Certain models of Mercedes-Benz can sometimes face serious mechanical troubles. A particularly common challenge with the Mercedes brand is gear selector issues, where the vehicle’s gear selector grinds, jerks, or even refuses to shift.
Below is important information about potential causes of gear selector failure, how you can find out if your Mercedes’ selector is failing, and what you should do if it is.
A variety of factors can cause problems with your Mercedes’ gear selector. The first and perhaps most common of these factors is natural wear and tear. Your car’s gear selector is part of its transmission, and as durable as your transmission may be, its gears and cables aren’t designed to last indefinitely.
Regular maintenance can help prevent your vehicle’s transmission from wearing out too quickly, but it will wear out eventually. This can cause huge issues with your gear selector, not to mention the rest of your vehicle, if not addressed in a timely manner.
Another potential cause of gear selector issues is valve body failure. In automatic transmissions, the valve body allows hydraulic transmission fluid to flow through the system, thus enabling easy gear shifting. If the valve body wears down or breaks, it can disrupt the flow of hydraulic transmission fluid, making gear shifting much more difficult. If this happens, the valve body will almost certainly need to be replaced.
Also, a broken or worn-down gear selector cable might cause issues with your vehicle’s gear selector. This cable (or cables, if your vehicle has manual transmission) connects your gear selector to the rest of its transmission, allowing the selector to change the gears. If the cable binds up, it will make it much more difficult for you to shift gears, and if the cable breaks, your vehicle will refuse to change gears entirely. Gear selector cable problems are more common in vehicles with manual transmissions, but can certainly happen with automatic transmissions as well.
A final common cause of gear selector problems in a Mercedes is manufacturing issues. Unfortunately, as sleek and well-made as Mercedes-Benz models typically are, they can still be susceptible to manufacturing errors, including a lack of transmission testing.
It is worth noting that transmission issues due to manufacturing errors are common enough in Mercedes-Benz models that some drivers have tried to sue the company over them. Therefore, if you have a Mercedes, you should pay close attention to the quality of your gear selector and your transmission overall.
There are several tried-and-true symptoms you can look for to determine if your Mercedes’ gear selector needs repairs.
Typically, the first signs that your gear selector may be failing are grinding or clicking noises when you shift gears. In addition, the selector may jerk or struggle when changing gears or refuse to shift from “drive” into “reverse.”
Less common but still significant, symptoms of gear selector issues may include the transmission failing to engage when you shift gears or your vehicle’s gear indicator needle being misaligned.
If you notice the above symptoms but do not respond to them quickly enough, your vehicle may soon develop more severe problems than a grinding gear selector. Because a faulty gear selector often indicates larger transmission problems, failing to address the above symptoms can sometimes lead to significant transmission issues, such as slipping from one gear to another.
Ultimately, a damaged transmission can completely destroy your vehicle’s ability to function. Therefore, if you notice early warning signs that your vehicle’s gear selector is failing, you should address the problem right away to save you the headache as well as expense.

Lexus has a reputation of quality and comfort. As an owner of one of its models, you want to maintain your vehicle so it performs as expected each time you take it for a drive. Engine issues may crop up with time and wear.
If you begin to experience engine problems with your Lexus, use this guide to help you diagnose issues and determine if your Lexus is in need of major inspections from a trained specialist to determine your engine issue.
If it’s your first time encountering engine issues in a Lexus, you may be wondering if it was user error or just inevitable wear and tear. Not to worry. All engines run into problems eventually. Just as your own body needs care and nourishment, so does your Lexus.
Routine maintenance and replacement of worn parts is natural. But before you bring your car to a shop and are forced to open up your wallet, you should have a general understanding of why your engine may be malfunctioning.
There are multiple signs and symptoms that could indicate problems originating from your engine. First and foremost, if your check engine light comes on, that would obviously point to a problem that needs attention.
Unfortunately, not all Lexus models have the more intelligent-engine monitoring, such as oil life monitoring systems. While that may be the case, there are still plenty of indicators that a look under the hood is needed:
One of the more visible signs of engine wear is the accumulation of oil beneath your car. If you are consistently seeing large wet spots underneath your car, your car will need service.
Knocking, grinding or rattling noises are good indicators that something is loose, damaged, or out of place. In addition, odd odors could also mean your engine needs help.
You may encounter dark grey or even blue smoke emitting from your exhaust pipe if your engine has not been maintained for some time. This could indicate a few problems, you may just need oil but there could be more severe damage.
If your engine makes a lot of noise each time you press on the accelerator yet fails to pick up the normal amount of speed, it’s likely your engine needs to be serviced as soon as possible. This could be dangerous for you and your passengers.
Smoke under the hood is another example of apparent engine problems. This particular symptom indicates immediate problems.You should pull over and call a tow truck to take your car to a repair shop. It is not safe to drive it at this point.
Identifying that there is a problem is an important first step, but diagnosing it may require a bit more knowledge. While most of us don’t have the time to learn all the ins and outs of Lexus engine maintenance, there are a few key things that are easy to notice:
Just as oil is a good first indicator of problems, it can also be a great test of engine integrity. Check your oil levels regularly, including pressure and cleanliness. Some problems can be remedied with surprising ease.
Another fluid that is a common cause of engine headaches when left unchecked is your radiator’s coolant. Coolant, often called antifreeze, is used to maintain your car engine’s prime operating temperature. Maintaining coolant levels is essential to your car’s health.
Keep an eye on all of your car’s various gauges, from tachometer all the way to odometer. These are there to specifically alert you to changes in the levels and warn you of any need for service or replacement of fluids.
Engines have a lot of parts, and each is as essential as the next. There are plenty of hoses and seals that have the potential to fail and cause major problems.
There are plenty of ways for you to investigate the engine problems for your specific model in its respective manual. If you’re having problems, flip though and it may end up saving you a buck.
