2002 GMC Sonoma

Source: New Car Test Drive


GMC Sonoma can be a hard-working commercial truck, a pre-runner-style sport truck, a hardy off-road scrambler, or even a comfortable sedan with a pickup box out back. More standard equipment, more options, and a simplified model lineup all enhance Sonoma's value for 2002.

Anyone shopping for a cost-effective midsize pickup should be able to find a Sonoma to serve his or her needs. A quietly handsome appearance, healthy V6 torque, and a myriad of options all argue in the Sonoma's favor.

Model Lineup

The Sonoma line ranges from reliable work trucks to capable off-road machines. GMC offers a huge selection, with two- and four-wheel-drive; Regular, Extended and Crew Cabs; short and long beds; Sportside and Wideside styling, and a half-dozen different chassis packages.

Base SL trim ($13,756) now includes air conditioning. Starting at $14,874, SLS adds interior upgrades, a chrome grille, body-color bumpers and just about everything that used to be included on the top-level SLE, which has been discontinued for 2002.

All Sonoma Crew Cabs ($24,373) wear the SLS badge, but carry additional standard equipment, including a V6 engine, automatic transmission, cruise control, leather-wrapped tilting steering wheel, power locks with remote keyless entry, deep-tinted glass, four-speaker CD stereo, chrome bumpers, fog lamps, a limited-slip rear axle and a bed liner.

A 120-horsepower 2.2-liter inline-four is standard on 2WD models. An alternative-fuel version is available that burns gasoline, Ethanol-85, or any mixture in between. The Vortec 4300 4.3-liter V6 is standard on 4WD Sonomas, where it is rated 190 horsepower. The same V6 is optional on two-wheel-drive models but rates only 180 horsepower in that variation.

Five-speed manual and four-speed automatic transmissions are available.

Regular-cab 2WD's come with a Smooth Ride Z83 suspension and P205/70R15 tires. Extended-cab and four-wheel-drive models come with the Z85 Heavy-Duty suspension, designed for high payloads and towing. Regular-cab 2WDs can have Z85 for $64.

Or, buyers of 2WD Regular and Extended cabs can choose the ZQ8 Sport suspension, which enhances handling and goes a long way toward making the Sonoma drive like a car. This is accomplished with shorter ride-height springs, high-performance deCarbon gas shock absorbers, urethane jounce bumpers, front and rear stabilizer bars, specially tuned variable-ratio power steering and wide 8-inch aluminum wheels with Goodyear P235/55R-16 tires.

Off-road enthusiasts may opt for the ZR2 Highrider suspension, with Bilstein gas shock absorbers, 31x10.5R-15 all-terrain tires, and special springs, shocks, wheels and tires for a higher and wider stance. ZR2 Sonomas also come with a shield package, wheel flares and, new for 2002, identifying decals.


The GMC Sonoma is an attractive truck with a smooth, aerodynamic hood that wraps around at the front end. Its clean exterior lines include a body-colored front bumper (on SLS), as well as a headlamp design that integrates all forward lighting functions into a single unit. Composite headlamps are standard, with fog lamps available as an option. The front license plate bracket is molded into the charcoal-colored lower valance, while a center step cutout in the rear bumper gives easy access to the cargo area. The stiff, box-section ladder frame dips in the center to make it easier to step up into the seats, without sacrificing ground clearance for off-highway use.

A clamshell-style third-door on the driver's side is now standard on Extended Cab models, making it easier to load personal gear, pets and an occasional passenger.

Maximum towing capacity is 6,000 pounds (for a 2WD Extended Cab with a 4.3-liter V6 engine, automatic transmission, and aftermarket weight-distributing hitch). The standard step bumper is capable of handling trailers of up to 3,500 pounds.

Four-wheel-drive models come standard with InstaTrac, a shift-on-the-fly system that allows the driver to shift between two- and four-wheel drive by pressing a button. An optional locking rear differential ($270) improves traction in slippery conditions.

The bed on the Crew Cab model measures just 55 inches (4.6 feet), short when compared to standard six-foot beds.

