Two Major Gripes with the GMC K25/K2500 Suburban
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.
