TrueDelta Reviews the Reliability And Durability of the Lexus IS

Lexus IS Reliability And Durability: Pros
YearComment
2016 No matter how much Lexus improves the IS, the primary reason to buy one instead of something European or American (or even the Infiniti) will likely remain reliability. Audis and BMWs have become more reliable during the first few years of ownership, but once out of warranty they remain frightening propositions. Many remain reliable. But some owners live horror stories. The Infiniti Q50 has done well in TrueDelta's reliability survey but poorly in others. The key difference: we don't count software-based or usability issues that others do. The Q50's infotainment system has had issues. The G35 / G37 that preceded the Q50 has tended to be a better out-of-warranty bet than the Europeans, but some owners experienced excessive oil consumption and the odds of getting a lemon were higher than with the Lexus. full 2016 Lexus IS review
