Transmission shudders at various speeds between 15-55 mph. most severe at approx 35-40 mph between 1500-2000 rpm. this is a known issue by acura/american honda as evidenced by service bulletin 16-044.
While driving my car my rpms fluctuate and my car can't seem to get into gear. it is all over the place and very scary at times. it seems to be something with the transmission and also a very common problem. this should not be the consumers problem. acura should be living up to there name by fixing this problem. acuras should never have a transmission problem. thats why my husband and i are loyal customers. i am very disappointing.
Rpm's fluctuate on the tachometer while accelerating. they jump up and down and you can feel the vehicle hesitate. based on what i am reading, this appears to be a well known issue with programming and with the torque converter that can result in transmission damage. even if the torque converter is replaced, which is an expensive repair, this appears to be a re-occurring issue. our 2012 mdx has 79,365 miles on it which is just outside the power train warranty and well before a transmission should be going on an acura vehicle. this started happening a couple months ago and now is a daily occurrence. being this happens at any speeds and while moving and is directly tied to the computer, this could lead to failure on a busy road and a potentially dangerous situation. being a common issue that is well documented, i feel this should be covered by warranty and fixed by the manufacturer.
Vehicle has been lunging at steady rpm of 1.6. when taken to dealership they said there was a service bulletin indicating early degradation of transmission fluid caused by software issue was causing the issue. would not cover the repairs under warranty. tsa 16-044 issued in november of 2016. car was under warranty when acura became aware of issue and did not notify consumers of issue. have spent numerous phone calls with acura and the dealership and they cannot provide a date when software update will be available to fix the issue. temporary solution was to change transmission fluid, which i had to pay for. acura cannot tell me of permanent damage to transmission due to known issue with software causing early decay of transmission fluid.
My 2012 mdx suffers from a torque converter rumbling sound and vibration common to the mdx series. as you accelerate the noise and vibration can be felt almost like a bearing noise which will eventually cause a lockup or failure possibly resulting in injuries to any drivers or pedestrians. the dealers are saying that this noise is indigenous to the inherent history of the vehicle . fact: so i'm not alone in this and i know any vibrations in that area will definitely lessen the life of the vehicle and cost the car owners ! god forbid ! there refusal to simply replace the converter is a refusal to sell good vehicles and this should be a recall asap ! updated 10/22/13 acura client services informed the consumer was informed that all the mdx vehicles near the same year, have an inherent documented knock on acceleration regardless of what premium fuel is used.
