2017 Chevrolet Malibu Powertrain (other) Problems

When the vehicle is shifted into Park and the ignition button is pressed, the vehicle fails to shut down. The dashboard displays a "Shift to Park" warning message, indicating the vehicle does not recognize that the gear selector is physically in the Park position.To shut the engine off, the driver must repeatedly wiggle, slam, or cycle the gear shifter back and forth into Park until the electrical sensor finally registers the connection. This creates a severe safety hazard, as the vehicle can roll away if left unsecured, drains the car battery, and prevents the doors from locking properly.Crucially, this defect traps drivers inside an operational vehicle for extended periods while they repeatedly struggle to force it to shut down. This poses an immediate risk of heat-related illness or death (hyperthermia), especially in high-temperature environments, during heatwaves, or for vulnerable occupants like children and the elderly who cannot exit the vehicle safely until it is off.

Shift to park error on dash. GM is aware of this issue and won't do anything about it. This causes stress and can cause battery drain. The issue lies within the microswitch that reads that the shifter is in park. The metal arm that activates the switch wears down or the wiring is faulty. Several Malibus, as well as other models have this issue and Chevy dealerships want hundreds to thousands of dollars to fix this. If it's a known, repetitive issue on several models, it should be a recall. This causes owners to try to fix this issue themselves, which can cause more damage and more money.

The SHIFT TO PARK warning light comes on when shifting to park and WILL NOT allow you to shut the vehicle off. This is a WIDELY KNOWN DEFECT in multiple GM vehicles and yet there’s still no recall! WHY?! It causes the vehicle to not completely shut down, killing the battery and could potentially cause the car to roll. It’s been WIDELY REPORTED and it’s absolutely a defect with a part inside the shifter! It’s an expensive repair that consumers SHOULD NOT have to pay when it’s a DEFECT on GM!!! PLEASE RECALL!!!!!! After researching this issue, there’s MULTITUDES OF COMPLAINTS and even a class action lawsuit (of which I wasn’t aware of) but it shouldn’t have to turn into a lawsuit when the NHSTA has the ability to force GM to MAKE THIS RIGHT by REPAIRING IT!

Every time I shift the car into park, I receive a "shift to park" warning on the informational display. I am unable to turn car off until the car recognizes it. Can sometimes take 10 minutes before I can get car to recognize. This was fixed once before while under warranty and fix lasted 3 years. They cleaned the park switch contacts and installed an online shifter jumper harness but will not cover the fix now that it is happening out of warranty. It's a known issue that mechanics say is so common a recall should be issued.

I have had 2 incidents, and paid for repairs both times. When put in park, SHIFT TO PARK warning lights come on. First time, Oct 4, 2021. Second time Dec 16, 2024. In 2021 I was told there should be a recall, it happens a lot. I'm not seeing recall, and think I should get my money back.

Incident

Oct 4, 2021

While driving, random and complete engine power loss for several seconds, unable to accelerate at all. After power is regained, a cloud of white smoke is seen from the exhaust. The vehicle then drives completely normal, and no codes show up on the dashboard. This has happened three times within two months at around 100000mi on the odometer. Complete power loss could result in being a hazard to other drivers, along with not allowing the driver to make decisions to avoid an accident or propel their vehicle forward. The vehicle is going in for inspection within the next two weeks to determine cause.
