There are 3 owner-reported engine complaints for the 2024 Jeep Grand Wagoneerin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Our car overheated because of a faulty thermostat leaving us on the side of the road stranded with kids in the car. We had to have the car towed.
While driving my kids to school on the freeway I received an alert telling me that my engine was overheating! I was barely given any warning of the rising temperature to allow myself to pull over safely. It never informed me it was rising, only when it was redlined near the max engine temp to which I had to immediately find a place to pull over. I didn't have enough time to get to the next exit 1 mile away, and had to pull over in an unsafe area and turn the car off until the engine cooled down while cars whizzed by us. Once cooled down enough, I was able to drive 1 mile to the next freeway exit but had to immediately pull over again into a center median as it was again overheating very quickly. My local dealership came to get the car and took my kids to school and me home while they inspected it and found a failing thermostat and water pump. I have only had the vehicle for 9 months and it only has 15,800 miles! This should not happen, at all, on a $135,000 vehicle. I also happened to notice a failing battery (no audio warning of this) on the display while scrolling through the menu looking for the engine temperature! So a brand new car has a failing battery, thermostat and heat pump..... unbelievable.
n early January 2025, we purchased 2024 Jeep Wagoneer L that began displaying check engine warnings and experiencing significant performance issues within the first week. The vehicle was brought into the dealership (Golling Jeep in Bloomfield Hills, MI) on multiple occasions—first on January 22nd and again on February 7, 2025—for drivetrain-related concerns, including rough idling, and warning lights. The vehicle was returned after temporary fixes, but the issues quickly recurred. On February 21, 2025, the vehicle was returned to the dealership and has remained there ever since. Despite repeated diagnostic and repair attempts over the last five months, the dealership has been unable to resolve the issue. As of July 2, 2025, their latest communication indicates that a complete engine replacement may be required. The symptoms included drivability issues and engine malfunction indicator lights. The vehicle’s reliability deteriorated to the point where we felt unsafe using it for family transportation, especially on highways or long trips. The issue has been inspected and repeatedly confirmed by certified dealership technicians. The vehicle is available for inspection. There were no reported accidents or injuries, but the repeated and unresolved engine issues present a clear risk to occupant safety and undermine vehicle performance. This ongoing situation has rendered the vehicle inoperable for over 150 days while under warranty, with no final resolution provided.
