For the past few years, CR has been going back to car owners who did not answer the initial survey to gather additional information, and to include a greater number of the newest vehicles. These later responses have been incorporated into the ratings found in our annual
April autos issue.
With the new data, CR’s sample size of 2018 Model 3s nearly doubled, bringing the total number of Model 3s involved to
more than 500. These latest survey responses contained a relatively high number of reliability complaints.
