Common Buick LaCrosse Problems by Model Year

2005–2009 Buick LaCrosse (First Generation)

These models came with reliable V6 engines, but a few age-related problems have become common. 

  1. Transmission Slipping
    By the time they hit 100,000 miles, many of these cars began showing signs of transmission wear—especially slipping between gears.
  2. Intake Manifold Gasket Leaks
    The plastic gaskets used in 3.8L engines often ended up cracking. When that happened, coolant could leak into the engine, leading to overheating.
  3. Steering Clunk
    A knocking or clunking sound when turning is usually a worn intermediate steering shaft. Sometimes it just needs lubrication—other times, replacement.

2010–2013 Buick LaCrosse (Second Generation)

This round of models brought in sleeker styling and more technology—but also a few trouble spots. 

  1. Timing Chain Wear
    The 3.6L V6 engines in these years sometimes suffered from timing chain stretch earlier than expected. It usually showed up as poor performance or a check engine light.
  2. Electrical Gremlins
    Unresponsive infotainment screens, flickering gauges, or odd warning messages often pointed to faulty body control modules or weak electrical grounds.
  3. ABS & Stabilitrak Problems
    If the traction or ABS lights are stuck on, the issue is typically a bad wheel speed sensor or a damaged wire harness.

2014–2016 Buick LaCrosse (Mid-Cycle Refresh)

These models received style upgrades and interior refinements, but not all the bugs were gone. 

  1. Power Steering Loss
    Some drivers experienced sudden loss of electric steering assist—especially when temperatures dropped. GM issued recalls for some affected vehicles.
  2. Infotainment Freezes
    The touchscreen would occasionally lock up or go blank. In a few cases, the entire head unit had to be replaced.
  3. Interior Rattles
    Cabin trim around the dash and doors was known to creak or buzz over time, particularly in extreme weather.

2017–2019 Buick LaCrosse (Final U.S. Models)

These final-generation LaCrosses were stylish and efficient—but still had a few quirks to work out. 

  1. Jerky 9-Speed Transmission
    Some drivers noticed lurching or hesitation, especially at lower speeds. A software update helped in some cases, but others required mechanical repairs.
  2. Auto Start/Stop Glitches
    The engine wouldn’t always restart properly at stoplights. The issue often stemmed from battery sensor problems or outdated firmware.
  3. Battery Drain
    A few models developed parasitic battery drain—when onboard systems stay awake after the car is off, slowly draining the battery.
