Only becaused you asked
I will start by saying all three were purchased from the dealer certified pre owned. So that being said they were up to date on maint when I got them and I only took them to the dealer. they all had extended warraties so the dealer fixed everything for free or 100 dollars so they looked for things to send to the warranty shop.
All three in CO, not wheeled hard, minor stuff.
The 99 had the head gasket replaced twice in the 15k to 20k miles I had her. The sun roof channel leaked and needed to be cleaned replaced with the oil changes. The MAF went out 2 or 3 times I can not remember. The ABS sensors went out every two to 3 months. The Rear leveling suspension went out twice. Numerous electrical gremlins I can not remember. once it reached a non warranty state I traded it in.
I got a 2003 discovery which was in the shop so much they took it back after 4000 miles as a lemon basically. They gave me my money back in full to include all fees and taxes. It was in the shop for a leaking windshield, sun roofs, door seals, head gasket, ABS sensor, wiper switch, and a host of other issues. I may still have the folder together on it.
So I used the money returned on a low mileage 2004 Discovery. It suffered from seperation anxiety as well from the local Land Rover Dealership. It was always something little, but electrical which sent me to the shop to have it checked out and replaced. It also had the head gasket replaced. I finally gave up on the brand and bought a Subaru as a daily driver.
I changed for a couple of reasons. I bought my wife a new sequioa and the Toyota has only seen the shop to change the oil. In 6 months nothing. The Discovery averaged 1 trip a month. We did not need 2 large 4x4 vehicles. I have 2 daughters and I want to spend time with them not going to the shop early to get a loaner car or to be dropped of at work. There was a running joke here at work with my discoveries. They were always in the shop. I wouldhear not again a ride to the dealership.
The price of gas, we didn't need two v-8 trucks. The Toyota gets a couple of miles better than the Disco and my wife does not drive as far every day.
I am not bashing LRs as I own 2.25 of them. 1 1960 88 I plan to drive to Moab for a 4 day excpedition run in 2 weeks. A 1959 109 Dormobile I am putting back together, and the remains of the 1967 dormobile I am swapping parts from.
The LR was a great truck, but I would not trust mine to get me to SA. I would drive from CO to TN, but I expected to have a light or two on most of the trip. It would make it, but would I really trust it all the way to SA? Not me personally.
If I only had one, call it a lemon, if I had two call it a trend, I had three and I call it a problem with quality.
My 2 cents to be read or ignored.
