Tire size: 235/55R17 99H In February 2022, I purchased a set of 4 Yokahama tires from Discount Tire Co., located at 2707 NW Loop 410, San Antonio, TX 78230. The mileage on the car was approx. 89,000. In February of 2024, my mechanic notice tread lifting on the tires, so I took the car to Discount Tire Co., located at 1755 SW Loop 410, San Antonio, TX 78227, and the service tech told me that I had not been rotating the tires property, which was what was causing this issue. I assured him that I had been rotating the tires. The tech said to let them rotate them again and the tire tread would "smooth out" over time. Mileage on the car at that time was approx. 118,000. In August of 2024, my mechanic again noticed the continued tread lifting on the tires. My mechanic stated that it appeared the tires had "dry rot". When I told him that Discount Tire had said it was from incorrect tire rotation, my mechanic said that what was happening to the tread could not possibly be from bad tire rotation. Further, he told me this type of tread lifting was dangerous for me to continue to drive on these tires. So, I took the car to Discount Tire Co., located at 3118 Goliad Rd., San Antonio, TX 78223. After explaining what my mechanic had just diagnosed, I requested the warranty that I purchased extra for all 4 tires be used to replace them. The manager at Discount Tire refused to replace my tires under warranty, which clearly appear to be defective. Mileage on the car at this point is approx. 126,000. The manager claimed they were not defective and safe to drive. I had him put this statement in writing prior to me leaving the store. The manager then offered to sell me a new set of tires for a discounted price of $800 +warranty cost for the 4 new tires. The manager refused to allow me to take MY "defective tires" with me for further analysis by another facility. I continue to drive on these Yokahama tires because they have been deemed "safe" by Discount Tire Co.

REAR PASSENGER FUSE BLOCK (P/N 19116816) GETS MELTED BY A FAULTY FUSE PUMP RELAY BURNING UP DUE TO A FAULTY DESIGN WITHIN THE FUEL PUMP SYSTEM. FUEL PUMP PUTTING A LOT OF RESISTANCE ON THE WIRING, RELAY WON'T BLOW, BUT IT MELTS. WITHOUT CORRECTING THIS, THE FUSE BOX WILL BE AFFECTED ONCE THE FUSE PUMP RELAY OVERHEATS AND EVENTUALLY MELTS AND BURNS. CAR WAS STATIONED. THIS IS UNSAFE BY ANY MEANS. THE FIRE COULD HAVE SPREAD AND CAUSED THE SEATS TO BURN AND WORSE, IT'S RIGHT BY THE GAS TANK.

2008 CADILLAC DTS (100K MI) WAS PARKED AND ENGINE WOULD TURN OVER BUT NOT START. I DETERMINED THAT THERE WAS NO FUEL TO ENGINE BY CHECKING SCHRADER VALVE ON FUEL RAIL. PROCEEDED TO CHECK FUEL PUMP (FP) FUSE (OK) AND FP RELAY (BURNED ON PIN 30 ALONG WITH FUSE BLOCK). REPLACED FP RELAY; HOWEVER, AFTER A FEW MINUTES FROM VEHICLE START, THE RELAY HEATS TO ABOUT 200 DEGREES F. AFTER READING SEVERAL FORUMS, THIS IS NOT UNCOMMON: IT APPEARS THE FUSE BLOCK (UNDER REAR SEAT ). IS DEFECTIVE. I HAVE ORDERED GM BLOCK 19116810 WHICH APPARENTLY SUPERSEDES THE ORIGINAL FACTORY GM BLOCK 13599106. THIS PROBLEM CLEARLY POSES MANY SAFETY ISSUES: FIRE, ENGINE SHUT DOWN WHILE DRIVING, ETC. GM NEEDS TO TAKE OWNERSHIP OF THIS PROBLEM. MOREOVER, I HAVE ALSO EXPERIENCED THE BURNED OUT CONNECTOR (UNDER PASSENGER SEAT) FOR THE HEATED SEATS. FORTUNATELY, I DID NOT HAVE THE HEATED WINDSHIELD WASHER OPTION WHICH ALSO EXPERIENCED ELECTRICAL ISSUES. SHAME ON GM FOR NOT CORRECTING THESE ENGINEERING DESIGN DEFECTS. SAFETY SHOULD BE PARAMOUNT WITH THESE TYPES OF ISSUES ON YOUR VEHICLES ESPECIALLY YOUR PREMIER BRAND (CADILLAC).

