Tribeca Airbag Warning: Rollover Sensor Mystery Solved

I experienced a similar vehicle safety issue with my 2013 Subaru Outback. Having some mechanical experience, I initially thought I could diagnose it myself, but the SRS sensor system is too complex for DIY repairs. The crash detection warning light appeared suddenly, and the diagnostic scan revealed rollover sensor communication errors. The safety system was showing identical symptoms to what you describe. After checking online resources, I took it to a certified workshop. They confirmed the control unit was defective and needed replacement. The total repair cost was 1000€, including diagnostics, parts, and labor. The fix completely resolved the issue, and the warning light has not returned in the 18 months since. To provide more specific advice about your situation, could you share: Have you had any recent work done on the vehicle? Did the warning light appear suddenly or intermittently? Are there any other warning lights active? Have you had the specific error codes read? The SRS system is critical for vehicle safety, so I would recommend getting it checked soon by a certified technician who can properly diagnose and repair these sensitive components.

Thanks for sharing those details. Last service was at 95000 KM, and looking at my records, I have not had any previous SRS-related repairs. The warning light appeared intermittently at first, then became constant about 2 weeks ago. No other warning lights are active. I did get the codes read at a parts store, it showed error B0101 which points to the rollover sensor communication fault. Your feedback about the automotive sensor replacement is helpful. If the repair cost is around 1000€, it helps me budget accordingly. Given how critical the safety system is, I will schedule an appointment with a certified shop this week rather than attempt any DIY fixes on the sensor failure.

Having gone through this exact issue, I can confirm that the B0101 code you mentioned is consistent with what my Outback displayed when the automotive sensor failed. The progression from intermittent to constant warning is also identical to my experience. The tilt sensor malfunction typically requires complete replacement of the unit, as repairs to individual components are not recommended for safety systems. When I had mine fixed, the shop explained that attempting partial repairs could compromise the vehicle rollover detection system. Since your mileage and symptoms match my situation closely, I am fairly confident you are dealing with the same sensor failure I experienced. The repair price I mentioned (1000€) should be in line with what you might expect, though parts costs can vary. One additional note from my repair experience: make sure the shop performs a complete safety system diagnostic after installation. My technician explained that proper calibration of the new rollover sensor is crucial for the system to function correctly. Let us know what the certified shop finds when you take it in. Their diagnosis will help confirm if your issue mirrors mine exactly.

Thanks to everyone who provided input. Just wanted to update that I took the car to a certified shop today. Their diagnostic confirmed exactly what was discussed, a faulty rollover sensor in the SRS system. The crash detection module had indeed failed, matching the B0101 code previously identified. The repair estimate came in at 950€, right in line with the cost mentioned earlier. They will be replacing the complete automotive sensor unit rather than attempting any partial fixes, which makes sense given the critical vehicle safety functions involved. I scheduled the repair for next week. The technician explained they will perform a full system calibration and testing after installing the new SRS sensor to ensure proper vehicle rollover detection. Really appreciate the advice about not attempting DIY repairs on these safety systems. Having a professional handle this gives me peace of mind that the fix will be done correctly. Once the repair is complete, I will post another update about the final result. Hopefully this thread helps others who encounter similar sensor system issues in the future.
