Crash ratings
NHTSA's stars out of five, for each version it tested. Front crash stars only compare cars of about the same size and weight. The tests changed for 2011 models, so these stars do not line up with newer ones.

Lights
Apr 7, 2009 · Recall 09E012000
Sabersport is recalling 16,270 combination corner and bumper lamp assemblies of various part numbers sold for use as aftermarket equipment for various passenger vehicles. These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "lamps, reflective devices, and associated equipment." these lamps do not contain the required amber side reflectors.
What can happen
Decreased lighting visibility may result in a vehicle crash.
The fix
Sabersport will notify owners and offer a full refund for the noncompliant combination lamps. The safety recall began on may 11, 2009. Owners may contact sabersport at 1-909-598-7589.
Fuel system
Feb 24, 2004 · Recall 04V090000
On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. If the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire.
What can happen
The backfire can rupture the intake manifold. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire.
The fix
Dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on june 30, 2004, and phase 2 began on september 30, 2004. Owners should contact buick at 1-866-608-8080, oldsmobile at 1-800-630-6537, or pontiac at 1-800-620-7668.
Transmission and drivetrain
Apr 26, 1999 · Recall 99V089000
Vehicle description: passenger vehicles equipped with 4t65e automatic transmissions. These vehicles fail to conform to the requirements of fmvss no. 102, "transmission shift lever sequence." a retaining clip, which secures the manual valve to the linkage of the transmission detent lever, can become loose under a combination of possible driver shifting maneuvers and allow the link to become disconnected from the manual valve.
What can happen
If the link disconnects, the driver's indicated prndl state may differ from the hydraulic state of the transmission. If the driver selects 'drive' and the transmission is actually in 'reverse', a vehicle crash could occur.
The fix
Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener.
Wheels and tires
Apr 12, 1999 · Recall 99V072000
Vehicle description: passenger vehicles equipped with chrome plated aluminum wheels. Some of these wheels have a mounting surface that was not machined correctly, causing the wheel studs to break.
What can happen
The tire/wheel assembly could separate from the vehicle, increasing the risk of a crash.
The fix
Dealers will inspect the wheels and replace all wheels with date codes indicating that they may not have been machined correctly. The wheel mounting studs at any location where a suspect wheel was installed will also be replaced.
