2016 GMC CANYON Power Train Problems

At random the power steering and traction control turn off making it difficult to drive.. This happens randomly and has become unable to steer. Once the vehicle is turned off for a period of time you can start it up and the steering returns. The issue was reported in the 2015 models. That recall needs to extend into the 2016 models since most of the parts were most likely manufactured tot eh same specs as the 2015. The vehicle was diagnosed by an independent repair shop. The dealership wanted $200 for just the diagnostics. Every time this happens it becomes very difficult to drive and is a safety issue. The issue first appeared 2 months ago and after the restart stopped. Then all of a sudden it seems to occur daily.

Transmission has been shuddering since 15,000 miles till now. Dealerships says it's normal on these transmissions, 6 fluid and filter changes and now at 72,000 miles the transmission is failing just outside of warranty. They scammed me and kept my transmission barely alive until warranty ran out and now they want 8k-10k for a replacement. They knew. Dash goes crazy from the touch screen to the digital information screen in the speedometer. They say it's normal and happens on all the units. But it's distracting and has been messing up since bought the truck new. Again they just kept saying it was nothing they can do. Now they say it needs to be replaced after my warranty has run out. DEF system is failing conveniently after the warranty has run out. It's dangerous because they programmed the truck to go into limp mode when anything emissions related fails stranding me anywhere at anytime. Emission failures like sensors should not restrict travel. This is a major issue with the diesels in these trucks and they need to be forced to remove anything that's not dangerous to the health of the engine or drive train from the software or hardware from being able to restrict travel. In every situation I've been restricted to limp mode by dirty particulate sensors, but the code that pops and puts my truck in limp mode says that the NOX sensor is bad. This is false and is just a way for GM to get service at their dealers. Then they charge customers a fortune to replace parts that don't need to be replaced when you can just remove and clean the four particulate sensors and the restrictions will clear themselves shortly after. EMISSIONS RELATED ISSUES SHOULD NOT RESTRICT TRAVEL BY ANY MEANS! It is dangerous to be stranded on a trip because your emission sensors may be malfunctioning.

Complete loss of power steering and traction control while driving. Very difficult to make turns. Would have to pull off the road and restart vehicle to fix problem. I have not taken it to a service center. It has not been inspected. Warning lights for loss of stabilitrak do come on.

I have not been in an incident yet, but when I slow down coming off the highway and try to come back up to traffic speed the the transmission bucks or shutters. Also when starting from a red light or stop sign the truck bucks or shutters very notable in 3-4-5th gear. I watched the tachometer and it shutters most of my drive. In all fairness, I have not brought it to the dealership yet. I see other people are having this problem with the Canyons and Colorado also. Please advise!

Driving and the Stabilitrak warning comes on as well as the Power steering warning. later after the vehicle is turned off it will not restart (no crank, no Start) and there is no communication with the ECM until it has had the battery disconnected for an extended period. This is very dangerous losing power steering and stabilitrak while driving is going to cause an accident. I would like to see a recall on the 2016 like there is on the 2015 with this same issue. I have not had the issue repaired yet. waiting to get it into a shop who tells me they will likely need to replace the Rack and Pinion on this truck to correct the issue.

Ignition key randomly will not release from switch. The key is stuck in the ignition in the accessory position which in turn kills the battery. As far as I can tell (and I have read about and experienced this problem for many months) the root cause is the gear shift assembly or Part # 23397472. It is not reliably returning the confirmation, to the solenoid lock on the ignition switch, that the transmission is in PARK reliably. For the first time last w/e my dealer admitted this is a problem and that replacing 23397472 usually resolves the issue. I need GM to take responsibility and activate a recall

Key is not pulling out of ignition after truck has been put in park. Mechanic has replaced the shifter twice, and yet the problem is more pronounced. The Dealership (Anthony GMC) has now stated there is no problem, and yet the key wont come out for them either.

