Bought £10k car with smoke from exhaust and poor MPG

Borgy

I went to a well know dealership and seen a 2 year old Nissan Juke petrol. Car looked like new, 15k on clock, tested it all seemed ok.
Paid the £9500 as a deal, but then found when the car gets to temp after a run on the motorway I get smoke from the exhaust and my mpg showing just 30 mpg average, yet book says 40-50mpg.

I took video of the smoke after car was running for 5-10 mins.

Some days the smoke is up and down can be little or like this video Shows.

I thought Nissan had replaced the engine in one of your other threads

The video titled,
Nissan juke condensation from exhaust



Its condensation, from the exhaust.

And my book says "up to 71mpg" but I NEVER achieve that.

Yes correct this video was taken after a new engine fitted. The first week had no smoke at all, then started like before. RAC came out and said best to go back to Nissan. They had it two days but never took it in the garage only started engine outside and did a visual check so thought was ok!.

Sure mpg don't expect as book, but I bought car and average was 23mpg over a 3 week period. Now with brand new engine average over 4 week period is 30mpg. For a 1.2 petrol?

My GF/ex GF has one of these and has had it from new, my sister also and my friends Mum, to name 3, along with the reviews I'd say you are getting around the correct mpg for the car (high 20s low 30s) around town.
I had use of a Polo bluemotion and I put £13 of petrol in for the same driving journeys as my own car which would use £15.

The quoted mpg for cars are from a standardised test pattern and unlikely to be matched in the real world driving especially for smaller low power engines.

Submitted average by owners on Honestjohn site is 33mpg, lowest is high 20s.

Small cc and turbo does not always mean high mpg. Our 0.9t 90bhp had worse mpg than our 1.5 110 bhp normally aspirated engine.

If it looks and smells "steamy" or like water then yes its condensation. If it was blue it would be burning oil.

The issue being that the Nissan dealer will be being told by Nissan UK what the "parameters of acceptability" are and that may well fall within it by their "loose" terms.

We had a not dissimilar issue with my dads Ibiza 1.4 petrol. It rattled. Noticably. Dealer checked it and said it was within "normal parameters". How i ultimately got them to deal with it was i said "right, lets get an identical car park it beside my dads and start and run them and see if they sound the same". When it was clearly louder and rattling i said "now do you think that sounds normal and would you accept that if it was your car?" They agreed it wasnt and they escalated it to Seat who replaced the engine. Of interest, the next engine had to be replaced also as it hadnt been built correctly and was leaking water internally, so dont let them palm you off saying it must be ok as its a new engine.

I would go for the "lets compare two identical cars and then we'll see if mine is normal".

If that doesnt work, escalate to Nissan UK.

If that doesnt work, get an independent AA inspection, and send the outcome of it to the dealer with a Letter Before Action stating you will have a third party complete the repairs / replacement of the engine and take them to court for the costs.

I've passed a couple of cars in the last week which have had smoke coming out; the smell of burning is quite intense; if it was that, you would know it!

MPG as said first was 23mpg. That was a software issue which now is over the 30mpg. The smoke is more condensation but has mix of oil from exhaust and drips on the floor, when it was as bad on video listed the weather was dry and temp outside about 14c.
RAC still feel it's no right. I have checked same cars in 2 garages and some have condensation and some none after warm up. Sure with combustion Of fuel you will get some and depends on fuel type.
No water in exhaust. No coolant loss.
I have the ombudsmen dealing with it as garage refused refund within 30day rejection.
After new engine left at garage for 5 weeks but they still refuse to take back. Offer me FREE services for 2 years. FREE mots for 2 years, now I want in writing after I collected car they don't want to give!! Will not reply to calls or emails, staff say it's not down to them it's head office.

You could look on the bright side. It might mean you don't have a Juke for too long......
