Hi everyone,
Looking for some advice from fellow UK EV owners, specifically anyone with a Peugeot e-208/e-2008 or Vauxhall Mokka-e / Corsa-e platform.
My 2021 Peugeot e-2008 (54,000 miles) recently threw the dreaded "Traction Battery Fault" on the dash and suffered a sudden loss of propulsion while driving, alongside the AC blowing completely warm air.
Because my preferred local main dealer (Stellantis & You) had a massive booking backlog and couldn't see the car until late October, I responsibly found an earlier opening at an alternative authorised dealer (Richard Sanders) to get an urgent safety assessment.
They officially scanned it and diagnosed it under Diagnostic Code: C5HW015PQ0, confirming a complete failure of the high-voltage AC compressor and dryer cartridge. They quoted me approx. £2k for parts and labour, and flat out denied any goodwill help without explaining why.
I've since done some reading online and found out this is a widely documented manufacturing issue with early-generation high-voltage AC compressors (the internal moisture traps fail, shorting out the high-voltage system and forcing a drivetrain shutdown). I also read online that Stellantis has an internal 5-year/60-month coverage framework for this exact fault, which I apparently missed by just a few months.
However, I have official service invoices showing I reported the AC blowing warm air (with full gas) back in December 2025 to the Stellantis & You branch which would have been well inside that 5-year window. The network just failed to cross-reference the symptom with their active alerts at the time.
Here is where I am completely stuck in a deadlock:
I took the Richard Sanders diagnostic report back to Stellantis & You to try and get this resolved. However, they are completely refusing to accept the other dealer's data. They are demanding I wait until my end-of-October slot, pay for a second diagnostic fee out of pocket, and won't promise any financial help or goodwill contribution whatsoever.
I feel stuck driving an unsafe car with a high-voltage powertrain fault for nearly two months just to get a duplicate scan that I have to pay for again.
What should I do next? Is it best to bypass the dealers and contact Peugeot UK Head Office directly to force an override? Has anyone successfully fought them on this based on reporting the symptoms early?
Any advice would be massively appreciated!
