In Last 6 months I had 3 strikes on my SDV6 2012 HSE where the car start to loose acceleration at 130km/h stabilized speed. Like no more gas, then gear box get confused too but then if going faster or if breaking...car recovers and is fine.
No error code what so ever. Gave the car for annual service today to Land Rover and described the issue. Their honest comment was accelerator pedal potentiometer have had some failures and make car to loose acceleration around 130km/hr. So a known problem. Their description fitted the symptoms I experienced. So appointment taken for complete change. In mean time I will make sure I drive faster than 130...

Just thought I would share that.

Good spot abcsworld I imagine this will also
affect the Disco4's using the same engine. 2013 Discovery HSE Luxury - 3.0 SDV6 - Santorini Black
2013 Evoque 5 Door Pure Tech SD4 - Orkney Grey with Panoramic Roof (Mrs E's new baby)

GONE - RRS - 3.0 TDV6 HSE - Santorini (2010)
GONE - RRS - 2.7 TDV6 HSE - Java Black (2007)
GONE - Porsche Boxster S - 3.2 - Black

Ive driven mine at 130 too, but that was on my way to an appointment at 135.

I went faster than 130km on my way to Berlin...all on the autobahn's in the de-restricted bit...car was fantastic. Mike

We cant do that sort of speed in OZ without instant loss of licence But interested in the potentiometer was driving my wife's 3.0SDV6RRS it seemed that at times the accelerator was not connected to the engine. Pressed it down, nothing happened. Pressed further, then a lazy response. SWMBO is reporting some lag when driving/reversing. Wonder if that might be the cause? SWMBO owns this car I get to drive occasionally

Ignore my last post turns out that this was the Gradient control kicking in as car had come down steep drive, A new feature (well new to us ) SWMBO owns this car I get to drive occasionally

My sport sometimes loses acceleration mainly on pulling away at junctions, spasmodic approx every 4/5 weeks, has anyone else experience the same? Sdv6 my 12

Get it booked in at your dealer, there is a TSB out for it, mine has had 2 or 3 gearbox software updates since new.

Thanks Andy i'ii check in for update.

Just had my sdv6 my12 checked a landrover dealer and they said they have adjusted the foot brake switch which often causes power loss when accelerating...this was at Westover at Christchurch...so far it hasn't happened yet but I will post any further results..thanks everyone for your help.

My 2012 had this problelm and when it went in for its 2nd sevice at Hunters Kings Lynn they replaced the foot brake switch as it needs to tell the ECU that it is alright to accelarate.This did seem to cure the problem but i have noticed that the time lag for the ECU to realise that the foot brake has come off and then too allow the motor to acelarate is not as quick as i think it should be and there fore gives the impression that the engine has momenteraly died, but soon picks up.

I have something similar, in that sometimes at junctions it doesn't want to pull away straight away or very slowly, then it catches up to how far you have depressed the accelerator and zooms off at fast speed. Can be a bit of a pain, will have it checked at next service, but have read several reports, even on test report, that it seems to be hesitant to pull away from junctions, or when stopped. Anyone else having a similar problems?  John