THE CHECK ENGINE CODE SHOWED THE INTERNAL POWER MODULE FAILURE CAUSED THE ENGINE TO SHUT DOWN WHILE TRAVELING AT A HIGH RATE OF SPEED. THIS WAS WITHOUT WARNING AND MADE THE CAR'S POWER BRAKES AND STEERING TO BECOME ALMOST IMPOSSIBLE TO STEER AND BRAKE THE CAR BY MY WIFE. I TOOK THE CAR TO THE DEALER WHO TOLD ME WITH THE CHECK ENGINE OFF THEY SAID I HAD TO DRIVE THE CAR UNTIL THE CHECK ENGINE LIGHT CAME BACK ON. WHILE DRIVING THE CAR THE CHECK ENGINE LIGHT CAME ON WHILE I WAS IN HEAVY TRAFFIC AND AGAIN AN ACCIDENT WAS NARROWLY AVOIDED. THE DEALER DID A DIAGNOSTIC CHECK AND REPLACED THE MODULE PLUS THE COMPUTER AT A COST OF $750. THIS IS THE NINTH CADILLAC I HAVE OWNED SINCE 1980 WHEN I PURCHASED A SEVILLE WITH A DIESEL ENGINE AND THIS IS THE FIRST THAT HAD A DEFECTIVE POWER MODULE AND COMPUTER. THIS WAS A SAFETY HAZARD AND BOTH CADILLAC AND I WERE LUCKY THAT THERE WAS NO ACCIDENT WITH INJURIES. NOW WITH THE PROBLEM CORRECTED MY WIFE IS HESITANT ABOUT DRIVING AFTER THE CLOSE CALL SHE HAS EXPERIENCED. SHE ALWAYS INSISTED ON DRIVING A CADILLAC BECAUSE OF THEIR SAFETY RATING AND BECAUSE THEY WON THE MALCULAM BALDRIDGE QUALITY AWARD BACK IN THE 1980'S. I THINK A RECALL TO REPLACE THOSE MODULES AFTER HIGH MILEAGE OF AT LEAST 65K MILES. MY 2008 CADILLAC DTS MILEAGE INDICATOR SHOWS 84,000 MILES.

TRIED TO START MY CAR AND IT WOULD TURN OVER BUT NOT CRANK. REPLACED THE FUEL PUMP AND FUEL PUMP RELAY. CAR STARTED AND I DROVE ABOUT 10 MILES AND IT CUT OFF WHILE DRIVING. SINCE WE REPLACED THE RELAY MY HUSBAND TOOK OUT THE BACK SEAT TO CHECK IT TO FIND THE FUSE BOX TOO HOT TO TOUCH AND SMELLED LIKE BURNING WIRES. HE DISCONNECTED THE BATTERY TO AVOID A FIRE. THIS COULD HAVE BEEN A DISASTER HAD HE NOT HAD THE FORETHOUGHT TO CHECK THE FUEL RELAY. IT WAS JUST BEFORE CAUSING A FIRE AND WE HAD TWO PASSENGERS IN THE BACK SEAT.

I AM FORCED TO INSTALL A NEW ENGINE BECAUSE THE PROBLEM IS SO COSTLY TO RESOLVE. APPROXIMATELY $4,500. IS THERE ANY CLASS ACTION AGAINST CADILLAC OR IS THERE ANY RELIEF AVAILABLE.

THE DASH LIGHTS ARE INTERMITTENT, OR VERY DIM. THE BRIGHTNESS DOES NOT COME ON FOR MILES AT A TIME. YOU CANNOT SEE THE SPEEDOMETER TO SEE HOW FAST YOU ARE GOING. IT IS A SAFETY ISSUE. IN MOTION, CITY STREETS AND ON THE HIGHWAY. HAVE REPORTED THIS TO CADILLAC AND HAVE HAD IT TO THE CADILLAC DEALER. THEY SAY THERE IS NOTHING WRONG. I HAVE HAD IT TO EARNHARDT CADILLAC SCOTTSDALE, AZ. SO FAR NO FIX. THIS HAS BEEN GOING ON FOR YEARS. AFTER THE WARRANTY STOPPED I DID NOT GO BACK TO DEALER.
