2007 Chevrolet Suburban Engine

As the current investigation is going for the General Motors engines 2014-2025 5.3L and 6.2L for AFM/DFM. The same is happening with 2007 - 2014 5.3L engines with DOD. I had a 2014 Chevy Suburban with the 5.3L I had to rebuild the passenger side due to a DOD lifter failing. My current, 2007 Suburban is starting to make a DOD lifter tap, again on the passenger side. I will be getting a full rebuilt engine with the DOD system deleted to prevent this in the future. Hundreds have had this happen in the car forums and I can not imagine how many have encountered the same issue but do not say anything due to chalking it up to mileage, age of the vehicle, or just accepting the failure by design. Most are simply taking it on the chin; paying out of pocket or doing the work themselves to repair, delete, or modify the engines. I understand there is time and the age of the vehicles against these claims, but acknowledgement and shedding light on this known issue from General Motors will help just as much.

The contact owns a 2007 Chevrolet Suburban. The contact stated while driving 50-60 MPH, the check engine warning light illuminated, and the vehicle started jerking. Additionally, the contact noticed that there was white smoke coming out of the exhaust pipe. The vehicle was taken to Triple A service station, where the cause of the failure could not be determined; however, unknown plugs and wire were replaced. The contact stated that the failure recurred several times while driving. The vehicle was taken to an independent mechanic, where flour coil packs were replaced; however, the failure persisted. The vehicle was taken to the local dealer, where it was diagnosed that intake lifter of cylinder #1 was not moving due to a collapsed lifter roller, which lead to oil built up on the oil pan and the rear main seal. The dealer determined that engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 185,000.

The engine has a collapsed lifter that has failed. This problem is placing us at risk of breaking down while driving. I live in a busy city that has a lot of traffic. When I have money, I plan to take the vehicle to the dealership to confirm. I first noticed the problem by hearing the engine make a clicking sound when the engine is running. The sound is coming from the area of lifter location.

The engine began smoking really bad when driving down highway and car locked down. It became undriveable. I was out of town when happened and had to have towed. Mechanic confirmed motor is bad and has to be replaced. Just had transmission replaced 2 weeks prior to this happening. Transmission has had to be replaced 2 x's since I have owned vehicle.

ACTIVE FUEL MANAGEMENT (AFM) LIFTERS JAM/SEIZE CAUSING PUSH RODS TO REMAIN COLLAPSED AND CAUSING ENGINE MISFIRES THROUGHOUT THE ENGINE AND EXCESSIVE OIL BURNING, POSSIBLE DAMAGE TO CATALYTIC CONVERTERS, AND PREMATURE ENGINE WEAR. LIFTERS MUST BE REPLACED OR ENGINE REPLACED. I WAS DRIVING THE CAR AND WHEN THE ENGINE BEGAN MISFIRING, CHECK ENGINE LIGHT BEGAN BLINKING, TRACTION CONTROL BECAME DISABLED, AND ERROR ON DASH SAYING SERVICE STABILITRAK AND TRACTION CONTROL DISABLED APPEARED. THE CAR BEGAN TO SHIFT ERRATICALLY SHAKING AND LUNGING.

ENGINE IS MALFUNCTIONING AND USING EXCESSIVE AMOUNTS OF OIL (1 QUART EVERY 1-2 WEEKS). THE MANUFACTURER BUILT BAD MOTORS IN 2007 AND KNOWINGLY COVERED IT UP. THE VEHICLES WERE STILL SOLD TO CONSUMERS AND RATHER THAN FIXING THE ISSUE (ENGINE WOULD HAVE TO BE REBUILT OR REPLACED) THE MANUFACTURER IS PLACING ALL RESPONSIBILITY AND COST ($9,000 FIX) ON THE CONSUMER, EVEN WHEN REPORTED BEFORE 100,000 MILES. THE MANUFACTURER KNOWINGLY SOLD LEMON VEHICLES AND REFUSES TO FIX.

TL* THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN 1500. WHILE DRIVING 45 MPH, THE CHECK ENGINE, STABILITRAK, AND STOP ENGINE NOW WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO COURTESY CHEVROLET (LOCATED AT 1220 E STONE DR, KINGSPORT, TN 37660, (888) 320-1411) TO BE DIAGNOSED, BUT THE MECHANIC WAS UNABLE TO PROPERLY DIAGNOSE THE VEHICLE. THE CONTACT STATED THAT THE SPARK PLUGS, IGNITION WIRE, AND OIL SENDING UNIT WERE REPLACED; HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 156,000.

