L405 Supercharged Ownership Concerns

I am considering trading my 2013 LR4 HD for a 2018-2019 CPO RR SC. I have a bunch of off-roaders and don't need my daily Land Rover to have a winch, steel bumpers and meaty tires like the LR4. Reviewers say these L405s are the best RR yet, even from a reliability standpoint, and it would fit what I am looking for.

However, I have found a few accounts of 2013-2015 RR/RRS SC engines suddenly quitting without warning. The accounts of failures I found include spun bearings, overheating without the gauge going off, and timing jumping. Mileage in these accounts has been as low as 42K miles and, to my knowledge, the 5.0 SC in these is the same as the 2018-2020 L405. These $30K+ repairs make timing chains, coolant outlets, and AC compressor concerns about LR4s seem paltry in comparison.

Is complete engine failure before 100K miles something I should be concerned about with these trucks, or is it super rare? I regularly work on my cars since I own a bunch of older Rovers. If a 5.0 SC just dies without warning though, that's a no-go. The idea of dropping $80+K on a truck just to have an engine randomly pop a year or so later makes me want to consider a Jeep or GMC.

I think that what your describing is rare. But I would consider a non supercharged L405 for several reasons. First off a lot of standard issue repairs will cost more on a supercharged car. Just more labor cause the things in your way. Then the brake jobs every 20,000 miles will be more expensive cause of all the Brembo going on. 6 piston Brembos will stop on a dime, But the pads and rotors are super expensive. Then the ACtive Cornering has been rotting the lines out and I’m pretty sure my guys are charging close to 40 hours for replacing both front and rear line sets.

Thank you, that is valuable insight. Since I am looking at the facelift 2018+ trucks, I'm stuck with either the 5.0 SC or 3.0SC, and I'll take the V8. From what I understand, the Td6 could bring its own share of horrors.

I have no problem with brakes or control arms, but forgot that the full size RR had ACE. I know the ACE swaybar would leak in the old RRS. Do you know if the rot from moisture build-up in the lines (poor servicing), or road salt in snowy areas? Depending on the diameter of the lines, I wonder if a compression fitting could be used to repair a section versus a whole line like LR would do. Either way, I wasn't thinking about ACE problems, so thanks for the heads-up.

Yes the TDV6 can be a huge problem. I know some people who tow big horse trailers and love the things. But they get carbon build up real bad. EGR valves get so shitted up they have to be replaced. I've seen them get so carboned up that the intake manifold has to be replaced. The def fluid system is a fucking nightmare.

The rot on the lines seems to be because they lay close to the left side splash shield. It’s close enough that debris can collect in them and hold moisture. I think if that stuff was cleaned out and maybe the lines repositioned a little further from the shield(upwards) they might do a little better.
I think the sway bars are improved cause I don’t see them leak much anymore. The bars a much easier to get in and out on a L405. Much more serviceable than the old Sports.
