2015 Cadillac Escalade Power Train

Vehicle has a shake that seems to be coming from the rear and can be felt in the seats, slightly in the steering wheel while driving at highway speeds ( 70+ ) this shake or vibration come in waves but never goes away long as you are traveling at highway speeds . It goes from an annoying shake to a bad shake and from a bad shake to annoying shake if that makes sense . I’ve spoken with different mechanics including the GM dealer and no one seems to have a fix just recommendation of expense part replacements that hasn’t worked for other Escalade owner with the same issue . I have experienced hard shifting from park to reverse and from 1st gear to 2nd but a temp sensor replacement seemed to have resolved the harsh shifting some what. It’s not as bad but still feel a gear thud when shifting after a cold start but not so much after it’s been driven for awhile. My main concern is the shaking . It’s an embarrassing ride with passengers to the point I avoid driving it on long trips For fear that my Escalade will break down completely leaving myself and family stranded. I’m not looking for free handout repairs I just want to be pointed in the right direction of a sure fire resolution so I can get it repaired and start enjoying my vehicle .

Radical shifting shuttring unknown what gear to select into

The contact owns a 2015 Cadillac Escalade. The contact stated while driving at an undisclosed speed with the vehicle in 4WD, he heard an abnormal grinding sound. The contact shifted to AWD and heard the grinding sound as well. The vehicle was taken to an unknown dealer and the contact was informed that the front differential needed to be replaced. The vehicle was repaired however, the failure persisted. The vehicle was then taken to an independent mechanic and the contact was informed that the front differential was defective and needed to be replaced again. The manufacturer was made aware of the failure and agreed to pay a portion of the repair cost. The failure mileage was 62,830.

TRANSMISSION IS NOT SHIFTING PROPERLY. JUMPS BETWEEN LOWER GEARS. FOLLOWED THE FIX GM RECOMMENDED WHICH CHANGED THE TRANSMISSION OIL TO ONE OF A DIFFERENT TYPE AND VISCOSITY. WORKED FOR AWHILE BUT SHIFTING ISSUES HAVE COME BACK. A BIT DISCONCERTING WHEN IT DOES IT. STARTLES AND DISTRACTS THE DRIVER AND CAN CAUSE POTENTIAL OVER-COMPENSATION AND BRAKING. NOTICED MORE AS WINTER IS TRANSITIONING TO SPRING.

MY 2015 CADILLAC ESCALADE HAS SPENT MORE THAN 2 MONTHS IN THE CADDILAC DEALERSHIP TO TRY AND RESOLVE ISSUES SURROUNDING THE TRANSMISSION. THIS CAR OVER TIME HAS SHOWN SIGNS OF SHUDDERING, MIS-SHIFTING, JOLTING AND DIVING. MOST RECENTLY THE CAR SHIFTS FROM 2ND TO 1ST BELOW 20MPH CAUSING THE REAR WHEELS TO SPIN AND MAKING THE CAR UNSAFELY JOLT FORWARD. NOTHING SEEMS TO RESOLVE THIS ISSUE AND THE CAR IS UNSAFE FOR ME AND MY FAMILY. I HAVE TRIED TO WORK WITH THE DEALERSHIP OVER THE LAST 1.5 (4 VISITS) YEARS AND EVERY TIME THERE IS A NEW FLUID OR A NEW REPROGRAM THAT GM MAKES THEM TRY. MOST RECENTLY I OPENED A CASE WITH GM: 9-576-707-5930 BECAUSE THE DEALERSHIP HAS NO OTHER OPTIONS ON FIXING THE CAR.

TRANSMISSION/ DRIVE TRAIN HAS DISTINCT CLUNKING NOISE WHEN EITHER ACCELERATING AND OR DECELERATING. THERE IS A DISTINCT DELAY SURGE WHEN ACCELERATING FROM STOP AND OR SLOWING DOWN AT SLOW SPEEDS AND OR FROM SLOPED STREETS. THE CLUNKING AND JERKING IS NOT SAFE AND CONDUCIVE TO NORMAL DRIVING AND OPERATING.PARAMETERS. THE DELAYED SURGING AND JERKING CREATES AN ABNORMAL ACCELERATION BOTH IN THE VEHICLE AND FOR SURROUNDING TRAFFIC WHEN STARTING FROM A RED LIGHT OR STOP SIGN. GM DEALERS/ REPAIR FACILITY TECHS ARE AWARE OF THIS SAFTETY/DESIGN DEFECT YET GM HAS YET TO ADMIT/ AND OR ACKNOWLEDGE AND OR PROVIDE A FIX FOR THIS SAFETY PROBLEM. THIS VEHICLE HAS BEEN IN FOR REPAIR OF THIS PROBLEM MANY NUMEROUS TIMES BUT GM DOES NOT OR WILL NOT FIX THIS SAFETY DEFECT WITHOUT FIRST ACKNOWLEDGING THIS. PROBLEM! THIS HAS BEEN AN ONGOING PROBLEM SINCE THE VEHICLE WAS NEAR BRAND NEW. ORIGINAL TRANSMISSION WAS REPLACED AND VEHICLE HAS BEEN IN FOR THIS PROBLEM STILL, AND TO THIS CURRENT MILEAGE, OVER 65.000 MILES THIS SAFETY PROBLEM IS WORSENING!

CAR, AT TIMES, FAILS TO ENGAGE INTO DRIVE, WHEN AT A STOP. ALSO, WHILE DRIVING, CAR, AT TIMES, WILL NOT ADVANCE TO THE NEXT GEAR UPON ACCELERATION. ALSO, WHILE DRIVING AT CONSTANT SPEED, CAR SHUDDERS AND CANNOT MAINTAIN THE PROPER GEAR.

VEHICLE VIBRATES EXCESSIVELY WHEN DRIVING. AT FIRST I THOUGHT IT WAS DUE TO ROAD CONDITIONS BUT THEN REALIZED THE VIBRATION RESIGNATES FROM MY VEHICLE DRIVETRAIN. TOOK IT TO DEALERSHIP AND THEY INFORMED ME IT'S MY TORQUE CONVERTER. APPARENTLY THERE ARE MANY COMPLAINTS WITH THIS ISSUE WITH 6 SPEED TRANSMISSION OPERATED VEHICLES FROM GM. STILL WAITING ON RECAL FROM GM TO BE PUBLISHED.

MY CONDENSER AN MY WHOLE AIR CONDITIONING SYSTEM WENT OUT. I HAD TO GET IT COMPLETELY REDONE.
