Why does the Buick LaCrosse not move when stepping on the accelerator?
2 Answers
Main reason is excessive dirt in the transmission valve body: It compromises the quality and frictional characteristics of the transmission fluid. This increases friction and wear, while sludge also forms inside the transmission, causing blockages in the valve body and pipelines, thereby preventing proper regulation of oil pressure and leading to transmission malfunctions. Below is relevant information about the Buick LaCrosse: 1. Introduction: The LaCrosse is a new mid-to-high-end sedan launched by SAIC-GM on February 22, 2006. "La" represents a high-grade, upscale image, while "Crosse" carries the meaning of "breakthrough and transcendence." 2. Vehicle Design: The Buick LaCrosse adopts Buick's latest family design language, featuring smooth and elegant body lines and a highly dynamic body proportion. The wing-shaped full-LED automatic sensing headlights use advanced light curtain technology to create a more uniform and brilliant lighting effect.
A few days ago, I encountered a similar issue. My friend was driving an older model LaCrosse, and the throttle was completely unresponsive. I suggested he check a few things first: Is the transmission fluid too low or deteriorated? Transmission slippage often causes this kind of problem. On the engine side, it could be aging ignition coils or clogged fuel injectors leading to insufficient power. The electronic throttle sensor is also crucial—if the signal is wrong, the ECU won’t deliver fuel. At the time, I told him to check if any warning lights were illuminated on the dashboard. If so, it’s best to use a diagnostic tool to read the specific trouble codes. For safety, don’t force the car to drive, especially on the highway—sudden loss of power is extremely dangerous. It’s safer to pull over and call a tow truck to take it to a professional repair shop. This model’s transmission is particularly delicate, so it’s best to change the fluid every 30,000 kilometers.
