Land Rover Defender 110 vs Toyota 4Runner: Reliability Compared
Land Rover Defender 110
Toyota 4Runner
In this matchup, the Toyota 4RUNNER comes out well ahead of the Land Rover Defender 110 on reliability. The deciding fact is the Defender's DC/DC converter, which can cut power and steering, and which owners say failed again after replacement. The 4Runner draws far fewer complaints per vehicle sold.
How Do the Land Rover Defender 110 and Toyota 4Runner Generations Compare?
Verdict
The Toyota 4Runner is more reliable than the Land Rover Defender 110, scoring 80/100 vs 60/100.
Reliability clearly favors the Toyota, and the gap is large. Owners file far fewer complaints per vehicle sold: 1.5 per 10,000 against 20.7 for the Defender. The deciding issue is how the Defender fails. A faulty DC/DC converter can cut power, steering and brakes, and owners say replacement converters failed again. The 4Runner has real faults too, including stalling and airbag non-deployment reports, but its complaints are spread across several systems instead of piling up around one repeat failure.

What Are the Common Problems With the Land Rover Defender 110 and Toyota 4Runner?
The Defender's trouble centers on electrical power. The DC/DC converter stops charging the 12-volt battery, an "Electrical fault detected" message appears, and the vehicle can lose steering, stall in traffic or refuse to shift into Neutral. Cracked windshields and burned-out LED daytime running lights add costly, non-mechanical complaints. The 4Runner's most common report is a steering wheel shake at 50 to 70 mph that tire work does not cure, plus brake squeal and rodent-chewed wiring. Airbags are its most serious crash-linked area: 20 of 24 complaints involve crashes, mostly front airbags that did not deploy. The Defender has no comparable crash-linked cluster.
