Chevy Silverado HD Tops Segment In 2021 J.D. Power Vehicle Dependability Study

The 2021 Chevy Silverado HD finished atop the Large Heavy Duty Pickup segment in the recent 2021 J.D. Power Vehicle Dependability Study.

The J.D. Power Vehicle Dependability Study attempts to rank automakers and vehicle models based on their overall reliability. To do this, the study surveys original owners of three-year-old vehicles and asks them to record the various problems they’ve experienced with their car, crossover, truck or SUV. It then ranks makes and models based on the number of problems experienced per 100 vehicles on the road, assigning them an associated ‘PP100’ score. The study asks survey respondents about 177 specific vehicle problems grouped into categories such as entertainment, powertrain and driving experience, among others.

This year’s edition of the annual survey found the Chevy Silverado HD was the most dependable vehicle in the Large Heavy Duty Pickup category. The Ram HD finished the runner-up position to the Chevy Silverado HD, however, it’s worth noting that the Chevy was the only vehicle to perform at or above the segment average in this study.

Interestingly, the Silverado HD appears to have far outclassed the closely related GMC Sierra HD with regard to dependability in this study, despite the fact the two trucks share a platform, powertrain options and an abundance of other parts and components.

J.D. Power says many of today’s three-year-old vehicles leave something to be desired with regard to the dependability of their technology, which “continues to function poorly or inconsistently.” Major failures with regard to the engine, transmission or other crucial vehicle systems are uncommon, however, so while automakers have room for improvement with regard to technology, the reliability of their mechanical systems seems to be improving year-to-year.

The Chevrolet brand itself also performed well in this study, achieving a PP100 score of 115, well above the industry average of 121. GMC, by comparison, found itself toward the bottom of the ranking with a PP100 score of 143.

  1. the last gen probably brought up the score the only issue I had with my 18 1500 was a dash squeak. what is better about the new gen? I took one on a 2 hr. test drive and I did not feel any driveability or ride difference I am cloth LT non z71 guy and I noticed I had to buy packages to get things I like and end up with stuff I do not care about the only thing I really liked was the box volume was increased but you could not get fog lights no way no how

  2. Redesign the fugly front already!! While you’re at it paint the frames instead of using the sludge currently used. They rust immediately due to that crud wearing off

    1. that water or wax based whatever gm calls is useless. if you live in the salt belt and you are keeping your truck long term invest in getting it re-coated

    2. Seriously, it is the ugliest front end on a truck ever. Fire the design team that headed that one. Look at the Super Duty, then look at this ugly thing.

  3. The difference between the Chevy version and the GMC version is really odd since they’re built in the same plant (Flint, MI) same assembly line by the same workers.

    1. I would guess the difference is chevy sells a lot more of lower trim/optioned trucks and gmc proportionately sells more high content trucks,the drivelines do not know if they are going into a chevy or gmc until they meet up on the line. more content more problems
