Common Buick LaCrosse Problems

The LGX 3.6L V6 engine develops a persistent ticking noise from the high-pressure direct-injection fuel system, and the fuel injectors (part 12668393) fail to seat properly, causing fuel odor and lean condition codes P0171 and P0174.
The 9-speed automatic transmission (9T65) experiences a complete loss of forward gears intermittently due to internal wiring harness chafing against the transmission case, severing conductors to the shift solenoid pack.
The electronic automatic transmission range selector (E-shifter) on push-button-equipped models fails to register Park or Drive inputs, stranding the vehicle and requiring a BCM reset or tow to the dealer.
The mild hybrid eAssist system's lithium-ion battery pack loses capacity prematurely and fails to accept charge, disabling the auto start-stop function and triggering service hybrid system warnings with DTC P0A7F.
The front wheel speed sensors and tone rings corrode in states that use road salt, causing persistent ABS and traction control activation at low speeds and inaccurate speedometer readings above 60 mph.

Your California Lemon Law Rights

Under California's Song-Beverly Consumer Warranty Act, if your Buick LaCrosse has a substantial defect that cannot be repaired after a reasonable number of attempts, you may be entitled to:

  • Full refund of the purchase price
  • Replacement vehicle of comparable value
  • Cash compensation (cash-and-keep settlement)
  • Attorney's fees paid by the manufacturer

Buick LaCrosse Lemon Law FAQ

My Buick LaCrosse's 9-speed transmission intermittently loses forward gears. Is this dangerous enough for a California Lemon Law claim?

Yes. An intermittent loss of forward gears is an extremely dangerous safety defect that can leave you stranded in traffic without the ability to accelerate. Under the Song-Beverly Act, safety-related defects may require only two repair attempts to qualify the vehicle as a lemon. This type of transmission failure is one of the most compelling bases for a California lemon law claim.

Does the Song-Beverly Act cover my LaCrosse's eAssist hybrid battery failure?

Yes. The eAssist hybrid battery and its associated components are covered under the vehicle's powertrain and hybrid component warranty. Under the Song-Beverly Act, a battery failure that disables the hybrid system and causes warning lights is a substantial nonconformity. If the dealer cannot repair or replace the battery to restore full functionality, you may be entitled to a refund or replacement.

I have been making payments on my LaCrosse while it sits at the dealer for weeks. Can I recover those payments under California Lemon Law?

Yes. Under the Song-Beverly Act, if your vehicle qualifies as a lemon, you are entitled to a refund of all payments made, including monthly loan or lease payments, down payment, taxes, and registration fees. You may also recover incidental damages such as rental car costs and towing fees incurred while the vehicle was out of service.

The dealer fixed my LaCrosse's E-shifter once but it failed again six months later. Does this count as two repair attempts under California Lemon Law?

Yes. Each time the dealer attempts to repair the same defect, it counts as a separate repair attempt under the Song-Beverly Act, regardless of the time between visits. The fact that the E-shifter failed again after a prior repair demonstrates that the defect was not actually fixed. Two repair attempts for a safety-related shifter defect may be sufficient to establish lemon law presumption.
