2017 Cadillac XT5 Steering Problems

While driving my vehicle, alert popped up on my dash stating "Steering Assist is Reduced Drive with Care" futhermore after that my Check Engine Light Turned on and my Engine Heater Stayed cold and would not warm up. Vehicle has been inspected by the Cadillac Dealer and they stated it is all due to the Sensor. However Sensor is on backorder and has taken them 3 week to get the part. They stated it is safe to drive even though all those alerts came up, since he said it appears to be stuck open, however they stated if it gets stuck in a closed state then the engine could overhead which would require having the vehicle towed in. They offer a "limited" warranty on this however since I just was past the warranty period they state you have to pay the full price. Warranty is for 85,000 miles and I am barely above it at 87675.

“Steering assistance is reduced Drive with care” message while driving. Engine light appeared

Our XT5 began getting 'Steering Assist Reduced' message about a year ago. It comes and goes , coming more often now. The problem is the thermostat and is a very common issue with numerous complaints here and on Cadillac forums (below). The problem is, when this issue occurs the AC stops working, and when that happens you have no windshield defrost, and that is a safety problem. Cadillac has TSB's describing this issue but refuses to cover it goodwill as we are slightly out of warranty. The repair is extensive, requiring 4.5 of time.

Message Displayed on 2017 Cadillac XT-5 "Steering Assist is Reduced - Drive With Care". No check engine light, and no apparent loss of steering. Noted that Temperature Gauge and Air Conditioning ceased to work. Suspiciously, a 2019 Cadillac XT-5 that I also own, the identical displayed message came on, with identical same mechanical issue, and just learned that an acquaintance with a newer Chevy Blazer just experienced the identical issue also. All vehicles are equipped with OnStar. Coincidence, OR any possibility that GM or OnStar computers have been hacked into, as OnStar has ability to control various functions of vehicles. To correct the issue (possibly only temporary) was to remove the negative battery cable for a short time, and reattach.

Message Powersteering Assist is reduced. This could cause steering problems and a potential collision. Cause is due to failure of thermostat design and insta llation. Believe an investigation is possibly warranted. GM issued a service bulletin making dealers aware of the faulty design in May 2017. But consumers were not advised of the danger.

The power assist steering goes out and you have to manually try to steer the car the part that has to be replaced is the power assist steering module which is located in the steering assembly I have found this to be a problem with Cadillac XT5 models from 2017 through 2019 also in a Chevrolet SUV MODEL of the same years an internal memo was sent out but not notified owners

THE 2017 CADILLAC XT5 HAS A DEFECTIVE THERMOSTAT, WHICH SENDS A FALSE SIGNAL THAT THE ENGINE IS OVERHEATING. THEREFORE, YOU GET A "STEERING ASSIST IS REDUCED DRIVE WITH CARE", WHICH YOUR STEERING TO BE HARD AND NOT AS EFFECTIVE AS IT SHOULD BE. GMC IS AWARE OF THE PROBLEM, BUT FAILED TO REMEDY IT, BUT ISSUED A BULLETIN #17-NA-158 IN MAY OF 2017. THIS PROBLEM IS SO WIDESPREAD THAT THE PART TO FIX THE PROBLEM IS ON "BACK ORDER" EVERYWHERE.

The contact owns a 2017 Cadillac XT5. The contact stated that while her husband was driving at approximately 50 MPH, the vehicle lost power steering functionality. The contact stated that the power steering assist message was displayed. The vehicle was taken to the local dealer where it was diagnosed and determined that the power steering assist had failed. The contact was informed that the part was on backorder. The vehicle was not diagnosed or repaired. The manufacturer was contacted. The failure mileage was approximately 78,146.

Check engine code p0128. driver assistance, air conditioning and steering affect.

