Some Common Problems
The 2008 Acura TL Type S has an engine with a displacement of 3.5 liters, producing 290 horsepower and 267 foot-pounds of torque. The car is equipped with a five-speed automatic transmission which sends power to the front wheels. When launched, this vehicle had the distinction of being the most powerful front-wheel-drive car available on the market, which led to some extreme acceleration. However, it has come under criticism for its durability and powertrain problems which include:
1. Engine shuddering
Acura Tl Type S - 2008 Shuddering Issue This vehicle is equipped with a V-TEC (Variable Valve Timing and Lift Electronic Control) introduced in 2007 with the 3.7-liter V-6 engine design seen in other Honda products such as the Acura RL. In this system, the intake valves open and close at a different time than traditional V-6 engines, increasing engine performance. Acura's V-TEC is also supposed to have a smooth acceleration from idle speeds. However, there have been many reported cases of an engine shudder when accelerating or decelerating. Most of these reports center around the city where stop-and-go traffic loads the car's powertrain. When owners take their vehicles in for service, they are often told that the problem lies with their driving habits, and it usually goes away after a while without any intervention from Honda. Other owners, however, continue to experience issues, especially when driving in stop-and-go conditions.Engine Shuddering Solution: - The first remedy is to change the engine oil every five thousand miles for high-mileage cars. This should help resolve some of the problems caused by excessive oil consumption which are typically due to worn valve seals. - The second solution is to install a can of MAF t cleaner into the intake manifold, then run the engine until it stalls so that all of the cleaner gets sucked in. Some people recommend sprinkling baby powder or talcum power on top of each spark plug before running this treatment so that any excess cleaner does not further damage your car's electrical system.
2. Transmission stalling
Some owners have reported that the transmission would shift to neutral when accelerating, which leads to stalling. The dealer can reset the computer which should take care of this issue. However, if you do not want to take your car in for service, many members on ClubTL.com suggest turning off the 'shift lock' feature whenever this problem arises, so that you will be able to shift back into drive or reverse manually.
3. Transmission slipping
This occurs when there is too much load on the engine while it tries to accelerate, such as while trying to move uphill. Owners report having fixed this issue by downshifting so that less power is needed from the engine. Another involves holding down the accelerator pedal to the floor while shifting, which is not recommended by Honda.
4. Excessive oil consumption
Engine Oil Consumption Since 2007, many owners have reported that their V-TEC engines are consuming excessive amounts of oil. Some people claim that this is due to inferior manufacturing of the engine, while others say that it merely falls in line with how all Honda automobiles consume oil over time. Many owners note that they fill up their cars with a half quart of oil every 1,000 miles after initially changing it every 3,000 miles when new.
5. Clogged fuel injectors
This problem involves incomplete combustion which leads to carbonaceous deposits on the intake valves and therefore requires cleaning by removing the manifold from the vehicle and soaking the valves overnight in an appropriate solvent. Although this should be done by a professional mechanic, you can find DIY instructions on ClubTL.com by doing a search on the forums.
6. Loose wire harnesses
This issue involves the connection to the car's anti-theft system, which can cause all of the doors, windows and even the trunk to unlock when running any electrical accessories such as the radio or air conditioning system. This is not an issue for most owners, but it can be irritating nevertheless.
7. Faulty PCM (powertrain control module)
The powertrain control module manages engine functions including idle speed, fuel injection timing and torque converter lockup. Faulty wiring or loose connections have been known to cause this problem according to some owners who have found service bulletins detailing similar issues on other Honda models such as Civic and Accord.
8. Faulty engine mounts
The engine mounts cushion the engine from vibration caused by torque from high-revving engines such as the VTEC V6 found in the TL, and should therefore be replaced when they wear out or break. Many owners have also reported issues with their drivetrain -- specifically, an issue where a rattle develops near 3,000 RPMs typically after changing the transmission fluid. While there have been claims that this noise is due to faulty flywheel bolts or a worn throwout bearing, many people insist that it is merely a problem with the car's exhaust system which can be alleviated by removing one of the small resonator boxes located behind each muffler near the catalytic converter.
9. Worn out timing belt
The timing belt is responsible for synchronizing the camshaft and crankshaft rotation that ultimately allows your car to run. The engine's valve timing must be set correctly to prevent any issues with compression, which will lead to problems such as stalling, poor acceleration and reduced gas mileage. A worn out timing belt can cause all of these problems and more, which is why you should always keep it in good condition.
10. Transmission jerking
This occurs when the car is put into drive or reverse abruptly after being rolled to a stop. According to some owners, this problem can be easily remedied by rolling forward slightly before putting the transmission in gear. The issue may become worse over time, however, so it's best to have your transmission looked at if you experience any problems.
11. Transmission failure
Many owners of Acura TL Type-S models with 6-speed manual transmissions have experienced shifting problems that ultimately lead to total failure of the car's transmission. This is due to defective synchros according to some owners who claim that the company has refused to do anything about this issue despite knowing about it for several years. These people may not be telling the truth however, as there are many people out there with no issues whatsoever. Be aware though that in certain cases when the synchros fail completely, drivers can shift gears but they will not know which gear is selected until after accelerating when their power meter displays the correct gear.
12. Rear differential failure
This issue occurs when the rear differential seizes and causes all power to be transmitted to one wheel instead of both wheels equally. It typically happens gradually enough for owners to notice it but it can occur very quickly in some instances such as driving on gravel or snow. If you suspect that you might have this problem, try driving up a clean dry surface such as asphalt or concrete and see if your car pulls to one side while accelerating from a stop.
13. Faulty camshaft phaser
Faulty phasers cause the engine's timing to go out of sync which prevents it from running correctly and may also result in major damage due to valve and piston interference with each other in some cases. In other instances, however, it can cause a loud ticking sound or knocking that occurs when the car is being driven at high speeds for an extended period of time.
14. Misfiring spark plugs
According to some owners who have experienced this problem, the metal part in the center of the spark plug called a "center electrode" erodes much faster than normal. When this happens, the air/fuel mixture begins to misfire which causes rough idling and acceleration problems until it completely fails to start up. This issue may also result in codes P0300-P0304 which indicate random misfires in one, two or three cylinders that typically do not affect your car's ability to run for very long before going out entirely.
15. Faulty turbocharger wastegate actuator
This component regulates the amount of boost provided by the car's turbocharger which is necessary to maintain its maximum power output at all times. A faulty wastegate actuator can cause several different problems, including slow or weak acceleration, louder than normal turbocharger whine and reduced fuel economy. Surprisingly enough, however, it's something that many owners never have any issues with whatsoever.
The Acura TL is a pretty good car overall but it's not perfect by any means. There are numerous issues with this vehicle that seem to be more common than with other vehicles, especially when you consider the fact that it's a luxury car and not an economy or sports car. Many of these issues can be easily remedied however and most people never experience any problems whatsoever. If you're looking for a new car and you're considering this one, we highly recommend checking out consumer reviews online before making a final decision. If you know someone who owns one of these vehicles, ask them about problems they had and how they resolved them. It definitely helps to hear first-hand experiences from an owner instead of relying on reviews that were probably written by people who don't even own the car in question.You may be interested in a 2002 Acura Rsx Engine for sale
