Where the 2023 GMC Sierra AT4X fits into the hierarchy of off-road trucks

The world of off-road pickups sure seems like it's getting crowded, but the reality is that half-ton trucks were always pretty capable, even with what seemed like fairly basic 4x4 packages. It wasn't until recently that manufacturers really started to carve out different off-road niches for their mainstream pickup offerings. With the introduction of the 2022 GMC Sierra 1500 AT4X (alongside its mechanical twin, the Chevy Silverado ZR2), the crowd has grown even thicker. Even we have trouble keeping up with the increased segmentation of off-road pickup trucks, so we threw together this handy guide to help you understand just where these various packages fit into the broader pickup hierarchy. Let's dive in.  Your basics If we say "Z71" or "FX4" to you, both will probably ring a bell. That's because they've been around a few days short of forever and their respective customers have grown so used to these package codes that OEMs got into the habit of just plastering them on the side of so-equipped truck beds. Anybody who sells a pickup truck offers some sort of basic off-road prep package like this one. Z71 is found on GM vehicles; FX4 is Ford's. Ram just calls it "Off Road Group," but no matter what you call them, they're all pretty similar.  Typical upgrades for this category include some additional ground clearance, a basic all-terrain tire, heavy-duty suspension upgrades and likely either a limited-slip or locking rear differential. These are pretty handy for anything beyond a rutted dirt road. On newer trucks — especially on higher trim levels — you'll probably also get some dedicated off-road drive modes.  Mid-range This is where things start to get interesting. To qualify for this category, a locking rear differential is a must. Most of the names in this segment are well-established too, though some (Nissan Titan Pro-4X, anyone?) may not necessarily be on your radar. The Toyota Tundra TRD Pro checks in here, as does the Ram Rebel, Chevy Silverado Trail Boss and GMC Sierra AT4 (no X!).  Realistically, if there's somewhere you need to go and one of these trucks won't do it, you might want to consider a helicopter. But it's 2021, and our thirst for capability is strong, so of course, there's a way to spend more of your money on this type of thing. Onward! Entry-hardcore Here we are, the home of the new 2022 GMC Sierra AT4X and Chevrolet Silverado ZR2. This is a tiny niche, otherwise occupied only by the Ford F-150 Tremor.

2020 Ford Explorer, Lincoln Aviator reportedly facing numerous QC issues

A lengthy report in the Detroit Free Press delves into a range of quality control issues confronting the 2020 Ford Explorer and its luxury platform sibling, the 2020 Lincoln Aviator. Freep says it's been following the issue for two months, tapping various unnamed sources for information on the automaker's unorthodox route to resolution. Seems the problem is Explorers and Aviators leaving the production line at the Chicago Assembly Plant with flaws in areas like the chassis, transmission and suspension, said vehicles trucked to Ford's Flat Rock Assembly Plant (FRAP) outside of Detroit for repair. The estimates range from 10,000 to 18,000 vehicles affected, numbers so high that Ford has sought help from Roush Engineering in nearby Allen Park, and brought workers and managers from other plants in the Midwest to FRAP to get vehicles repaired and shipped to dealers. Ford hasn't shared the nature of the problems with anyone outside the company, including dealers and customers. Freep's sources are said to include workers who have provided photos of certain vehicles and of tents used to house parts at the FRAP repair site. The Explorer chassis allegedly has an unidentified problem that engineers are using X-rays to diagnose, and the transmission is having problems sensing when it's in park or going into park. Both the Explorer and Aviator have come off the line with HVAC units that only blow hot air. And the Aviator's height-adjustable suspension enters failure mode for unknown reasons. These come on top of quotidian mishaps common to every new vehicle, but that are meant to be sorted in pre-production, like missing emblems and trim pieces. They also come on top of a recall in early August issued for the Explorer and Aviator concerning the instrument cluster and parking brake, and another at the end of August over rear seatbacks that could collapse in a crash. An automaker spokesperson told Freep, "Making updates to preproduction models based on all-new platforms as they roll off the assembly line – is standard industry practice." Except these aren't pre-production, these are early production vehicles that paying customers and dealers are waiting for, and some of the affected vehicles have been pulled off dealer lots. Dealers say they are fine waiting for the trucks to get sorted out, and they'd rather have Ford fix the problems before the SUVs go to customers.