•Water coolant valve, and torque converter. •my Truck temp gage will fluctuate towards red line and back to normal. Torque converter caused my vehicle to shake, vibrate, slow accelerating, made it seem vehicle will shut off on highway or in heavy traffic. •I went to several mechanics, including the dealerships and they fixed my water coolant valve but issue persisted, the dealerships said my truck was running fine until I had requested to ride along with mechanic, that's when he guessed it would be torque converter. •has not been inspected, just test drove and replaced by mechanic •no lights indicated on dash board and I felt the shake and vibration around 08/01/2021 and reported to dealership. The water temp gage was reported back in Nov 2018 but the problem still persist.

Have had truck in shop several times, currently in the shop and has been there for almost 3 weeks nobody seems to know what the problem is. Vehicle losses power and goes into a limp mode. Temperature gauge keeps failing, exhaust break does not work, ac cuts out often and does not work often, keeps trying to clean exhaust filter over and over again and again.

VEHICLE DOES NOT RESPOND TO ACCELERATION COMMAND WHILE ENTERING A HIGHWAY OR DURING HIGHWAY DRIVING, INCREASING THE RISK OF COLLATION WITH OTHER VEHICLES DUE TO TRANSMISSION FAILURE, SUSPECT THE TORQUE CONVERTER NOT WORKING PROPERLY. THIS IS A MAJOR AND WELL KNOWN ISSUE, GM CONTINUES TO IGNORE AND I DO NOT WANT TO BECOME THE NEXT STATISTIC DEAD IN US HIGHWAYS. THE VEHICLE IS MOVING, DURING A RED TRIANGLE YIELD SIGN ENTERING THE HIGHWAY, THE VEHICLE WILL NOT RESPOND TO ACCELERATION COMMAND CAUSING A BOTTLE NECK OF TRAFFIC BEHIND ME AND HIGH RISK OF BEING REAR ENDED. THIS IS A SERIOUS DEFECT AFFECTING THE TRANSMISSION, IT NEEDS TO BE INVESTIGATED AND RESOLVED AS SOON AS POSSIBLE.

VEHICLE FREQUENTLY SHUTS OFF DURING BRAKING OR WHILE STOPPED AND MUST BE RESTARTED BEFORE THE VEHICLE CAN OPERATE AGAIN. VEHICLE EXPERIENCES VIOLENT GEAR CHANGES AND SIGNIFICANT LAGGING DURING PERIODS OF MODERATE ACCELERATION AT LOW SPEEDS. GEAR CHANGES RESULT IN EITHER SEVERE UNRESPONSIVENESS AND A GENERAL LACK OF ACCELERATION OR AN AGGRESSIVE GEAR CHANGE THAT JERKS THE VEHICLE AND SPINS THE TIRES.

Mileage: 49,000

TRANSMISSION CONSISTENTLY SHUDDERS WHEN ACCELERATING IN ALL DRIVING CONDITIONS AND SPEEDS, AND SOMETIMES GOES TO HIGHER RPMS WHEN ENGINE IS WARM AND RESTARTED. DEALER SAID THIS WAS NORMAL WHEN RECENTLY BROUGHT IN. IT WAS NOT SHOWING ANY CODES. DEALER SAID NOT TO KEEP 4X4 IN AUTO MODE. LESS THAN A WEEK AFTER RECEIVING TRUCK BACK FROM DEALER, A 4 WHEEL DRIVE WARNING MESSAGE WAS DISPLAYED AND THE CAR WOULD NOT GO INTO 4 WHEEL DRIVE OR AUTO. MESSAGE AND PROBLEM COMES AND GOES. SHUDDERING SHOULD NOT OCCUR AND KEEPING IN AUTO MORE DURING RAIN AND COLD WEATHER IS A SAFETY PRECAUTION THAT SHOULD NOT BE AN ISSUE.

