2018 GMC Acadia mileage at failure

181 of the 398 complaints on file for the 2018 GMC Acadia give the vehicle's mileage when the problem happened.

Mileage at failure by component, from owners' complaints to NHTSA
Component	Median	Middle half	Based on
Power Train	Median 45,000 miles	Middle half 20,000–70,000 miles	Based on 93 complaints

A component's median is its 50th percentile, and its middle half runs from its 25th to its 75th percentile.

Owners give the mileage themselves, often as a round number, and NHTSA doesn't check it. A complaint that names several components counts under each one, and mileages that can't be right, such as 999,999, or 50 miles on a five-year-old car, are left out.

These figures describe the complaints owners filed. They don't predict when a particular vehicle will have a problem, and vehicles that never had one aren't counted.

Most complaints NHTSA received since May 17, 2021 give no mileage. So that they aren't undercounted, each one received since then that gives a mileage also stands in for those that gave none, which can put a component's median above most of the mileages it is based on.

ODI #11767917

Incident: October 30, 2025 · Filed: September 29, 2026

I get error electric Steering assist reduced or unavailable drive with care at around 84234 miles on my car . Upon looking up problem on Internet it has to do with the Thermostat. I also found where Gm has a bulletin N252508350 which only seems to cover certain vehicles with the same problem. This seems to happen at all different miles driven on vehicles. I don't see how Gm can get away with only fixing certain vehicles with this safety problem when it shuts down the electric steering assist . This problem from what I can find on the internet is common to all years from 2017 up in Acadia with the 3.6L engine . The Thermostats seem to be defective and I feel Gm needs to address this problem for all of these vehicles . Not just for there special bulletin N252508350 which covers some vehicles in 2021with 3.6L engines. If the engine design was like the old engines and easy to replace the Thermostat by just taking out 2 bolts , I would say no problem I will replace it .But when you have to take half the Engine apart just to replace a 20.00 part that is defective that affects the steering of the vehicle, they need to have a safety recall.
