NHTSA's VIN data lists these trims for the 2007 Lucerne. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 164 complaints with NHTSA about the 2007 Lucerne. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 4 recall campaigns for the 2007 Lucerne over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Risk: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.
GM IS RECALLING CERTAIN MODEL YEAR 2006-2009 BUICK, LUCERNE; CADILLAC DTS; HUMMER H2; MODEL YEAR 2008-2009 BUICK ENCLAVE; CADILLAC CTS; MODEL YEAR 2007-2009 CADILLAC ESCALADE, ESCALADE ESV, ESCALADE EXT; CHEVROLET AVALANCHE, SILVERADO, SUBURBAN, TAHOE; GMC ACADIA, SIERRA, YUKON, YUKON XL; SATURN OUTLOOK; AND MODEL YEAR 2009 CHEVROLET TRAVERSE VEHICLES EQUIPPED WITH A HEATED WASHER FLUID SYSTEM (HWFS). A RECALL WAS IMPLEMENTED IN 2008 TO ADD A FUSE TO THE CONTROL CIRCUIT HARNESS TO ADDRESS THE POTENTIAL CONSEQUENCES OF A PRINTED CIRCUIT BOARD (PCB) ELECTRICAL SHORT. HOWEVER, THERE HAVE BEEN NEW REPORTS OF THERMAL INCIDENTS ON HWFS MODULES AFTER THIS IMPROVEMENT WAS INSTALLED. THESE INCIDENTS RESULTED FROM A NEW FAILURE MODE ATTRIBUTED TO THE DEVICE'S THERMAL PROTECTION FEATURE. THE SIGNIFICANCE VARIES FROM MINOR DISTORTION TO CONSIDERABLE MELTING OF THE PLASTIC AROUND THE HWFS FLUID CHAMBER.
Risk: IT IS POSSIBLE FOR THE HEATED WASHER MODULE TO IGNITE AND A FIRE MAY OCCUR.
Remedy: DEALERS WILL PERMANENTLY DISABLE AND REMOVE THE HEATED WASHER FLUID MODULE. AN UPDATED PAGE FOR THE OWNER MANUAL WILL BE PROVIDED AND INSERTED IN THE OWNER MANUAL TO DOCUMENT THAT THE FEATURE HAS BEEN PERMANENTLY DISABLED AND REMOVED FROM THE VEHICLE. THE SAFETY RECALL BEGAN ON JUNE 11, 2010. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, SATURN AT 1-800-972-8876, GMC AT 1-866-996-9463 AND HUMMER AT 1-800-732-5493 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.

A SHORT CIRCUIT ON THE PRINTED CIRCUIT BOARD FOR THE WASHER FLUID HEATER MAY OVERHEAT THE CONTROL-CIRCUIT GROUND WIRE.
Risk: THIS MAY CAUSE OTHER ELECTRICAL FEATURES TO MALFUNCTION, CREATE AN ODOR, OR CAUSE SMOKE INCREASING THE RISK OF A FIRE.
Remedy: DEALERS WILL INSTALL A WIRE HARNESS WITH AN IN-LINE FUSE FREE OF CHARGE. THE RECALL BEGAN ON SEPTEMBER 12, 2008. OWNERS MAY CONTACT BUICK AT 1-866-608-8080; CADILLAC AT 1-800-982-2339 OR HTTP://WWW.CADILLAC.COM; CHEVROLET AT 1-800-630-2438; SATURN AT 1-800-972-8876 OR HTTP://WWW.SATURN.COM, GMC AT 1-866-996-9436; OR HUMMER AT 1-800-732-5493; OR THROUGH THEIR WEBSITE AT <A HREF=HTTP://WWW.GMOWNERCENTER.COM>HTTP://WWW.GMOWNERCENTER.COM</A> .
CERTAIN VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 118, 'POWER OPERATED WINDOW, PARTITION, AND ROOF PANEL SYSTEMS.' UNDER THE STANDARD, THE SUNROOF MAY ONLY BE CLOSED WHEN THE IGNITION IS ON, OR AFTER THE IGNITION IS TURNED OFF, BUT BEFORE EITHER OF THE FRONT DOORS ARE OPENED. THE AFFECTED VEHICLES MAY EXHIBIT A CONDITION WHERE THE SUNROOF CAN BE CLOSED AFTER THE IGNITION IS TURNED OFF AND THE DOORS ARE OPENED.
Risk: THIS STANDARD SPECIFIES REQUIREMENTS FOR POWER OPERATED WINDOW, PARTITION, AND ROOF PANEL SYSTEMS TO MINIMIZE THE LIKELIHOOD OF DEATH OR INJURY FROM THEIR ACCIDENTAL OPERATION.
Remedy: DEALERS WILL INSTALL A WIRE HARNESS. THE RECALL BEGAN ON MAY 29, 2008. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.

The parts they mention most: equipment (387), electrical system (181), engine and engine cooling (87), equipment adaptive/mobility (59), power train (56).
NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
The owner's manual gives the oil and how often to change it. We show oil facts only once we've checked them against the manual, and we haven't yet for the 2007 Lucerne.
