5/5 Overall
NHTSA 5-Star Safety Rating
Complaints about the 2020 TLX center heavily on engine and fuel system issues, with drivetrain problems making up a third significant thread. On the engine side, owners frequently report internal failures, spun rod bearings and connecting rod bearing damage are mentioned across multiple reports, in some cases occurring even after prior engine work. The fuel system complaints, while numerous, overlap with engine and emissions-related warning lights that owners describe coming on without a clear diagnosis, including the parking brake warning illuminating unexpectedly. Powertrain complaints describe transmission behavior including harsh or delayed gear engagement, uncommanded shifts to neutral during acceleration, and situations where the transmission would not respond without manually forcing a gear change at high engine speed. A recurring front camera failure affecting adaptive cruise, lane assist, and automatic emergency braking also appears across multiple reports, with owners noting the system stops functioning well before high mileage.

With Injuries
By System
The 2020 Acura TLX has 5 recalls, the most serious being a passenger seat sensor that can misread occupant weight and cause the front passenger airbag to deploy incorrectly in a crash, raising the risk of injury.
On the engine side, a connecting rod bearing can wear and seize, causing the engine to run roughly or stall while driving, with a risk of fire or a crash. The fuel pump can also fail and stall the engine while moving; prior repair attempts did not fully resolve this issue, which is why it appears across more than one recall here. Together, the engine and fuel pump concerns mean a stall while driving is a notable risk for this vehicle.
