Another reason not to own a EV

[Hunters Edge]

Again I think it has more to do with the individual design etc. Maybe it's a GM thing but a guy I work with his GMC has maybe 50,000 miles on it and the transmission ate itself. Toyota uses them and I know a mechanic who inspects my older car and he drives a Prius and he says it's the most dependable vehicle he's come across and he recommends them to everybody. So I don't think again it is the technology that's like saying engines are unreliable because the pinto was a sled or the Vega used to shoot spark plugs out of the head or whatever it did

I still disagree. Many including yourself is limiting million of vehicles to what or who you know. Similar to study or poll only using a select group rather than either a larger pool or different demographics. I will agree that any one having an issue with a manufacturer should diligently look into how many are reporting the same issue with NHSTA .

They are all having issues and recalls. I think Ford escalated this when they stopped manufacturing the parts and started outsourcing them. Only reason I say this the timeline coincides with this particular issue and I have a hard time thinking it's coincidence.

In a nutshell in the end they are not saving money or creating and maintaining a customer base with increased recalls and warranty issues. So in the end it's costing them so much more or a very costly error.

Agreed but that's a Ford problem not an EV or ECVT issue. Again, Toyota doesn't have a problem with ECVT's and a BEV ( VAST majority anyway) don't shift at all . No rational person who knows cars would argue the same company that can make a transmission that shifts through 8 gears dependable can't make a single speed box that never shifts at least equally dependable.
That point is irrelevant anyway as was your post because you were using the supposed unreliability of ECVT's as a reason not to get an EV. But EVs don't use ECVT's.......

No we got off topic and wanted to correct what was posted. Unfortunately majority of us, including myself can be influenced by perception. That sadly is hard to change even with documentation showing or proving the issue. It's a human trait, might be why for years many believed the earth was flat.

...Here is another article, unfortunately it suggests the CVT are more expensive to repair.

https://www.caranddriver.com/research/a31517125/cvt-transmission-vs-automatic-quick-guide/

let me type it a little slower for you - eCVT is nothing like a CVT, I repeat eCVT is nothing like a CVT. Why do you keep citing stuff about CVTs? A CVT uses pullies that change shape causing a steel belt to spin the opposite pully a variable rates where as an eCVT uses a sun and planetary gears along with 2 electric Motor Generators to achieve the variable speeds on the drive side of the transmission. there is absolutely no shifting gears and reverse is accomplished by reversing Motor Generator #2 (always electric).

Here is my work;

Modes

• “Ready” On (Vehicle Stopped)
• If the High Voltage Battery (HVB) is charged enough the “Ready” light will be on but the Internal Combustion Engine (ICE) will not start.
• Charging While Stopped
• If the HVB does not have the desired charge Motor Generator 1 (MG1) will start the ICE, and while powered by the crank shaft MG1 will charge the HVB.
• The ICE will cycle on/ off as needed as long as it is “Ready”
• Starting Off with Low Load
• If the HVB charge is high enough Motor Generator 2 (MG2) will start to propel the vehicle (without the ICE).
• Depending on the load and the HVB charge state you will stay in electric mode until one of these other two conditions change requiring the ICE to start.
• Starting Off with Low HVB Charge
• MG1 will start the ICE.
• MG1 will start charging the HVB and power MG2.
• MG2 and the ICE will propel the vehicle.
• Constant Speed Cruising
• MG1 (using the Sun and Planetary Gears) will move at a speed that will allow the ICE RPM to be the most efficient but keeping the wheels rotating at the required speed.
• The rotation of MG1 in relation to the rotation of the ICE crank shaft controls (via the Sun and Planetary Gears) will cause the ‘under drive’, ‘direct drive’, and ‘overdrive’ gear ratios of the propulsion.
• If MG1 rotates faster than the crank shaft the vehicle’s wheels move slower (under drive).
• If MG1 rotates at the same speed as the crank shaft the vehicle’s wheels are at the same speed (direct drive).
• If MG1 rotates slower than (or in the opposite direction) to the crank shaft the vehicle’s wheels go faster (over drive).
• Constant Speed Cruising with the HVB in a Low State of Charge
• The ICE speeds up to spin MG1 faster. MG1 charges the HVB. MG2 (powered by MG1) and the ICE propel the vehicle.
• Full Throttle Acceleration
• MG2 (using power from the HVB) and the ICE both propel vehicle while MG1 controls the gear ratio.
• Deceleration
• MG2 switches to a generator and helps recharge the HVB and causes regenerative breaking.
• Reverse
• MG2 runs backwards to propel the truck backwards - powered by the HVB (if sufficiently charged) or the ICE (turning MG1 a generator).

Note: The 12V battery under the back seat is used to run accessories and is charged by the HVB using an inverter - there is no alternator!

ECVT stands for Electronically Controlled Continuously Variable Transmission. It's a modern transmission system that's often found in hybrid vehicles and is known for its smooth gear transitions and improved fuel economy.

ECVTs are different from conventional Continuously Variable Transmissions (CVTs) because they use:

• Infinite gear ratios
• Planetary gears
• An electrical system to convert the power generated by the internal combustion engine
• Two electric motors connected to the car battery

ECVTs are also compact and lightweight, and can improve the fuel economy of small cars with a torque converter automatic transmission (AT). For example, the Subaru ECVT improved the fuel economy of the Justy ECVT by 15 to 20%.

CVT stands for continuously variable transmission, and it's a type of automatic transmission that doesn't have gears like a traditional transmission. CVTs use two pulleys and a chain or belt that automatically adjusts to your speed, allowing for a seamless transfer of power between the engine and transmission. This means there's no need to manually change gears, which can lead to better fuel efficiency and make for easier long-distance drives. CVTs are also lighter and have fewer parts than traditional transmissions.

Now understand the difference and the similarities. ECVT Electric Continuously Variable Transmission and Continuously Variable Transmission. They are both Continuously Variable Transmission.

Just for the record when I suggested data. It was data showing the difference in longevity.

I was geeking out learning about it. It’s truly a marvel of ingenuity. The only similarity an eCVT has with a CVT is it achieves the same task (using a totally different mythology) therefore the engineers/ designers gave it a similar name, but that's where any similarity ends.
