Headlights somehow may be taking on moisture. The clarity is down to almost nothing. Driving at night is unsafe! The RPM’s have never been smooth or consistent. There is almost a micro-revving effect. I’ve had all of the fluids and filters changed…… dealership thought it was a recall.

On or about 50,000 miles we noticed the car would surge when driving on a flat level surface about 50 miles an hour. The tachometer will show a pulsing RPM my wife first complaint officially about it when the car head just over 80,000 miles and we were told it was a software issue but it was out of warranty.. This does not seem like it should be expired as it is an issue with the car and should be a relatively easy fix and not have to pay $400 to have it done

First, I have had the vehicle for a little over a year. I have driven to florida and nc without issue. Today will be the 4th time taking my car to the acura dealership in less than 3 months. Today the car started to kickback when I reach 20mph. Also, at 80mph the car is jerky when I accelerate or decrease and go again. Also when I release the gas, the speed decreases quickly as opposed to gradually. Around 60mph the car tends to have a slight jerk which ive notified acura but they said I need a wheel alignment which ive done. The issue prior was all the lights in the dash came on the the drive function was almost paused while the vehicle was in motion. Acura claimed the issue was minor yet I am going again today. Prior to that issue, something near the tires was scratching or something which they claimed the issue was fixed. What LED me to the dealership the first time was the vehicle was jerky at different times while accelerating. Acura performed a software upgrade which fixed the issue for a couple days. At some point, the vehicle needs to be re-assessed and possibly totaled out or something. I have 3 kids and always on the run. I used to trust acura and the reliability but the issues seem to get worse and worse.