Interior Features

The Sonoma offers a good seating position, with an open, airy feel. A sloping hood, narrow A-pillar and unobstructed views to the rear make for good visibility in all directions.

The interior is roomy, comfortable and functional. The long, wide body, along with a relatively thin door design, translates into impressive shoulder and hip room for a compact pickup. Seat choices are high-backed bucket seats for two passengers, a bench seat for three, or a reclining 60/40 split bench. Front bucket seats are standard on four-wheel-drive SLS regular cabs along with all Crew Cabs and four-wheel-drive extended cabs. Driver lumbar adjustments and reclining backrests enhanced comfort in our test model.

Extended-cab Sonomas have a single fold-down jump seat for the occasional rear occupant, though there isn't a lot of space back there for an adult.

Four-door Crew Cab models offer comfortable rear seats relative to this class. The seatbacks are slightly raked, an improvement over the upright designs found in some other mid-size crew-cab pickups. Rear legroom is adequate for people with feet that are small enough to slide under the front seats. Getting out of the back seats is a bit awkward, however, because it requires pulling your feet in and threading them between the B-pillar and the seat bottom. Also, the rear door handle is a bit awkward. We use the phrase "a bit" because the little people who are most likely to ride back there probably won't complain.

The sculpted instrument panel includes radio and ventilation controls angled 15 degrees toward the driver for improved accessibility. One neat detail is a passenger-assist grip located on the dashboard. Up-level models have two dash-mounted power outlets below the ashtray. The center console can accommodate an optional cassette player. Other options include power windows and door locks, tinted glass, and an upgraded remote keyless entry system with security alarm. Safety features include tall integral headrests, and a seat-belt design that allows the belt to travel with the seat. That provides a safer, more comfortable ride for occupants of all sizes.

Driving Impressions

The GMC Sonoma come with a choice of suspensions and they should be chosen carefully. A Sonoma 4x4 with the Z85 Heavy Duty suspension offers jouncy ride quality. It is at its best when hauling a heavy load or pulling a trailer, and rides better with a cord of wood in the back.

The Z83 Smooth Ride suspension is more comfortable for everyday use, yet still works well for the light-duty work most compact pickups perform.

The Vortec V6 engine delivers healthy throttle response across the power band, which makes everyday driving enjoyable. Passing maneuvers can be completed without drama. On 4WD models, the V6 is rated at 190 horsepower at 4400 rpm and 250 pounds-feet of torque at 2800 rpm. When fitted on 2WD models, the V6 produces 180 horsepower and 245 pounds-feet of torque at the same engine speeds. Both V6 variants use sequential port fuel injection and offer an excellent combination of horsepower and torque.

Sonoma's Insta-Trac electronic transfer case is easy to operate. Simply push a button to shift between two-wheel drive and four-wheel drive. Low range is available for traversing steep or slippery ground.

Driving off road is aided by the Sonoma 4x4's high ground clearance, optional locking differential, aggressive tires, gas-pressure shocks and heavy-duty multi-leaf rear springs.

We particularly enjoyed the feel of the 4WD Sonoma's brakes. Brake pedal travel is relatively short, with good feedback. Four-wheel discs are standard on four-wheel-drive models. Two-wheel-drive Sonomas come with disc brakes in front and drum brakes in the rear. All Sonomas have four-wheel ABS.


It's been around for a while and it may not attract a lot of attention, but the GMC Sonoma is a capable compact truck. With an almost bewildering array of models and options, the Sonoma offers plenty of choices to suit a wide range of drivers.

Safety Ratings help

What do the Safety Ratings mean?

The National Highway Traffic Safety Administration (NHTSA) performs independent crash testing of new vehicles and then assigns them a score based on their performance. The overall crash test rating is based on how a vehicle performs in the following tests:

Driver Crash Grade:

Measures the chance of a serious injury to a crash test dummy that is placed in a driver's seat and driven into a fixed barrier at 35 MPH. A five-star rating means there is 10 percent or less chance of injury.

Passenger Crash Grade:

Similar to the driver crash grade, only now the focus is on the passenger.

