Hi all, I have joined you all as I am really not sure what to do about my totally faulty 2025 SQ5

It has had drive train faults

Air suspension fault, not fixed by software update but needed replacing

Cameras not working so front collision detection off, high beam assist off etc

Now it's back in Audi with Hold brake fault. This was a red stop the car and don't drive message.

The dealership can't match the fault codes that the VW breakdown guy logged and said it needed new brake servo unit. They are testing now but are happy to let me have it back with this safety fault. Any ideas what to do? The bar is set so low by Audi they don't feel these faults are worrying. 

I promise I will reply to anyone who answers me. 

 

A 2025 car should still be under guarantee. If the dealer can not fix it, reject the car and ask for a refund.

I’m going through a similar process with my 2025 Audi Q5 TDI rejecting the car, it failed to start and required Audi assistance, logged 124 fault codes, too many inherent defects rejecting vehicle.

Template letter if required 

I am writing to formally reject my vehicle under the Consumer Rights Act 2015.

Vehicle details
• Make/Model: Audi
• Registration: 
• Purchase date: 
• Purchase method: 
• Current mileage: approximately 

Since delivery, the vehicle has suffered from an engine management fault, evidenced by warning lights illuminating on the dashboard. This fault has caused serious concern regarding the vehicle’s reliability, safety, and the risk of consequential engine damage.

I first reported this issue to ……………and the vehicle attended the workshop on ………list all………..for investigation and repair. Despite this attempted repair, the fault has not been resolved.

I have since been informed that the vehicle is now booked in again for further investigation on …………date……….. Given that this fault was first reported in …………date ………… and remains unresolved several months later, I do not consider this to be a reasonable or acceptable timeframe for resolution.

I am also aware that this same fault is widely reported by other 2025 Audi Q5 owners across multiple independent automotive forums and owner groups, indicating that this is likely an inherent or systemic defect, rather than an isolated issue affecting my vehicle alone.

As this fault has arisen well within the first six months of ownership, it is legally presumed to have been present at the time of supply. In light of the failed repair attempt, the prolonged delay, and the ongoing nature of the defect, the vehicle is not of satisfactory quality and does not meet the requirements of Sections 9, 19, and 24 of the Consumer Rights Act 2015.

I am therefore exercising my final right to reject the vehicle and request a full refund, including any associated fees, in accordance with my statutory rights.

Please also note that while displaying engine management warning lights, the vehicle would fail an MOT inspection, and I am unwilling to continue using a vehicle in this condition or consent to further repair attempts.

Please provide written confirmation within 14 days of:

1. Acceptance of this rejection

2. Arrangements for the return of the vehicle

3. Timescales for full reimbursement

Please ensure that all future correspondence is conducted in writing.

Many thanks indeed Andrew, and I hope this goes to plan, and with a prompt and successful outcome.

Regards,

Gareth.

I hope this is how I reply to you. The letter is very helpful but the faults have all been different, apart from air suspension, which they said was fixed with a software update but was not. This had to be replaced. 

The car was bought on 21st June so I'm beyond 6 months, just. Still worth pressing to reject I think. The dealer would be happy for me to drive it until the fault code is back. As a lone female I am certainly not going to drive it and get stranded.

I found that the dealership Synter are protecting the brand, I’m now considering legal action through my house hold insurance policy. I would also suggest reporting to citizens advice, if enough people do same, trading standards will investigate.

good luck

I don't blame you Paula for being reluctant to drive it. If you are still hesitant about rejecting the car contact a solicitor for advice, but don't leave it too long. Driving the car with known faults might be construed as accepting them.

Hi Sytner are a particularly evil dealership to deal with whatever brand you are buying, my niece bought a brand new Mini from them and had multiple faults with it in the first year, so we had a years ownership but worked out the car only functioned properly for four months even the dealers were embarrassed when the courtesy car flaked out on the M25 in the middle lane seized solid no oil apparently, they wanted to trailer the car back to the dealers but my brother in law hijacked it and held it at his mates the recovery owner until they gave her a refund otherwise he would publish the findings of an engineers report that he had commissioned £400 on a two year old courtesy car, after that they keep on messaging Charlotte with all sorts of promises of upgrades and free gifts if she bought from them again, so she sent them a new personal email address to send all promises to ,[email protected], the moral being don't let up these shysters.

Thanks to you all for your help and non biased help. I will not accept driving it. I did say I would ask them to sign a declaration that it is safe to drive, the conversation then switched to him talking to the new car manager. Tomorrow I hope we can move things fwd. I will let you know

I’ve now received confirmation that my vehicle rejection has been accepted, and I’m currently awaiting further details on the next steps.

As we purchased the car outright, it’ll be interesting to see how this progresses and what the final resolution looks like.

For context, the car is a Q5 Edition 1 TDI in Daytona Grey, with panoramic roof, air suspension, and a 5-year Audi warranty. We secured it with a very strong discount at the time of purchase.

Depending on how things are valued during the process, it may make more sense to sell it privately.

It’s also worth noting the car has had:

• Stage 1 paint correction

• Ceramic coating

• Front and rear dash cams professionally installed

• Private registration plate

I’ll update the thread once I know more.

I will be very interested to know how that goes. My SQ5 Edition 1 2025 car is still with Audi after 3 weeks. We are seeking legal advice after going through Audi UK  and now VW finance. Annoying it's on a pcp but with a hefty deposit from the sale of my car. We want a replacement.

Audi uk are a waste of time, I ended dealing with the ceo department and they could not even answer simple questions. Just fob you off. Good luck
