What is the solution for the Regal's 'Please shift to P gear' issue?
2 Answers
Here are the solutions for the Regal's 'Please shift to P gear' issue: 1. Gear shift mechanism: Use Buick's diagnostic computer to check for any fault codes. If the P gear contact switch inside the gear shift mechanism has poor contact, the gear shift mechanism needs to be replaced. 2. Gear shift panel: The gear shift panel of the new Regal should be disassembled to check for any faults. After removing the gear shift panel of the Regal, observe whether the clip of the gear shift lever dust cover has fallen off. If the clip of the dust cover has fallen off and is stuck on the gear shift lever, causing the P gear not to be fully engaged, the dashboard will display a warning. Removing the clip will resolve the issue.
I also encountered this warning with my Buick Regal. At first, I thought the car was about to break down, but later discovered it was because the gear shift lever wasn't fully pushed into position when parking, causing the sensor to misread. The solution is quite simple: first, make sure the vehicle is completely stopped and turned off, press the foot brake firmly, then push the gear shift lever forcefully into the P position until you hear a click. If the warning persists, try starting the engine and turning it off again, or operate on level ground. This issue is common in cold weather or when the battery is weak, as the sensor responds sluggishly. I've developed a habit of confirming the gear position before parking to avoid trouble. If all else fails, take it to a 4S shop to check the transmission switch or wiring connections—don't attempt to dismantle it yourself. Safe driving is paramount; never ignore such warnings, as failure to lock the gear could lead to dangerous vehicle slippage.
