NHTSA complaint #11755207

Owner complaint summary

My 2023 Jeep Wrangler 4xe High Altitude received FCA Recall 68C. Since the recall was completed, the vehicle has experienced repeated and unpredictable reductions in available propulsion during normal driving. The problem is most noticeable when accelerating to merge onto highways, enter traffic, or pass slower vehicles. During these situations, I depress the accelerator expecting normal acceleration, but the vehicle frequently provides significantly reduced power. There is a noticeable delay before the gasoline engine produces sufficient propulsion, leaving the vehicle unable to accelerate as expected for several seconds. Based on my experience, the condition is significantly worse during hot weather. As outside temperatures increase, the hesitation and reduction in available propulsion appear to occur more frequently and are more pronounced. This has caused me to lose confidence in the vehicle's ability to accelerate when needed. This condition creates a serious safety hazard because surrounding traffic continues at highway speeds while my vehicle is unable to accelerate as commanded. In [XXX], this hazard is particularly acute because many interstate and highway entrance ramps are relatively short, requiring drivers to accelerate quickly to merge safely into traffic traveling at highway speeds. When the vehicle unexpectedly limits propulsion or delays engaging the gasoline engine, there may not be sufficient distance to reach the speed necessary to merge safely, increasing the risk of a collision. The same issue also affects attempts to pass slower vehicles on two-lane highways, where timely acceleration is essential for safe operation. The vehicle does not display diagnostic trouble codes or warning messages when this occurs. Because no diagnostic codes are stored, I have not taken the vehicle to the dealer, as other owners have reported that dealerships are unable to identify or repair the condition in the absence of fault codes.
