Chevrolet Silverado 1500 4th gen (T1XX) (2019 – 2025)

Reliability score : 7.4/10

The 4th generation Chevrolet Silverado 1500 (codename T1XX) is an essential full-size pickup truck on the North American market. Launched for the 2019 model year, it received a major facelift in 2022 (often referred to as '2022.5') which corrected its main flaw: an interior initially considered too basic compared to the competition (Ram 1500, Ford F-150).

🎯 Verdict

The 4th generation Chevrolet Silverado 1500 is a pickup truck with two faces. If you opt for the 3.0L Duramax Diesel engine, it's a big YES: this engine is a masterpiece of efficiency, offering V8 torque with the fuel consumption of a compact SUV, while boasting excellent reliability.

The recurring hydraulic lifter problems linked to the DFM system are a costly sword of Damocles out of warranty. It is imperative to favor the facelifted models (2022 and newer) to benefit from an interior worthy of the name, as the 2019-2021 versions show a glaring technological and qualitative lag compared to the competition.
