To determine which vehicles will be the most reliable for the 2021 model year, Consumer Reports collected data on an estimated 329,000 vehicles and analyzed them across 17 so-called “trouble areas.” These trouble areas can include small issues like broken interior trim or buggy infotainment systems, or larger issues like transmission problems. Consumer Reports experts then use this data to give each vehicle a Predicted Reliability Score ranging from 1 to 100. The publication says that it must have at least two model years of data on hand for a vehicle to be considered for the Top 10 Most Reliable Cars list, so brand-new vehicles cannot be included in it.
Consumer Reports gave the 2021 Buick Encore a Predicted Reliability Score of 91 out of 100. The Encore was tied for second place with the 2021 Lexus NX, which also received a Predicted Reliability Score of 91. The 2021 Toyota Prius lead the way in the top ten ranking with a Predicted Reliability Score of 93.
The majority of reliability data for the 2021 Buick Encore was sourced from the 2018 and 2019 model-year Buick Encore. It received near-perfect reliability scores across the board, though it left some small room for improvement in the Engine Minor, Electric System and Body Integrity trouble areas. The Encore also showed considerable reliability improvements in 2018 and 2019 compared to the 2014, 2015, 2016 and 2017 model years – particularly with regard to its transmission and engine. The subcompact crossover received a minor update for the 2017 model year, which included revised exterior styling and some small interior changes.
