2015 Car Reliability GPAs

Below are the 12 Best Cars and Trucks in America in 2015 by Auto Reliability Grade Point Averages, a measure of infrequency of reported serious problems, together with each model's GPA and the number of model years upon which the GPA is based.

Cars with a Perfect 4.00 GPA

Toyota Prius (GPA: 4.00, No. of Model Years of Data: 10)
Honda Fit
(GPA: 4.00, No. of Model Years: 8)
4-cylinder Toyota Highlander (GPA: 4.00, No. of Model Years: 5)
Toyota Camry Solara (GPA: 4.00, No. of Model Years: 4)
Lexus CT 200h Hybrid (GPA: 4.00, No. of Model Years: 3)

Toyota Prius C (GPA: 4.00, No. of Model Years: 3)
Toyota Prius V (GPA: 4.00, No. of Model Years: 3)

Cars with a GPA from 3.75 to 3.99

V8, 2-wheel-drive Toyota Tundra (GPA: 3.92, No. of Model Years: 5)
V6 Lexus ES (GPA: 3.88, No. of Model Years: 10)
V6 Toyota 4Runner (GPA: 3.81, No. of Model Years: 10)
Lexus RX Hybrid (GPA: 3.81, No. of Model Years: 5)
Lexus LS, a flagship luxury sedan (GPA: 3.75, No. of Model Years: 10)


A GPA based on a larger number of model years of data is likely more reliance worthy.

Computations of the Reliability GPA

There are several steps in computing a car’s Reliability GPA. First, numerical values are accorded CR’s overall ratings for each model year offering the necessary data. The values follow naturally from educational standards – a 4.00 for CR’s Much Better Than Average rating, a 3.00 for a Better Than Average rating, a 2.00 for an Average rating, a 1.00 for a Worse Than Average rating, and 0 for a Much Worse Than Average Rating. The sources of CR’s ratings are its New Car Buying Guide: 2015, its Used Car Buying Guide: 2015, and the April 2015 car issue of Consumer Reports

Next, an average is taken over each of the four model year periods 2005 to 2008, 2007 to 2010, 2009 to 2012, and 2011 to 2014. 

Finally, an average of the five 4-year averages is calculated using Microsoft’s Excel to obtain the car’s 2015 Auto Reliability GPA. 

A car’s GPA may be based on as few as 1 rated model year or as many as 10 rated model years. The number of rated model years depends on the availability of needed data. 

A brand’s Reliability GPA is the average of its car GPAs, and similarly, a manufacturer’s Reliability GPA is the average of its car GPAs.

The 50 Best Cars in America in 2015

Volume 8 of AutoOnInfo.net’s Car Quality Series is intended primarily as an aid to consumers in selecting a vehicle that both is reliable in the short term and provides a prospect of only modest repairs in the long term, and secondarily as an aid to auto industry analysts and reporters. To this end, it provides a list of the 50 Best Cars available in the U.S. in 2015 using the Overall Reliability GPA, now AutoOnInfo.net’s standard measure of infrequency of reported serious problems for several years, covering model years 2005 to 2014 for ranking pickup trucks, sport-utility vehicles (SUVs), family cars, wagons, small cars, hatchbacks, sport/sporty cars, coupes, convertibles, upscale cars, luxury cars, and hybrids, and includes each car’s reliability GPA and grade and the number of model years upon which the GPA and grade are based. As a further aid, it includes 2015 brand and manufacturer GPAs for comparison and contrast and for better assessing long term performance and ownership expenses. In addition, it offers more than 30 full color charts depicting each brand’s and car company’s share of the 10, 20, 30, 40, and 50 Best Cars and each brand’s and auto maker’s share of the best pickups, best large sport-utility vehicles, best midsize SUVs, best small SUVs, best family cars, best wagons, best small cars, best hatchbacks, best sport/sporty cars, best coupes, best convertibles, best upscale cars, best luxury cars, and best hybrids in America. It also names the minivan that came close to the cutoff, and gives some comparisons between this year’s Best Cars and last year’s.  For further study and better understanding of auto quality in North America, it offers 10 charts that display, using a bar graph with an axis value of 2.00 (for quick viewing of how much above or below average a brand’s or auto maker’s  Reliability GPA falls), the 2015, 2014, 2013, 2012, and 2011 Reliability Grade Point Averages of each major brand and manufacturer, as well as a line graph plotting the 2011 to 2015 Reliability GPA ranks of the 6 most prominent manufacturers by U.S. sales. Volume 8 in AutoOnInfo.net’s car quality series offers a new historical chapter entitled “The Growth of the Great Divide by Reported Serious Problems.” Two line graphs depict the changes over time.

The 100 Worst Cars in America in 2014

The 100 Worst Cars in America in 2014 offers lists of the worst cars and trucks available in the U.S. It uses AutoOnInfo.net’s Overall Reliability GPA covering model years 2002 to 2013 for ranking pickup trucks, sport-utility vehicles (SUVs), minivans, family cars, wagons, small cars, hatchbacks, sport/sporty cars, coupes, convertibles, upscale cars, and luxury cars in order to aid consumers in avoiding a vehicle that may require a larger number of repairs and a greater number of expensive repairs. To this end, it includes each car’s reliability GPA and grade and the number of model years upon which the GPA and grade are based, as well as brand and manufacturer GPAs for comparison and contrast and for better assessing long term performance and ownership expenses.   In addition, it is offered as an aid to auto news reporters and auto analysts for better understanding and assessing the differences and changes in brand and auto manufacturer product quality and sales.  Further to assist consumers, reporters, and analysts in better understanding auto quality in North America, it offers 10 color charts that display, using a bar graph with an axis value of 2.00 (for quick viewing of how much above or below average a brand’s or auto maker’s  Reliability GPA falls), the 2014, 2013, 2012, 2011, and 2010 Reliability Grade Point Averages of each major brand and manufacturer, as well as a line graph plotting the 2010 to 2014 Reliability GPA ranks of the 6 most prominent manufacturers by U.S. current sales.
