Things To Look for - Land Rover Range Rover Sport

Original 2006 Range Rover Sport  (C) JE Robison Service
2011 Range Rover Sport HSE (C) JE Robison Service

All in all, the 2006-2013 Sport is probably the most reliable Land Rover product to date.  That said, it is not problem free.  Poor maintenance is always a concern, and a high percentage of these vehicles were leased when new.  In my experience, leased vehicles are less likely to receive proper care than privately owned vehicles.  They tend to get somewhat less than the manufacturer service schedule calls for.  Trucks that are above 50,000 miles with marginal care are much more at risk for major failures or premature demise.

Sports come in two versions - standard (with HSE trim option) and supercharged (higher level trim standard.)  Reliability of the two versions is about the same but maintenance costs for the Supercharged trucks are higher.  Brakes are double the cost of standard.  Tires (20 inch in most cases) are quite a bit more.  And the Supercharged trucks can burn through brakes, tires, and full faster.

That said, if you drive a standard and a supercharged truck identically, they will return about the same fuel economy.  2006-2009 trucks have the original Jaguar/Land Rover DOHC V8; 2010 and newer trucks have the upgraded engine with significantly more power.  The exterior,  dashboards, and interiors were facelifted for 2010 also.

The 2006-2009 trucks are virtually identical, as are the 2010-2012 models.

Most late model Sports will be dealer serviced, and you should always look for a car with service records.  There’s no easy way to check service status otherwise.  Gaining access to a spark plug to evaluate freshness used to be a 2 minute job on the first Range Rover.  Now it’s an hour-plus task. The transmission fluid can’t be checked with a dipstick on these trucks.  To service it, you replace the integral pan/filter and fill with fresh fluid from below. 

If you buy a truck with 50k on the clock, and there is no record of recent undercar fluid services I would advise doing them all right away just to be safe.  Newer Range Rovers require special synthetic oil, and we urge you to follow their recommendation with respect to oil and grade.  The late model trucks have gone to an extended oil change interval and we’re not so comfortable with that.  We recommend a more conservative 7,500 miles as an oil change interval and synthetic oil in all years of Sport.  For older Sports we use Mobil 1 0-40.

We also recommend changing the front and rear differential lubes, and the transfer case lube.  Land Rover fluid is used in all three.  We suggest a change interval of 4 years or 60k miles.

If the vehicle has been driven in the city don’t be surprised if brake pads and rotors are worn out at 25,000 miles.  That is common.  Tires are often worn out at about that mileage too, though some of the replacements (Michelin for example) have proven longer-lived.

All of these trucks have air suspension, which is generally reliable.  Compressors tend to wear out near 100k miles and they make a $1,200 repair more or less (2015 $)  Struts can develop leaks and that will wear the compressors out faster.  Sensors are valves are generally rugged.

Pay attention to any warning lights or messages.

Other things to look at:
  •  We suggest a scan of all computer systems with a factory-level test system.   These vehicles have many computers (like climate control and security) that do not talk to generic OBD scanners, and they may alert you to significant issues.
  •  Have your nearest dealer check the VIN for open recalls and warranty status.  Checking for open recalls is a no-brainer but warranty status is not so obvious.  If a car is flooded it may not have a salvage title, but Land Rover will have been notified if insurance was involved and they will void the warranty.  A voided warranty status and a good title would be a “run-don’t-walk” flag for me in an inspection.
  •  Tire pressure monitor sensors have a service life of about 8 years, so you should expect to be replacing them soon or now on older trucks.
  •  Alternator failure is common, especially when batteries are allowed to age and overstress the system
  •  Check the cooling system for leaks, level, and correct fluid (orange in color.)  Water pumps and expansion tanks are two common leak areas.  Non-original fluid is a red flag.
  •  Front and rear wheel bearings are weaker than you’d hope on these trucks.  Failure before 100,000 miles is fairly common.
  •  The electric parking brake has been problematic on older vehicles.  The mechanism can corrode and jam, making for a $1,000+ repair and possibly tearing up the parking brake and rotors too.
  •  If the vehicle is in an area where they salt the roads chassis corrosion can be a problem.  Brake and fuel pipes tend to rust out before the frame.
  •  Lower control arms usually wear out between 60-90k miles.  The first thing to go is the bushings, but the joints often fail 30,000 miles later.  Some shops do bushings only as a cost savings but the whole arm will be needed when the ball joint wears out.  Most of the time we recommend changing whole arms for that reason.
  • Sway bars are a problem on these vehicles.  The bars wear where they pass through the chassis bushings, and they develop a heavy thumping vibration.  Replacement is a fair bit of labor as the body must be lifted partway off the frame.
The Range Rover Sport quickly became Land Rover's most successful model.  The Full Size Range Rover (the L322) is bigger and plusher, but also significantly more expensive. And the Sport has the advantage of being a newer design, and somewhat more nimble.

