most reliable electric vehicle (EV)

My research took me through various Reddit threads that discussed the reliability of different electric vehicles. The discussions spanned several years, with the most recent ones being very relevant to the query. There was considerable consensus around certain models being reliable, particularly the Nissan Leaf and Tesla models, although the latter had some mixed reviews. Some other models like the Chevrolet Bolt EV, Hyundai Kona Electric, and Mazda MX-30 EV were also mentioned, but these didn't have as much consensus. The sources were highly relevant to the query, with many users sharing personal experiences with their EVs. Given the nature of the discussions and the number of sources, the level of certainty is relatively high.

Nissan Leaf

Nissan Leaf

The Nissan Leaf was frequently mentioned as a highly reliable electric vehicle across several discussions. Users on these threads praised the Leaf for its low total cost of ownership, build quality, and longevity. One user even mentioned spending $0 on maintenance and only needed to rotate the tires once a year. However, a few users did express concerns about battery degradation, although others said their batteries had been replaced under warranty at no cost. The Leaf seems to be a popular choice among EV owners for its affordability and reliability.
Tesla Models

Tesla Models

Tesla models also came under the limelight, with Consumer Reports ranking them highly in terms of reliability. However, the reviews were mixed, with some users reporting problems with various systems, including the climate control, suspension system, and brakes, particularly for the Model S and Model X. For the Model 3, a "wait-and-see" approach was suggested due to issues with the vehicle's braking and touchscreen. Tesla's Autopilot feature also raised concerns among some users. Nevertheless, Tesla still ranks higher than any other automaker in Consumer Reports' "owner satisfaction" survey.
Hyundai Kona Electric

Hyundai Kona Electric

The Hyundai Kona Electric was also suggested as a reliable and low-maintenance option. Users praised its good warranty and the availability of cheap replacement parts due to its popularity. However, the discussion around the Kona Electric wasn't as extensive as those for the Nissan Leaf or Tesla models.
Chevy Bolt EV

Chevy Bolt EV

The Chevy Bolt EV was another model that came up in the discussions. While some users praised its battery longevity, others raised concerns about potential problems with defective parts that could require maintenance. The discussion around the Bolt EV was less conclusive compared to other models.
Mazda MX-30 EV

Mazda MX-30 EV

The Mazda MX-30 EV was highlighted in a few discussions, but it didn't receive a favorable review. Users critiqued its low range and described it as being more form than function. It seems to be less recommended compared to other options.

General Reliability of EVs

In terms of general reliability, most users agreed that EVs are very reliable due to having fewer moving parts than conventional internal combustion engine vehicles. This results in less potential for things to go wrong and lower maintenance costs, as EVs require no oil changes, timing belts, fuel filters, or spark plugs. However, there were also concerns about design mistakes by automakers due to the relative newness of the industry.

"EV Reliability"

Not used in article

"Do you go with consumer report ratings?"

  • Consumer Reports is a publication that gives ratings and reviews for various products, including cars.
  • The webpage discusses the ratings of electric vehicles (EVs) and compares the score of Tesla and EV6.
  • Tesla receives a mediocre review score of 78, while EV6 receives a much higher score of 91.
  • CR’s review score is based on a road test score earned after they purchase the car and long-term test it (usually for a year); they also give a predicted reliability score based on surveys from consumers who own the car.
  • CR is more representative of “Older Average Joe American Consumer” than people on the sub, according to one Redditor, and they tend to weigh qualities such as build quality, NVH, and comfort more heavily than technology and performance, which in part explains the difference between Tesla and EV6 scores.
  • CR must test a car and earn a score above a certain threshold and maintain above-average predicted reliability to earn the “recommended” stamp.
  • There are instances of cars that don’t earn a “recommended” stamp but get the highest road test scores in their category, such as the Chevrolet Corvette.
  • One Redditor argues that CR is a pay-to-play rating system with bad data collection methods and low sample sizes, but other Redditors dispute this claim and point to CR’s reputation for independence.
  • The text does not indicate that any EV is the most reliable or that reliability is a key factor in how CR assigns ratings.
  • Redditors debate the reliability of CR’s member surveyed reports, with some arguing that the surveys suffer from selection bias that exaggerates the difference between Japanese brands and European and American brands.
  • Some Redditors take issue with how CR rates advanced tech in cars, with one claiming that they knocked Tesla’s score because they didn’t understand FSD and had a hard time with it. This Redditor also argues that Tesla’s performance on highways and lack of spying on the driver should earn it a higher score.
  • Other Redditors dispute this claim and argue that CR rates cars more fairly and objectively than YouTubers who may have biases and fewer data points.
  • One Redditor observes that EVs are reviewed as both cars and consumer electronics, and this makes reviewing them difficult.
  • Criteria used to evaluate cars in CR are discussed in the text, such as safety, surface-street capability, and standard vs. advanced features.

"Most reliable EV’s?"

