The #1 complaint from Chery Tiggo 4 owners across Reddit, Facebook groups, and owner forums is overly sensitive ADAS safety features. Lane keep assist beeps constantly, forward collision warning triggers falsely, and ABS lights flash randomly. Here's what's wrong and how to fix it.
The Problem: Why Is ADAS So Annoying?
Chery's ADAS system was designed for Chinese roads and driving conditions. When sold in Australia, the system proved overly sensitive for local conditions - narrow lanes, aggressive lane changes, and different road markings trigger constant false alarms.
Symptoms Owners Report
- Lane Keep Assist beeps every time you get close to lane lines
- Forward Collision Warning triggers when there's no obstacle
- Automatic Emergency Braking activates unnecessarily
- ABS warning light flashes randomly
- System disables itself temporarily after too many false alarms
The Fix: May 2025 Software Update
Chery Australia acknowledged this issue and released a major software update in May 2025. The update includes new hardware sensors and local ADAS tuning specifically for Australian conditions. Over 80% of owners who got the update report significant improvement.
How to Get the Update
- Book a service appointment at your local Chery dealer
- Mention the 'May 2025 ADAS software update' specifically
- The update is FREE under warranty
- Takes 2-3 hours to complete
- If your dealer doesn't know about it, call Chery Australia directly
Manual Workaround: Disable ADAS Features
If you can't get to a dealer immediately, you can manually disable the most annoying features. Note: this reduces safety, so only do this temporarily.
- Go to Settings > Driver Assist on your infotainment screen
- Toggle off 'Lane Keep Assist' - stops the constant beeping
- Toggle off 'Forward Collision Warning' - stops false alarms
- Keep 'Automatic Emergency Braking' ON - this one actually works well
- Note: These reset every time you restart the car
Owner Success Stories
From Reddit r/CarsAustralia: 'Got the May 2025 update last week. The difference is night and day. Lane keep still works but doesn't panic at every white line. FCW actually waits until there's a real threat. Should have done this sooner.'
What If the Update Doesn't Work?
About 10% of owners report the update didn't fully resolve the issue. In these cases, the problem may be a faulty sensor or calibration issue. Your dealer can recalibrate the ADAS sensors - this is also covered under warranty. If issues persist after recalibration, Chery Australia will replace the ADAS module.
Prevention Tips
- Keep your windshield clean (dirty glass affects sensors)
- Don't mount dashcams or GPS devices near the ADAS camera
- Update your infotainment firmware regularly
- Report issues to your dealer ASAP - don't wait
- Join Chery Owners Facebook groups for real-time update notifications
The Bottom Line
The ADAS sensitivity issue was real, but Chery Australia has fixed it with the May 2025 update. If you haven't gotten the update yet, book a service appointment this week. For most owners, this single update transforms the Tiggo 4 from 'annoying' to 'actually quite good.'
