GMC has built a reputation on the quality of its trucks and SUVs, and the GMC Yukon XL 2500 is certainly up there among the ranks of some of the best SUVs ever made in America and the world. It was perfect in a sense because it could be used for both business and pleasure, and was certainly a very beefy, manly car. Since the 2500's debut in 1933-then as a station wagon-it has been the benchmark and leader in its class. It in fact holds the distinction as bearing the longest running nameplate in history. Still, it's not without its troubles. Here are the most common ones to help users have a much better experience with this American classic:
This particular problem plagues the 2001 Yukon at around 75,000 miles. Any trouble with brakes or the braking system in general is nothing laugh about, but as far as problems goes, this one is a little more subdued than what can be expected. It is actually very difficult to detect because, in most cases, it manifests as a more difficult to press brake. There are worst case scenarios, however, wherein the failure led to serious damage to the battery-these are thankful rarer.
The best thing is to have the ABS module checked out by the dealer. Even if they say that it's beyond the warranty and irreplaceable, aftermarket modules are always available, and they are actual great in quality and low in price.
Amazingly enough, this problem is still a fault on the 2001 Yukon XL 2500. It seems that year had a monopoly on braking problems. This one is simpler, more mechanical, and an inconvenience more than a hazard. The parking brakes on some 2500s simply wouldn't engage. Owners jerked and tugged all they wanted but the parking brake refused to keep the SUV in place. A simple trip to the dealer or even mechanic resolves this one lickety split, and shouldn't cost too much. Still, given that it's hard to keep the 2500 in place all day long, it's a problem that should be resolved as soon as it's encountered.
