Key Points

  1. After six months and a rocky start, our long-term 2026 Cadillac Escalade IQ's four powered doors have become a genuinely useful convenience, not just a party trick.
  2. A mid-test software glitch soured the experience, but a recent over-the-air update substantially improved the door control software and restored our enthusiasm.
  3. The episode highlights how software-defined features in luxury EVs live or die by OTA updates, and how Cadillac is using them to refine the ownership experience.

What Six Months With the Escalade IQ's Power Doors Revealed

When we took delivery of our long-term 2026 Cadillac Escalade IQ, the powered doors seemed like the kind of gimmick reserved for Rolls-Royce and Maybach buyers — a toy for the rich. But the Escalade IQ one-ups those luxury stalwarts by powering all four passenger doors, not just the driver's or rear doors. That novelty initially earned the system a Best Tech Award from our judging panel, but the real test was always going to be living with it day after day.

After a few weeks, the convenience became hard to give up. A gentle tug on the driver's door handle opens it fully; stepping on the brake closes it while you settle in. Exiting is just as easy — a light pull on the interior handle, and the door does the rest. The system even lets the driver open a passenger door from the driver's seat, a small but genuinely useful trick in tight spots like the LAX pickup loop or when double-parked.

Then came the rough patch. Over the past six months, the doors' software — like any complex electronic feature — proved imperfect. What started as uncertainty turned into affection, then frustration as glitches and quirks tested our patience. Just as we were preparing this update, Cadillac pushed an over-the-air software update that substantially improved the door controls, and the relationship was rekindled. For now, at least, the power doors are back in our good graces.

Why Cadillac's OTA Fix Matters More Than the Doors Themselves

Why Software-Defined Doors Are a Double-Edged Sword

The Escalade IQ's power doors are a textbook example of how modern vehicles are increasingly defined by software. Unlike traditional mechanical doors, these rely on sensors, actuators, and control code that can be refined — or broken — by an OTA update. Cadillac's ability to push a fix remotely is a genuine advantage: it avoids a dealer visit and keeps the ownership experience fresh. But it also means the feature's reliability is only as good as the latest software release, and early adopters effectively become beta testers.

What This Means for Cadillac's Luxury Credentials

For Cadillac, the Escalade IQ is a flagship meant to challenge European ultra-luxury brands. Power doors are a signature feature that signals technological leadership, but they also raise expectations. If the doors glitch, it undermines the promise of effortless luxury. The OTA fix shows Cadillac is listening and iterating, which is crucial for building trust with high-end EV buyers who are accustomed to white-glove service. Competitors like Mercedes-Maybach and Rolls-Royce offer power doors, but they don't yet offer four powered doors or the same level of OTA updatability — a potential differentiator if Cadillac can nail the execution.

The Broader Trend: Convenience Features as Brand Differentiators

In the crowded luxury EV segment, features like power doors are becoming table stakes for top-tier models. But as this long-term test shows, the real value isn't in the hardware alone — it's in the software polish. Automakers that can deliver seamless, reliable convenience features will have an edge in customer satisfaction and word-of-mouth. Cadillac's willingness to improve the doors via OTA is a positive sign, but it also highlights the ongoing challenge of software quality in the race to electrification and autonomy.
