Un intended non acceleration. Due to severe lag, delay, and sluggish transmission response. Acura has replaced my transmission under warranty at 11,000 miles and did not admit fault and say there was a problem. Here's more on my experience..in my 1 year of ownership.. to whom it may concern: 2016 Acura MDX 13,000 miles, purchase new from Sierra Acura, alhambra, ca I am writing to request buy back of my vehicle this car is a lemon. Since taking ownership a year ago, my 2016 MDX purchased new has experienced nothing but one problem after problem. Acura replaced transmission a month ago but the problem is still there. Is it engineered and designed to perform in a not safe manner " many times I experience shifting and accelerating hesitation and jerky/jolting. My family and I do not feel safe operating and riding in this vehicle. Several times gas pedal depressed and vehicle lagged at 20 mph for more than 10 seconds before accelerating. A few of the latest new and ongoing problems are below. Driver door now appears off set and at different angle protruding out now. Appears that the door is not closing properly and therefore not sealed at closing. Furthermore every single window has experienced faulty mechanisms with motors, actuators, and seals. When closing the doors it feels like the windows are loose. There are also squeaks and rattles eminating throughout the cabin area. I secured and collected all loose items and the sound is still there. At engine start up each time, there is a high pitch whining noise for a few seconds before engine starts (perhaps something else faulty") I have video / sound documentation of this with 2 seperate recording dates. With regard to the navigation, multimedia unit, it has been lagging, slow (er) to function, and severe delay in backup camera actuating, and audio functions delay in response sometimes.

Engine does not start and all the warning lights come up on dashboard. After a few seconds, each of the system comes up as failed. Dashboard shows as acc failed, lane warning failed, emission failed, engine check failed. This is a second failure in last 45 days. First failed on Nov 20 and car was in service till Dec 21. Again the engine failed on Jan 02, not allowing to start at all.

Nothing but trouble since I bought it. Purchased Jan 2016. Has replaced --- navigation, amplifier & fuel pump!!! owned 2016 MDX for less than a week- vehicle jolts forward-gives itself extra gas even when your foot is on the brake! transmission not smooth. Been in for service over 40 days now (total). Hesitates sometimes- was stuck at 15 mph for a few minutes. Radio goes unresponsive- no buttons work gets stuck at station/vol can't turn off either. Navigation died- turned off, then flickered(was replaced). Speakers went flat- amplifier died (was replaced). The engine idle feature doesn't work right. It doesn't keep my samsung phone charged. I've tried multiple cords including the original one that came with phone. Acuralink doesn't always work either. I sent a destination but it doesn't show up for a few hours or days! it tweets now. The window now squeaks (no, it is not tinted or anything). It makes a strange dripping noise when you turn it off. It eats gas! I fill it up and it's gone in a blink..not the appropriate miles. It beeps loudly and blinks that there is an object approaching for no reason- no one/thing there- nothing moving. It has a mind of it's own. I've been a loyal Honda/Acura owner for over 18 years and they have not helped. When they replaced the navi they said they'd give me $500 for my trouble- but didn't anyway. They say there is nothing wrong with it-- but just Monday said it needs a new fuel pump but is "so new" they don't have one so it had to be ordered. Disgraceful. I asked for it to be replaced- was denied. Acura client rep says- "at this time there is nothing we can do" I have a spinal condition and the jolting hurts me greatly. Somedays I can't drive my brand new vehicle bc I cant take the pain. They don't care. They don't stand behind their product either. Highly disappointed in vehicle and company
