I like to rob the automotive industry of their profits by buying cars as rarely as I possibly can, and service shops by doing the work myself. The flipside is, of course, knowing what to pay attention to. This '25 110 is my first Land Rover vehicle, so, regrettably, I am not familiar with the "family history" and have little idea about what small but important things to keep an eye on - and I'm sure I'll be far off if I look at things I know to be idiosyncratic for other manufacturers' vehicles (like, a ¢50 part that turns into a $500 repair for a window regulator once in a couple of years for a certain European manufacturer to stay unnamed).

So, what are those non-obvious things that must be maintained relentlessly to turn this Defender into a half a million mile vehicle?

PS: Especially as far as the moon dust is concerned. Been a major presence with the Jeep (hasn't turned into a problem because it died young), and so far it looks like this vehicle keeps the same pattern of dust accumulating at seals and eating into the paint.

 

Paradox:

You ask a very interesting question.

Considering the youthful age of the new Defender design, I am not sure anyone knows the answer to your question. However, as one whose 2020 Defender 110 S is at 75K miles, and having owned an early design Evoque previously (with the same engine), and transitionary generation 2011 and 2013 LR4s (with the same transmission), I can take a guess at an answer, which is a short one with two main ideas:

1.) maintain and utilize deep financial and personal time pockets to keep up with recurring maintenance costs and vehicle failures. Remain alert to falling behind the fixing of small items (mostly electronic) which can snowball into a load of personal dissatisfaction with the vehicle.

2.) do not buy into the manufacturer's recommendations of extended service times between changing fluids and replacing other regular wear items. These times, many believe, are set to serve the lease market, which I think is the primary method through which modern JLR products reach the marketplace.

I am most interested to read the thoughts from others on this forum.

Enjoy !

 

My 2c

Rear shocks will fail if you're doing any sort of corrugations. I think I have shock and/or bushing issues on 3 corners. possibly 4. Both rear shocks are failed as far as I can tell. Had one replaced under warranty and it lasted 11 months.

Small turbos on these with lots of associated heat and oil cooking. New oil every 21k miles is bananas IMO. I swap every 10k but I'll probably shorten this to 7500 as my mileage is ticking up.

Exhaust manifold bolts may be a weak point. Some worrying posts appearing.

Replace the diff and t-case oils more frequently than the schedule. These are very expensive elements. An ounce of prevention yada yada yada. Especially the rear e-diff.

Brakes are good on these. I've swapped rear pads so far. Fronts are going strong. 72k miles.

Transmission fluid change. I don't plan to wait till 105k miles. Plan is less than 75k. In line with ZF's recommendation.

 

The Evoque didn’t have the Ingenium engine until 2018. 2011-2017 had a Ford EcoBoost engine. The LR4 didn’t use the ZF 8HP 8-speed transmission until 2014 when they dropped the 5.0 V8 for the 3.0 supercharged V6. 2010-2013 LR4 used the ZF 6HP 6-speed transmission. However, maintenance is the same for the 6HP and 8HP.

Since the engines are completely different, you can’t follow the same intervals, and the Ingenium is nowhere near as problematic as the EcoBoost engines used in the early Evoques and early Discovery Sports.

 

Have they solved the design issue of the persistent coolant leak in the V8s? The hose rubbing against an edge near the connection point at the engine block seemed to be the cause of premature coolant hose wear, causing a small but pesky leak. It was a problem also on 2010-2012 (or later) Range Rovers with this same JLR V8.

 

For Evoque with Petrol ingenium engines - yes 2018 onwards.
Diesel Ingeniums were fitted on Evoque from around mid/late 2015 onwards I think.

 

correct, but since this is a US-based forum, I didn’t mention the diesel as it wasn’t sold here. The I4 Ingenium diesels are terrible engines.

 

Just to clarify my personal situation --- I owned a post 2018 Evoque with an Ingenium engine. I had two issues with it -- both requiring replacement of the Turbo. One was not a technology fault (instead a rodent chewed up the wiring to the turbo). All else about the engine was excellent.

Yes, you are correct my ZF transmissions on the LR4s are 6-speed ... with the large V8. No trouble at all with those items, except being constantly aware of the dynamic load on the timing belt tensioner and the fatigue wear of the plastic manifold components. Use of high quality oil, changed frequently, along with aged-driver, slow acceleration have helped me avoid having to change out the timing belt components prematurely.

Brake changes on the LR4 are very frequent and expensive -- as its an exceedingly heavy vehicle.

 

2 things I know for a fact.....

1- Change your oil at least twice a year no matter the mileage. AND, even better if you do it the right way, meaning draining from the oil pan to flush any metal shavings.

2- That's something I learned with my Jeep, to keep it happy, install a trickle charger and plug it overnight at least 3-4 times a week to keep battery and ecus happily fully charged.

Never a problem.

 

Yeah I had a 2011 LR4 that was bought new. In the 10 years and 95k miles we had it, I never had any timing chain issues. Did oil changes every 5k and they were in perfect shape. No slack in them when poking them with a screwdriver through the oil cap.


But yes, I think I went through three sets of coolant crossover pipes on mine. Now the OEM replacement parts for supercharged engines are metal instead of plastic. (Odd since very very early versions came with metal pipes from the factory). However I believe the NA versions are still plastic.
