2023 Jeep Wagoneer: engine failure

Filed Oct 16, 2026 · Engine · KY

The thermostat suddenly failed, causing extensive engine failure. The engine failure was the direct and unavoidable consequence of a known manufacturer defect explicitly covered under Customer Satisfaction Notification 26B and TSB 09-006-25 / RSU 25-047 which should have replaced my thermostat or been a recall.

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 the federal safety agency 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.

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. After a few minutes at this sustained RPM the engine temperature gauge slowly climbs until the overheating warning light comes on and it typically followed by a low oil pressure warning. We have taken the vehicle to a Jeep dealer twice. They have tried to replicate the issue and have not been able to. We suspect that they are not driving in long enough (30-40min) to be able to replicate the issue. They also say that they are not able to pull up any error codes from the vehicle from an ODB scanner. They say they can't diagnose the issue with out an error code and seam to be unwilling to explore the issue further. Most recently we've purchased our own ODB scanner to try to gather any error codes because the Jeep dealer doesn't seam to want to investigate further without us gathering error codes for them. Today we drove the car for about 45min on moderately hilly terrain at around 60mph and produced three separate overheating / low oil pressure error incidents while the ODB scanner was plugged in. The ODB did not indicate an error code on any of the three incidents. We are frustrated because Jeep and their dealers have left us in a situation where we have a dysfunctional vehicle and seam to be unwilling to take reasonable measures to resolve the problem.

I wes driving and the over heat light came on in pulled over and had car towed to dealer. The dealer pulled the report and they said I needed a new engine and that I drove 40 miles in limp mode. There was no lights or indicators that there was an issue until the car overheated in that time it was only drove 3 miles. They cannot pinpoint when the light would ha e turned on and now I am stuck with a broken engine that stelantis is refusing warranty coverage but the car failed to alert me there was an issue

The Wagoneer with 20,000 miles very suddenly started to overheat, then quickly redlined on the dash board. Car shut down at dark night intersection. Needed to be towed to dealer. Dealer diagnosed that the ENGINE needs to be replaced. WTF. Waiting for Jeep Claims rep to contact me. Case # 94698805. No word on ETA of replacement engine. Expecting a long term rental car. NOT HAPPY I'm financing at $800 per month car in shop for who knows how long. Dealer claims they have 2 other Wagoneers on the lot with same engine verdict. Is there a BUY BACK policy available? lol.

In June of 2024 the engine hot and oil pressure low light came on in the middle of a busy intersection and the car went limp had to get it towed to dealer. They replaced engine thermostat. March 18, 2025 was driving down interstate at 80 mph when wheel locked up and brakes. The power steering and brake light came on with a red exclamation point and I was unable to barely move the wheel and had to continue another mile until highway exit. If the highway curbed could have been deadly. Towed it to Jeep and they said upon checking it all looks good. Now I’m suppose to drive my five kids around and hope that never happens again with no explanation from dealer on what exactly caused it.

Engine overheated and oil pressure low warnings came on suddenly and lost power. I had my two grandkids and was on a dark country road with ditches and no shoulders. Pulled off at the next cross street to get to safety. Was stranded at night in a rural area with my [XXX] and [XXX]. Had to have vehicle towed and wait for someone to pick us up. Thermostat failed, which is a known problem but my VIN wasn’t listed on the 26b notice. Engine was damaged beyond repair. It took three weeks for them to replace the engine. The morning after I picked up the Wagon, the brake warning light came on when the grandkids were in it again. The dealership told me to have it towed. They said they spilled brake fluid when they replaced the engine and refilled it. I paid nearly 100k for this unsafe car! There is no excuse for not replacing a cheap $50 thermostat to avoid this issue. Why haven’t they issued a recall?
