Gmc Sierra classic problems
The Chevrolet C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs. Through its entire production, the model line competed directly against the Ford F-Series and the Dodge D series (later the Dodge Ram pickup).
Used for both the model branding and the internal model code, "C" denoted two-wheel drive, while "K" denoted four-wheel drive. Four generations of the C/K series were produced, including the GM monikered second-generation "Action Line" and third-generation "Rounded Line" vehicles (colloquially aka Square-Body trucks). For the fourth-generation (colloquially also known as OBS trucks), Chevrolet kept using the C/K designation while GMC revised its branding, changing to a singular GMC Sierra nameplate (C/K remained as an internal model code).
For South America, the model line was manufactured by General Motors de Argentina from 1960 to 1978, Sevel Argentina from 1986 to 1991, and General Motors Brazil, who produced versions of the model line for Brazil, Argentina, and Chile from 1964 to 2001.
As GM entered the 1990s, the company revised its truck ranges, replacing the medium-duty C/K trucks with the Chevrolet Kodiak/GMC TopKick for 1990. For 1999, GM replaced the fourth-generation C/K pickup trucks with an all-new model line; in line with GMC, Chevrolet dropped the C/K nameplate (in favor of a singular Chevrolet Silverado nameplate). Initially marketed with its successor, the final C/K pickup trucks were produced for the 2000 model year. From 2001 to 2002, the final vehicles of the C/K model line were medium-duty chassis cab trucks.

Common Gmc Sierra classic problems
The GMC Sierra is a popular full-size pickup truck, but like any vehicle, it can have its share of problems. Here are some of the most common issues reported by owners of the GMC Sierra, based on the search results:
- Electrical Issues: The GMC Sierra also seems to have some problems with the electrical system. Issues like dash gauges not working, interior lights giving out, or the vehicle randomly locking or unlocking are all relatively common problems for the SMC Sierra.
- Heating System Problems: The GMC Sierra also has 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.
- Four-wheel-drive transfer case position sensor/selector switch failure: This is a common problem reported by over 450 owners of the GMC Sierra 1500. The 4WD transfer case encoder motor position sensor or the selector switch might fail, requiring a visit to a service department. A diagnostic test typically runs $88 to $111, but expect to spend more if the selector switch needs replacing.
- A/C temperature and air delivery mode door actuator failure: This problem has been reported by over 260 owners of the GMC Sierra 1500. When the air delivery mode door actuator fails, the HVAC system can’t deliver air to cool or heat the Sierra’s cab. This issue should appear as a fault in the A/C control module, which requires a diagnostic visit and potential repair costs for this full-size truck.
- Fuel level sensor failure: This problem has been reported by over 170 owners of the GMC Sierra 1500. The fuel level sensor in the gas tank can read the fuel level incorrectly, requiring replacement. RepairPal technicians recommend replacing the entire fuel pump module on high-mileage GMC Sierra 1500 models, which can cost around $1,000.
- Power Steering Loss: The 2015 GMC Canyon is being recalled to fix intermittent power steering loss. These trucks have had ongoing power steering issues because of corroded electrical connections inside the steering gear assemblies. GM plans on replacing the torque sensor cover assembly and applying anti-corrosion gel to the electrical connections.
- Battery Fires: Late last year, GM recalled 2021 Chevy Express vans after at least four battery fires. The batteries could short-circuit due to the positive battery cable coming in contact with the fuse block assembly.
These are some of the most common problems with the GMC Sierra, based on complaints from owners of this car. It's important to note that not all vehicles of this make and model will experience these issues, and many owners have reported positive experiences with their GMC Sierras. However, potential buyers should be aware of these common problems and consider them when making their purchasing decision.
