Excessive fuel consumption

[AisinW]

It is simply marked up price or consumptions.

Not a chance fuel was siphoned and slim chance the speed was exceeded, as said by Bernard above, the driver would not risk his job. 

I've worked in the motor industry since 2017 and I will tell you, that you had no idea how much fuel you had or the mileage when you let them carry out this work.   

It's staggering how many customers think everyone is out to rip them off.  There are still genuine and honest people around.  Unless you have strict proof before you handed it over to them, then you cannot prove it either way.  

I’m not sure how you can tell me I didn’t know what fuel I had or mileage done when you aren’t in possession of the facts.  I simply asked for possible explanations. I do have evidence of fuel and mileage at start and end of journey confirmed by the salesman, when shown to the service manager it caused him to inspect the vehicle to check for any faults or leaks. 

At no point have I suggested anything spurious happened, I am interested though what may cause excessive consumption, after all we buy hybrids to try to get max mpg.

No doubt there’s plenty of honest genuine employees working in the motor trade. But the trade has a bad reputation and only recently a member posted that he had stuff stolen from his car while it was being valeted in the Toyota dealership.

Was the car driven there and back in "B"?

There was a case a number of years ago when Dashcam or recording was rare, a garage hand collected a supercar for servicing and was rather exuberant.   The owner monitored the car and reported it had been driven at over 100.  The mechanic lost his job.

Now, even bottom range Toyota have accessible analytics.

It’s a 2l, no B function, there are paddle shifts with S function but I don’t use them

The analytics didn’t record, this is true for 3 journeys they did of 160+ miles each time, but analytics work every time I drive it

Did the delivery driver use them?

I don’t know, not sure what using them would do to fuel consumption, it’s just simulated gears, I guess it may force over revving but doubt it would make it accelerate faster

53 years ago one of my first jobs, before I got into building, was at a Triumph/Jaguar dealer, removing the protective wax from new car bodywork with a hot water and detergent lance.

These were pretty expensive cars in the day, with XJ6,Stags and so on.

The level of respect shown to customer's car's was abysmal to the best of my memory.

There was a steep ramp from basement level in the steamy depths where I worked, up to the service and showroom level.

The cars got thrashed up that ramp with squealing wheels and revved out engines.

Maybe some of the dealer employees treat cars with respect now, but human nature does not change much.

Obviously Privacy Mode engaged.  Before I got Toyotas I used a standalone satnav.  I didn't have WiFi but it did record the routes and the Dashcam recorded the trip.

Unfortunately many will disconnect satnav and select privacy.

I’m unaware of any privacy mode in the analytics. I did have a Dashcam but the driver pulled the power lead out

It's been some years since I've tried it out (on an Auris, and just out of curiosity to see what it did) but, isn't there a 'maintenance mode' that the Corolla can be put into? 

I seem to remember that this caused the hybrid Auris engine to run continuously, even when the car was stationary. Would this have been used by the garage to assist fault-finding? 

It could certainly foul up the fuel consumption figures if it was left engaged for long enough. 

Maybe I've remembered wrong!

They simulate gears, but also increase engine braking as the B mode does. In B the engine runs pretty much constantly, although in theory it is not using any fuel as it is just pumping air to help slow the car down. I have no idea whether this could account for the excess fuel consumption, but the car would not be running as designed for max economy. An interesting puzzle.

I am not sure any of these like B mode, sport gear change or maintenance mode can lead to 25mpg consumption. Cold weather, bad road conditions or trashing it while driving , nothing really can double the fuel consumption in these cars.
My theory here is very likely a miscalculation.
Fuel in the tank will show full on the dashboard while there might be 5-6 litres less, you know we had discussed in other topics about the fuel gauge moving one bar down after 60-110 miles drive depending on the car.
So if the car had actual 5-6 litres of petrol less than what OP uses for his calculations this can off set the numbers. 
Another reason can be disconnecting of the 12v Battery for some reason, the ecu reset , something that will reset the daily trip and then the actual mileage will be false and lead to miscalculation. 
Around 15mpg is the max you can get down of the regular fuel consumption if any circumstances has changed, like bad driving conditions, poor driving style, cold weather, maintenance mode etc.  

A question to the OP, have you checked the average fuel consumption on the dash after the car was returned to you, if yes what were the numbers? 
Thanks

The car had 45 average on return with the driver who was the salesman reporting he thought he got about 55 as he knew about the previous journey. The average had been reset by me prior to the first trip. 
When I handed it over to the first driver I’d filled up and knew the small mileage I’d done and how far he was going, confirmed by app and talking to the salesman who inspected it and check the fuel, so I do think I have pretty good figures, there should’ve been 40% fuel but there was 6% also reflected in the dash which is the normal I’d get, I’ve had 3 new Toyota’s in the last 4 years so very familiar with them. 
Without questioning the original driver I’m not sure the mystery can be solved. 
I’m not getting 44-55 mostly short town journeys and will try longer asap, readings on fuel are as expected now I’m driving it north on the app and dashboard, at next fill up I’ll manually calculate mpg too

No worries, if you think you were accurate with the fuel inside the vehicle.  I would be staggered to find that was the actual consumption from the car.  Without any evidence or proof, it's definitely not accurate.  Unless there's some major fault with your car and it's now reporting similar MPG since its return.

[simond64]

The 2 fill ups I’ve calculated myself from full tanks, 48 and 47.6mpg, mostly in town though with a little up to 40-60mph, driven carefully, I haven’t done motorway yet. 
I’ve found in previous new Toyota’s the performance gets better after 2-3k. So far though, there 2022 2.0 hb did better, this one is also 2.0 but TS
