“2nd timeinto daeler for transmission problems. Will have problems shifting then the check engine light comes on. First time dealer unsure of the cause or how to fix had vehicle in shop almost 2 weeks. 2nd time, dealer has had vehicle over 2 weeks and still not fixed ,said could be 1 of 3 things. They have replaced 2 of the 3 so still have 1 to go and I guess I will be out of the vehicle another week for a total of 3 weeks if this fixes the problem.first incident was around 3000 miles second incident at 16000 miles.”
NHTSA complaint #10040866, filed 2003-09, 16,559 miles“Vehicle won't engage when shifted into drive and reverse (acts like it's in neutral). Only happens when vehicle is cold (under 30 degrees outside). Sometimes will slam into gear causing the vehicle to lunge forward. Very dangerous in our opinion. Vehicle has 146 miles. Dealer had vehicle twice for 2 days each and say they can't reproduce the problem.”
NHTSA complaint #10014081, filed 2003-04, 25 miles“I bought the truck on a cloudy day. When the sun hit it, it had swirl marks burnt into it from where it was buffed at the factory. When turned in they buffed it again. Now that it rained it still shows all. Another problem is the transmission. It has severe lag and sometimes won't shift at all.”
NHTSA complaint #10055022, filed 2004-01, 1 miles“The contact owns a 2003 Mitsubishi Montero Sport. While driving over 30 MPH, the vehicle would jerk backwards and hesitate. Whether the vehicle was idling or in park, the contact smelled a strong odor of burning oil. The dealer stated that the failure may be minor and could not assist because the vehicle was not covered under warranty. The contact intends to take the vehicle in for service soon. The failure and current mileages were less than 96,000.”
