Used car fault - OK to reject?

[Dracoro]

Have bought a used car from dealer (2017 car with 40k on clock no not and old banger!) less than 4 weeks ago.

Everything is OK apart from a hum at above 40mph which I reported a few days after purchasing car (having driven it for a bit, have noticed hum).

Dealer told me to take it to their local garage, which I did, but they could "not find a fault or hear hum".......

Anyway, noise is definitely present.

So I took it to local garage (not same place as above) and they have diagnosed as rear wheel bearing needs replacement.

Selling dealer salesman is speaking to his boss and will get back to me......

I don't want to reject car, just have it fixed. Does a noisy wheel bearing class as a fault that they must fix?

However should they not play ball, what are my rights? I understand as bought < 30 days ago, I can reject (don't want to reject, just have it fixed) under CRA?

Hopefully they will just pay for fix and everyone's happy......

Thanks, however looking to find out if wheel bearing is sufficient grounds to reject or not.

I don't want to reject, however if it is grounds then that could be the push to ensure selling dealer gets it fixed.

Thanks for those that actually read my posts (even tho title is a little misleading, my bad. As posted do not want to reject car, just wanted to know where I stood etc if seller wanted to play silly (they’ve been fine).

Saw tooth issue - is this something noticeable on tyres as can’t feel/see anything odd. Tyres aren’t old all all good (Michelin pilot sport 5 I think). Swapped wheels back/side but don’t think that made a difference to hum sound.

40k miles seems low for a rear wheel bearing

Has the Haldex been serviced?

Would Haldex service (or lack of) be related to issue as described?

All tyres (MPS5s all round) have year stamp of 0423 and one 4923 and all appear to have loads of tread. Also, I can’t see or feel anything untoward (I.e. edging like a saw or otherwise)….

Although steering/handling all seems good, could alignment be cause?

Hum appears at 44mph and goes away at 48. Also appears at 67 and goes away at 71… which sounds frequency based?…

100% the tyres, you don't need to look for anything other than wear, unless the tyres are fairly new, you'll get a hum. If this is the only fault you have with the car, you'd be nuts to reject, other than the fact that 23k for a 17 plate R seems pricey.

If it bothers you that much but you love the car, replace the tyres yourself as you the dealer will not replace road legal tyres that hum a little.

The tyres are fairly new (0423 markings on 3 and 4923 on another) so barely a year old and loads of tread. As I have said a few times, I don't want to reject just have it sorted.

As for price, for a low mileage 7.5R (67 plate) with sunroof/DCC/Leather/Pro navi/19 Spielbergs/etc., it was about the going rate, loads of lower spec ones (cheaper) of course

Did you put the rear tyres on the front or just switch side to side ?

Swapped left rear to left front.

Then swapped left rear to right rear. i.e. only one not changes is front right. Which I may do later and see if makes a difference..

So far, changing wheel location hasn't changed anything...

[Dracoro]

I did not notice any play etc. in wheels.

Am going to swap the wheels round that hasn't been changes (so all wheels are on opposite side AND axle to what they were originally) to see if noise the same.

Note, garage noticed sound on test drive and did stethoscope test to identify wheel bearing. I suppose it's possible there was and issue with bearing AND with tyres I suppose.......

It might not be the issue of course but since your symptoms are the same as 99% of others that suffer stepped or sawtoothing tyres on these cars , Occums razor applies

Either way is almost certainly not a wheel bearing so if you love the car its probably worth putting a fresh set of tyres on and getting the geometry done

There's no harsh edging ("saw toothing") on the tyres, either visually or to feel, that I can detect. As I say, the tyres are not old and loads of tread (7mm). One tyre is newer than the others (4923 rather than 4023).

If it's definitely tyres, then will prob wear them out (that will take a while as not a high mileage driver these days!) and then see if replacement/alignment helps or not. They're not cheap tyres and no point replacing all if not all have any issues.....

[Dracoro]

Further note/update, all wheels are now on opposite corner to what they were originally (and I tested changing just 2 wheels at a time) and noise still the same.

[Dracoro]

Sounds exactly the same no matter which corner a wheel is put on. Sounds like from left side somewhere. Can't really tell if rear or front.

[Dracoro]

Note I have put the spare (space saver) wheel on both front and rear (nearside) and same noise regardless.

So whilst it “might” be tyres, there’s no way to identify which one is culprit given sound is same not matter which corner each tyre is put on.

Anyway, in on Monday for further check…
