Section 1It's worth noting that Consumer Reports' reliability rankings are based on owner-reported experiences rather than long-term durability testing, and many of the issues cited affect only a portion of owners. Even so, the results serve as a reminder that capability and reliability don't always go hand-in-hand.10. Chevrolet Silverado 1500Reliability Score: 40/100The Silverado remains one of America's best-selling vehicles, but some owners have reported recurring issues with GM's cylinder deactivation-equipped V8 engines.Additional complaints range from cooling-system concerns to electrical glitches involving keyless entry systems and wiring harnesses. While many Silverados provide years of dependable service, Consumer Reports' survey data suggests reliability remains a concern for a notable portion of owners.9. Jeep GladiatorReliability Score: 40/100The Gladiator combines Wrangler styling and open-air fun with pickup truck utility, but it also inherits some of the quirks that have long followed Jeep's off-road-focused platform.Owners have reported suspension-related complaints, electrical issues, and battery problems. Its unique design continues to attract enthusiasts, though reliability hasn't been one of its strongest selling points.8. GMC Sierra 1500Reliability Score: 40/100Sharing much of its architecture with the Silverado means the Sierra also shares many of the same mechanical concerns.Engine-related complaints mirror those found in Chevrolet's full-size pickup, while owners of higher-end trims have reported issues involving power-hungry luxury features and electronics. The Sierra remains a premium truck, but reliability scores suggest there is room for improvement.7. GMC Sierra 2500HDReliability Score: 37/100Heavy-duty truck buyers expect durability above all else, which makes reliability concerns particularly problematic in this segment.Consumer Reports points to transmission-related complaints, diesel emissions-system issues, and electronic problems affecting some Sierra HD models. For owners who depend on their trucks for towing and work duties, unexpected downtime can be costly.6. Chevrolet Silverado 2500HDReliability Score: 37/100Like its GMC brother, the Silverado HD faces similar challenges.Transmission behavior, emissions-system faults, and recall-related concerns have all affected owner satisfaction. While the truck remains a capable towing machine, reliability scores place it among the lowest-rated heavy-duty pickups surveyed.5. Tesla CybertruckReliability Score: 34/100Tesla's radical pickup has generated enormous attention since its launch, not all of it good.Owners have reported software glitches, camera-related issues, electrical faults, and concerns involving hardware quality. While Tesla continues to address many problems through software updates and service campaigns, reliability scores remain well below segment averages.4. Chevrolet ColoradoReliability Score: 29/100Chevrolet's midsize pickup offers impressive capability and modern technology, but reliability concerns continue to surface.Complaints have included transmission behavior, software-related issues, and battery-drain problems linked to electronic systems. While the Colorado remains a strong performer on paper, owner satisfaction has been impacted by recurring technical issues.3. GMC CanyonReliability Score: 29/100As the Colorado's corporate cousin, the Canyon shares many of the same strengths—and many of the same weaknesses.Owners have reported similar complaints involving transmissions, electronics, and software-related problems. Despite receiving updates and refinements, reliability scores remain among the lowest in the midsize truck segment.2. Rivian R1TReliability Score: 18/100The Rivian R1T helped redefine what an electric pickup could be, combining impressive performance with genuine off-road capability.However, Consumer Reports data suggests the innovative EV still faces reliability challenges. Suspension issues, drive-unit concerns, steering complaints, and 12-volt battery failures have all been reported by owners. As a newer manufacturer, Rivian continues working through the kinds of quality-control issues many startups encounter.1. Ram 1500Reliability Score: 5/100According to Consumer Reports' latest survey data, the Ram 1500 earned the lowest reliability score of any pickup truck evaluated.Owners reported a broad range of concerns, including electrical system problems, battery-drain issues, infotainment glitches, and powertrain-related complaints. The transition to Ram's new Hurricane turbocharged inline-six engines has brought impressive performance, but reliability concerns have overshadowed some of the truck's strengths.
