2005 Buick Lacrosse CX misc. issues

Well last year my aunt purchsed a silver 2005 Buick Lacrosse CX with the 3.8L engine. Everything ran good through the winter and it handled well with the Traction Control and ABS. I only noticed one problem and it was a sqeaking noise coming from the center console. It would make the noise whenever i accelerated or slowed down or when ever the car moved up or down. Havent checked it out yet but i plan to. Another issue I am having is with the transmission. The first time it happened was when i was accelerating onto the highway. It changed into second good and as i reached 40 mph the car started hesitating and jumping. The car seemed to have lost power between 2nd and 3rd gear. I let off the gas pedal and accelerated again and it was okay. Now just today after leaving the mall i turned onto the highway and it did it again. I was taking off kind of fast and it shifted into 2nd fine. Then as it reached 45mph it started hesitating. I looked at rpms and it started jumping between 2000 and 3000. I was waiting for REDUCED ENGINE POWER to turn on but nothing. Not even SES light.Does anyone have any ideas?


Mike

Re: 2005 Buick Lacrosse, brakes/traction problem

I own a 2005 Buick Lacrosse. I have had steering problems, transmission clutch. And, now an ongoing problem with the brake/traction active light.
When parking or backing up slowly, my brakes "grab" and make a loud noise, then the traction active light appears. It has been at the dealership 4 times in the past 4 months for this and nothing is fixed yet!

Has anyone heard of this problem with the LaCross?

Thanks for any help. This is frustrating.

You probably have the LaCross transmission problem fixed by now. Mine did that and it was the transmission clutch. Now I have other issues with mine.

Re: 2005 Buick Lacrosse CX misc. issues

actually i didnt get the transmission problem fixed yet and now when i take sharp turns and push the gas pedal there is a small whining noise. so i checked the transmission fluid and level and theyre both fine. i also had problems with the abs and trac it was a bad speed sensor.