I WAS DRIVING ON A CITY STREET AND MADE A RIGHT TURN ONTO ANOTHER CITY STREET AND THE ENGINE STARTED RUNNING ROUGH AND IDLE ROUGH, SERVICE STABILITRAK LIGHT STAYED ON, SERVICE TRACTION CONTROL, TRANSMISSION JERKS FROM 1ST GEAR TO 2ND GEAR, ENGINE TICKING/KNOCKING, SERVICE ENGINE LIGHT FLASHING, SCAN CODE CAME UP AS MISFIRE ON CYLINDER #4, TOOK VEHICLE TO REPAIR SHOP AND LIFTERS WERE REPLACED AMONG OTHER THINGS; SEE ATTACHED FILES.

THE MANUFACTURER KNOWINGLY SOLD LEMON VEHICLES AND REFUSES TO FIX. A MECHANIC TOLD ME THAT MY ENGINE COULD EXPLODE (SEVERE SAFETY ISSUE).

WE HAVE A 2007 SUBURBAN WITH THE 5.3L ENGINE. AFTER, MUCH RESEARCH ON THE INTERNET, MY WIFE AND I HAVE FOUND THAT THERE EVIDENTLY IS A DESIGN FLAW WITH THE AFM LIFTERS. OUR VEHICLE DOES HAVE MILES, BUT SINCE THIS EVIDENTLY IS A VERY COMMON PROBLEM, WE DID THINK CHEVROLET WOULD AT LEAST OFFER SOME ASSISTANCE WITH THE REPAIR. A LIFTER COLLAPSED AND THE COST TO REPLACE THE LIFTERS IS $3,500.00, PLUS TAX AT TOM GILL CHEVROLET IN FLORENCE, KY. I DON'T BLAME THE DEALER FOR THIS, BUT CHEVROLET HAS REALLY DROPPED THE BALL ON THIS ISSUE FOR MANY, MANY VEHICLES WITH THE SAME ISSUE. SOMETHING SHOULD BE DONE TO BETTER PROTECT THE CONSUMER.

MY VEHICLE WAS HAVING TROUBLE STARTING AND IDLING ROUGH. I BROUGHT IT IN FOR REPAIRS AND WAS TOLD IT NEEDED A NEW FUEL PUMP AND AIR FILTER. I HAD THOSE CHANGED IN TOTAL SPENDING $1700. THREE DAYS LATER, THE CHECK ENGINE LIGHT STARTED FLASHING IN MY CAR. I COULD FEEL THE ENGINE MISFIRING AND WAS LOSING POWER. THE OIL PRESSURE WAS FLUCTUATING RAPIDLY. I DROVE IT BACK TO MY HOME AND HAD IT TOWED TO THE DEALERSHIP. I WAS TOLD THAT THE CYLINDER 4 WAS MISFIRING CAUSED BY THE CYLINDER DEACTIVATION FAILURE WHICH IS CAUSED BY THE AUTOMATIC FUEL MANAGEMENT SYSTEM. THIS IS CAUSING THE LIFTER TO FAIL.

TL* THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN. WHILE DRIVING 15 MPH, THE ENGINE STALLED WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 190,000.

EXCESSIVE OIL CONSUMPTION. 1 MONTH OF DRIVING IS EQUAL TO 2-3 QUARTS OF OIL REPLACEMENT.

CONSUMPTION OF OIL DUE TO THE STUCK RING AND BEEN COMPLAINING SINCE I HIT 100K MILES THE DEALER JUST GAVE ME THE RUN AROUND.

THE TRUCK USES A QUART OF OIL EVERY 1000-1500 MILES. THIS IS NOT GOOD FOR THE ENVIORNMENT OR MY WALLET.

CHEVROLET SUBURBAN HAVE A PROBLEM WITH EXCESSIVE OIL BURNING. AND NOT DOING ANYTHING ABOUT IT.

I BOUGHT THIS SUBURBAN USED IN 2010 WITH ABOUT 32,000 MILES ON THE ODOMETER. I AM THE 2ND OWNER. FROM THE DAY I BOUGHT IT, IT HAS BURNED OIL. THE ADD OIL LIGHT COMES ON HALF WAY THROUGH A OIL CHANGE. IT'S MY 3RD SUBURBAN. NEITHER OF THOSE TWO HAD EVER BURNED OIL. IT WAS STILL UNDER FACTORY WARRANTY, SO I TOOK IT TO COURTESY CHEVROLET IN PHOENIX. THEY PUT IT ON A OIL WATCH. I HAD TO BRING THE TRUCK BACK IN EVERY THOUSAND MILES SO THEY COULD CHECK THE BURN RATE. THEY ALWAYS SAID IT WAS NORMAL PER CHEVY BURN RATES. REALLY? CHECK THE INTERNET FOR 2007 CHEVROLET ENGINE OIL, HIGH BURN RATES AND YOU WILL SEE THAT MINE IS NOT THE ONLY ENGINE THAT BURNS OIL. IT SOUNDS LIKE CHEVROLET KNEW THERE WAS A PROBLEM, AND INSTEAD OF FIXING THE PROBLEM WITH INTEGRITY, THEY CHANGED THEIR BURN RATES SO THEY WOULDN'T HAVE TO. I HAVE LOST ALL FAITH IN CHEVROLET. I WILL NEVER BUY ANOTHER CHEVROLET PRODUCT.

