What Causes a Malibu to Suddenly Stall While Driving?
2 Answers
There are several main reasons why a Malibu might suddenly stall while driving: 1. Use of substandard fuel: Automatic transmission vehicles generally don't stall easily. When they do, the primary cause is usually the use of substandard (non-compliant) fuel, which leads to engine carbon buildup and subsequent stalling. 2. Engine control unit (ECU) failure: Considering the mileage, prolonged use increases the likelihood of ECU failure. When the ECU malfunctions, it can cause the vehicle to stall - this is essentially a control system issue. Much like how the human body 'shuts down' when the brain malfunctions. 3. Insufficient driving skills: A driver's lack of proficiency or improper operation can also lead to vehicle stalling.
My Malibu suddenly stalled last time and it really scared me. This kind of situation mostly occurs in the fuel supply system, possibly due to a fuel pump failure. That thing is submerged in the fuel tank, and over time the coil is prone to burn out. A clogged fuel filter can also cut off fuel supply - when the car can't 'breathe', it naturally stalls. Did you notice any jerking before the stall? If so, it's probably an issue with the ignition coil or spark plugs. Loose battery terminals are another common cause, especially prone to poor contact on bumpy roads. By the way, check the alternator belt - if it breaks, the whole car loses power. I suggest not trying to fix it yourself blindly. You need to read the trouble codes immediately - only the dealership's computer can pinpoint the real culprit. Stalling in the middle of the road is too dangerous.
