Is the Transmission of the 2009 LaCrosse Bound to Fail?
3 Answers
The transmission of the 2009 LaCrosse is not bound to fail. Here is an introduction to the LaCrosse: 1. 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 light curtain illumination effect. With a body length of 5026mm, width of 1866mm, height of 1462mm, and an ultra-long wheelbase of 2905mm, it provides a spacious driving and riding space for mid-to-large luxury sedans, offering a comfortable and free riding posture. The interior features 29 practical storage spaces, making it convenient to store commonly used devices and handbags. 2. Powertrain: The 2021 Buick LaCrosse family is equipped with two sets of driving systems, combining powerful performance with excellent fuel economy, and all models meet the 'China VI b' emission standards. At the same time, different power combinations will meet users' diverse needs with richer choices and further enhance the competitiveness of the Buick LaCrosse in the mid-to-high-end car segment.
I've been driving for over a decade and have frequently dealt with the 2009 LaCrosse. Its transmission isn't guaranteed to fail, but it does have quite a few issues, especially the 4T65E model which is prone to overheating leading to shift shuddering or delays. Many owners complain about sudden jerking while driving, likely due to seal aging or solenoid valve failure. I recommend changing the transmission fluid every 30,000 kilometers – this can significantly extend its lifespan. I've personally helped friends repair several older cars without issues, the key is proper maintenance without cutting corners. If you often drive aggressively or skip fluid changes, the risk increases, but regular inspections can avoid major repairs. When buying used, pay special attention to the transmission's service history.
I've been driving a 2009 Buick LaCrosse for several years, and the transmission has never failed me—it's been quite reliable. However, some of my friends' cars have had issues, like sluggish shifting or slipping, likely due to the common problem of aging control modules in this model. With regular maintenance, it generally holds up well. I always have the mechanics check the fluids and wiring during service. Neglecting it can indeed lead to trouble, as my neighbor's car once required major repairs. But based on my experience, driving gently and avoiding sudden acceleration helps keep the transmission stable in most cases, so there's no need to worry too much.
