U0184 on Jaguar by model: symptoms, diagnosis and fix
The 2016 facelift replaced the original X351 head unit with InControl Touch Pro (10.2-inch screen). Owners report the screen going black or freezing, the unit rebooting mid-journey, loss of navigation, phone and audio, and the on-screen climate/seat controls becoming unresponsive. JLR issued a string of software updates (Jaguar technical bulletin JTB00593 series for 'InControl Touch Pro features not functioning as expected') and a US class action was filed over Touch Pro/Touch Pro Duo behaviour in 2018-2020 models; owner threads document repeated dealer updates that only partially fixed the problem. The earlier 2010-2015 cars use a different (Bosch) head unit with its own freezing complaints, so the two should not be merged.
Common Symptoms
- Infotainment screen goes black or freezes
- System reboots by itself while driving
- Loss of navigation, Bluetooth phone and audio
- Touchscreen climate and seat controls unresponsive
How to Fix
No recall. Have the dealer load the latest InControl Touch Pro software (multiple releases were issued under the JTB00593 bulletin family); a hard reset (hold the power button 10+ seconds) clears a frozen unit temporarily. Persistent failures after the latest software require replacement of the infotainment master controller (IMC) module, which is expensive out of warranty. Check whether an extended warranty or goodwill applies before paying.
