Your vehicle's suspension system plays a crucial role in providing a smooth and stable ride. However, an aging suspension can develop issues that promptly need attention. At A-1 Automotive, we provide expert suspension repair in the greater Portland, OR area. Here’s a look at five warning signs of suspension trouble. Bumpy or Rough Ride One of the most obvious signs of suspension trouble is a noticeable change in the quality of your ride. If you start experiencing a bumpy or rough ride even on relatively smooth roads, it could indicate problems with your suspension system. Worn-out shocks or struts can no longer effectively absorb bumps and vibrations, leading to a harsher ride. Strange Noises Unusual noises coming from the suspension system may indicate problems such as worn-out bushings, ball joints, or shock absorbers. Listen for clunking, squeaking, or knocking sounds, especially when going over bumps. These noises typically worsen over time and should not be ignored, as they often signal underlying problems that require attention. Uneven Tire Wear Uneven tire wear patterns, such as excessive wear on the inside or outside edges, could indicate suspension issues. When the suspension system is not functioning properly, it puts uneven pressure on the tires, causing them to wear out unevenly. This can compromise traction and handling. Persistent Bouncing After Bumps After hitting a bump or pothole, your vehicle should quickly settle back to its normal position. However, if it continues to bounce excessively, it's a sign that the shocks or struts are worn out. Visible Damage or Leaks You’ll want to promptly alert the mechanic if you notice any visible damage, such as bent or broken parts, leaking shock absorbers or struts, or worn-out bushings. Any signs of physical damage or fluid leaks indicate potential issues that need to be addressed ASAP. Ignoring such problems can lead to further damage and safety hazards.

A faulty alternator can cause your battery’s power reserve to become exhausted to the point that your car won’t start. By getting to the shop at the first indication of an alternator issue, you’ll have the best chance to avoid ending up stranded and needing assistance. At A-1 Automotive, we provide expert alternator replacement and auto electric repair in the greater Portland, OR area. Here are five common signs of alternator trouble. Dimming or Flickering Lights If you notice your headlights, interior lights, or dashboard lights behaving erratically, it could be a sign of an underlying alternator issue. Since the alternator powers these electrical components, fluctuations in their brightness often signal a problem with its ability to maintain a consistent charge. Warning Light Commonly depicted as a battery icon, this light illuminates when the alternator isn't generating sufficient power to keep the battery charged. If you see this light come on, don't ignore it. Ignoring it could lead to a dead battery and an inoperable vehicle. Strange Sounds Unusual noises arising from your engine can indicate various issues, including alternator trouble. A common sound associated with alternator problems is a grinding or whining noise, which may suggest worn-out bearings or a malfunctioning belt. Difficulty Starting the Engine The alternator replenishes the battery's charge while the engine is running, so if it's malfunctioning, the battery might not have enough power to start the engine. If you experience difficulty starting your vehicle, it's worth having both the battery and alternator checked. Electrical Accessory Malfunctions Since the alternator powers various electrical components in your car, malfunctions in these systems can indicate alternator trouble. For example, if your power windows operate sluggishly or if your radio and air conditioning system intermittently cut out, it could be due to a failing alternator.

A car that refuses to start can be a frustrating experience, especially when you're in a hurry. In many cases, a car will show signs of struggling to start before it fails to start altogether. In such situations, it’s important to get to the shop to address the issue before it escalates and leaves you stranded and in a difficult situation. At A-1 Automotive, our local mechanics are experts at identifying and fixing issues that cause no-start. Here are five common reasons that vehicles fail to start up. Dead Battery One of the most common reasons for a car not starting is a dead battery. This can happen due to leaving lights on, a faulty alternator, or a battery that has reached the end of its lifespan. Faulty Starter Motor A malfunctioning starter motor can prevent your car from cranking. Signs of a faulty starter include a clicking noise when turning the key. Fuel System Problems Issues within the fuel system, such as a clogged fuel filter or a faulty fuel pump, can lead to starting problems. Fuel system issues commonly cause problems such as sputtering and decreasing gas mileage. If your car cranks but doesn't start, consider checking the fuel delivery system. A professional inspection may be needed to identify and fix the specific problem. Faulty Alternator The alternator charges the battery while the car is running. If it fails, the battery can't maintain a charge, leading to a no-start situation. Signs of a faulty alternator include dimming/flickering headlights and malfunctioning interior electrical accessories. Ignition System Issues Problems with the ignition system, such as a failed spark plug or a faulty ignition coil, can hinder the combustion process. If your engine cranks but doesn't start, faulty spark plugs or other ignition components could be the reason.
