2018 Cadillac XT5 Power Train

Check engine light (power reduced steering drive safely) notice came on. Code reads P0128, coolant below thermostat regulating temperature. This is an on going issue with Cadillac. It’s definitely a defect because if you go on YouTube you will see it’s not just my vehicle even on low miles vehicles. Then you are left with no choice but to get repaired at the dealer only to be ripped off. 180 for diagnostic testing at dealer to find out this is an ongoing issue across the US

Transmission While at a red light/complete stop car will jerk out of nowhere for no reason. It also did it while driving down hill at a steady speed of 70 mph. Could have been a bad accident if a big rig or other vehicles would have been behind me.

SEVERAL MONTHS AGO, AFTER WAITING IN LINE FOR TWO MINUTES WITH THE TRANSMISSION IN D AND THE VEHICLE IDLING, I STARTED TO DRIVE FORWARD. SUDDENLY THE VEHICLE CAME TO A SHUTTERING STOP. APPARENTLY THE TRANSMISSION SHIFTED ITSELF INTO P. RECENTLY THIS HAPPENED AGAIN BUT IT OCCURRED WHEN I WAS BACKING OUT OF MY GARAGE. I AM CONCERNED THAT THIS SELF SHIFTING INTO P MAY OCCUR WHEN I AM TRAVELLING AT SOME SPEED AND RESULT IN AN ACCIDENT. I HAVE BEEN TO MY LOCAL CADILLAC DEALER BOTH TIMES AND THEY SAY THE VEHICLE IS SAFE AS IS. BUT I AM CONCERNED.

I WAS STOPPED BY A ROAD CREW. THERE WERE 3 CARS IN FRONT OF ME AND AS I WAITED FOR THEM TO LET US THROUGH ABOUT 10 CARS WERE STOPPED BEHIND ME. I WAS LISTENING TO THE RADIO WHEN I HAD THE WEIRD SENSATION THAT I WAS GOING BACKWARDS INSTEAD OF BEING STOPPED. I LOOKED AROUND, REALIZED I WAS GOING BACKWARDS AND WENT TO HIT THE BREAK BUT MY CAR HAD ALREADY HIT THE CAR BEHIND ME. THE MAN IN THE CAR BEHIND ME TOLD THE POLICE OFFICER THAT RESPONDED THAT HE DID NOT SEE BACK UP LIGHTS OR ANY INDICATOR THAT THE CAR WAS IN REVERSE. I DIDN'T TOUCH THE GEAR SHIFT. THERE IS NO REASON FOR THE CAR TO GO IN REVERSE. THE PHOTO BELOW SHOWS THE DAMAGE DONE TO THE CAR MY VEHICLE HIT.

I WAS IDLING IN LINE FOR ABOUT 5 MINUTES WAITING FOR FOOD AT MCDONALDS. TRANSMISSION WAS IN DRIVE. ONCE SERVED, I STARTED TO DRIVE AWAY BUT CAR SHUTTERED AND STOPPED ABRUPTLY. APPARENTLY TRANSMISSION WILL AUTOMATICALLY SHIFT TO PARK AFTER IDLING FOR SEVERAL MINUTES EVEN IF IT HAS STARTED TO MOVE FORWARD 1 OR 2 MPH. WHAT WOULD HAVE HAPPENED IF I WAS TRAVELING FASTER WHEN IT SHIFTED TO PARK? IS THIS FEATURE A GOVERNMENTAL REQUIREMENT? WHY?

TL* THE CONTACT OWNS A 2018 CADILLAC XT5. WHILE DRIVING APPROXIMATELY 35 MPH, "TRANSMISSION" ILLUMINATED ON THE INSTRUMENT PANEL. WHILE APPROACHING A STOP SIGN, THE VEHICLE INDEPENDENTLY SHIFTED INTO PARK WHILE STILL IN MOTION. THE CONTACT THEN SHIFTED BACK INTO DRIVE AND CONTINUED DRIVING. THE VEHICLE WAS TOWED TO THE DEALER (QUANTRELL CADILLAC, 1490 E NEW CIRCLE ROAD, LEXINGTON, KY 40509) WHERE IT WAS AWAITING DIAGNOSTIC TESTING AND REPAIRS. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 2,900.
