I bought a approved used mercedes 2.5 months ago and it has a problem.

The problem is the car is slowly losing coolant somewhere which isn't visible.

When I took the car in to a main dealer to have it checked as it's still under warranty they couldn;t find any visible leaks but advised me to rebook the car in for further diognestics as they agreed their is a problem somewhere. As I had the car only 2.5 months I decided to take it back to the dealers I bought the car from give them the opportunity to fix it.

I'm wondering if the problem turns out to be major such as head gasket problem or the problem still persits after they say they have repaired it, am I within my rights to ask for replacement car or a refund as it wasn't sold to me as it isn't of satisfactory quality.

If so what the best way to approach this with the dealer.

the car only 1.5 years old with only 11,200 miles on the clock. I paid nearly £25k for it.

under the consumer rights act its their responsibility under 6mts to repair the issue

should they fail

then you can reject the car yes

is this on finance?

Hi Dx,

Thanks for the reply. No the car not on finance but regretting not taking it out on finance now. I dropped the car of to the dealer today .

Is it worth me emailing them about my intention about rejecting the car if it's not fixed first time round or shall I leave it and see what happens.

theres certainly no harm in reminding the of what CRA states.

… And you should put in writing. Put them in no doubt that you are relying on the Act

Rest assured that it's very unlikely to be something serious, surely not a head gasket at 11k miles.

It's probably a loose clip somewhere in the coolant system, or a jumbo bolt slightly leaking.

I usually put the system under pressure and use a "snake" camera (the very thin ones on a semi flexible wire) to find the leak.

Look out for crystalised coolant and you'll find the leak.

Mechanics nowadays don't want to waste time, so they'll tell you it's ok.
