2023 GMC Sierra 1500 Park Assist Under Constraint

The 2023 GMC Sierra 1500 is the fifth model year of the current fourth-generation pickup nameplate, ushering in only a few small changes and updates as compared to the fully refreshed 2022 model year. Now, however, GM Authority has learned that some parking assist features are currently under constraint for the 2023 GMC Sierra 1500.

According to GM Authority sources, some units of the 2023 GMC Sierra 1500 that would normally be equipped with Rear Park Assist (RPO code UD7) and Front and Rear Park Assist (RPO code UD5) will not include these features.

Normally, Rear Park Assist is available for the 2023 GMC Sierra 1500 Pro trim level in conjunction with the 1SA Safety Package (RPO code PQA), while SLE and Elevation trims normally offer the feature in conjunction with the Sierra Safety Plus Package (RPO code PED).

Meanwhile, Front and Rear Park Assist is normally available for the 2023 GMC Sierra SLT in conjunction with the Sierra Safety Plus Package (RPO code PED), and included as standard for AT4, AT4X, Denali, and Denali Ultimate trim levels. To note, 2023 GMC Sierra AT4X, Denali, and Denali Ultimate trim levels are unaffected by this constraint.

It’s also worth noting that the 2022 GMC Sierra 1500 is also affected by constraints for these two parking assist features. The difference is that while 2023 GMC Sierra 1500 AT4X, Denali, and Denali Ultimate trims are not affected by this constraint, the 2022 model-year Sierra AT4X, Denali, and Denali Ultimate trim levels are affected.

One of the big updates for the 2023 GMC Sierra 1500 is the introduction of the new 3.0L I6 LZ0 turbodiesel Duramax engine to the powertrain lineup. The new LZ0 engine will replace the 3.0L I6 LM2 engine option, and offer the same specs. The LZ0 is considered the “second iteration” of the Duramax 3.0L six-cylinder engine, with the LM2 being the first.

As a reminder, the 2023 GMC Sierra 1500 offers four engine options total, which, in addition to the new turbodiesel six-cylinder already mentioned, also includes the turbocharged 2.7L I4 L3B gasoline engine, the naturally aspirated 5.3L V8 L84 gasoline engine, and the naturally aspirated 6.2L V8 L87 gasoline engine. Under the skin is the GM T1 platform, while production takes place at the GM Silao plant in Mexico and the GM Fort Wayne plant in Indiana.

  1. This is how it started in 2022 when I ordered my Dinali ultimate that I eventually canceled because of all the constraints so you haven’t even started production in 2023 and they’re already constraints come on GM

    I would agree. IT’s a mass of confusion-with no price considerations for missing features. It’s a token $50.00 discount. Then-there will be more confusion if/when chips become available to install on some features missing from your truck. The bottom line is don’t order any new truck unless you current one has literally blown up.

  3. Here is my question,why is a truck equiped with all these safety feature, and a vechile that is used to transport humans, like the Express anad Savanna see nothing of these features—-where I think they should be availble before any truck gets them. Tells us it’s all about money and not about safety of people. Because trucks get sold in large numbers, and thats where they money comes from.

  4. Real question for 1000 points is when they change 5.3 and 6.2 engines ,to survive warranty period ,both this engines are garbage, junk, not worth to even think about. Nobody cares about all this sh*tty cosmetic changes what is still 5 y behind competitors, they just need to produce reliable trucks what survive apocalypse, not junks what they producing now