THE THROTTLE AND TRANSMISSION FEEL AS THOUGH THEY WERE SEPARATELY DEVELOPED FOR TWO DIFFERENT VEHICLES AND JUST RANDOMLY MATCHED IN THE TRUCK. THE ACCELERATOR IS VERY NON-LINEAR AND UNRESPONSIVE. THEN THE TRANSMISSION IS CONSTANTLY IN THE WRONG GEAR. THIS TRUCK IS A NIGHTMARE TO DRIVE IN TRAFFIC OR ON WINDY HILLY ROADS. YOU HAVE TO CONSTANTLY GUESS WHERE YOUR FOOT SHOULD BE TO GET ANY KIND OF STABILITY OR ACCELERATION FROM THE TRUCK. IF YOU ARE TRYING TO PULL OUT IN TRAFFIC YOU BETTER BE PREPARED TO HAVE A LOT OF ROOM BECAUSE IT MIGHT JUST SHAKE AND SHUTTER BEFORE FINDING A GEAR AND ACTUALLY ACCELERATING. THIS IS DANGEROUS AND I FIND IT ODD THAT THERE HAVENT BEEN COLLISIONS ATTRIBUTABLE TO THIS. IF ANYONE FROM GM IS READING THIS, KNOW THIS WILL BE THE LAST GM PRODUCT I EVER BUY. EITHER YOU DONT KNOW HOW TO ENGINEER A VEHICLE, OR YOU SIMPLY JUST DONT CARE ABOUT YOUR CUSTOMERS. IM GUESSING THE LATTER.

IGNITION WILL NOT FULLY TURN OFF AND RELEASE KEY WHEN TRUCK IS PLACED IN PARK. I'M ADDITION IGNITION AND KEY BECOME VERY HOT TO THE TOUCH AFTER DRIVING FOR OVER 20 MINUTES (TEMP OUTSIDE IS COOL 50-60). TRUCK WILL EVENTUALLY TURN OFF AND RELEASE THE KEY AFTER RESTARTING AND SHIFTING THROUGH ALL GEARS MULTIPLE TIMES (TURNING OFF, BACK ON, SHIFTING, ETC.). ALREADY ATTEMPTED CLEANING KEYS (BOTH SETS) WITH NO CHANGE IN BEHAVIOR.

TOUCH SCREEN AND IN DASH DIGITAL SPEEDOMETER RANDOMLY CHANGES ON ITS ON, THE TOUCH SCREEN WILL NOT RESPOND AND CHANGE RADIO STATIONS, VOLUME, CONTACT ON STAR, TRY TO USE PROJECTION OPTION, MOVE THE MAP ON GPS, AND CHANGE THE DIGITAL SPEEDOMETER FROM SPEED LIMIT TO RADIO STATIONS. ON MULTIPLE OCCASIONS WHILE DRIVING AT NIGHT THE ENTIRE DASH, RADIO, GAUGES LIGHTS EVERYTHING WENT BLACK RANDOMLY AS IF THE TRUCK WAS NOT TURNED ON BUT THE TRUCK CONTINUED TO DRIVE NORMAL AND AFTER WHAT LOOKS LIKE A RESET MAYBE 20-30 SECONDS EVERYTHING REBOOTS AS IF YOU JUST STARTED THE TRUCK. THEN IT'S BACK TO RANDOM BERSERK OUTBURSTS BY THE TOUCH SCREEN. TRANSMISSION STARTED GETTING JERKY BETWEEN GEARS AT 15K MILES AND HAS ONLY GOTTEN WORSE AT 35K MILES. ENTIRE VEHICLE SHAKES BETWEEN GEARS FRONT TO REAR AND BACK. THROUGH ALL GEARS. ALSO SOME STRONG HARD HITTING SHIFTS. DEALERSHIP HAS HAD VEHICLE 2 TIMES FOR BOTH ISSUES AND SEE NOTHING WRONG. THEY ARE CLEARLY LYING. GM WILL ALSO NOT HELP AND HAVE BEEN CONTACTED DIRECTLY.

