There are 5 owner-reported electrical system complaints for the 2014 Chevrolet Suburbanin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Stopped at a stop sign. The vehicle suddenly lost all electrical power. Lights began flashing. Traction control system turned off and on. Then it went back to normal driving. I just had the Chassis Control Module Recall taken care of as well. The air conditioning is intermittently cutting its ability to cool then suddenly cooling again during this time. When the vehicle turned back on, the strong odor of fuel was present from the air vents. I had reported the issue before but was told by a dealer there is nothing wrong they could see beyond a visual inspection.
The contact owns a 2014 Chevrolet Suburban. The contacts stated while driving at night at an unknown speed, the high-beam headlights were activated to see the roadway. Several unknown warning lights then became illuminated. The vehicle shuddered and jerked for approximately 30-40 seconds before resuming normal driving. The contact stated that the failure occurred after activating the high-beam headlights. The vehicle was taken to the dealer to be diagnosed; however, the mechanic was unable to duplicate the failure. The vehicle was not repaired. The contact felt unsafe driving the vehicle. The manufacturer was not notified of the failure. The failure mileage was approximately 143,000
WHEN TURNING ON THE VEHICLE THE LIGHTS WILL POWER SURGE. ONE DAY THE VEHICLE JUST DIDN'T START. THE NEXT DAY IT STARTED AND AS I WAS DRIVING DOWN THE ROAD I LOST THERMOSTAT CONTROL, THE POWER LOCKS WERE INVOLUNTARILY GOING UP AND DOWN, THE RADIO SHUT OFF, AND THE SPEEDOMETER AND GAUGES ALL WENT TO THE LEFT AND WERE NOT WORKING. WHEN I FINALLY PARKED THE VEHICLE I COULD SMELL AN ELECTRICAL BURNING SMELL. THE VEHICLE WAS IN MOTION FOR ALL OF THIS ON A 2 LANE ROAD.
AFTER PARKING THE VEHICLE AND TURNING OFF THE ENGINE WHEN THE KEY IS PULLED OUT OF THE IGNITION THE POWER DOORS WONT RELEASE AND POWER WINDOWS WONT WORK. WHEN STARTING THE VEHICLE AND TURNING BACK OFF THIS FIXES THE PROBLEM. THIS OCCURS ANYWHERE AND SPECIFIC TO PARKING THE VEHICLE. THE REMOTE START WORKS INTERMITTENTLY. SOMETIMES IT WILL WORK AND KEEP THE VEHICLE RUNNING AND OTHER TIMES IT WONT WORK AT ALL. THIS OCCURS ANYWHERE AND SPECIFIC TO THE VEHICLE PARKED. FOR NO REASON, THE CLOCK WILL RESET THE TIME AND DATE SO IT SHOWS 12:00 FOR THE TIME AND 01 01 2005 FOR THE DATE. THIS HAPPENS NO MATTER IF THE CAR HAS BEEN RUNNING THEN SHUT OFF AND THEN DRIVEN AGAIN OR IF THE CAR HASN'T BEEN DRIVEN IN A COUPLE OF DAYS. THESE PROBLEMS HAVE ALL OCCURRED ON DIFFERENT DAYS BUT HAVE BEEN SPORADIC AND NOT OCCURRED AT THE SAME TIME. ALL THESE PROBLEMS HAVE BEEN OCCURRING SINCE APRIL OF 2019.
