Should You Buy the 2020 Lexus GX?

Buy it with confidence on the record alone. Reliability is excellent, and this year sits well above average among 2020 SUVs. Within the GX's nine scored model years, it is among the stronger ones. Owners filed only 4 complaints, or 1.4 per 10,000 sold. The 2019 drew more complaints and rates worse, while the 2021 rates about the same.

The one pattern in the data is climate control. Owners report HVAC system failures, and these tend to start around 80,000 miles. One of the four complaints involved a crash. Federal recall records list no recalls for this year, so there is nothing on that side to chase down.

Ask for service records that show any HVAC work, especially on a GX near or past 80,000 miles. The 2021 is a close alternative, though it has had less time to collect complaints, so its single complaint says little.

Compared to the 2021 Lexus GX, which scored 1 points lower. See also the 2019 Lexus GX for an earlier comparison.
