We purchased our 3rd car with BMW a Mercedes C220, we took their 3 year Big Assist warranty, which is in fact Warranty 2000, (one of the worst warranty companies on the market) it was sold as trouble free motoring, no unexpected high bills, only genuine parts used etc. this is a lie. after 4000 miles I had a fault with a Nox censor, Big Assist/Warranty 2000 would only cover an aftermarket part that they costed at £130 & half hour labour, (the Mercedes part is over £500) they didn’t cover the cost for the diagnostic to identify the issu or the programming of the censor, that is required. my total bill was over £700 were Big Assist/W 2000 paid £177. I contacted Big Assist/Warranty 2000, who blamed BMW, for wrongly informing me that only genuine parts will be used etc. I contacted BMW who responded with "due to yourself purchasing the vehicle on 18/09/2022 we are unable to assist further with replacement because of the time period since purchase. We don't assist further concerns outside of the first 6 months since purchase, so I apologise for this. The warranty company have based their authorisation on replacement based on an aftermarket or used component. The total authorisation they had given was £177. If you have further questions regarding this matter, I would advise contacting the warranty company directly due to themselves giving the authorisation". BMW sold me a 3-year warranty but after 6 months they take no responsibility, despite being sold as Big Assist Warranty!!!!
