Two days after getting our first oil change. The car wouldn't start in our garage. The system flashed on and off rapidly. A tech came out and jump started the engine manually because the computer wouldn't start it. I drove it to a second Acura dealership and they stated that the onboard computer randomly sought out a system update so it impacted the engine. I asked what caused this on a new 2016 MDX and they couldn't explain it nor could they promise it wouldn't happen again. If they couldn't predict when the computer does this, then what's to stop it from doing this while the car is in motion? this is a safety issue that needs to be investigated. Thank you.

This is almost brand new 2016 Acura MDX AWD (with tech and entertainment packages). When accelerating on a freeway/road, suddenly lots of the warning lights turn on and then the vehicle does not accelerate any more. The speed suddenly drops. This is definitely a hazard - especially because I am trying to accelerate. This happened 4 times so far - roughly 500 miles between each incidents. The problem condition goes away after we completely stop the vehicle and turn it off and on multiple times (and also put the vehicle in neutral in between). Last time when the problem happened, I cleared the condition and then drove and showed the vehicle to the dealer. The dealer said that there were persistent codes about communication failure and he cleared them. And asked us to call back when the problem happened again. Dealer does not seem to know any systematic problems with such types of vehicle. I have a video of the previous problem condition at https://youtu.be/ljslicwj7-8

Very similar to NHTSA id number: 10762375. After 3-4 days of driving the check engine light came on along with transmission system U0401, vsa problem, hill start assist problem etc etc etc. The SUV would not speed above 35-40 miles and shake. Dealership replaced cracked spark plug, ignition coil - cause - possible moisture in spark plug. They were nice enough to take the car back and currently waiting for it to be replaced.

On 9/3/15, I was pulling into my garage when all the warning lights on the dashboard went off - transmission, check engine, lane detection light etc. Since I was going out of town the next morning, I put it in reverse and drove directly to the dealer. The car was in "limp mode" and I could only drive 35-40 mph. I showed the tech in the service dept. All the warning lights going off, and he said he had never seen anything like this before. He wrote up a work order with the following info: Inspect for check engine light on, check engine light flashing and every warning light in the vehicle is on, would not accelerate over 35 mph. The following day I was contacted by the service dept. And was told they could not find a problem; there were no lights on, they even drove it for 40 miles. The service dept. Said they are only allowed to hold the car for five days. Today, 9/8/25 I picked up the car. The dealer's invoice reads: Cause: Light on 123505 diagnostic trouble codes/programmed fuel injection (pgm-fi) retrieve codes with the hds, read data, 74 WA3. Inspected for check engine light on, found dtc P0303 (cylinder # 3 misfire) recorded freeze data and cleared codes, at time of inspection vehicle was running perfectly, test drove vehicle twice on extended test drives and engine ran perfectly, no dtcs are reset no problem is present at this time. Since the service dept. Could not find the problem and fix it, this means the car has not been repaired and I am driving a defective car. The next time the warning lights go on, I could be travelling on a crowded freeway at a high rate of speed (with my family inside), the car goes in to "limp mode - 35 mph and an accident occurs. This is a safety issue. How can Acura manufacture a $50,000 car and their dealership not be able to find the problem and repair it?
