2015 Chevrolet Malibu: start-stop system problems

Filed May 24, 2024 · Acceleration, Brakes · SC

Wheel hubs causes car to think that it’s going faster(200mph) causing car to drop speed, locks steering wheel making it impossible to turn away from traffic and drive it’s an accident waiting to happen not sure why there isn’t a recall. Also batteries causes the battery system warning to be a major problem even if alternator is good. I’m not sure if the two batteries is a good idea. The stop/start feature can cause radio issues it’s like cutting the car off and turn it back on when brake is released radio comes back on.

During the automatic start/stop function, the car stalls out after it stops itself. For example, I exited an interstate and came to a red stoplight. The car engaged the fuel saving system and shut down the engine. However, after I tried to press the gas to get the car to reengage, the car completely shut down requiring me to put the car in park on an exit ramp and re crank the car to get it to start again. Batteries were tested and no one can figure out what the problem is.

Initially, circa two years ago, had an electrical failure on hard braking - the radio display screen and other electrical shut down, car stalled. After restart, car would only move forward slowly. Eventually this cleared. The car has had a total of ~5 incidents of complete battery drain and consequent failure to start after sitting, even though the alternator previously was spinning, and "battery voltage" reports as somewhere in the 13-14 v range. On three separate repairs, dealer has replaced the aft battery, then the forward battery, then updated flash memory (of battery control? Antilock brake control, not sure), per a recall notice affecting other nearby model years. After this, the car went several months without incident, but drained battery and failed to start again this week. It appears that the complex auto stop/start electrical system is flawed in such a way that the local dealer cannot diagnose why the battery keeps draining. Because the forward battery capacity is very large, and usage of the car is low, it takes several months to drain the battery. When the battery is drained, the car no longer functions - power steering, electronics, etc, hence it is a safety issue if it happens while driving.

Tamara recall this vehicle has the auto stop start system where the engine is supposed to engage at a light, and it does not work. No one can understand why it won't engage and the dealer will not help me. The vehicle works and drives fine but this system is flawed and all over the chevy forums people are experiencing this same problem.

While driving the vehicle I stopped at a stop light and the car turned off due to the auto start/stop when idling. When I let off the brake, the car did not turn back on. After attempting to start the car again numerous times it would not. All electrical stayed on at this point. Car was towed to a chevy dealer in fenton, mi and they replaced battery and battery current sensor. Later I turned the car off and the radio and screen stayed on even after closing and opening the door. Then my car was idling at a stop light today and it auto turned off as when I let off brake it did not turn back on. All electrical stayed on. This time I was able to start the car back up but there's no telling when this will happen again. Very dissatisfied with this vehicle.
