Two problems related to engine shut off without warning have been reported for the 2015 Chevrolet Suburban. The most recently reported issues are listed below.
Purchased vehicle in March 2020, have had 4 instances of making a left hand turn and vehicle shuts off. Have read that steering assist recall was done, but from what I've read this is exactly what it is doing, low speed and making a turn. Any suggestions or have others experienced same? date is last time but has happened about 4x s now since last summer.
Vehicle loses braking capability at low speeds, sometimes voltage issues cause stability control error, and even complete loss of engine power and vehicle control (engine shutoff). This has been recurring approximately once per day for two weeks, generally at very low speeds and turning into a parking spot. Typically, abs engage and power brake assist is lost, which requires more more effort to stop the vehicle. Can also happen in reverse.
