We, the undersigned, represent a group of owners who purchased the all-new Acura TLX in 2015 and are seeking action from Acura to remedy poor transmission performance.

The ZF 9HP 9 speed automatic transmission used in the TLX application has exhibited hard shifts, slow engagement, among other undesirable behavior not consistent with a $40,000.00 sport luxury product.

The slow engagement has concerned many, as it has been found to be a safety issue when merging into freeway traffic, turning onto a busy street, or any time you require somewhat quick acceleration. There can be upwards of a 2-3 second delay before any power kicks in.

The hard shifts usually occur between the second to third gear upshift resulting in a jolt in contrast to other shifts which are smooth and nearly imperceptible. These hard shifts are disruptive, noticeable to passengers, and embarrassing when transporting others in the car. Acura has made attempts at fixing the issue in the TLX with two technical service bulletins specifying software updates. Many have found these updates do not fix the problem. It should also be noted that the new Acura MDX, which uses the same transmission, does not suffer from this issue.

We collectively demand that Acura immediately take whatever action is necessary to correct the problem many unsatisfied and loyal customers are having.

Thank you for reading, and thank you for your support.
