Specs side by side
What owners say
XE
Overall
Mixed sentiment with a clear generational divide. The driving experience is consistently praised as a major strength, with owners highlighting nimble handling, balanced agility, responsive steering, and a truly dynamic feel in sport modes. The design and styling are also frequently cited as positives, offering a rarer, more distinctive alternative to mainstream German competitors.
Best version to buy
The post-2019 facelift model is strongly recommended over the first generation (2015-2018) due to corrected flaws and improved reliability, particularly regarding the timing chain issue on diesel engines. For engines, the 3.0-liter supercharged V6 petrol (XE S) and the 2.0-liter petrol units are viewed as much safer and more reliable choices than the early 2.0-liter Ingenium diesels.
Known issues
- Catastrophic timing chain failure on 2.0L Ingenium diesel engines (pre-2019): Engine destruction, loud rattling on startup, repair costs exceeding £15,000 ($19,000 USD). Frequency: very frequent.
- Buggy, slow infotainment system: Long boot times, intermittent crashes, frequent disconnections, screen freezing, requires unit replacement. Frequency: very frequent.
- General electrical faults: Failure of heated seats, heated mirrors, central locking motors, gear selector motors. Frequency: recurrent.
IS
Overall
Mixed sentiment heavily dependent on generation and powertrain. The IS is widely recognized for its strong long-term reliability, comfortable ride, and luxury feel, particularly when compared to German competitors. However, significant and recurring criticisms are directed at specific mechanical flaws, outdated powertrains, and poor fuel economy.
Best version to buy
IS 350 with the 2GR-FSE V6 engine is the most frequently recommended version for its superior power and reliability over the IS 250. For the third generation (3IS, 2014+), the 2015-2016 model years with the V6 and 6-speed automatic transmission are specifically highlighted to avoid the later UA80 transmission used in 2017+ models.
Known issues
- Carbon buildup on intake valves (IS 250 with 4GR-FSE engine): causes loss of power, rough idle, poor fuel economy, requires periodic cleaning. Frequency: very frequent.
- Water pump and front cover oil leaks (2GR-FSE V6 engine): common failure requiring expensive repair (engine removal for front cover, ~20-25 hours labor). Frequency: very frequent.
- Severe diesel engine issues (IS220d with 2AD-FHV engine): chronic DPF filter and EGR valve clogging leading to very high fuel consumption, potential for catastrophic engine failure (head gasket, seals) especially with poor maintenance.
The verdict
The Lexus IS is the better choice for most buyers.
It has stronger reliability sentiment in owner reports than the Jaguar XE, based on the data above. If the specific known issues on the Lexus IS are a dealbreaker, the Jaguar XE is worth a closer look instead.
