One of the longest-running issues with Jeep’s halo Wrangler off-roader has finally been resolved, following a successful crash test conducted by the Insurance Institute for Highway Safety (IIHS). Bizarrely, the solution to an issue that has plagued the current-generation Jeep Wrangler since 2019 was surprisingly straightforward. What The Problem Was… IIHS / YouTubeIn the IIHS-conducted evaluation dubbed the "driver-side small overlap crash test," a four-door Wrangler, among the cheapest manual transmission SUVs you can buy in 2026, is propelled into a crash barrier at up to 40 mph, with the impact focused squarely on the driver's side wheel and front corner. As the above image shows in dramatic fashion, previous tests conducted in 2019 and again in 2022 found the Jeep was at high risk of flipping over from the impact. Rollover problems are further amplified by the Wrangler's narrow wheelbase and high center of gravity, though that's an issue for any small off-roader.Sadly, it’s also not the first time the Wrangler has suffered this setback. Alongside independent IIHS testing, in 2020 the National Highway Traffic Safety Administration (NHTSA) labeled the off-roader's tip-over risk at just under 27%, far higher than most other midsize SUVs in its segment. This was particularly worrying, given that, famously, the Wrangler’s roof panel and doors can be removed for open-air driving at the customer's desire.This, plus the lack of side airbags, increased the chance of driver and/or passenger injury in the event of an accident. Occupants possibly being ejected from the vehicle as it rolled was a particular concern. …And How Jeep Eventually Solved It Following another round of updates by Stellantis, however, the Wrangler has now been given an Acceptable rating for the small overlap crash test. Upon impact at the same speed, the above video shows the SUV staying largely stable, skidding to the right instead of tipping. As a result, the IIHS gives the 2026 Wrangler, the results for which had already improved significantly by 2024, a Good overall rating.The frame rail upgrade has also been implemented on the Wrangler’s sister model, the Gladiator. What exactly does this frame rail upgrade entail? CarBuzz reached out to Jeep, which provided the following statement:"The frame rail reinforcement acts as a structural enabler to support an enhanced impact strategy for this test mode. It acts as a deflector when the wheel and tire are engaged in this particular crash mode."Insurance Institute for Highway Safety (IIHS)Ironically, while the roll-over issue has finally been sorted, and while the vehicle is said to offer solid protection overall, the Wrangler is not out of the proverbial woods yet. Results from a passenger-side test, official footage of which the IIHS has not yet shared, show that the front passenger’s right foot and leg are still at a “high risk of injury” should the Wrangler be T-boned.It should also be noted that the IIHS’ Acceptable rating only applies to 2026 Jeep Wranglers built after October 2025. All examples produced prior to that date are still at high risk of tipping over.
