Are Teslas giving EV's a bad name as they are being touted that they are less reliable than ICE cars. While I'm not sure how this conclusion was arrived at, I heard in a radio discussion involving aspects of the cost of emission reduction, one had to drive 80000Kms before one reached the breakeven point over a ICE vehicle.
Motor Mouth: Dragged down by Tesla, EVs least reliable cars on British roads
EVs are almost twice as likely to have serious problems as gas-powered cars, according to a survey by U.K. website ‘Which?’

One of the benefits of switching to electric propulsion, say the experts, is that their fewer rotating mechanical bits result in fewer breakdowns. That’s the theory, at least.
In reality, a recent study in the United Kingdom by consumer website
Which? says that electric vehicles are actually
less reliable than their petrol-powered (that’s “gasoline” in British) competitors. In fact, according to the respondents, EVs are almost twice as likely to develop a serious fault — 31 per cent for electrics, versus just 19 per cent for petrol power — as conventional cars.
Not only that, the typical repair takes longer for cars powered by batteries — five days versus three — than for those swinging pistons. Worse yet, the other supposed superiority of EVs — that they can be more easily and quickly repaired with over-the-air updates — seems to take a hit in the survey of 48,034 car owners (2,184 of which owned pure electrics)
According to the survey, the number one glitch needing attention in EVs was software-related. Married with the fact that, as I said, EVs were also off the road for a survey-topping average of 5.1 days every year, it’d seem there’s little evidence yet of a tangible benefit to OTA updates and repairs.
Indeed, that apparent anomaly seems to be perplexing some experts, James Gibson, the head of technical information for England’s Royal Automobile Club, telling
thismoney.co.uk that “There is no question there are fewer moving parts with electric cars,
” but noting “the software running them is more complex, which has the potential to cause some issues.
Perhaps more surprising is that Tesla, the face of EVs and the manufacturer with the most experience building electrics, is the least reliable of the lot. According to the
Which? survey, a whopping 39 per cent of Teslas up to four years old had at least one fault, and one in 20 had had a serious no-start situation or a breakdown serious enough that it had to be taken off the road.
On the other hand, owners of Kia’s e-Niro reported their cars to be the most reliable of electrics, with just six per cent of owners reporting a fault of any kind; and just one in a hundred saying their vehicle failed to start or broke down. That said, e-Niro owners who did report a serious breakdown had to wait an average of eight-and-a-half days for a repair, almost three times as long as the three-and-a-half days required to get a Tesla back on the road. Nonetheless, it’s worth noting that while the Kia was the most reliable compact SUV in the segment — triumphing over its gas, diesel, and hybrid competitors — Teslas were the least reliable of all electrics.

Making matters worse is that, as in so many other jurisdictions, Tesla is the dominant player in England’s EV segment, the Model Y and 3 accounting for almost 25 per cent of the 10,417 BEVs sold in February 2022. Extrapolate the numbers through the entire study and Tesla’s fallibility may well be a large part of the reason that the
Which? study found that EVs are the least reliable cars on British roads.
Conventional gasoline-powered cars, however, are
not the most reliable vehicles on the road. That honour would seem to be held by conventional — not plug-in —
hybrids. According to the survey, just 17.3 per cent of hybrids had even a single fault, and their 3.9 days off the road and 5.6-per-cent breakdown rate was superior to EVs as well. At least part of that advantage is explained by the fact that Toyota, the automaker with the most enviable reliability record in the entire industry, enjoys, according to
Electrek,
. Marrying all the survey’s data with market share numbers seems to imply it matters less
what you drive than who makes it
Indeed, according to
Which? cars editor Adrian Porter, “Year on year, Tesla comes up as one the most fault-prone, unreliable car manufacturers thanks to feedback from current owners,” adding that it seems almost “counterintuitive” that electric cars, with so few moving parts, are the most fault-prone in the survey, while full hybrids, “which have two systems of propulsion, are the most dependable.”
This seeming fallibility, however, doesn’t seem to dampen Tesla fans’ ardour, however.
Consumer Reports, for instance, notes that the Tesla Model S and X — along with Porsche’s Taycan and the Jaguar I-Pace — scored second-last on its five-point reliability scale, while the magazine considers the Chevrolet Bolt one of the most reliable vehicles on the road regardless of powertrain. (One guess as to which car garners all the headlines and sales.) Other surveys reinforce this seeming dichotomy, a J.D. Power report noting that “while Tesla is seen to have poor quality,
, indicating their willingness to overlook quality problems.”
In other words, the badge displayed on the trunk is more important than the quality of what’s under its hoo
And, as the U.K. data indicates, while the propulsion systems — essentially the electric motors and batteries — are admirably bullet-proof, other aspects of basic construction such as suspension and steering (2018 to 2021 Model 3s seem particularly susceptible to upper A-arm breakdown) still seem to trouble the Silicon Valley upstart.
“The Tesla Model 3 has a reputation for prestige, but the quality of finish… is unworthy of a car selling for $60,000 or more,” concluded
Protégez-Vous. That established automakers have a major advantage in this regard also emulates the British data, the most reliable plug-in in
Protégez-Vous’ study being — drum roll, please — Toyota’s Prius Prime. And mirroring virtually every study of inter-brand reliability,
Protégez-Vous concludes that “Tesla disappoints, Toyota holds up.”]
