Six Quick Facts About the GMC K25/K2500 Suburban

  • If you're having a tough time telling your C's from your K's with the GMC K25/K2500 Suburban, let us help you. Whether C or K, it's the same truck, essentially! The only difference is that if your want four-wheel drive, it the K version that you have to go to-the C version is a lower-key two wheel drive variant. Of course, the K's cost more-they're further down in the alphabet after all.

  • Is it a GMC or a Chevrolet? Sure, it's tagged as the GMC K25/K2500 Suburban, but Chevrolet has one that looks exactly like it! Well, there'll be no lawsuits here. The two are exactly alike in every way except for the symbol that they have upfront on the grille. That's because GMC owns Chevrolet, and sometimes "repackages" the same thing under both brands. For brand loyalists, perhaps?

  • The GMC K25/K2500 Suburban holds many distinctions. First, the Suburban tag has the record for longest continuous use. Starting from 1934, the Suburban tag has been produced under Chevrolet, Holden, and GMC. Second, it is the single most profitable product marketed and sold by General Motors-a record yet to be beaten.

  • Still feeling a little confused? The K25 and K2500 are, again, essentially the same GMC Suburban-the appearance and specs are nearly identical. The difference this time is with the engine. The K25 has a diesel engine powering it, while the K2500 houses a gasoline-powered engine under the hood. It may be a little confusing for some but it does give a wide range of choices.

  • In the Nicolas Cage movie World Trade Center-which was a tribute to the heroic efforts of emergency services personnel during the September 11 attacks-the brave fire chief that Cage portrays drives around in a GMC K25/K2500 Suburban. This is a nod to the rugged nature of the truck which is often used by real-life first responders and disaster relief personnel.

  • Just south of the border in Mexico, these rugged trucks are used as police vehicles. This specially designed GMC K25/K2500 Suburban is nicely decked out, too! It comes standard with a DVD player and a GPS navigation-enhanced radio-with a touch screen.

  • Two Major Gripes with the GMC K25/K2500 Suburban

    17 January 2013

    GMC trucks have a long, solid reputation of being extremely reliable workhorses. It's hardly surprising that GMC releases a lot of trucks on almost a yearly basis-including those under its owned marquee: Chevrolet. Among all the trucks, one of the most dependable is the GMC K25/K2500 Suburban. This amazing four-wheel drive truck has been the truck counted upon by many Americans for their ruggedness, durability, as well as the diverse range of applications that they can undertake. As great as the truck is, it does have its occasional hiccups. These are the two most common-good to know for any owner or would-be owners.


    Click-y, clunky transmission

    This problem was noticed specifically on the 1997 GMC K25/K2500 Suburban. It's actually an extremely rare problem that manifests when the truck has clocked up around 60,000 miles, but one worth mentioning due to the fact that it can cause a major accident if left unchecked and uncorrected. The cause is actually simple-the transmission system completely collapsed after normal usage. Were this to occur in low speeds, it would be a terrible inconvenience. At high speeds, however, the results can be disastrous, to say the least.

    The clear solution would be a replacement of the entire transmission system with an alternate that is complete remanufactured. Note that replacing like with like in this case is more likely to predispose the system to exactly the same thing down the road.


    Failing brake electric antilock

    An equally dangerous problem as the former is the apparent tendency of the antilock braking system of the 2003 edition of the GMC K25/K2500 Suburban to up and fail in the middle of driving. The speed at which this happens varies but the average lies around 65 miles per hour. The specific manifestation is that that the ABS warning light is illuminated, followed shortly by a shutdown of the truck-accompanied by failure of the power steering. The consequences of the problem are actually very terrifying-given that accidents are common results of these failures on-road.

    The only real way to deal with it is to get it back to your dealer for a clear and specific diagnosis-replacement can be conducted elsewhere, but it's best to know exactly what you're dealing with to get it done right.
