Expert 1998 GMC Sonoma review

Full article
our expert's take

The 1998 GMC Sonoma pickup truck, cousin to the Chevrolet S-10, comes withdual air bags to protect driver and passenger.

It also comes with a passenger-side air-bag cutoff switch. If an infantcarrier is going to be placed on the passenger seat or if you are going totransport your favorite pet (dogs, cats should ride in the cargo bed, ofcourse), the bag can be turned off to prevent injury to the seat’s occupant.Or, if no one is in the seat, you can turn it off so as not to run up therepair bill in a collision when two bags would deploy if the switch isn’tused.

However, we’ve just spent far more time writing about the passenger-sidebag and the cutoff switch than GMC spent in designing a useful system.

To alert the driver and passenger that the bag is off, a light on thekeylock used to deactivate the bag lights up to say “off.”

On the ’98 Sonoma extended cab we tested, however, the “off” light wasblocked by the steering column. Couldn’t see the light. It wasn’t until wedropped an envelop on the floor and stooped over to pick it up at the stoplight that we noticed the light was on and the bag was off.

GMC (and Chevy S-10) engineers need to redesign the system–pronto.

The Sonoma extended cab we tested is roomy and comfortable, though more sofor the driver than the passenger who is forced to rest his or her feet on thecatalytic converter bulge in the passenger’s side floor. When the engineersredo the light maybe they’ll redo the converter, too.

The suspension on this pickup was on the soft, car-like side to keep roadharshness out of the cabin upfront and in the rear, where a fold down jumpseat is housed to hold a child.

To get in back there’s a side access, or third, door on the driver’s side.To open it you must first open the driver’s door to expose the access doorhandle. That third door runs $375.

Some nice touches included huge outside mirrors for excellent side and rearvisibility, especially useful for truck buyers who might carry cargo in thebed someday; side-vent rear windows; a pair of power plugs under theinstrument panel along the floor to handle accessories; 1 1/2-inch longer seatbottom cushions for improved thigh support on long drives; and push-button 4WDactivation.

GMC placed a storage tray in the center console in front of the gearshiftknob to give occupants a convenient mini storage area, but being housed behindthat knob sacrifices lots of convenience.

The Sonoma we tested was powered by the higher-output (190 h.p./245foot-pounds of torque versus 180 h.p./240 foot-pounds of torque) version ofGM’s 4.3-liter V-6 rated at 16 m.p.g. city/21 m.p.g. highway with an optional4-speed automatic with overdrive. A 5-speed manual is standard.

Base price for the 4WD extended cab: $19,773 with our test unit adding$1,602 for a marketing option package including SLS sport decor, upgradedAM-FM stereo with ca ssette and clock, aluminum wheels, the high output V-6,air conditioning, tilt wheel and speed control; $1,070 for the 4-speedautomatic; and $510 for freight.

To save some dough you can go two-wheel-drive and get a 2.2-liter, 120-h.p.4-cylinder. But the first time 6 inches of snow fills the road or that roadtakes a 30-degree path skyward, you may have wished you stuck with 4WD and theV-6. Also, towing capacity with the 4 cylinder is 2,000 pounds, but 6,000pounds with the V-6.

Look for Sonoma to undergo its next styling change in 2001 as a 2001 or2002 model. At that time the converter hump sticking up like a volcano on thepassenger’s floor is supposed to be removed after only a little more than 15years of consumers having to put up with it.

  • I know I can go anywhere and make it.

    I think it's great! It's very reliable and would be great for anyone who needs something dependable. Would be excellent for a work truck or commute.

  • 4 wheel

    truck has cheap metal for the body but the 4 wheel is the real attraction of this truck. ive taken mine up quad trails. i would never sell or trade but i would recomend toyota for someones first truck. the gmcs need more love than any other truck so it takes a mechanic to own one.

  • low budget truck

    i wrote a review about my truck,in nov 09.Now is feb 2011,i still have my truck,since then,the starter went out,it now has 139,000 miles.I guess i can still squeeze a bit more out of it,it drives well,when i get to about 75-80 mph it sometimes jumps out of gear.....at times, i`m tired of it ,sometimes i think i can go a little longer with it.I wouldn`t dare drive really long distances with it,40 minutes max.......i`ll probably end up keeping it,but i can`t resist the temptetion of a better truck.....

  • it will do...for a low budget truck

    I got mine in 03,now is nov 09,got it when it had 73k miles now it has 131k,have had a few problems with transmission,.for the longest time i thought the tran. went bad ,and after 3 mechanics saying that i need to rebuld or a new transmission,i left it the driveway for a year,plus.and then took it to a friend of mine mechanic from church,and found out that was the crank shaft sensor,the wiper blades motor is going in and out,.....It`s a good truck,not too fancy....but if u change u`re fluids on time ,you may have the chance to squeeze more out of it,i`ll keep mine until it dies,good on gas,mine is 2.2...i`m a big guy,the only complaint that i have is,i wish i would have gotten an ext. cab.

  • Solid Truck

    Bought truck with 113,000 miles on it, have driven it now with 118,000. Have owned a 96 S-10(245,000 miles) and 95 Blazer (275,000 miles). Chevy's S-10 truck series have almost been bulletproof for me-as long as regular work done on intervals. Could not say enough great things about this truck. Extended cab leaves plenty of room to haul cargo inside and being able to stretch out. Only complaint to be the 4.3L V6 after the 1997 model year seem sluggish. But my truck does run the BFGoodrich Allterain T/A tires (31x10.5).

  • Good and Bad

    This truck is an interesting one. It is hard to insult it yet hard to complement. The V-6 engine is one of the best out there and the interior is quite comfortable. On the other hand, it has some of the worst, low-grade interior materials I have ever seen. This kind of plastic could have come from a fisher price toy. It falls apart very quickly. If you don't mind subpar build quality then this truck is a great value. Beware of the engine. It had to be replaced at 130,000 miles.
