I am keeping a journal Word document regarding our 'Elite' Hybrid 4.
Grandland Hybrid 4 ordered from Aston Vauxhall in Feb 2020 and delivered to my door 10 July 2020.
Update: - Thursday 20 Aug 2020, 10 AM appointment at Picador Chandlers Ford (Southampton).
On the way to Picador, I engaged cruise control and got another Warning Chime “Cruise control fault” (the gremlins are active today)
Thursday 20 Aug 2020 at 1709 I get an email saying ‘ready for collection’. I collect 21st and I am told it was a CAN bus fault.
A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other's applications without a host computer.
https://en.wikipedia.org/wiki/CAN_bus
My email to Picador: -
Thank you so much Ben and perhaps John, for sorting our Hybrid 4 so swiftly.
It's a shame we are now 'waiting for the shoe to drop'
Our Citroen C5 allowed us to fully load for a family Christmas in Cheshire, before announcing "suspension fault, do not exceed 55 mph"
I emailed Wyatt Winchester for an appointment. That was 2010. I am still waiting for a reply, but the fault went away!

At 146 miles 1630 Saturday 15/8/2020
Warning Chime: “Electric Traction System Fault, Speed is limited, repair the vehicle”
I pressed the Black Button (next to the SOS Button) to get assistance. A lady responded quite quickly and put me through to, what I imagine was, the duty recovery man.
He advised me to drive to my local Vauxhall dealer, so long as there was no smoke, or other bad symptoms.
Here is a link to my you tube channel with a short video explaining the fault: -


19 Aug I sent a ‘test’ email to Picador and kept a screen capture to enable them to analyse where these emails go.

18 Aug I phoned Picador; they don't read emails!
I am booked in for an inspection on Thursday AM.

The whole 'My Vauxhall' email system seems to land in an inbox no one is aware of.

I used ‘My Vauxhall’ to email Picador Chandlers Ford to report my serious Electric Traction Fault. I emailed again to explain that the Power Flow screen showed the front wheels being driven by the front electric motor. (Should be rear wheel drive) and entered the link to my you tube.
As of Tuesday, 1021, have not yet received any response.

Email to Aston (the supplier of the car) I am obliged to keep Aston in the loop, so emailed them with an update but hope to receive an appointment to visit Picador.
Monday 17 Aug at 1430, I phoned Vauxhall Customer Care Enquiries: 0800 026 0034
Becky gave me a case number 319 573 64 regarding my Electric Traction Fault and the lack of response to 3-emails from me to Picador Chandlers Ford.
She said she would contact Picador.
Monday 1630 I returned a call to David Thomson of Aston. He suggested I get back to Aston head office if I had no response from Picador by 10AM today Tues 18 Aug 2020.

Email to Aston 13 July 2020
Hi Katie,
I have registered Pam with 'My Vauxhall' but you can see from the attached screen capture that ownership needs verifying.
Are you able to fix that?
I wish I had seen a price guide like the attached .pdf.
When I ordered a £38k car, it never occurred to me that the spec would be lower than my Mokka at half the price.
I now have to arrange for the fitment of a reversing camera at my local Picador Vauxhall garage.
Add this disappointment to the shock of a VED Hike based on the list price of over £40k.
Elite Nav Hybrid4 1.6 (300hp) Direct Injection Turbo/Electric AWD auto 5d. Years 2-6 £465.00 PA.
I have had a few tears from Pam.
The new car is as stressful as a new computer.
I attach a few screen-captures to illustrate the problems.
One needs to be an 'IT' expert to navigate the options.
Add to the above, the 'My Vauxhall' app on our Android phones.
Would you believe, the last instruction on the phone was to make four journeys of at least 20-minutes to complete our registration of some e-remote feature.
I hope my feedback is considered constructive and not just a whine.
I have spent £69 on real-time traffic navigation support for one year.
I can tell you the 3-pin charger is better than hoped for. The car charges at 8-miles/hour. With a range of, say, 32-miles, that is only 4-hours for a complete charge. I measured the load on the socket outlet at 1800 to 2000 Watts.
We have only been on one 6-mile trip, so too early to know the car. We did enjoy a bike ride and found it less stressful than cars.
I am still disappointed that Vauxhall do not offer a download of the user manual in .pdf form.
The Vauxhall website made it impossible to configure a car purchase and discover the price. The page would not load and kept churning(unresponsive).
I had to go to a Peugeot site to get a price for the 7kW charging car.
The Pod-point 'free' charger was the first of our disappointments. (Pod-point charged an additional £359.00 installation fee for the ‘Free’ Vauxhall 7.4 kW home charger). Later refunded.
My application to buy was back in February, before Vauxhall had got their act together. Information was in short supply.
The pleasure of buying our Mokka in 2016 was not repeated when buying a Hybrid 4 in 2020.
The main reason for success in 2016 was that Aston ordered the Mokka with a spare wheel and reversing camera. The customer did not have to choose from a lot of options.

