The emissions modification calibration by Volkswagen causes the coolant to be exposed to elevated temperatures due to higher exhaust gas recirculation (EGR) use to control emissions. These elevated higher temperatures degrade the coolant faster than designed and lead to precipitates falling out of solution in the factory filled G13 coolant. This causes buildup and deposits to form throughout the cooling system, particularly in the heater core which can block proper coolant flow & lead to coolant system failure, specifically of hoses associated with the heater core. When these fail the engine can over heat, and stop which causes loss of steering, propulsion and braking abilities. There is a similar problem on 2012 models with the TDI engine, which has been addressed but the 2015 models are being stranded on the roads creating a safety hazard to the drivers of the vehicles and other motorists on the road.

After turning on the vehicle, I turned the steering wheel and heard a click, then the airbag malfunction warning light came on immediately. Horn and all steering wheel buttons have stopped working (radio control, cruise control etc). and airbag warning light remains on. This seems obviously to be the broken clock spring problem. Vehicle has about 105,000 miles on it. I am not sure if the steering area was ever serviced during a previous safety recall, but I have never had any service on the steering wheel or issues in that area.

Steering column control module with clock spring failed, / miles on car 54302. All buttons on steering wheel stopped working. No horn, air bag light on as malfunction, reports state hazardous to drive... took it in for replacement--cost $668.52. Other VW have had this problem as a recall.. please add to list of VW having this problem and insist VW pay or recall to have them fix this dangerous problem. I pulled into parking spot when it all stopped. Good this I was back home and not still up in the Sierra

Clock spring failed at 52,000 miles--affecting both the airbag and horn. VW refused to reimburse me for the repair, despite their clock spring recall on multiple VW models, that was initiated by NHTSA investigation.
