Consumer Reports has some unfavorable things to say about the pickup vehicles Chevy Silverado and GMC Sierra. It claims that dependability and engine problems are becoming more prevalent. According to CR’s most recent survey of all 2021 cars, these trucks are tied for the position of most likely to experience serious engine issues.
What are the “engine and reliability issues?”
Because the two pickups are “the same trucks sold under different labels,” according to CR, they are connected. Additionally, 4% of Silverado and Sierra customers reported having significant engine difficulties in the past. These included cylinder head problems and replacing the whole engine. These included valvetrain difficulties, failures of the head gasket, problems with the supercharger or turbocharger, and timing chain or timing belt troubles.
The Silverado and Sierra both scored one out of a potential five points for dependability, which is the lowest possible rating. Ownership over the last 12 months is covered by the survey. Because they are all relatively new automobiles, CR observes that “it doesn’t take a high percentage to stand out. After all, the first few years of a car’s life are supposed to be trouble-free.
These problems ought to have been resolved by the refresh that was published this year. Additionally, GM performed a pre-refresh with the introduction of the 2022 Silverado 1500 Limited and 2022 GMC Sierra 1500 Limited. But even if the new 2022 models have fixed these flaws, there may still be difficulties with the earlier models.
Sierra and Silverado offered six engines in 2021
For 2021, there were four normally aspirated engines, a 2.7-liter LB3 turbocharged four-cylinder engine, and a 3.0-liter LM2 I6 turbodiesel Duramax engine. These featured the naturally aspirated 6.2-liter L87 V8 gas engine, the 5.3-liter L82 V8, the 5.3-liter L84 V8, and the 4.3-liter LV3 V6 engine.
Over 17 main trouble area categories, the consumer watchdog organization ranked the models most likely to experience issues. The group also includes problems with the Major Engine, Engine Cooling, Transmission, Drive System, Electrical System, and Climate systems. The reliability data used in this analysis comes from surveys of Consumer Reports members who own one- to three-year-old cars.
