general problems of the 2012 Acura MDX

Shuddering when going between 20-40 miles.

Ever since I bought the car I try to take it back to get it was because the car rpm fluctuate about 1500-2500 rpm range and 30-40mph causes the car to jerks like its trying to go and braking at the same time. It does this consistently in city streets sometimes it does that on the highway. Especially going up hills. I just don't feel safe at all when the car acts up like that. I take it back to where I bought it from they keep saying is normal I even took it to Acura dealer and the technician says its normal and that I need to press on gas harder. This is bullsh*t.

The transmission broke even after the regular maintenance. Spent more than $5,000 with the dealer to fix it.

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.

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.

The engine consistently consumes too much oil between service events. The low oil light comes on. I had this problem for over 8 years and the dealership said it was not a problem until now and they want me to pay for it. The oil control rings have been clogged since 2016 and progressively gotten worse. The clogged rings cause restriction of oil to return to the crankcase. This causes a decrease in available oil and may cause overheating that could lead to engine fire. Acura should fix the oil control rings to function properly. They have identified this in the past, through a service bulletin (19-006). I have performed 97% of my oil changes at Acura dealerships.
