2008 CADILLAC CTS Fuel/propulsion System Problems

Ever since I purchased this 2008 CTS vehicle, I have dumped thousands of dollars to repair the vehicle even after the "recall repairs". Problems persist and the car has become more dangerous than ever. The vehicle had inspected by the dealership a number of times the first 5 years of ownership the first 3, listed below, were the replaced recalls from dealership, the rest are known safety issues that gm denies to admit to faults and recalls. *Ignition starter replacement (still have starter failure issues after 2 repairs from gm) *washer fluid warmer removal (they just snipped the wires and removed the component but left hot wires exposed in vehicle) *motherboard ecm replacement recall(ecm is still faulty and has caused dozens of electrical issues. **************** battery drains over night. On my 6th battery (just bought new one 3 days ago) gauge cluster never recalibrated and is completely disabled. Don't know how fast im going how much gas or any other info related to. sunroof constantly leaking, flooding vehicle and destroying the electrical components which fried many relays including the door lock and power window components vehicle refuses to turn but cranks on fuel often will not allow a fill up ecm throwing irrelevant codes headlight failure due to seal defect that allows moisture into headlight casing frequent oil loss. 2018: vehicle engine failure whilst driving on freeway with zero warning nearly causing a fatal crash. Purchased new alternator (Shade tree auto in san Clemente) and had to pay 2000 for tow and alternator transmission failure and near miss collision into another vehicle on a steep incline road I have taken this vehicle to a multitude of repair shops and auto supply to get a diagnosis. Even the dealership didn't have any answers. Now I am out of a car. and money. These issues had been confirmed by Rorick Cadillac, Shade tree auto, oreily, s and s auto, auto zone.

Fuel supply stops and engine stalls when I get near or below 1/4 tank. I can restart the engine and it will run for anywhere from a few seconds to sometimes a minute, but mostly only a few seconds. Limp my car this way to a gas station, fill the tank, problem solved. I know it had fuel in the tank as it only took 11 gallons with my 16 gallon tank. Installed a new fuel pump, problem continues. This can put someone in a life threatening situation. The first time it happened I was passing a semi truck on a 2 lane Interstate with cars and trucks behind me. Just as I got half way on the semi's left, I'm doing about 70 mph, the engine stalls. Luckily, I kept a cool head and turned on my blinker as the car slowed down. The semi behind me took a hint and backed off so I could coast to the right shoulder. This could very easily have caused a fatal accident. It has since happened 3 or 4 other times.

THE CAR ONLY HAS 35000 MILES ON IT. THE ENGINE MISFIRES CONSTANTLY WHEN GIVING GAS ESPECIALLY IF YOUR GOING UP HILL AND THERE IS MORE LOAD ON THE VEHICLE. AFTER I HAD $5000 WORTH OF WORK TO FIX THE PROBLEM AT A CADILLAC DEALERSHIP. THEY COULDN'T FIX THE ISSUE SO THEY CAME BACK AND SAID THAT WE NEEDED A NEW ENGINE. WE TOLD THEM OVER AND OVER AGAIN THAT WE DON'T THINK IT'S THE ENGINE BUT THEY GUARANTEED US THE NEW ENGINE WOULD FIX THE PROBLEM. SO ANOTHER $5000 LATER AND STILL NOT FIXED. THE VEHICLE IDLES FINE, IT ONLY HAPPENS WHILE DRIVING. THE CHECK ENGINE LIGHT EVENTUALLY COMES ON INDICATING MISFIRES IN 2 CYLINDERS

