NHTSA Complaint #11553194 — 2013 CHEVROLET MALIBU

In July 2023, my husband was driving ON THE HIGHWAY when the car suddenly decelerated itself. A system error message came up saying service stabilitrak and reduced engine power - he couldn't go more than 40 mph. We took it to the repair shop and they determined the high pressure fuel failed and the engine was running off the lift pump. They replaced the high pressure fuel pump with gasket and pressure line. Then, in late September 2023, the car turned off while my husband was driving (while he was stopped). He was able to turn it back on and drive it home. There were no warning lights/messages. We took it to the repair shop, but there were no error codes and they were unable to determine the issue. Next, at the end of October 2023, when coming to a stop the vehicle shut off again - almost every time my husband would come to a stop. When this happened, it still had power (because the radio was still on), but he had to shut vehicle off completely and restart it each time. There were no warning lights/messages. We took it back to the repair shop. Again, no codes were stored in ecm/tcm. This time, they test drove it while monitoring the data. They determined that the torque converter clutch was hanging up. They also experienced some long shifts and occasional slippage and determined that the transmission would need to be replaced. The issues above are just the most recent issues. Aside from regular brakes, tires, and oil changes, other work I’ve had done on the car includes the repair/replacement of: rear suspension toe link recall (three times), water pump, brake booster vacuum, a/c compressor, timing chain, guides, tensioner, cam actuators, intake and cam actuators, exhaust cam solenoid, exhaust manifold bolts with associated hardware and gaskets, thermostat (twice), battery (twice), spark plugs, and back left hub assembly. I have still have the documentation for all of the above.