To recall department, I purchased the above car in Jan 2021 since that time I had to take this car in for repairs 3 times concerning steering brake problem and reducing speed and also the thermostat problem. In reviewing this the consumer reports I found out that this was one of the worst years of making the xt5 and a recall was done for 2017 but for the cars that was manufactory in 2016. if a car get on the dealers floor in 2017 most likely it was manufactured in 2016. so I want to know why my car hasn't been notify for a recall and I'm having to take this car to the shop on three or four occasions for the same problem. I would like to somebody to look into this situation and reimburse me for my out of pocket expensive. This should be a manufactory problem and GM should be doing the repairs for free. Please feel free to contact me for any additional questions or concerns. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

STABILIZE WARNING KEEPS COMING ON AND SAYS TO SET PARKING BREAK AS WELL. READING ABOUT THIS, IT IS A VERY COMMON WARNING THAT CAUSES THE STABILITY SENSORS TO FAIL AND INCREASE LIKELIHOOD OF A CRASH FOR SOMETHING THAT IS SUPPOSED TO BE A SAFTEY FEATURE ON THIS VEHICLE. THIS CREATES AN UNNECESSARY SAFTEY HAZARD THAT CADILLAC WILL NOT ADMIT TO OR FIX. THIS SEEMS TO ONLY HAPPEN WHEN SITTING STILL AT A STOP LIGHT OR STOP SIGN.

PURCHASED NEW XT5 IN FEB 2017, CURRENTLY 8300 MILES. AFTER STARTING MY VEHICLE AND SHIFTING INTO REVERSE, THE TRANSMISSION MAKES AN LOUD BANG AND LURCHES BACKWARD. THE FIRST TIME IT OCCUR IN MAY 2017 IT CAUGHT ME OFF-GUARD AND THE VEHICLE MOVED BACKWARDS ABOUT 3 FEET. SINCE THEN THIS HAS OCCURRED ABOUT 12 TIMES AND HAVE RETURNED THE VEHICLE TO THE DEALER FOR SERVICE, NO ISSUES FOUND OR REPEATED. RETURNED THE VEHICLE AGAIN 8/28/17 FOR SERVICE FOR THE SAME REASON. ALSO THE SUSPENSION IS VERY ROUGH, WHEELS FELL LIKE THEY ARE CONSTANTLY SHAKING, LARGE BUMPS IN THE ROAD CAUSE THE VEHICLE TO LOOSE TRACTION AND DEVIATE FROM LANE OF TRAVEL. STEERING MAKES A LOUD WHINING/CLICKING NOISE. STEERING WAS SERVICE IN JULY AND FOUND LOOSE MECHANICAL ITEM. 3 WEEKS LATER THE SAME NOISE HAS RETURNED. I BELIEVE THE WAY THE VEHICLE HANDLES BUMPS IN THE ROAD IS CAUSING THE STEERING ISSUE. DRIVING AROUND CURVES AND HITTING A BUMP OR DEPRESSION IN THE ROAD CAUSES THE VEHICLE TO SKIP ACROSS THE ROAD SURFACE AND MOMENTARILY LOOSE TRACTION AND STEERING CONTROL. DRIVING THE SAME XT5 LOANER CAR, DOES NOT HAVE THESE SUSPENSION ISSUES. ADDITIONALLY, THE AUDIO RANDOMLY STOPS WORKING, TURNING THE CAR OFF/ON ALLOWS AUDIO TO START WORKING AGAIN.

I WAS DRIVING IN TRAFFIC, ABOUT 45MPH, WHEN THE PARKING BRAKE CAME ON, I GOT A CHECK ENGINE LIGHT, SERVICE BRAKE ASSIST, SERVICE STABILITRACK AND ONE OTHER LIGHT ON. I MANAGED TO KEEP IT RUNNING ENOUGH TO NOT GET REAR-ENDED, BUT IT IS NOT SAFE. THE DEALER NOW HAS IT, AND I AM IN A LOANER. THE CAR HAS LESS THAN 2000 MILES ON IT, AND THIS IS THE SECOND CHECK ENGINE LIGHT (THE FIRST DID NOT INVOLVE THE PARKING BRAKE), BUT THE DEALER DID NOT FIND A CONCRETE PROBLEM FOR THE LIGHT. IS THIS GOING TO TURN INTO A RECURRING PROBLEM? IT IS VERY DEFINITELY NOT SAFE.

MULTIPLE ISSUES WITH GARAGE REMOTE CONTROL BUTTONS NOT FUNCTIONING. ISSUE WITH DRIVER SEAT NOT VIBRATING WHEN VEHICLE VENTURES OUT OF LANE WITH "LANE ASSIST" FEATURE ON. VEHICLE SHUT DOWN WHILE DRIVING ON HIGHWAY SENDING MULTIPLE WARNINGS ABOUT ENGINE MALFUNCTION, PARKING BRAKE ON, ETC.
