2018 GMC Acadia

When I’m driving on the highway, I get a message on my dashboard saying steering assist reduced, drive with care. I have taken to the GMC dealership and they will not cover this repair even though it would be covered for 2021 GMC. When this happens, my car makes a loud noise and my steering wheel does not feel right. I do not feel safe.

The contact owns a 2018 GMC Acadia. The contact stated while driving at undisclosed speed, the steering assist reduced warning light illuminated. The contact's husband attached a portable diagnostic tester to the vehicle, and P0128 was the failure code. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline and report the failure. The failure mileage was approximately 78,000.

The warning light for a steering assist needs service came on the dash. The dealer had a code (po128) that pertained to a bad thermostat and coolant temp. sensor. The steering assist could have failed, along with possible engine damage. The dealer replaced the thermostat and the coolant temp sensor. Their were no police or insurance reports needed.

Battery saver ignited comes on and and the entire dash flickers and turns off ! This happened in a middle of an intersection and I could move my car. We jumped it and went to the nearest auto zone replaced the battery . It was pulling 89 amps . The next day it popped up again and we replaced the alternator. Upon replacing this there was oil everywhere! And we don’t know where it is coming from . Now shift into part light comes on !

All of this has been going on for a while but it's gotten to the point of dangerous. The Shift to Park keeps coming on preventing me from shutting the vehicle off even though it's, in fact, in Park. Then, "Steering Assist Reduced Drive With Care" keeps coming on. This will come on and off. Preventing the engine from heating up like it needs to be. Then the transmission keeps slipping. Was nearly rear-ended on the highway with my child in the car when it decided to start driving really rough and wouldn't allow me to shift to the next gear. This is also an ongoing issue. Another time I was almost hit in the side when this randomly happened on crossing the highway. This is absolutely absurd! I have had MUCH older vehicles without all these issues with many many more miles! I can't count the amount of times this has caused us serious hazards not to mention almost costing me my JOB! Interestingly enough, the same year/make/model has been recalled for the exact same issues yet for whatever reason GMC says MY model "was not affected by the recall". Funny how it's having the EXACT same issues as the ones on the recall list! GMC needs to fix this before they cause people to die! I'm a healthcare worker and this is disgusting!

The contact owns a 2018 GMC Acadia. The contact stated that while shifting the gear shifter into park(P), the "Shift to Park” message was displayed on the instrument panel.

In addition, the contact stated that while driving at various speeds, the steering wheel would become sticky with the "Steering Assist Reduced - Drive with Care," message displayed on the instrument panel. The contact stated while driving at various speeds, the infotainment system glitched and performed independent functions, causing the driver to be distracted. The contact stated that the infotainment system was replaced when the vehicle was purchased due to the failure; however, the failure recently recurred. The manufacturer was made aware of several failures and informed the contact that there were no recalls on the VIN. The vehicle was not repaired. The failure mileage was approximately 105,000.