VEHICLE HAS FREQUENT SLOW ACCELERATION WHEN ENTERING HIGHWAYS. I HAVE TO STEP ON THE ACCELERATOR HARD TO HAVE THE ENGINE PICK-UP SPEED, WHICH LEADS TO THE ENGINE OVER ACCELERATING. WHEN I SLOW DOWN ON SHARP ROAD TURNS AND ACCELERATE TO PICKUP SPEED THE TRANSMISSION SHIFTING THE GEAR HARD (MAKING A THUMP SOUND). HAVE GONE TO DEALER AT MERCED GMC AND TURLOCK CHEVROLET. BOTH STATE CAR IS RUNNING THE WAY GMC MANUFACTURED IT.

1) <POWERTRAIN> I HAVE 40K ON MY CANYON AND AM EXPERIENCING ACCELERATION ISSUES 0-40MPH 1-3RD SHIFT POINTS (AUTOMATIC TRANSMISSION). THE TRANSMISSION ACTS LIKE IT CANNOT DECIDE TO EITHER SAY IN 2ND OR SHIFT TO 3RD AND THERE'S A LAG OR SURGING AFFECT WHEN THIS HAPPENS. I HAD THE TRANSMISSION FLUID AND TRANSFER CASE FLUIDS CHANGED AR THE GM DEALERSHIP. PROBLEM STILL PERSISTS. 2) <OTHER> KEY GETS STUCK IN THE IGNITION. WHEN PLACING THE TRUCK IN PARK THERE'S AN INTERNAL RELAY/SWITCH WITHIN THE SHIFTER THAT IS SUPPOSED TO ACTIVATE A RELAY/UNLOCK SIGNAL TO THE KEY TUMBLER IN THE STEERING COLUMN. THIS DOESN'T ALWAYS HAPPEN AND THE KEY WON'T TURN TO THE OFF POSITION TO ALLOW IT TO BE RELEASED. I HAVE TO TURN THE KEY TO THE ACC POSITION PUT THE TRUCK IN DRIVE THEN BACK INTO PARK TO GET THE RELAY/SWITCH TO DIS-ENGAGE THE KEY POSITION FROM BEING LOCKED IN ACC.

MY TRUCK WILL I ENGAGE INTO FOUR WHEEL DRIVE ALL BY ITSELF .ITS BEEN TO THE THE DEALERSHIP NINE TIMES AND I'M FEELING VERY UNCOMFORTABLE DRIVING THIS VEHICLE.IF THIS VEHICLE GOES INTO FOUR WHEEL DRIVE WHILE I'M ON A MAJOR HIGHWAY IT COULD BE UNSAFE TO MY LIFE AND OTHERS THAT ARE DRIVING WITH ME.BUT THE DEALERSHIP IS NOT TAKING THIS PROBLEM VERY SERIOUSLY I THINK.THIS PROBLEM IS THIS GOING ON. REFERENCE NUMBER 11012598

TRANSMISSION HUNTS FOR GEAR WHEN TRYING TO ACCELERATE 25-40 MPH WHEN TRANSMISSION TEMP IS 120 DEGREES AND HIGHER IN SLOW AND GO DRIVING. LEADS TO DANGEROUS SITUATION BECAUSE ACCELERATOR PEDAL MUST BE 'STOMPED' ON TO GET TRANSMISSION TO DOWNSHIFT. ESPECIALLY DANGEROUS ON WET ROADS WHEN REAR OF TRUCK CAN SWERVE WHEN ACCELERATING AND IN SLOW AND GO TRAFFIC HAVING TO PUSH HARD ON ACCELERATOR TO GO WHEN MANY CARS AROUND. GM KNOWS OF THE PROBLEM AND PUBLISHES PAPER STATING EXACTLY THE SYMPTOMS AND AND TELL DEALERS NOT TO TAKE FURTHER ACTION OTHER THAN MAKING SOFTWARE UP TO DATE WHICH SOLVES NOTHING. NOT ALL GM TRUCKS AND EVEN CARS OF THIS YEAR ARE AFFECTED BUT YEARS BEFORE AND AFTER FOR DECADES HAVE THIS SAME ISSUE AS FOUND ON INTERNET FORUMS. CHANGING TO DIFFERENT TRANSMISSION FLUIDS AND EVEN CHANGING TORQUE CONVERTORS HAS BEEN DONE IN THE PAST BUT FOR 2015/2016 NO REMEDY IS OFFERED. THIS HAS BEEN GOING ON 1.5 YEARS SINCE NEW AND GETTING WORSE. BECAUSE OF LACK OF OUT OF SERVICE DAYS I DON'T THINK LEMON LAW APPLIES

