Automatic Transmission Problems of Mercedes Benz ML320

My ml 320 year 2000 mercedes-benz stoped suddenly while I was going 30 miles and hour. No sign of any problem (than engine stalled). This is scary and must be investigated. I almost hit a car. It did not start for 20 minutes and then it started. It will crank-start for 20 seconds and engine will stop again. Car started working fine after 45 minutes wait.

I was driving a mcercedes-benz Ml320 on August 02, 2011. The car engine suddenly and completely shut down while I was driving. I got stuck on the inner lane of homestead rd, cupertino, CA. Fortunately I was not on a highway, otherwise, I don't know what would happen to me. I got my car towed to the mercedes service. I was told that the crank sensor did not function properly. This costs me almost my life and $500. I think it's very dangerous to passengers if a car completely shut down while driving. Mercedes-benz should have done a better job to prevent this from happening. To my point of view, this is a design flaw. I want to share this experience to all drivers with the same model and have them watch out the same situation may happen.

This vehicle shifts automatically from drive to first gear when going at lawful high speed and sometimes low speeds, dangerously slowing the vehicle putting my family's lives and other drivers in peril on the road. The above incident occurred eight times within the last year and a half. The Mercedes Benz dealer could not find the problem.

Reference: vehicle complaint - 47046 in September 1999, we purchased a new mercedes-benz, ml-320. In 2003, the vehicle was part of a recall concerning a lower power steering hose and clamp at the radiator fitting. On August 7, 2007, while driving the vehicle, the lower power steering hose blew off losing all hydraulic fluid. We lost the power steering and had extreme difficulty steering the vehicle. The same problem has occurred with a family member's ml-320. In addition, the transmission has frozen four times in first gear. The mercedes dealer was unable to locate the problem. The vehicle was towed to the dealer, and they replaced the hose; however, we have not retrieved the vehicle from the dealer because we are fearful about driving the vehicle due to these recurring problems.

I have 2 complaints against mercedes Ml320 SUV. 1) with ignition off and key removed, the transmission shifter can be shifted to neutral and the truck starts to roll. It posts extreme danger to passengers, especially, kids left in a parked vehicle, as well as pedestrians in front or behind the vehicle, especially those standing in between this vehicle and another parked vehicle on a slope. 2) the well known power lock failure causes the manually locked doors (including child proof rear door locks) to be unlocked automatically whenever the vehicle starts in motion from full stop. It is due to the auto-lock feature which attempts to lock all doors when the vehicle starts to move from full stop (e. G stopping for red light). However, due to power lock failure, it cannot lock all the doors after 4-5 times and eventually unlocks all doors. This left children in the rear in danger of opening the doors while the vehicle is in motion. This problem happened to me twice; one at 9700 miles in 2001 and at 70,000 miles in 2007. I had written a letter to Mercedes Benz USA to complaint about the power lock and they just denied that it is a defect.

While driving 65 mph the vehicle decelerated down to 10 mph without warning. The cause has yet to be determined. Please provide additional information.

Upon pulling onto the interstate vehicle jerked then stalled. Consumer had the vehicle towed to the dealership for inspection, and mechanic determined that transmission failed.

Traveling at highway speeds of 70 mph up a steep grade on California interstate 5 on the section of the highway known as "the grape vine" elevation of 3000-4000 feet, headed north keeping pace with heavy traffic in the fast lane (far left hand side of the freeway highway ), in the afternoon of 2/16/04 at 2 pm with cruise control on the car ( 1999 merz, class hd,, body type ut ven 4jgab54e6xa123352) automatically shifted to a lower gear sending the rpms from 2500 to 3000-4000, this normal automatic action caused the car to stop all forward motion reducing both car speed and rpms to zero in the fast lane, the impact a "full engine shut down" a highly dangerous action in fast moving traffic with a short hazardous signaling notice. The car in July of 2003 performed in the same manner in the same section of "the grape vine" headed south in the fast lane with a different driver, not using cruise control the vehicle stopped all forward motion. Shortly arriving in palm springs California on the same day, the car again performed in the same malfunction. The car was taken to the palm springs mercedes dealership, the problem identified and presumably resolved. The problem is not resolved as stated for the purpose of this letter, it has occurred for the third time. This is a critical life threatening malfunction that demands immediate rectification.

Car was in park at the top of the driveway and rolled down my driveway down a hill and crashed into a tree to stop. The car maker sent an investigator out (after a month) who determined it was a defect in the transmission. (I am awaiting their report to me) car is not drivable.

The car was in drive, it suddenly went into reverse, accelerated at tremendous speed down my driveway, up onto my property where it hit a tree - still in drive. Damage was in access of $16,000. Mercedes denied any defect or malfunction after their inspection. I have since learned that an almost identical accident was reported in 2000 to another car - same year, make & model as mine.
