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.

Verbatim excerpts from NHTSA complaints, by component

Electrical system

76 reports1 crash15 fires
“The contact owns a 2009 Buick Lucerne. The contact stated that while attempting to start the vehicle, the engine failed to turn over. No warning light was illuminated. The contact stated that upon inspection he became aware that one of the relays from the electric fuel pump under the rear passenger’s seat needed to be replaced. The contact stated that the fuel pump relay prong base had melted due to overheating. In addition, the contact stated that the fuse was a 10.01 AMP instead of a 5 AMP which could have caused the failure. The local dealer was not contacted. The vehicle was repaired; however, the failure reoccurred 2 days later. The manufacturer was made not aware of the failure. The failure mileage was approximately 66,000.”

Fuel/propulsion system

36 reports5 fires
“The car died suddenly and would not start, with no warnings or codes. Towed it to a Midas repair shop and it was diagnosed as a corroded Low Profile Fuel Pump relay. This was replaced, and the car ran fine for 3 days before going dead in the middle of driving and left me stranded in an intersection. Had to get it towed back to Midas where it was more accurately diagnosed that the issue with the relay was being caused by a faulty Rear Electrical Center. Both of these parts have been recalled, and I have only owned this car for a little over a year. It has only around 40,000 miles on it. Despite this recall, upon taking the car to the local Buick dealership, they stated they could not cover the recall due to it being expired before I even owned the car. I do not understand how it is right or fair for this to have to be paid out of pocket, for $183.53 and $818.81 respectively, when it is not my fault, it is a faulty GM parts issue, and GM stated they will not stand behind their product and cover the recall despite the evident risk to my safety if I was to continue driving the car without repair. I understand it is expired, but I fail to see how this is ethical…”