SLOW AND GO DRIVING 20-40MPH AFTER COASTING AND TRYING TO ACCELERATE AGAIN THE TRANSMISSION BUCKS HESITATES TRYING TO FIND A LOWER GEAR. IT CAN'T DECIDE WHICH GEAR TO GO INTO AND JUST SPUTTERS AND CHUGS UNTIL I PUSH THE ACCELERATOR 1/2 WAY DOWN OR MORE THE FINDS ITS GEAR AND ROCKETS OFF. THIS TYPE OF DRIVING NOT SAFE AT ALL. THIS HAPPENS ALL THE TIME SINCE PRACTICALLY NEW. GM CLAIMS ITS NORMAL. BULLETINS TO NOT FIX ANYTHING EXCEPT UPDATE THE SOFTWARE. THAT DOESN'T ACCOMPLISH ANYTHING. THIS IS A KNOWN GM ISSUE WITH COLORADOS AND CANYONS AND GM CHANGED TRANSMISSIONS FOLLOWING YEARS AND NO SUPPORT FOR 2015-16

UNPREDICTABLE ACCELERATION LIMITS DRIVERS ABILITY TO SAFELY MERGE WITH TRAFFIC OR CHANGE LANES. VEHICLE CAN TAKE UP TO 3 SECONDS TO BEGIN ACCELERATION AFTER GAS PEDAL IS PRESSED AND THEN CAN SURGE UNPREDICTABLY. I HAVE SEEN THIS ISSUE REPORTED IN GMC FORUMS BY OTHERS. GMC SAYS THERE IS NOTHING WRONG.

TRANSMISSION SEEMS TO BE CONFUSED. IT WILL HESITATE DURING ACCELERATION AND SHIFT UP AND DOWN WHILE COASTING. MOST SLUGGISH SHIFTING OCCURS DURING LOWER SPEEDS. IT ALSO HAS A HABIT OF DOWNSHIFT TO LOW GEAR WHILE COASTING DOWNHILL. ALWAYS SEEMS TO BE FIGHTING WITH ITSELF!

WHEN ATTEMPTING TO TURN LEFT ONTO A HIGHWAY FROM A STOP SIGN, THE TRANSMISSION FAILED TO ENGAGE, WITH A 2-SECOND DELAY BEFORE ENGAGING AND ACCELERATING INTO THE TURN. AS A RESULT OF THE DELAY, I WAS NEARLY HIT BY ONCOMING TRAFFIC. THIS VEHICLE MODEL, 2016 GMC CANYON, HAS A HISTORY OF NOT BEING IN THE PROPER GEAR WHEN STOPPED OR MOVING AT SPEEDS BELOW 3-5 MPH. THIS ISSUE HAS HAPPENED TO ME OVER 100 TIMES IN THE FIRST 6 MONTHS OF OWNERSHIP, BUT THIS WAS THE FIRST TIME I NEARLY HAD A DANGEROUS COLLISION. GMC SHOULD CORRECT THIS PROBLEM WITH THE TRANSMISSION NOT BEING IN THE PROPER GEAR FOR BEING STOPPED OR FOR EXTREMELY LOW SPEEDS. *TR

