1987 Gmc Sierra problems
The Chevrolet Silverado is a range of trucks manufactured by General Motors under the Chevrolet brand. Introduced for the 1999 model year, the Silverado is the successor to the long-running Chevrolet C/K model line. Taking its name from the top trim level from the Chevrolet C/K series, the Silverado is offered as a series of full-size pickup trucks, chassis cab trucks, and medium-duty trucks. The fourth generation of the model line was introduced for the 2019 model year.
The Chevrolet Silverado shares mechanical commonality with the identically related GMC Sierra; GMC ended the use of the C/K nomenclature a model generation prior to Chevrolet. In Mexico, high-trim level versions of the Silverado use the Chevrolet Cheyenne name (not to be confused with the 2003 concept). Competing against the Ford F-Series, Ram Pickup, Toyota Tundra, and Nissan Titan, the Silverado is among the best-selling vehicles in the United States, having sold over 12 million trucks since its introduction in 1998 as a 1999 model year.
History
The Silverado nameplate made its debut for the 1975 model year, becoming the top trim level on all Chevrolet C/K trucks, slotted above Custom Deluxe, Scottsdale, and Cheyenne. For the 1968 model year (seven years before the Silverado), GMC C/K trucks used variations of the Sierra name (Sierra, Sierra Classic, Sierra Grande, and High Sierra). Even after the C/K series officially ended, GM still uses the CK and the CC in their current model codes, to denote a two-wheel drive (CC), and four-wheel drive (CK).
For the 1988 GMT400 model architecture, Chevrolet retained the C/K model nomenclature, with GMC branding its full-size line as Sierras. While sharing the same body and chassis, the model chronology of the Silverado and Sierra are different, with five generations of the Sierra, while four of the Silverado.
In 2018, at the NTEA Work Truck Show in Indianapolis, Indiana, Chevrolet unveiled the first medium-duty Silverado, expanding the model line to a 4500HD, 5500HD, and 6500HD chassis cab. Largely the successor to the 2003–2009 GMT560 chassis, the medium-duty trucks are exclusive to Chevrolet, with no plans for an equivalent GMC version. Instead, Navistar International (now partnering with GM) would sell the medium-duty trucks as a rebadged counterpart, called the CV. This is in fact a very similar nod to how the Avalanche did not have a GMC Yukon–based equivalent, but instead, Cadillac would take its place as the former's rebadged counterpart, the Escalade EXT.

Common 1987 Gmc Sierra problems
The GMC Sierra 1987 is known for several common problems that owners have reported over the years. These issues range from electrical problems to heating system malfunctions and engine knocks.
One of the most common problems with the GMC Sierra, especially the 2005 model, is that some vehicles seem to have problems with the Speedometer. This is an electrical and wiring issue, but it can be relatively hard to spot. The easiest version of this problem to spot is when the speedometer stops working entirely. However, that’s not the most common problem. If your speedometer stops working, you can use a speedometer on your phone to help limp your vehicle to a mechanic to get the problem fixed. Unfortunately, the most common version of this problem isn’t that the speedometer stops working; it’s that the speedometer stops giving an accurate reading. That can be a bit issue because you might get ticketed for speeding or take a curve at the wrong speed and lose control. Fixing this issue is also a mixed back. Sometimes replacing the sensors is all you need, but other times it’s a wiring or power source problem that is harder (and more expensive) to resolve.
Other electrical problems that are common with the GMC Sierra include dash gauges not working, interior lights giving out, or the vehicle randomly locking or unlocking. These issues can range from very mild to severe. Fixing these problems also has a widely variable cost depending on what repairs are necessary and how hard it is to access the source of the problem.
The GMC Sierra also seems to have some problems with the heating system. The heater in your Sierra might turn on randomly, even in the middle of summer. Thankfully the opposite doesn’t seem to happen, so you won’t have to worry about your heater suddenly turning off in the middle of a freezing winter drive.
In addition to these problems, engine knocks are a more serious issue that can be incredibly difficult to diagnose and repair. These internal engine knocks can be caused by a variety of factors, including faulty piston rings, the active fuel management (AFM) system, and the PVC system. These problems can lead to excessive oil consumption, premature spark plug degradation, and engine malfunction.
Finally, some GMC Sierra owners have reported problems with the speakers, particularly those in the door, which may go out over time. Most of these problems involve the speakers in the door, which typically quit working one at a time over several months.
In summary, the GMC Sierra 1987 is known for several common problems, including issues with the speedometer, heating system, electrical components, engine knocks, and speakers. While some of these issues are relatively minor and easy to fix, others can be more serious and require significant repairs. If you own a GMC Sierra 1987, it’s important to be aware of these common problems and to address them promptly to ensure the safety and reliability of your vehicle.