  • The webpage is a discussion posted on Reddit about the most reliable EVs and their critical components that we may expect to last at least 10 years with minimal or no issues.
  • The German ADAC publishes an annual statistic about car reliability based on how often the cars are called out for assistance. Eligible cars need at least 7000 registrations per year in the first two years of sale and must have been on the market at least three years. The statistic does not include calls related to owner negligence.
  • The majority of stranded cars (43 percent) were due to a failure of the 12V battery. ICE cars had a 40 percent higher incidence of breakdowns, though this is to be taken with a grain of salt since there are many older ICEs on the road and no such EVs.
  • According to the German ADAC, there is no system where EVs have a significantly higher chance of failure. Notably, the entire motor/motor management (including high voltage systems) for EVs seems to be far less of an issue than for ICE cars. However, the incidence of issues with the 12V battery seems to be identical across EVs and ICE cars. There was no significant difference in reliability between locks/keys/immobilizer systems for EVs and ICE cars.
  • The German ADAC website shows that the ID.3 and Model 3 seem to be performing well in terms of reliability.
  • Reddit users make various comments about the reliability of EVs. Some of these are:
    • German ADAC’s annual statistic shows that the incidence of breakdowns is 40 percent lower in EVs per 1,000 cars.
    • Toyota’s Corolla and RAV4 get bad scores in the German ADAC statistic for reliability, despite being considered highly reliable in the US.
    • Some Tesla owners report fit and finish issues or suspension issues, but the core EV components such as the battery, motor, cooling system, and heat pump seem to be solid and reliable, according to Consumer Reports.
    • Tesla and Nissan are identified as the most reliable brands of EVs by Consumer Reports. The Model 3 RWD is considered by some to be the most reliable EV due to the toughness of its LFP batteries.
  • The 12V battery in EVs is a common source of complaints and issues since lead acid batteries do not give any real warning when they are starting to fail. One Reddit user suggests that it may be feasible to have two smaller 12V batteries that are in

"How reliable are electric vehicles"

  • Most EVs are very reliable, as they have fewer moving parts in the engines/motors. This results in less potential can go wrong. Transmission issues are also rare.
  • Maintenance costs are generally far lower, since EVs require no oil changes, timing belts, fuel filters, or spark plugs, among other parts.
  • Batteries in an EV are likely to last for at least 200,000 miles, which is quite impressive.
  • A kWh of net battery capacity is likely to be able to last 6,000 miles on average before the battery degrades below 70% capacity. Based on this, a battery with 30-40 kWh could provide owners with at least 200,000 miles of driving before it needs any significant maintenance.
  • Some automakers are still making design mistakes with their EVs since the industry is still relatively new.
  • EV designs are changing rapidly, which could lead to them needing more trips to the shop than traditional ICE vehicles for at least a decade or two.
  • EVs are very reliable in theory, meaning that they are mechanically simpler than ICE vehicles. However, some design mistakes could impact their reliability in practice.
  • There are many potential points of failure for EVs, including thousands of battery cells, electrical connections, circuit boards, software, and more. All of these could potentially fail as the vehicle is used and older.
  • Electric vehicles also have cooling systems, motors, and transmissions, among other parts, that require maintenance and replacement.
  • While EVs have less heat generated than ICE vehicles, they do generate some. Therefore, maintenance of these heating and cooling systems is still necessary.
  • Cars like the Fiat 500e and Stellantis have proven to be very reliable since their powertrains were made by Bosch.
  • Hybrids are often more fuel-efficient and lower in emissions than ICE vehicles. Depending on local electrical grid emissions, they can also be as clean as EVs. However, they are mechanically more complex than EVs, so there is also more that can go wrong.
  • ICE vehicles can be very reliable if they are properly maintained.
  • Toyota makes the only EV that some people would not consider due to its reliability.
  • The Ford Lightning has scheduled software updates, meaning that the owner can avoid trips to the shop.
  • EV motors only have one moving part and are supported by bearings, making them generally simpler than ICE vehicles.
  • Over four years, an EV owner with a car, plus two motorcycles, covered nearly 200,000 miles. Total

"Tesla and Nissan Make the Most Reliable Electric Vehicles - Consumer Reports"

  • Consumer Reports ranks Tesla and Nissan as the most reliable electric vehicles
  • Tesla ranks higher than any other automaker in Consumer Reports’ “owner satisfaction” survey, which polls Tesla owners on various aspects of ownership including performance, comfort, and convenience.
  • Consumer Reports uses two different ratings to measure vehicle reliability: a predicted reliability score and a reliability rating. The predicted reliability score is based on a survey of participants and predicts how much more or less reliable one model will be versus another. The reliability rating is based on the performance of a vehicle across many categories in the survey, including trouble spots, owner satisfaction, and road-test performance.
  • Consumer Reports found many traditional automakers, such as General Motors, are struggling to design and implement electric vehicles to compete with Tesla and Nissan
  • According to the survey, electric vehicles were historically less reliable than gasoline-powered cars due to technology limitations. But consumer trends reveal this trend is changing, and electric cars have become more reliable in the last few years.
  • Tesla Model S owners reported a high number of problems for various systems, including the climate control, suspension system, and brakes.
  • The Model X fared worse in the initial quality survey, with owners reporting problematic features including falcon-wing doors that wouldn’t open or close properly, alignment problems, and extensive bodywork flaws.
  • For the Model 3, Consumer Reports suggests a “wait-and-see” approach, as issues with the vehicle’s braking and touchscreen have made headlines.
  • Tesla’s Autopilot feature is also a concern for many survey respondents, who say the system is “irresponsible and dangerously misleading.”
  • The survey also found that brand reputation and loyalty are significant drivers in electric vehicle purchases. Tesla owners were found to be very satisfied with their vehicles’ performance, and consumer interest in purchasing an electric vehicle is also increasing.
  • Some Reddit users in the comments section of the article argue that while Tesla may have quality issues, their owner satisfaction has been higher than other brands.
  • Other users argue that the survey’s distinction between reliability and quality is moot, as being “in the shop” is still a major inconvenience for vehicle owners.
  • Users commented that Tesla’s perceived quality issues may be overblown, as similar problems can be found in other manufacturers’ vehicles.
  • Some respondents in the comments section also criticized Tesla’s customer service, mentioning long wait times and poor communication.
  • Others argue that Tesla’s user interface and tech features, such as the touchscreen display and over-the-air software updates, make up for any quality or