We are now seeing Sports coming through our service department with 200,000+ miles on the odometer and no major failures.  It takes good maintenance to get to that point but the Rovers we've cared for right along to that mileage seem to have plenty of life left in them.

The Terrain Response system made its debut in these models and it provides impressive off-road and bad-road traction.  We have not seen any significant service issues with terrain response; indeed most of the gadgets on these trucks have proven trouble free.

The only disappointment is that there is not a thriving off-road community building around these trucks, as developed around the original Range Rover, Discovery, and Defender.  These are fully worthy vehicles.

Pre Purchase Inspection of Cars

A beautiful dropped Bentley like this would be a fine addition to any collection

Experts agree - If you’re looking for a pre-owned high end car – of any vintage – you are well-advised to get a pre-purchase inspection.  In the real estate trade many banks won’t grant a mortgage to a home that has not been inspected and given a clean bill of health.  It’s a mystery to me why auto lenders don’t impose the same sort of rule with high-value cars.

Most home inspectors are certified or licensed and they have a set of standards they adhere to in the course of their work. Unfortunately, auto inspectors do not have licensing or standards that apply to this situation.  Most states license collision damage appraisers but that’s a totally different job.  Some states license mechanics as well but that does not say anything about their knowledge of a specific brand.  And fixing the mechanical problems isn’t the same as evaluating the whole vehicle. Dealerships may be of help, but their capabilities are often limited to current-generation cars and they tend to have a focus on quick maintenance and warranty repair, which has little to do with collector car evaluation.

The other issue with dealerships – and this is not too well known – is that looking cars over for problems kind of goes against what the manufacturer tells them.  One of the things carmakers watch closely is the stream of warranty repairs from their dealers.  Most manufacturers discourage dealers from looking for problems; they are supposed to respond to customer complaints but they are not supposed to go looking for little things to fix in warranty, unless they are safety hazards.

That makes sense from the manufacturer perspective, as they want to keep costs down.  But that and the fact that dealer technicians are mostly paid on a piecework basis means the techs have every incentive to whip through a job as fast as possible, and small issues that are unmentioned by the driver go ignored.  That’s not what you want when checking a complex old car.

Ideally you want an inspector who is a recognized expert on cars like the one you want to buy.  Inspecting a 1995 Rolls-Royce is very different from inspecting a 1995 Chevy Silverado.  A good used car appraiser can judge the originality and condition of paint on any car, but someone who is accustomed to “ordinary” cars may dramatically underestimate the costs to repair cosmetic flaws in Rolls-Royce or other high end vehicles.

Mechanical inspection is much more specialized and brand specific.  A successful inspection is predicated on knowledge of what goes wrong with particular makes and models.  This is particularly important when a manufacturer model line undergoes significant technological change.  For example, a technician who was trained on the 2003 and newer VW-based Bentley would have little to guide him when inspecting the servo brakes on a 1965 Bentley, which uses totally different systems.

