Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I'm the original owner of a stock 1991 Jeep Wrangler with 2.5 liter engine at 106,000 miles. The fuel rail has failed and is leaking at factory installed plugged end of the rail at the opposite end from the fuel pressure regular. The leak is between the plug and the rail. This should have been a brazed sealed end or a threaded plug instead of a compression fitting of a plug. The leak produces a spray of gasoline near the exhaust manifold which could lead to a fire. …”

NHTSA complaint #11563019, filed 2024-01, 115,000 miles“My fuel tank is the problem. It first started leaking in 1991 when I first got my Jeep. It was repaired. Then it started leaking again in 1996, and I took in, it and the recall covered that repair. Then again in 1998, the tank leaked again. Same problem each time. They said it was the fuel send unit, but each time they had to replace the gas tank completely. The only time the manufacturer paid for it was when I took it in under the recall. The other times, I paid for it. Because it is the gas tank, it could easily lead to fatalities. …”
