Tesla: myth or reality of the lowest rank in reliability? Discover the hidden truths behind the numbers

The burning question on the lips of car enthusiasts and future buyers of electric vehicles: Tesla, myth or reality when it comes to reliability? While the California manufacturer has revolutionized the automotive world, the latest rankings from Consumer Reports highlight a damning result: Tesla is ranked last among 26 evaluated brands, leaving many admirers perplexed.

Tesla's performance according to Consumer Reports

In this annual study, Tesla models from 2014 to 2019, notably the Model S and the Model X, received an alarming score of 31 points. By comparison, brands like Toyota and Lexus shine with respective scores of 77 and 73 points.

Brand	Reliability Score
Tesla	31
Toyota	77
Lexus	73

At the heart of these statistics lies a more nuanced reality. Tesla has undergone a difficult learning period, referred to as "production hell," where standardization and quality were not always guaranteed.

Recurring issues with older models

• 🚫 Electric propulsion system problems
• 🔧 Suspension malfunctions
• ❄️ Air conditioning system failures
• ⚠️ Deficient assembly quality (paint, finishes)
• 💻 Various electronic failures

A significant evolution: the transformation of models

It is crucial to note that Tesla has learned from this difficult period. Recent models, such as the Model 3 and the Model Y, represent a remarkable leap, achieving a reliability score of 81 points and featuring in the top 10 of reliable brands.

Period	Tesla Models	Reliability Score	Status
2014-2019	Model S/X (1st gen), early Model 3	31/100	26th out of 26 brands
2022-2025	Optimized Model 3/Y	Top 10	"Excellent" reliability

This improvement is the result of an increasing understanding of industrial processes. Unlike other well-established brands, Tesla had to build its expertise firsthand by learning to manufacture cars while producing its first models.

Tips for purchasing used electric vehicles

If you are tempted to buy a used Tesla, it is imperative to be cautious regarding the production year. Models prior to 2020 may pose risks of severe failures, particularly in complex systems.

• 🔍 Check the maintenance history
• ⚙️ Inspect the battery condition
• ⚡ Test all electronic systems

The answer to the question of Tesla's reliability therefore largely depends on the adopted perspective. The figures must be put into context to appreciate the extent of the transformations that have occurred. By approaching the question with an open mind, the hidden truths behind these numbers can reveal more than what a simple ranking can offer.