My suggestion is that you look for an inspector on the forums of the marque club for the car that interests you.  For example, a prospective Rolls-Royce buyer would do well to join the club – www.rroc.organd ask about inspectors in the area on the club forums.  An endorsement from several club members would mean more to me than an ad from the Internet.

If the car club can’t point you to an expert, your best bet will be to find a qualified and impartial service facility and engage them to evaluate the car.  Thanks to the Internet it’s easy to look at reviews and descriptions of shops all over the country, and those shops may also be checked out on car club forums.  You could, for example, search out “independent Porsche service in Des Moines, IA” or “independent Land Rover repair in Springfield, MA.”  Call the shop, talk to them, and see what they say.

Once you find a person to inspect the car, it’s important to cover what will be inspected.  Here are some thoughts.  At a minimum, he(she) should . . .
  • Evaluate paint and body condition, including paint thickness; and the originality and completeness of trim
  •  Evaluate the interior condition, particularly with respect to the need for and cost of leather and wood repairs.
  • Evaluate the structural integrity of the car, including the frame and body.  This requires familiarity with the use of wood in coach-built bodies, and the structural weak points of the car under consideration.
  • Evaluate the mechanical condition of the car with respect to things that don’t work, are worn, or possibly unsafe.  This requires familiarity with all the equipment on the subject car and how it should work.  Knowledge of what fails and why is brand and model specific and valuable.
  • If you're looking at a pre-1990s car, you should expect a compression test and possibly a leak down test.  Compression is seldom checked on newer cars because compression is monitored by the engine ECU and a compression loss in a post-1997 car will result in a check engine code.
  • Expect a physical check of suspension, brakes, hoses, and undercarriage.  This will typically require a lift, and it’s one reason we only do these inspections in our shop (as opposed to wherever the car happens to be.)
  • Check the age of the battery, its condition, and the condition of charging and starting systems.  On a collector car look for a battery tender and possibly a cutoff switch.
  • Review the service records for the car and look for exceptionalities.  Also look to see if the car was cared for properly and what services may be due now.  Compare the written record to the observable evidence of the vehicle.
  • If you are looking at something exotic and fairly new a well-connected inspector may be able to access manufacturer service records.  They may also access the as-built record and compare that to the car’s appearance now.
  • The inspector should drive the car and evaluate its function on the road.  Does it feel right?  Is it free of rattles and annoyances?  Does it perform as it should, without overheating or showing other signs of trouble?
  • Look for the manuals, tools, and other little bits that came with the car when new. The more of that you have, the better in the collector world.  The inspection report should tell you what's there and what's not, and if there are any additional materials (car cover, sales literature, etc) that should be mentioned.  On a car like the Corniche S Rolls in the photos below you would spend several thousand dollars to replace missing manuals, tools, and key fobs. So be sure the inspector pays attention to that.
  • If the car being evaluated is newer than mid-90s, you should expect a scan of electronics and a report on issues that the scan reveals.  This would include fault codes, odometer discrepancies, changed modules and anything else unusual.  Note that a manufacturer specific scan tool is needed for this level of inquiry; the inexpensive generic OBD scanners won’t give this detail.
  • Compare the car to others of its kind – is the vehicle under study better than 90%, or just average? Why?  This requires extensive knowledge of the car line and model under study.


Don't forget the little things - owners manuals and tool kits for example

Here at Robison Service we produce a written inspection report backed up with photos, and I would expect the same in any intensive inspection.  But keep in mind that time is money – a really thorough inspection backed up with a well-documented report may cost you 6-8 hours of labor. Checking everything I list above is not a quick casual thing. That said, you don't always need that extensive a check. In some cases you may be well enough served by paying for 1-2 hours of the inspectors time and a verbal report.

When we inspect complex cars like Rolls Royce I tell potential buyers that I might reject an obviously unsuitable or problem-filled car in an hour's time but a thorough evaluation of where to go next on a promising car might take be 4-5 hours more as we check hydraulics and do other time consuming tests.  