I asked for a quote from Picador: -
Reversing camera not possible, but an after-market specialist was recommended and he quoted £600.
I did it myself for £280: -
https://www.in-car-install.co.uk/catalo ... =grandland

Detachable tow bar £1175.95
No fixed option for PHEV

Roof bars £253.65

Space saver wheel and tyre £180.00

Tool kit inc. jack £142.09

We kindly refer you to THULE for your roof box enquiry as we are not able to confirm if the wheel will fit inside.

(I subsequently sourced all except the tow-bar from eBay)
No one, other than Vauxhall, wants to quote for fitting a tow-bar. My Mokka tow-bar cost £777 (fitted by Vauxhall, or was it?).
I cannot justify £1175 just to carry two bikes, I'll have to use the Mokka for that job.

Thanks for the detailed journal post Moss5

I may follow suit, if I get the car back

Had same issue on traction system.

At 30 miles 10pm wednesday 30/10/2020
Warning Chime: “Electric Traction System Fault, Speed is limited, repair the vehicle”
Car taken into dealer, but now sitting there as no trained technicians for ev cars available to look at. Most ev car training was cancelled due to covid (covid is to blame for most things now)

Just wondered if you knew the diagnosis and fix for this so I can tell dealer, how to get my wheels running again? Would be much appreciated

I think cards are held close to the chest when talking to your Vauxhall dealer.
Luckily, my local workshop (Picador, Chandlers Ford Southampton) has one trained Hybrid technician.
The Can Bus fault was cleared, but no explanation was given. I suspect computer gremlins are a mystery to us all.
I got the impression that because "no fault found", Picador were not compensated by Vauxhall. So the fault may not be reported to a higher authority.
Since that fault, I have disconnected my £300 reversing camera, to remove it from the fault diagnosis.
I have also had another computer gremlin "Cruise activation denied conditions unsuitable". This message would be legitimate, if I were trying to set cruise at below 25 MPH. I got the same message at 30/40 and 50 MPH.
Picador were quick to give me a repair appointment and rectified the problem by deleting errors through the diagnostic port.
These faults have caused me to lack faith in my Hybrid 4. I only use it for local journeys. When I went on a touring holiday to Hereford, I took our Mokka. Not a good advert for a £40k car.
My experience shows that the best way to book a workshop appointment is via 'My Vauxhall'. I nominate my local dealer as the location and they phone me to say they cannot make the selected appointment date/time that Vauxhall had offered, but offer an alternative.
My early attempts of emailing the local dealer were a waste of time. No-one reads emails, but I did get a response from a phone call.
Somewhere on this forum, you will find contact details for the CEO of Vauxhall and good feedback on their response to a customers problem.
I suggest you ask the CEO where to take your £40k car to be fixed. They should offer to trailer it to the workshop and deliver it to your door, when fixed.

I just joined the forum because of this thread. I have (had) the same issue at least 4 times until now.
Nothing came up on the diagnose, at least nothing they were looking for. Apparently there is a TSB related to this error but it mentions specific P-error codes which were not found in my data dump. So they were going to do a DID (some sort of diagnostic escalation) next time it occurs.

I have discovered the very best teacher with perfect English.
His facebook group may be of interest.

so the diagnose in this case was a faulty current sensor?
interesting to see/hear, but you know this might be totally different to what we have in our car :) who knows....
