2018 JEEP WRANGLER — Complaint #2153440
Open-data reference.
NHTSA Complaint about ENGINE filed December 2, 2025
NHTSA complaint #2153440 (ODI reference 11702534) concerns a 2018 JEEP WRANGLER and was filed on December 2, 2025. The owner reports the failure occurred on October 17, 2025. The report was geocoded to Colorado based on the filer's self-reported location. The affected component is categorized as engine, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same JEEP WRANGLER cohort independently describe similar engine failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2018 JEEP WRANGLER shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
Started having misfire issues. Replaced spark plugs. problem continued. started having to add antifreeze regurlarly. 1 quart per 300 miles. multiple P0302 error codes. Dealer 1st tried to tell me was a loose coil pack. looked at it again and said needs a new head gasket possibly a whole new engine. 117,000 miles and this seems rediculous for a 60,000 dollar vehecle. Especially since Jeep already issued an extended 150,000 mile warranty for 2011-2013. with 100's of these same issues still happening on 2018's and latter they clearly did not correct the defect.
