When it comes to car shopping, it’s essential to do your research and consider all factors before making a purchase. One crucial factor to consider is the reliability and potential issues of the car you’re interested in. Acura is a popular brand known for its luxury and performance. However, like any car, it’s not immune to concerns. We’ll discuss three of the most common Acura issues you might want to consider before car shopping.

1. Check engine and D4 lights flashing is one of the most common Acura problems

One of the most common concerns that Acura owners might encounter is the check engine and D4 light flashing issue. According to RepairPal, 353 people have reported this problem, with an average mileage of 132,057 for the Acura TL and 120,138 for the Acura MDX.

This issue affects 17 model years from 1996 to 2014 for the Acura TL. The problem with the check engine and D4 flashing lights is usually caused by a faulty transmission control module (TCM) or a bad torque converter. The TCM is responsible for managing the transmission’s electronic systems and shifting patterns, and when it malfunctions, it can cause the check engine and D4 lights to illuminate. A bad torque converter, on the other hand, can cause transmission slippage, resulting in flashing lights.

This issue affects 17 model years from 2001 to 2017 for the Acura MDX. The cause of the check engine and D4 flashing lights is the same as for the Acura TL: a faulty TCM or a bad torque converter. However, the Acura MDX also requires a transmission fluid change that costs between $115 and $132, and the check engine light diagnosis and testing, which costs between $110 and $139.

2. Shudder or vibration while driving at speeds between 35 and 40 mph

Over 220 people have reported this issue, with an average mileage of 116,773. The problem impacts Acura MDX’s 15 model years from 2001 to 2017. This issue is often related to a problem with the torque converter or transmission mounts. The shudder or vibration is usually felt when the vehicle shifts between gears or when the torque converter clutch engages or disengages. If left untreated, the problem can cause further damage to the transmission, leading to costly repairs.

A general diagnosis by a certified Acura technician is necessary to determine the root cause of the shudder or vibration. The cost of a diagnosis typically ranges from $110 to $139. Depending on the severity of the problem, the solution could be as simple as changing the transmission fluid or replacing the transmission mount. However, in some cases, a transmission overhaul or replacement may be required, which can cost thousands of dollars.

3. Sensor problems may cause the SRS light to turn on

The SRS (Supplemental Restraint System) light is an important safety feature designed to alert drivers if there is a problem with the airbag system in their Acura RL. When this light turns on, it could indicate a problem with the SRS system, such as a malfunctioning sensor. Over 150 Acura RL owners have reported this problem.

The affected vehicles for this problem include the 1998 to 2007 and 2012 model years. The average mileage for Acura RLs experiencing this issue is 132,336. Acura RL owners can expect to pay a general diagnosis fee of $110 to $139 to diagnose and fix this issue. It is essential to address this issue as soon as possible, as a malfunctioning SRS system could potentially cause serious injury or death in the event of an accident.

If the SRS warning light on your Acura RL comes on, it’s essential to take your vehicle to a qualified mechanic to diagnose and repair it. The mechanic will use specialized diagnostic tools to identify the exact cause of the issue and provide an estimate for the repair.