NOTICED A FEW DAYS AFTER I BOUGHT THE TRUCK IT SEEMS THE TRANSMISSION NEVER KNOWS WHAT GEAR TO BE IN. YOU CAN TAKE OFF FINE BUT WHEN YOU TRY TO ADD A LITTLE SPEED, DOES NOTHING UNTIL A FEW MORE INCHES OF PEDAL IS APPLIED THEN IT ACCELERATES WAY TO FAST, ALMOST HIT THE CAR IN FRONT SEVERAL TIMES. ALSO, COMING OUT OF U-TURN OR FREEWAY UNDERPASS, SEEMS TO BE STUCK IN 6TH GEAR, HAVE TO DANG NEAR FLOOR IT TO GET IT TO ACCELERATE , ALL THE WHILE FOLKS ARE TRYING NOT TO HIT ME FROM BEHIND SINCE I AM NOT MOVING VERY WELL. FREEWAY DRIVING, SAME ISSUES, SAY YOU ARE AT 60MPH AND TRAFFIC CLEARS AND YOU TRY TO ADD A LITTLE PEDAL TO GET TO 65-70, I HAVE TO PUSH DOWN 2-3 INCHES BEFORE ANYTHING HAPPENS. SAME WHEN DRIVING 30 THEN TRYING TO GO TO 45, SHUDDERS AND STUMBLES LIKE A MANUAL TRANSMISSION VEHICLE WOULD IN 5TH GEAR @ 30MPH. YOU HAVE TO REALLY STAY ON THE GAS AND DRIVE HARD TO FOR IT TO DO ANY BETTER. I TOOK BACK TO THE DEALER UNDER WARRANTY AND WAS TOLD THIS IS NORMAL ACCORDING TO GMC TECH SUPPORT. NOT. I HAVE BEEN DRIVING 45 YEARS, MANY DIFFERENT CARS, AND THIS IS IN NO WAY NORMAL. IT IS NOT ONLY AGGRAVATING BUT QUITE DANGEROUS. FROM WHAT I HAVE SEEN ONLINE, THIS IS A VERY COMMON COMPLAINT. SHOULD TAKE NO MORE THAN SOME RE-PROGRAMMING OF THE SHIFT POINTS AND THROTTLE POSITION SENSOR. *TR

VEHICLE BOGS AND MISFIRES AT RPMS BELOW 2000 CAUSING A SIGNIFICANT SAFETY PROBLEM. VEHICLE REFUSES TO ACCELERATE AT LOW RPM UNLESS IT DOWNSHIFTS. RESEARCH ON THE INTERNET FINDS MULTIPLE COMPLAINTS FOR THE SAME ISSUE. I TEST DROVE A 2017 GMC CANYON AND IT EXHIBITED THE SAME ISSUES.

TRANSMISSION HESITATES DRAMATICALLY BETWEEN SOME SHIFTS..LONG PERIODS WHERE TRANSMISSION SEEMS TO BE IN NEUTRAL. TYPICALLY HAPPENS IN LOWER GEARS, SUCH AS BETWEEN 2 AND 3 GEARS. PRESSING ACCELERATOR THEM CAUSES A CLUNK INTO GEAR. ALSO, ON HIGHER SPEEDS, DOWNSHIFTS ARE SLOW TO OCCUR BUT THEN SEVERAL GEARS SEEM TO BE SKIPPED WHEN THE DOWNSHIFT FINALLY OCCURS, WITH SCREAMING ENGINE RPMS. THIS IS A 4 CYLINDER MODEL WITH 6 SPEED AUTOMATIC TRANS.

