Second owner of this vehicle and had for almost a year. Driving son to school and suddenly heard a loud rattling noise under hood. Took directly to mechanic and found out timing chain was going. Mechanic said he had seen this problem a lot in this model and around the same mileage.
The car was idling rough and the "service engine" light kept coming on, even after I had the auto repair shop (pep boys) check and fix things. They advised me to go to the Ford dealer, and said it may be the timing chain. Future Ford ran diagnostic, said it may be timing chain but have to open engine to verify. Estimate for repairs $1500 to open engine and $2500 to fix). Did not have work done yet. The engine has a loud rattling sound that started suddenly and has gotten worse, and increases upon acceleration. There is an oily smell. At stop light when idling, the idle is slow and a loud knocking sound - idle sounds like car is about to shut off. The normal idle sound for the car is smooth and like a soft hum. Called Ford to see if there is a recall for this problem, as there are many complaints similar to mine that are listed on the Ford website about several years of the Ford Explorer. Mileage now is 150,000 miles. Ford said there is no recall, but keep receipts for work done in case of one in the future.

2003 Ford Explorer. Consumer writes in regards to humming/whining noise in the rear end of vehicle and a frequent leak in the differential. The consumer stated several components such as the ring an pinion, bearings, seals and gear and pinion were all replaced. However, the issue remained unresolved. Also, the rear hatch was cracked. When the consumer inquired about a replacement and its cost, the dealer advised against the replacement/repair as the new hatches had the same problem. The vehicle overheated and had to be towed to the dealer. A diagnosis revealed a damaged thermostat housing.
Since the vehicle was purchased, my husband and I have noticed the engine makes a whistling noise in cold weather between 25-40 mph. The noise used to go away after driving for approximately 15-20 minutes. It no longer does. So far this winter, I have noticed the engine continuing to make the whistling sound entire 35-45 minute commutes. The speed now ranges from 25-70 mph and comes and goes throughout the drive. The dealership has kept the car for a few days (in previous years) and have not had a fix for this issue.
Rear glass opened while driving. Loud whistling noise coming from under dash/engine. No power. Stalls on take off.
