11 problems related to power train have been reported for the 2007 Mercedes Benz E350. The most recently reported issues are listed below.
At about 87,000 miles, the car is essentially useless because of a known defect. The balance shaft, engine intake manifold and transmission conductor plate need to be replaced. Mercedes will not take responsibility even though there was a class action lawsuit.
The engine dies suddenly while driving. Cause unknown. Car will restart without trouble, but the suddenness of the problem is really startling and could be very dangerous on the freeway or on a winding road at speed.
While driving on freeway, engine suddenly revved high and almost red-lined on rpm gauge. Exited freeway and rpm (while lowered) was still high. A 3rd party mechanic diagnosed transmission valve body failure and advised on replacement. This must be a a known issue because mechanic asked that in order to replace the part a valid personal id must be recorded as part of the parts replacement per mercedes.
The automatic transmission would not shift properly. Very dangerous. It is a seven speed automatic transmission but seemed to stay in a high gear so the vehicle did not accelerate. It would not go into reverse. It occurred on a major highway. The me dealer said the repair will be about $2300 this should be a recall. Safety hazard.
30 Aug. 16 took my 07 E350 with 29427 miles to the dealership because the check engine light came on and the car was hard starting. After arriving I informed the service writer the car had shut down while driving. We were proceeding through a busy major intersection when the car shut down. Luckily it started so we could safely exit the busy major intersection. After a diagnostic test was ran, I was informed the crankshaft hall sensor was defective. Additionally, the engine control unit, engine wiring harness, crank sensor and various other components are oil soaked. I notified Mercedes Benz to be told the car was out of warranty. Mercedes benz should be held accountable for the unsafe defective materials they use. The above issues are a danger to the occupants and general public as well. The defective oil soaked wiring harness is can cause a fire. The car shuts down while driving is dangerous.
Check engine light came on. Took the vehicle to the local dealer and they found codes 1200, 1208, p0016 and p0017. Worn balance shaft sprocket. Doing research online turns out there are hundreds and hundreds of affected mb customers. Mercedes knew of this problem as early as 2007 but has not publicly addressed this issue or issued a recall. The bill to fix this issue is over $4,000, some people report the dealer quoting them over $10,000. My price to fix this is $5,995. My complaint is that this is a known issue by mercedes. Knowingly they installed, and kept installing, parts that wear out prematurely leaving customers with an unfairly large bill to correct their mistake.
While driving and changing gears from first to second, at or around 10 - 20 rpm my engine became uncontrollable and jerked sporadically. I could not control the vehicle until it changed into 3rd gear and then began to drive as normal. The car does this repeatedly now until I feel it has become unsafe to drive. The jerking is random so I don't know when to expect it and what to do when it happens. It has caused me to veer off the road occasionally.
The front inner tires get cupping over the time, I have to replace them every 10,000 miles. All the suspension parts are new put still the problem going on. It is a manufacturing problem with the heavy engine get the load on the power train and with the time it losing and make the tires cupping from the inner side.
Tl- the contact owns a 2007 Mercedes Benz E350. The contact stated that the vehicle would jerk violently when shifting gears. Also, while driving 20 mph the vehicle would not shift into second gear and stalled without warning. The vehicle was taken to the dealer for inspection but they provided not assistance. The vehicle was not repaired. The manufacturer was notified and filed a complaint and stating that the vehicle was not under warranty. The failure mileage was 113,000. Kmj.
I bought this car about 4 months ago. This car has been serviced religiously at the local mercedes dealer and there has been "no know problems". On a Thursday I noticed the car shifting a little funny so I had my husband drive it just to be sure. He noticed the same erratic shifting. On Saturday I dropped the car off at the mercedes dealer (same dealer it has always been serviced at). When I parked the car I wanted to check each gear just to make sure and what do you know. . . It would not shift into reverse. Later that day I had to call mercedes to find out what was going on with the car and they proceeded to tell me the car had metal shavings in the transmission pan and would need a new transmission. The quote for a new transmission is $5800!!! I don't understand how the car did not give me any warning nor an indicator light. The car only has 60k miles on it and in no way should need a new transmission. Also, keep in mind the transmission was serviced at this same mercedes dealer at 39k miles. Something is not right and I want answers. I am completely shocked and so upset.
The check engine light came on and the engine started making a "clicking" noise. I took the car to the mercedes dealership and they said that the balance shaft gear was completely deteriorated. They described the gear as "chewed up"! I had no choice but to pay $4,000. 00 to get the engine removed from my car and have the balance shaft replaced.