I BOUGHT A BRAND NEW 2016 CANYON, TEST DRIVE WENT WELL, ALTHOUGH I ADMIT IT PROBABLY WASN'T LONG ENOUGH. PURCHASED ON SUNDAY, AND DURING THE NEXT WEEK DRIVING I BEGAN NOTICING THE TRANSMISSION WAS NOT SHIFTING AT THE PROPER TIMES. LIKE MOST PEOPLE ON HERE, THE TRANSMISSION APPEARS TO BE VERY CONFUSED , ESPECIALLY WHEN DECELERATING INTO THE 20-35 MPG RANGE AND ATTEMPTING TO RE-ACCELERATE BACK UP. IT WILL MISFIRE OR BE VERY UNRESPONSIVE, AND THEN CLUNK AND JERK YOU FORWARD ONCE IT DECIDES TO CHANGE GEARS. IT ALSO DOES SOMETHING THAT I THINK IS EVEN MORE DANGEROUS WHEN YOU ARE GOING AROUND 30-40 MPG AND THEN SIMPLY LET OFF THE ACCELERATOR. IN THIS INSTANCE, I FEEL LIKE IT DOWN SHIFTS INSTANTLY AND IT FEELS LIKE THE TRUCK IS BEING PULLED BACK (INSTEAD OF SIMPLY COASTING LIKE I WOULD WANT), AND THEN AT SOME POINT IT "RELEASES" FROM THIS AND THE TRUCK ACTUALLY STOPS DECELERATING AND SPEEDS UP A BIT, EVEN THOUGH THE GAS HAD BEEN RELEASED MANY SECONDS AGO. THIS IS PARTICULARLY DANGEROUS IN STOP AND GO CITY TRAFFIC. I THINK THE OVERARCHING PROBLEM HERE IS THE SHIFT POINTS THAT THE ECM HAS DETERMINED (OR BEEN PROGRAMMED WITH). YOU CAN TELL THIS WHEN ACCELERATING FROM A STOP, MY TRUCK GETS TO THIRD GEAR BY 15 MILES PER HOUR AND NEVER GOES ABOVE 2K RPM'S??? I ADMIT I AM A BIT LIGHT-FOOTED ON DRIVING, WHICH COMPOUNDS THE PROBLEM BECAUSE I EVENTUALLY AM GIVING A SMALL AMOUNT OF ACCELERATION TO A TRUCK IN 4TH GEAR ONLY GOING 20 MPH, WHICH SUCK. I HAVE ALSO READ THIS WAS A COMMON PROBLEM ON 15 CANYON (OBVIOUSLY READ AFTER PURCHASE), AND GMC EVENTUALLY CAME OUT WITH A FEW FIXES, INCLUDING ECM PATCH UPDATES OR LOWER VALVE REPLACEMENT. I IMAGINE THAT MANY OF THE 2016'S WERE ALREADY OFF THE LINE BY THE TIME THESE '15 FIXES CAME OUT (IN APRIL 15 I BELIEVE), BUT THE DEALERSHIPS HAVE NOT RECEIVED ANY OF THESE FOR THE 2016.

THE TRANSMISSION DOES NOT DOWNSHIFT FROM A HIGH GEAR (5 OR 6) TO A LOWER GEAR WHEN SLOWING DOWN FROM 45 MPH TO 20 MPH (OR LOWER). WHEN THE ACCELERATOR IS DEPRESSED TO ACCELERATE THE ENGINE BUCKS, VIBRATES, AND DOES NOT ACCELERATE. THE ENGINE RPM DROPS TO 1,000 RPM OR LOWER. IF THE ACCELERATOR IS QUICKLY FLOORED THE TRANSMISSION DOWNSHIFTS SEVERAL GEARS LOWER AND JERKS FORWARD. THIS CONDITION HAPPENS PRIMARILY ON SECONDARY ROADS WHILE DRIVING ALONG THE ROAD AND WHEN PULLING FROM ONE ROAD INTO TRAFFIC ON ANOTHER ROAD. THE SITUATION WHEN PULLING INTO TRAFFIC IS DANGEROUS BECAUSE THE TRUCK DOES NOT ACCELERATE AS IT SHOULD.