Rollover Resistance:

Simulates an emergency lane change to measure the likelihood of a vehicle rolling over. A five-star rating means there is 10 percent or less risk of rollover.

Side Impact Crash Test - Front:

Focuses on the front side of a vehicle. It simulates crashes that can occur in intersections by striking a 3,015-pound weight against the side of a vehicle at 38.5 MPH. A five-star rating means there is 5 percent or less chance of injury.

Side Impact Crash Test - Rear:

Similar to the front side impact test only now the focus is on the rear passenger.

Original Warranty  help
Original Warranty
An original warranty is the warranty associated with a vehicle when it is brand new. In addition to the original warranty, select items, like tires, are typically covered by respective manufacturers. Also, an act of Federal law sometimes provides protection for certain components, like emissions equipment.
The original warranty is often broken down into multiple sections, including:
Basic Warranty:
Typically covers everything except for parts that wear out through normal use of the vehicle. Examples of non-covered items are brake pads, wiper blades and filters.
Drivetrain Warranty:
This warranty covers items the basic warranty does not protect. Wear and tear items such as hoses will not be covered, but key items like the engine, transmission, drive axles and driveshaft often will be.
Roadside Assistance:
The level of service differs greatly with this warranty, but many manufacturers offer a toll-free number that helps provide assistance in case you run out of gas, get a flat tire or lock your keys in the car.
Corrosion Warranty:
This warranty focuses on protecting you from holes caused by rust or corrosion in your vehicle's sheet metal.
Please check the owner's manual, visit a local dealership or look at the manufacturer's website to learn more about the specifics of the warranties that apply to a vehicle.

Basic 3 Years/36,000 Miles
Drivetrain 3 Years/36,000 Miles
Corrosion 6 Years/100,000 Miles
Roadside Assistance 3 Years/36,000 Miles

GMC Certified Pre-Owned Warranty  help
Certified Pre-Owned Warranty
To be eligible for Certified Pre-Owned (CPO) status, vehicles generally must be recent models with relatively low mileage. CPO vehicles must also pass a detailed inspection, outlined by the manufacturer, which is measured by the number of inspected points.
Warranty coverage can vary from one manufacturer to the next. While most certified pre-owned programs transfer and extend the existing new car warranty terms, others offer a warranty that simply represents an additional year and mileage value. Always check with the manufacturer for the specific warranties they offer.
Common features and benefits of Certified Pre-Owned warranties include:
Age/Mileage Eligibility
To even be considered for certification, a car must be a recent model year and have limited mileage. The exact requirements are established by individual manufacturers.
Lease Term Certified
Some manufacturers offer certified pre-owned cars for lease. The length of the lease is often shorter than a new car lease, but it will cost you less.
Point Inspection
These inspections entail a comprehensive vehicle test to ensure that all parts are in excellent working order. The point inspection list is simply a numbered list of exactly what parts of the car are examined. While many inspections range from a 70- to 150-point checklist, most are very similar and are performed using strict guidelines. Ask your local dealer about specific details.
Return/Exchange Program
Some manufacturers offer a very limited return or exchange period. Find out if you will get the sales tax and licensing/registration fees back should you return or exchange the car.
Roadside Assistance
Most certified pre-owned programs offer free roadside service in case your car breaks down while still under warranty.
Special Financing
Reduced-rate loans are available through many certified pre-owned programs. Manufacturer-backed inspections and warranties help eliminate the risks involved with buying pre-owned, so buyers who qualify can take advantage of the great offers.
Transferable Warranty
When a new car warranty transfers with the certification of the car and remains eligible for the next owner, it is known as a transferable warranty. Once the original transferable warranty expires, an extended warranty takes effect.
Warranty Deductible
This is the amount for which you are responsible when repair work is performed under the warranty. Some manufacturers require a deductible while others don't, so always ask.

2-Year/24,000-Mile1 CPO Scheduled Maintenance Plan.

12-Month/12,000-Mile2 Bumper-to-Bumper Limited Warranty.

5-year/100,000-Mile3 Powertrain Limited Warranty.
