It sometimes reads like a terrible love story, the relationship between Consumer Reports and electric car company Tesla . Consumer Reports withholds its affection, Tesla addresses its errant ways and not long afterward, the two come happily together until the next car review.

We saw this happen in late 2015, when Consumer Reports assigned Tesla’s Model S a “worse-than-average” rating in an annual report about the predicted reliability of new vehicles, knocking down the company’s share price by more than 10 percent in one day. Later, the car was re-instated by Consumer Reports as a top-rated ultra-luxury sedan after consumers said its reliability had improved, and it updated its software to include automatic emergency braking at highway speeds.
