Questions to ask the seller
- Were recalls 23V858000 (fuel system, gasoline), 23V751000 (engine) and 19V060000 (fuel system, other) done? Ask for the dealer printout, or check the VIN.
- NHTSA has an open investigation into no restart after auto start/stop engages. Has this car had that problem?
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Any oil burning, leaks or check-engine lights? Ask for oil-change records.
- Do the brakes feel even, with no ABS or brake warning light? When were the pads and brake fluid last done?
- Acura sent dealers 146 repair notes for this car. Was this one done: “In a 9-speed a/t, the atf level is critical”?

How serious. Out of all 22 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 7K to 36K miles (12K to 58K km) on the car (19 of all 22 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
In owners' words
Vehicle was in motion on a highway in very heavy traffic when brakes were employed and vehicle did not stop but grinder forward, hitting the car in front.

Newest year first. Red = worse than average, gray = about average, too new (2023+: a partial score, marked “partial”) or too few complaints to score. #1, #2… = that year's YouTube rank among the 7 Acura TLX years with enough videos (#1 = the year owners and reviewers talk about most positively). It is not a reliability rank.
