Experiencing recurring issues with a Chevrolet Silverado 1500 Z71, while the Colorado ZR2 model performed flawlessly, and now the 2025 Chevy Silverado 1500 ZR2 displays a check engine light.
In the evolving automotive landscape, automotive journalist Aram Krajekian brings a fresh perspective to the table. However, his recent coverage of the 2025 Chevrolet Silverado 1500 ZR2 with the 3.0L Duramax diesel engine has raised some concerning issues.
Owners of this popular model have reported a series of reliability problems primarily linked to the Diesel Exhaust Fluid (DEF) system. Issues include sensor malfunctions and problems with the DEF tank, which trigger the check engine light and can limit vehicle performance until repaired.
One such owner, Vince Shinaver, is grappling with these issues. Just 9,200 miles into his ownership, Vince's Silverado has a check engine light for the DEF system. He traded in a 2024 Chevrolet Colorado ZR2 for the 2025 Silverado, but the DEF system issue has limited its performance and towing capacity. Vince's story serves as an example of the potential downsides of brand loyalty.
Other owners have reported repeated DEF system warnings, causing frustration and questioning of the vehicle’s reliability. Some customers also report difficulties with dealership fixes and responsiveness, feeling that General Motors is not adequately addressing or resolving these problems.
Though not exclusive to the ZR2 diesel, broader reports highlight other model issues such as a defective hydraulic mechanism in the eight-speed transmission causing a “Chevy Shake” (vibrations), which can put strain on gears.
Despite these concerns, it's worth noting that GM recently extended the warranty on the 2.7L turbo four-cylinder engine due to its reliability. Additionally, the off-road capability and general driving comfort of the Silverado are still praised by many owners.
However, the reliability concerns, particularly those related to the DEF system and related emissions controls, remain a significant concern for diesel Silverado owners in 2025.
Other factors to consider when making a purchase decision include brand loyalty, performance track record, dealership accessibility, and fuel economy savings. Balancing these factors is crucial to ensure a satisfying ownership experience.
John Stewart, an automotive enthusiast, sums it up well: "I'll never understand people who continuously have issues with a particular brand and keep going back, thinking it's going to be different." Josh Wagner suggests keeping the 2.7L engine for its reliability and extended warranty.
Ownership requires careful consideration, and the potential issues with the DEF system on the 2025 Chevrolet Silverado 1500 ZR2 with the 3.0L Duramax diesel engine are a reminder of this.
