Here’s the breakdown of certain GMC Sierra years to avoid that you should not consider buying to prevent critical frequent issues and costly repairs over the period.

2005 GMC Sierra

If you’re shopping for a used GMC Sierra pickup, the initial model years of its fifth-generation pickup should be avoided. These trucks were known for having issues like seizing headlights and seat heaters as well as AC issues and harsh transmission shifting that can pose potential hazards.

Owners reported issues with their infotainment system control pillar and inability to adjust headlights. Furthermore, these trucks were subject to multiple recalls due to temporary loss of steering that impacted over a million vehicles.

Even with its numerous shortcomings, the Sierra scored 7 on our Owner Reliability Score. Unfortunately, you should expect costly engine work (15%) and transmission repairs (20%) from time to time; additionally, these trucks received poor crash test ratings in government testing.

2007 GMC Sierra

The second year in the list of GMC Sierra years to avoid is 2007 as its users have reported various concerning issues that were experienced multiple times. GM’s second-generation Sierra pickups were an instantaneous success when they debuted, but not without its fair share of issues. 2007 and 2008 models exhibited multiple electrical issues including speedometer failure. Faulty interior lights also caused issues as did transfer case issues.

Corroded brake lines were an ongoing source of concern during these two years of Sierra production, often leading to reduced stopping power that poses serious safety threats.

Sierra’s chrome door handles are known to blister and break, creating a sharp hazard for owners. Furthermore, these two model years were involved with the Takata airbag recall saga; thus it is best to stay away from these pickups, although used ones could make good buys; just remember they may not be as reliable as some of GMC’s offerings on this list.

GMC Sierra Years to Avoid: 2008 Model

GMC Sierra truck models offer drivers an ideal balance between size and utility that makes them popular choices for transporting family or cargo. But knowing which GMC Sierra model years are dependable can be daunting at first.

Unfortunately, 2008 and 2009 models can present several problems to buyers when selecting used ones. These include electrical issues ranging from the speedometer, power seats, compass, radio, etc. that may require expensive repairs and could become a source of serious headaches for owners. Furthermore, these models often suffer from mechanical problems; to minimize these potential headaches buyers should avoid these two models altogether.

GMC Sierra Years to Avoid: 2012 Model

GMC Sierra trucks have long been a favorite choice of drivers who require power and the capability to tow heavy loads. GMC’s reputation for crafting high-quality vehicles extends into their pickups, which boast comfortable rides and quiet cabins.

GM’s 2012 Sierra was not without issues. It was included in the Takata airbag recall and owners reported mechanical problems – such as its transmission experiencing lurching or jerking while shifting and occasionally failing altogether.

As this year still boasts an above-average Owner Reliability Score, it would be prudent to keep an eye out for these models when searching for used GMC Sierras. These models tend to attract more complaints than their counterparts and may need costly repairs more frequently.

GMC Sierra Years to Avoid: 2014 Model

GMC Sierra pickup trucks have long been a top pick among drivers looking for powerful workhorses, but certain model years are riddled with issues that make them less desirable – such as 2007-2010 and 2013 Sierra models which have poor FIXD Reliability Scores and have an increased chance of costly repairs.

These model years also tend to experience issues with their engines and transmissions, including overheating and engine failure, which can be very costly. Transfer cases also present issues for off-road drivers.

Overall, when shopping for used trucks it’s best to avoid these three Sierra model years when possible; however, other model years may also present potential issues, so always do research before making your selection.