TL*THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN 1500. THE CONTACT STATED THAT STRONG FUMES OF OIL AND FUEL EMITTED INTO THE VEHICLE WHICH PROGRESSED WITH NO WARNING. THE CONTACT MENTIONED THAT THE VEHICLE CONSUMED AN EXTENSIVE AMOUNT OF OIL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THE ENGINE WAS REPLACED BUT THE FAILURE RECURRED. THE CONTACT STATED THAT THE SERVICE ENGINE WARNING LAMP CONTINUED TO ILLUMINATE AND STRONG FUMES CONTINUED TO ENTER THE INTERIOR OF THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.

I BOUGHT THIS VEHICLE USED, THE DAY I GOT IT HOME IT SUDDENLY HAD NO OIL PRESSURE. CHEVY DEALERSHIP PUT A "PATCH" ON ITS BOO-BOO AND SENT ME HOME. NOW AT 140,000 MILES I ONCE AGAIN HAVE NO OIL PRESSURE. CHEVY SAYS I NEED A NEW ENGINE AND OF COURSE I'M NO LONGER UNDER WARRANTY. APPROXIMATE COST $6,700. THIS VEHICLE LEFT ME STRANDED ON THE SIDE OF THE ROAD TWICE. I HAVE FOUND HUNDREDS OF COMPLAINTS OF THE EXACT SAME ISSUE (SAME YEAR, MAKE AND MODEL) I'M HAVING AND CHEVROLET HAS YET TO ISSUE A RECALL ON THIS DEFECTIVE MOTOR. THE COMPANY RETURNED CORRESPONDENCE WITH ME AND INFORMED ME THAT THEIR "CALCULATOR" SAYS THEY CANNOT OFFER ME ANY ASSISTANCE. I NOW HAVE A 4 MONTH OLD SON AND OVER A FOOT OF SNOW EXPECTED IN MY AREA OVER THE NEXT 24 HOURS. WHAT HAPPENS IF HE IS SICK AND I HAVE NO MEANS TO GET HIM TO A DOCTOR BECAUSE OF THIS ISSUE CHEVROLET WON'T OWN UP TO? *TR

TL* THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN 1500. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 65 MPH, THE ENGINE LIGHT AND THE REDUCE ENGINE POWER MESSAGE ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE STALLED AND AS A RESULT, THE VEHICLE HAD TO BE MERGED OVER TO THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED TO AN UNKNOWN LOCATION. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

UPON START-UP, PLUME OF SMOKE FROM EXHAUST FOR 5 - 15 SECONDS. ALSO, EXCESSIVE OIL CONSUMPTION, UP TO 1.5 QUARTS PER 500 MILES. *TR

TL* THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN. THE CONTACT SATED THAT THE ENGINE WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE IT WAS DIAGNOSED THAT THE THROTTLE BODY SENSOR NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT THE REMEDY REPAIR FAILED. THE APPROXIMATE FAILURE MILEAGE WAS 95,000 AND THE CURRENT MILEAGE WAS 153,771.