I encourage is to have the seller present when the car is inspected, and I recommend you ask the inspector to present his findings to the seller.  That way you have less chance of a seller disagreeing with what’s being reported – he can disagree right then and there and a good inspector will support his position or recognize his error.

I hope this gives you a sense of what’s involved in a comprehensive pre-purchase inspection, and how to get one done.  The biggest problem – once you get outside the big cities – is finding qualified technicians to do the work.  If you are making a major investment, don’t hesitate to pay the costs to transport the car you are considering to someone really qualified to look it over.  And if the seller refuses when you offer to pay costs there (and back if needed) . . . consider that a big red flag. 

This process is often complicated when the car is in an auction environment.  At a Kruse or R-M style live auction you can usually arrange to inspect the car at the auction facility in the days before the sale, but the inspector will have to go to the vehicle and that may limit what they can check in the absence of a workshop and lifts.  When the car is on eBay there is no telling what the inspection environment may be.  Some cars will be at dealerships while others are at homes.  Sellers may or may not be responsive to your request to bring a car to a shop for inspection in an auction environment.

Depending on the complexity of the inspection and the detail of the report, an inspection like I describe may cost anywhere from $150 to $1,000+. If the inspector has to travel to the car or the car must be brought to the inspector those costs will accrue too.  Expensive as that may sound, it's a lot smarter to spend the money in due diligence than it is to pay top dollar for a piece of eye candy that falls apart as soon as it lands in your driveway.


It’s a buyer beware world out there, folks. Know what you’re getting.

A Fix For Land Rover Discovery II Frame Rot / Rust



Last year I wrote a story about the frame rust that is beginning to cripple Discovery II trucks that run in snow country, particularly the 2003-4 models.  At the time, the only fix was a new frame ($10,000+) or hand fabrication and patching (costly and not always successful.)  Today I am pleased to show a new and more affordable alternative.

Rovers North has begin selling rear frame sections that replace the last two feet of a Discovery II frame.  These premade sections have all the complex fitments that make one-off fabrication difficult, and they are easy to install (at least compared to the alternatives!)

Here is what a rotted frame looks like, pre-repair:


You don't see much damage from a distance but when you look close the rear frame rails are totally destroyed.  This happens because the rails are thinner than older Land Rovers, they are not protected inside, and they are designed in such a way that gravel can get inside. When that happens, salt water from winter roads soaks the gravel and the mix just eats the frame from inside out, but luckily only in the gravel spray areas behind the wheels.


In some cases the shocks towers corrode, weaken and break.  We see other issues like that but the main failure is what you see above - rot in the rear two feet.  Here's how we repair it now:


We remove the gas tank for safety and access. To do that the trailer hitch has to come off.  We usually send the bits of hitch for sand blasting and finishing – preferably powder coat for its durability.

The truck is set up on a body lift and the rear of the frame lopped off. Here is what the rotted segments look like on the floor:




The edges are smoothed and any corrosion extending forward is repaired.  Then the new frame rail ends are installed.  You can see how they slide over the original rails, and the six holes on each side give space for bolting and welding. 






The gold finish on the frame is a weldable corrosion resistant primer, so the repaired frame won’t be so quick to go the way of the original.

The rear crossmember will take some fabrication as you see, but it’s not a big deal.



These frames also rust and break alongside the right catalyst, and we repair that with plate to strengthen the sides and bottom of the frame for about two feet in that area.  Once the frame is repaired we still recommend treatment with Waxoyl.  The Waxoyl may not hold on badly rusted and flaking areas but it will significantly slow the progress of corrosion most everywhere else.  It's not optimal - applying on rusty frame - but it's the best post-repair preservative I know.  The image below shows a repaired area treated in Waxoyl:


We are very pleased to see these new frame rail repair pieces.  I predict they will save quite a few truck from the scrap yard!