FEBRUARY 14, 2020 IS JUST THE LAST DATE IT HAS HAPPENED ON. IT'S HAPPENED APPROXIMATELY 30 TIMES. FOR THE PAST TWO YEARS IF YOU DON'T JUST EASE ON THE GAS THE REDUCED ENGINE LIGHT AND TRACTION CONTROL LIGHT COMES ON AND THE CAR WILL NOT GO OVER 5 M.P.H. I HAVE READ SEVERAL HUNDRED ARTICLES ONLINE ON DIFFERENT WEBSITES WITH PEOPLE DESCRIBING THE EXACT SAME THING. IT ALMOST GOT ME HIT ON THE MS. RIVER BRIDGE THE OTHER DAY. IF U HAVE TO GO UP ANY TYPE OF INCLINE IT DOES IT ALSO. I WAS ACCELERATING SLOWLY AS I POSSIBLY COULD GOING UP THE SMALL INCLINE ON THE BRIDGE THAT CONNECTS LOUISIANA AND MISSISSIPPI. ALL OF A SUDDEN THE REDUCED ENGINE POWER LIGHT CAME ON AND I COULD NOT GET OUT OF TRAFFIC THAT WAS DOING APPROXIMATELY 55 M.P.H. AND MY TWO YEAR OLD GRANDSON WAS IN THE BACKSEAT. THE ONLY WAY TO FIX IT TEMPORARILY IS TO GET OFF THE BRIDGE BECAUSE THERE IS NO WHERE TO PULL TO THE SIDE OF THE BRIDGE. YOU HAVE TO KILL THE CAR FOR A FEW SECONDS AND RECRANK IT. I'VE HAD MECHANICS LOOK AT IT AND I'VE HAD IT HOOKED TO THE COMPUTER AT O'REILLYS. NO ONE CAN TELL ME ANYTHING. BUT IF IT WEREN'T A SAFETY RECALL WHY WOULD ALMOST 1,000 VEHICLES THAT I KNOW OF BE DOING THE SAME THING. YOU CAN GOOGLE IT AND SEE THAT I'M TELLING THE TRUTH. LOTS OF THESE CARS HAVE THE IDENTICAL PROBLEM. I'M CURRENTLY LOOKING FOR A NEWER MODEL BETWEEN 2014-2018, BUT I'M AFRAID OF HAVING THE SAME OR A SIMILAR PROBLEM. THIS IS DEFINITELY A RECALL. BUT IT SEEMS TO ME THAT YOU ALL DO NOT WANT TO DO ANY RECALLS ON THESE CADILLACS. I'VE BEEN TO LOTS AND LOTS OF WEBSITES AND I HAVE NOT FOUND ANYONE WHO'S BEEN ABLE TO FIGURE OUT THE PROBLEM. EVEN THE ONES THAT HAVE HAD IT PUT IN THE DEALERSHIP HAVE STILL YET TO FIGURE OUT THE PROBLEM. IT HAS TO BE ELECTRICAL OR ONE OR MORE SENSORS MALFUNCTIONING. THANK YOU FOR YOUR TIME.

14V542000 WAS A RECALL ON 2004-2007 CADILLAC CTS FOR FUEL LEAK ABOVE THE TANK. THIS 2008 MODEL HAS THE VERY SAME/SIMILAR LEAK AND IS NOT INCLUDED IN THE RECALL? WHY NOT? SAME PROBLEM, VERY DANGEROUS. NUMEROUS COMPLAINTS IT LOOKS LIKE IF YOU SEARCH INTERNET ABOUT THE 2008 CADILLAC CTS FUEL LEAK.

THE PROBLEM STARTED WITH THE TIMING CHAIN, WHICH LED TO COIL ISSUES AND CATALYTIC CONVERTERS ISSUES WHICH LED TO LOW HEAD BEAMS CONSTANTLY BURNING OUT. EVERYTIME WORK IS DONE IT CAUSES A CHAIN REACTION TO OTHER PARTS IN THE CAR THAT REQUIRES MORE AND MORE MONEY. NOW THE ENGINE LIGHT IS STILL ON AND I AM TOLD THAT SINCE THE FIRST CATALYTIC CONVERTER WAS REPAIRED, THE SECOND ONE NOW NEEDS REPLACING AND THE LOW HEAD BEAM ON THE PASSENGER SIDE HAS WIRING ISSUES THAT WILL NOT ALLOW THE NEW BULB TO BURN, I AM TOLD THAT THE WIRING APPEARS TO BE SPLICED. THE CATALYTIC CONVERTER WAS REPLACED IN APRIL AND SO WAS THE LOW BEAM BULB. HEADLIGHT WAS REPLACED IN APRIL, 2015 IT IS NOT WORKING TODAY AND WAS TOLD BY DEALERSHIP THAT THE WIRING HAD BEEN SPLICED OR BURNED OUT. RADIO SPEAKERS DO NOT WORK AND ALL WAS CENTERED AROUND ISSUES WITH COILS AND CATALYTIC COVERTERS.

