America's best selling truck, the Ford F-150, has been for decades, but lately there seems to be a lot of chatter online about reliability concerns. Some owners have had engine, transmission and electrical system problems, while others have said their trucks have been bulletproof. We don’t know if these are common problems or if they are just being amplified by social media. If you are thinking about purchasing a new or used F-150, how concerned should you be about issues to come? Is one brand or model year more reliable than another? But where do F-150s stack up against competitors like the Chevy Silverado or Ram 1500 in terms of long term dependability?
