At this point in time, most luxury SUVs had evolved into pampering on-road transport for their well-heeled buyers, backing away from off-road prowess and their truck-based roots. So does that make the Lexus GX a dinosaur? Nothing is "crossover" or "car-based" in this old-school vehicle. Consider the GX a Toyota 4Runner that was sent to finishing school, earning straight-A's when it was there.

Battery cables

"With an aftermarket battery from a reliable brand (Interstate) had a couple of failure-to-start occurrences. Troubleshot it down to a seemingly tight positive post battery connection - where the cable is completely tightened but not making consistent connection because the connector is slightly too large for the post. Negative post connector fastener wasn't bottomed out as was the fastener for the positive post connector. Solved the problem by "staking" the post - using a nail set to misshape the soft metal a bit so the connector would fully engage without the fastener bottoming out."
