large oval vents above the grille, independent suspension on the front wheels, the hood design became more conservative, and the large vents were eliminated. In 1964, the windshield was improved and was made flatter, and the door windows were enlarged. In 1997, GM introduced the then-North American pickups to the Brazilian market, replacing the long-awaited C Series. The Brazilian version of the Suburban was also redesigned during this period and was produced until 2001.

The GMC Suburban, acclaimed for accommodating larger families, has historically faced three significant issues: starting problems, fuel pump failures, and transmission clunking. Starting difficulties arise from numerous culprits such as depleted 12v batteries, loose or corroded battery terminals, defunct key fob batteries, or overarching electrical system glitches. Issues with the starter, alternator, or relay, given their limited lifespans, can obstruct ignition, and fuel-related hitches can spring from obstructed fuel filters, malfunctioning fuel pumps or injectors, or simply an empty tank. Worn-out spark plugs, coils, wires, or a malfunctioning ignition switch can further complicate the starting. Notably, 2001 models occasionally experienced post-switch-off non-restart issues, with malfunctioning gauges and, in some instances, ignition switches that needed wiggling - a possible hint at a faulty ignition switch inadvertently activating the security system. Experts have advised exploring the security system and the vehicle's onboard computer, and although diagnostic codes related to the fuel pump were detected, their exact meaning remained unclear. More uncommon causes include engine failures from overheating, timing belt issues, rodent damages, or immobilizer errors. The vehicle's fuel pump, integral for shuttling fuel to the engine, has also shown signs of failure, particularly with a conspicuous high-pitched noise, stalling, sputtering at high speeds, reduced acceleration power, or starting troubles. Normally, a functional pump emits a buzz during ignition, indicating the fuel line's priming; its absence might signify malfunction. Interestingly, a manufacturer-provided intermediary harness, once deemed vital, was found unnecessary. Meanwhile, the 1997 GMC Suburban had instances where the fuel pump didn't make the typical sound, suggesting potential malfunctions. Recommendations for these models encompassed using a funnel to listen for pump activity or tapping the tank to temporarily solve the issue.
