2020 ACURA TLX — Complaint #1917351
Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL filed August 9, 2023
NHTSA complaint #1917351 (ODI reference 11537350) concerns a 2020 ACURA TLX and was filed on August 9, 2023. The owner reports the failure occurred on August 9, 2023. The report was geocoded to Massachusetts based on the filer's self-reported location. The affected component is categorized as engine and engine cooling:exhaust system:emission control, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same ACURA TLX cohort independently describe similar engine and engine cooling:exhaust system:emission control failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2020 ACURA TLX shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
I purchased a new Acura TLX in 2020. The following year it took it into get state inspected in Massachusetts. My care failed for emission 3 times. I brought it back to the dealer (Herb Connolly) in Framingham Massachusetts. They kept it for 3 weeks, worked on it and told me it was all set. The following year I brought it in for a state inspection. The same thing happened. They told me that they had seen a few of these cases. They found a way to get them to pass. They have to drive it at different speeds for a few hundred miles. I asked that they fix in properly and they noted that they did not have a fix. This was all after I picked it up. I told them I was concerned as I worried this could keep happening. They encouraged me to call Honda Motor Corp. I spoke to them several times and they denied the problem. I am not in my third year. Car is still under warranty and it again failed inspection. Below is an email from the service manager on how to get it to pass. From: M
