We noticed that the engine was smelling hot, but no warning lights were on, so we made an appointment with a Mitsubishi dealer, while driving it into the shop it began to overheat. After stopping several times to cool off the engine we made it to the dealer only for the car to just then get a check engine light on and stall completely out. We then found out that it was a hole in the radiator and was not covered under the power train warranty. We could not afford the 630 dollars that they wanted to charge us so we decided to have a known mechanic do the work. When the radiator was pulled out we found that since the air conditioning and coolant was behind the radiator it caused rubbing on the bottom of the radiator causing a small pin hole to be rubbed into it. We are working on having it repaired with a licensed radiator shop and replacing. The issue with us is that if the air conditioning continues to rub it will cause more holes and more problems.

On September 1, 2007, I had been driving on the highway at approximately 60 mph for approximately 15 miles when the air conditioning suddenly began blowing hot air and the temperature gauge went above "H" immediately. I turned the air conditioning off, exited the highway immediately, stopped the car, and attempted to restart the car to remedy the problem, but when the vehicle was restarted the car was still past the "H" on the temperature gauge. I drove the vehicle to the first repair shop, and they discovered that the bottom half of my radiator had disintegrated and fallen off the bottom of my car, along with all of the coolant and other necessary parts. The radiator, thermostat, and coolant all have to be replaced. The mechanics stated that they have never seen anything like this happen to a car that wasn't at least 15 years old. My vehicle is a 2004 that I purchased in March 2004.

Endeavor 6-cyl

  • Automatic transmission
  • 23,250 miles
Road debris caused a complete failure of my radiator because it is poorly designed with no protection from the front of the vehicle. There is no grill protection in front of the radiator so stones and debris are free to hit the radiator directly and puncture the tubing. This happened to me on 09-22-05. It will cost me $650 for a newly installed radiator from Mitsubishi. The problem I am having is the design flaw which leads to safety issues. I am not guaranteed this won't happen again after my new radiator is installed because Mitsubishi does not make an accessory to fix the design flaw. This is a safety issue because it will most likely happen on the highway at higher speeds, not city driving. Mitsubishi should be made aware of this complaint immediately.

Endeavor 6-cyl

  • Automatic transmission
  • 9,591 miles
Early on a Saturday morning, I was driving on a relatively traffic free L.a. freeway. I happened to look down and notice the check engine light on and the temp gauge pegged. There was no other indication of a problem. Fortunately I was able to get off the freeway before the car stalled. Upon inspection a small hole was found in the front of the radiator. The problem seems to be a large grill opening with no screen or other protection. Normally the radiator is protected by the ac cooler. But in the case of the Endeavor, an inch of cheap fragile aluminum radiator is left exposed to even the slightest of road debris. Since the stopping of a vehicle on a crowded freeway could result in a serious accident this needs to be corrected by the manufacturer. Radiator was replaced at customer?S expense.

Endeavor 6-cyl

  • Automatic transmission
  • 8,000 miles
Car was traveling at 70 mph on highway-check engine light came on and within minutes car decelerated and stalled in middle lane right before major access ramp with heavy traffic flow. Car completely stalled. Unable to get over to shoulder due to traffic. There was definitely a potential for injury, collision from behind etc. Radiator busted, plugs replaced. Now engine heads have been dissembled and in the process of being replaced. Car has been out of owners possession for 2weeks.