WHILE THIS WAS/IS A USED VEHICLE, AND WHILE THE MILEAGE IS HIGH, THE SHEER FREQUENCY OF THE EXACT SAME COMPLAINT DICTATES THAT THIS IS A PROBLEM THAT FREQUENTLY OCCURS. FURTHER EXACERBATING THE PROBLEM IS THAT GM AND ITS DEALERS HAVE NO INCENTIVE TO FIX THE ISSUE AS A FULL ENGINE REPLACEMENT IS WHAT IS BEING OFFERED AS A SOLUTION. I WAS QUOTED BY MY DEALER THAT THE COSTS FOR THIS IS (~)$8,000.00! AS IS THE CASE WITH THE OTHERS THAT HAVE COMPLAINED ABOUT THIS: I WAS DRIVING ALONG AND THE OIL PRESSURE WENT TO ZERO. AFTER TAKING IT TO THE DEALERSHIP, THEY REPLACED A FEW COMPONENTS AND SENT ME ON MY WAY (AFTER GETTING A LARGE BILL OF COURSE). WE USE THE CAR VERY INFREQUENTLY AND AS SUCH, WITHIN A 100 MILES OF USE, I WAS BACK AT THE DEALER WITH, AGAIN, VERY LOW OIL PRESSURE. THERE RECOMMENDATION WAS TO REPLACE THE ENGINE AT $8000 OR PERFORM AN OVERHAUL AT 2000+ WITH NO GUARANTEE OR WARRANTY. THIS IS RIDICULOUS. FROM A COST STANDPOINT: THE SUBURBAN IS A $60,000+ VEHICLE, AND THE PROBLEM IS NOT FIXABLE/RESOLVABLE, OTHER THAN BY GM ASKING FOR AN ADDITIONAL $8000. FROM A SAFETY ISSUE, THESE CARS ARE HEAVY, BIG, AND CAN CAUSE MUCH DAMAGE IF THE DRIVER IS DISTRACTED BY SUCH A LARGE ENGINE PROBLEM AND/OR THE ENGINE SHUTTING DOWN DUE TO THE ENGINE BLOCK FREEZING UP AND/OR SEIZING DUE TO THE LACK OF OIL PRESSURE. NOW, AND ESPECIALLY IN LIGHT OF GMS REFUSAL TO ACKNOWLEDGE THE SAFETY RECALL ASSOCIATED WITH ITS IGNITIONS, I THINK THERE IS SUFFICIENT CAUSE FOR THE NHTSA TO TAKE A HARD LOOK INTO THIS, OPEN A FULL INVESTIGATION, AND HOPEFULLY RECTIFY THIS FOR THE HUNDRED (AND POSSIBLY THOUSANDS) OF CONSUMERS AFFECTED AND FORCE GM TO ADDRESS THESE ISSUES, BOTH WITH RESPECT TO ITS EXISTING/PAST SALES, AS WELL AS ADDRESS ITS FUTURE DESIGNS. *TR

I FIND IT INTERESTING THAT THERE ARE SO MANY COMMENTS ABOUT BURNING OIL ON THE SUBURBAN. I BOUGHT THIS CAR NEW IN 2007 WITH 0 MILES. IN 2011 WHEN HAD MY USUAL OIL CHANGED AND NOTICED THAT WITHIN 1 MONTH MY INDICATOR CAME ON THAT THE OIL WAS LOW AND TO ADD OIL. I WENT BACK TO THE LOCATION WHERE I HAD IT CHANGED AND COMPLAINED THAT THEY DIDN'T PROPERLY FILL THE OIL. THE ARGUED THAT THEY DID AND I WAS WRONG. THEY THEN PUT 2 QUARTS IN AND I WENT ON MY WAY. A MONTH LATER, AGAIN, THE SAME ISSUE. I TOOK THE CAR TO THE CHEVROLET DEALER WHERE WE PURCHASED IT AND THEY SAID THAT THE REASON THE CAR WAS BURNING OIL WAS BECAUSE I SHOULD USE A DIFFERENT WEIGHT OF OIL DURING THE HOT TEXAS SUMMER MONTHS. EVER SINCE THIS TIME MY CAR BURNS OIL NO MATTER WHAT TYPE OF OIL I PUT IN. NO MATTER WHAT TIME OF YEAR - HOT OR COLD. I KEEP EXTRA QUARTS IN THE BACK FOR EMERGENCIES. WHEN I START THE ENGINE ON MOST DAYS, BUT NOT ALL DAYS, A WHITE PUFF OF SMOKE COMES FROM THE EXHAUST. THE DEALER INSISTS THAT THERE IS NOTHING WRONG. IT'S OBVIOUS BASED ON OTHER CONSUMER COMMENTS THAT THIS IS A MANUFACTURER'S DEFECT. AT ABOUT 100K THE TIRE SENSOR WENT AND NOW AT 113K ANOTHER TIRE SENSOR IS GONE AS WELL AS THE DRIVER SIDE AUTOMATIC DOOR LOCKS. TYPICALLY WHEN I TAKE MY CAR TO THE DEALER TO BE FIXED IT RUNS AT LEAST $1000. I WAS PLANNING FOR THIS CAR TO LAST AT LEAST ANOTHER 50K MILES. WE'LL SEE... *TR

ENGINE OIL CONSUMPTION ISSUE. VEHICLE HAD BEEN TO BAYSIDE CHEVROLET IN PRINCE FREDERICK, MD SEVERAL TIMES FOR REPAIRS BUT NEVER FIXED. FINAL TIME WAS PISTONS AND RINGS REPLACED. 13 MONTHS AND 23000 MILES LATER THE ENGINE NEEDED TO BE REPLACED. *TR
