Three problems related to brake light on have been reported for the 2017 Chevrolet Silverado. The most recently reported issues are listed below.
Stability track warning, abs and brake light warning all appeared on same day after moving from parking spot and turning out. Cruise control not working. Power steering is strained.
The abs system failed when braking on a snowy, icy, slippery road locking all four wheels causing the vehicle to skid out of control. The brake light and abs light and tcs icon were displayed. The brakes had to be released to regain steering control and judicious use of manual braking eventually brought the vehicle to a stop. The abs pump motor was noted running continuously even with the engine off. Onstar diagnostics indicated a traction control system error. This braking failure occurred in conditions that the abs is specifically designed to prevent loss of control!.
While coming to a stop in turn lane, brake assist light came on. Intermittent issue. After couple days of experiencing, I take truck in to find out about recall. They perform reprogramming. Doesn't fix issue. Tell me I have to pay diagnostic fee. Thy find vacuum pump needs replacing. They covered cost under "special coverage" because they know it's faulty (but not covered already under recall?). They say it's fixed. I pick the truck up, brake assist light comes on driving out the parking lot. Take it back next day. They tell me "pin" in the connector is broken causing "ground fault. " they charge me $500+ to run new wire in wire harness. Same connector that would have to be touched while replacing vacuum pump. I pay to have pin fixed. 3 weeks later, brake assist light comes back on with same exact symptoms. This time, they tell me ecbm need to be replaced. Not just reprogrammed. Somehow, the prior times, the error code wasn't stored. A) errors aren't being stored b) they're covering their warranty cost by charging for other adjacent parts c) brake assist issue going on for nearly 8 weeks now unresolved. They need to expand their recall to include adjacent "connectors" which the dealer admits hardly ever fail. Also should include vacuum pump not just as special coverage. Also, recall should expand to replace ecbm because apparently they aren't storing fault codes when they occur. I read this same thing across many forum posts online. All the same issues. Hard braking, or soft mechanical brake feel. I've now spent 1100 dollars on a problem that falls squarely within the description of the recall. They tell me that "these parts" aren't covered under the recall. I say, expand the recall. Recall states they don't have to include this in sec filings. I think they are under representing their true costs. My gm case #9-5696419690.
