“While at a stop light, with start/stop active, I released the brake, which should have reactivated the car. Instead, it shut down. I got a quick transmission service error on the dash. Once I put the car in park and turned it off and then on again, it functioned properly. I. The meantime I was being honked at from everyone missing the green light behind me.”

“The wagoneer while driving twice has shut off, gone into park, and emergency break turned on. The problem is shutting off on its own while driving. This could cause a wreck obviously if happens at a higher rate of speed. Thankfully both times I was at about 5-10mph and nobody was behind me.”

NHTSA complaint #11658748, filed 2025-05

“I worry about the reliability of the vehicle. I have had it since June of 2023 and since I have purchased the vehicle, I have had nothing but issues. It has now been towed twice back to the dealership for engine issues. I have tried to reach out to many different people to try and get this resolved with no luck. I have 2 small children that rely on my transportation along with getting myself to and from work. …”

“Our 2023 Jeep Wagoneer overheats (indicates excessive oil temperature and low oil pressure) repeatedly (~20 times since we've owned the vehicle) under normal freeway driving causing a safety issue by creating the need to rapidly slow and exit the roadway to prevent vehicle engine failure. The issue occurs during sustained freeway driving around 60-65 mph. The car feels like it is not properly shifting to the next gear and the RPM lingers around 3000rpm - 3500rpm. …”

NHTSA complaint #11718126, filed 2026-02

“Our vehicle was purchased in December of 2025. Aprox. One month after purchase the vehicle unexpectedly turns off while driving. Fails to start. Along with multiple other issues. Its has been in the shop over the course of that time more than four months and is in the shop current day 14sept2026. We have spend roughly $10,000 to date and continue to be financially and emotionally ravaged. Sealants has been no help. The purchasing dealership also refuses to make it right.”
