I submitted an issue last week for the vehicle putting itself in park while driving and loss of brakes while driving. I brought the car to an authorized dealer and they told me they fixed the issue. It is now happening again. This is a major safety concern!

Several times, the car put itself into park while driving. Two times, the brakes failed while driving. The brake was pushed all the way to the ground, but the car would not stop.

Vehicle started up on its own and continued to run. Key fob was laying on a night stand. No messages were displayed in car. I was able to turn it off.

I am reporting a catastrophic engine failure on a 2023 Jeep Wagoneer (VIN: [XXX] ) that occurred within 163 miles of consumer delivery, suggesting a latent manufacturing defect present at the time of sale. The vehicle was delivered February 13, 2026 at approximately 29,750 miles. Engine noise was noted the same evening. By March 10, 2026, the vehicle was grounded at Farris Motor Company [XXX] ) at 29,913 miles — 163 miles after delivery. The vehicle remains inoperable after 60+ days. Stellantis STAR Case #XXX documents the following confirmed failures: collapsed lifters, failed camshaft, damaged rockers, and scored cylinder walls. Technician notes in the official STAR Case record state the engine oil contained metal contamination so severe it "looked like paint." Borescope imaging confirmed scoring on cylinder walls. Stellantis has thus far refused to authorize a full engine replacement, instead directing the servicing dealer to replace only individually identified failed components — despite the fact that metal contamination of this severity compromises the entire lubrication circuit, including both turbochargers. The servicing dealer (Farris Motor Company) has independently advocated to Stellantis for full engine replacement and agrees the partial repair is insufficient. I am reporting this failure to NHTSA to document the defect pattern and request investigation into whether other 2023 Wagoneer vehicles with the 3.0L Hurricane engine may be experiencing similar latent valvetrain failures.

This vehicle has had 2 incidents where the engine overheated. In both instances, the thermostat has been replaced under warranty. Due to this most recent overheating event, the repairs were over $1750 excluding the portion of repairs under warranty. There were no warnings before the engine overheated, and the vehicle was being driven on the freeway at appropriate speeds. This is not the first time this vehicle has overheated.