THE FUEL PUMP FUEL FEED LINE HAS DEVELOPED A LEAK AND IS SPRAYING FUEL CREATING A FIRE HAZZARD. ON TOP OF THE TANK SITS THE FUEL PUMP. ON THE FUEL PUMP THE FEED TUBE CONNECTS TO THE FUEL LINE WHICH THEN GOES TO THE ENGINE. THIS LEAK CREATED A FUEL ODOR AND GOT PROGRESSIVELY WORSE. I FOUND DAMPNESS ON TOP OF THE TANK, WHICH WAS GASOLINE. UPON MY FURTHER INVESTIGATION I NOTICED THE FUEL SPRAYING OUT OF A PIN HOLE SIZED CRACK. THIS IS SIMILAR TO A RECALL ISSUED ON OTHER GM VEHICLES IN THE PAST AND I FEEL THE CADILLAC CTS SHOULD BE INCLUDED. I'VE NOTICE OTHER PEOPLE HAVING THE SAME ISSUES VIA AN ONLINE SEARCH AT CADILLAC WEB FORUMS. I PERFORMED THE REPAIR MYSELF BUT IT IS A VERY LABOR INTENSIVE AND EXPENSIVE REPAIR FOR A NON CAPABLE PERSON IF DONE BY A DEALER OR REPAIR SHOP. WE ARE TALKING ABOUT A 6 HOUR JOB BECAUSE THE REAR FRAME, DIFFERENTIAL, EXHAUST ETC MUST BE REMOVED TO ACCESS THE GAS TANK. A MAJOR ISSUE AND SAFETY RISK IN MY VIEW. THE LEAK WILL OCCUR WHENEVER THE CAR IS ON AS WELL AS OFF SINCE THE FUEL SYSTEM IS UNDER PRESSURE. WHEN CAR WAS PARKED - MY GARAGE SMELLED LIKE GAS THE LEAK WAS SO BAD. ** I HAVE PHOTOS AND VIDEO AND WILL UPLOAD AT A LATER TIME. ** THIS CAR IS A PERFECTLY MAINTAINED VEHICLE AND STILL APPEARS BRAND NEW - NO ABUSE OR OTHER ISSUES CAUSED THIS DEFECT IN THE FUEL PUMP MODULE.

FORTUNATELY, WE WERE AT A STANDSTILL IN THE MIDDLE OF THE ROAD AND THE CAR RESTARTED, WENT TO GAS STATION, FILLED THE CAR WITH GAS, IT TOOK 14.7 GALLONS, THE CTS GAS CAPACITY IS 18 GALLONS. DEALER DOESN'T KNOW WHAT THE PROBLEM IS. JUST WAITING FOR A SOLUTION. THIS IS A MAJOR SAFETY CONCERN THAT NEEDS IMMEDIATE ATTENTION. *TR

I WAS TRAVELING AT 25MPH WHEN THERE WAS A SUDDEN VERY LOUD EXPLOSIVE/GRINDING NOISE(IT BROUGHT PEOPLE RUNNING OUT OF ADJACENT BUILDINGS). I HIT MY BRAKES IMMEDIATELY, BUT THE NOISE CONTINUED UNTIL I PUT IT INTO PARK. I EXITED THE CAR AND UNDER THE REAR AXLE OF MY VEHICLE WERE MULTIPLE LARGE BOLTS AND SCREWS LINED UP IN A ROW. THE VEHICLE WAS TOTALLY DISABLED, AND SUBSEQUENTLY WAS TOWED TO THE DEALER. THEY DETERMINED THAT ALL THE REAR AXLE BOLTS JUST FELL OUT AT ONCE.THERE WAS NO OTHER DAMAGE FOUND TO THE VEHICLE. MY CONCERNS REMAIN AS TO "WHY DID THIS HAPPEN" AND "WHAT IF I HAD BEEN GOING AT AN ACCELERATED RATE OF SPEED"? MULTIPLE EXPERIENCED MECHANICS AND SPECIALIST (INCLUDING CADILLAC) HAVE NO ANSWERS TO THESE QUESTIONS AND HAVE NEVER SEEN THIS HAPPEN BEFORE. *TR
