2018 Mercedes-Benz GLA250 4Matic First Test: Fun, But Far From Perfect

  2018 Mercedes-Benz GLA250 4Matic First Test: Fun, But Far From Perfect Let’s face it: Subcompact crossovers aren’t known for their blistering acceleration or high-grade interiors. In fact, some can be quite slow and quite Spartan. From the Toyota C-HR we’ve clocked hitting 60 mph in 10.8 seconds to the well-worn cabin of our recent long-term Mazda CX-3, there’s often at least one quality that makes a subcompact crossover feel a little less polished than other vehicles. That's what happens when automakers try to keep costs low. Generally, premium offerings fare better, and the Mercedes-Benz GLA250 is no exception.

So, here we look at what should be done to fix the problem, and how you can claim compensation if your car is damaged by a shoddy road. So it's important that you report potholes to your local authority because it will then have to fix them.

My tips on what you need to know if you hit a pothole , and whether you should claim on your insurance.

There’s no upside to encountering potholes. Brought on in droves as the freeze/thaw cycle weakens and breaks up road surfaces, they become enlarged as each passing vehicle pounds into them and furthers the destruction. In the fluctuating weather that often occurs at this time of year in much of Canada, they’re an unfortunate reality.

The T-Roc is a lovely compact SUV, one size down from the Tiguan and so stylish it can be bought in dozens of different colour combinations. There are six different engines available here in Europe, three gasoline and three diesel, and it’s available in either front-wheel drive or all-wheel drive.

In the most severe cases, driving over a pothole could lead a driver to lose control of their vehicle. The damage done to a car ’s key components by hitting a pothole or a large number of potholes over time will need fixing at a service garage. What do I do if a pothole damages my car ?

Inevitably, you will drive through one. Probably many. Possibly stretches of road that seem to be made of brief sections of pavement interspersed amongst a lunar surface of broken asphalt and water-filled holes of unknown depth and size. They’re largely unavoidable, virtually inescapable, and they have the potential to damage your vehicle and cost you money.*

*Note that while many cities and municipalities have policies in place to compensate motorists for pothole damage, the process can be tedious, the onus falls on the driver to prove the damage was caused by negligence on the part of whomever is responsible to maintain the road, and – based on the City of Toronto’s standards, anyway – the size that the pothole must be before it is even considered an issue may prove surprising. Check out Table 1 in Section 6 of the relevant part of the city of Toronto Act: the minimum size for a pothole to be considered an issue is 8 cm deep, or 600 square cm in surface area. That’s big.

ABOVE: There’s been a recent spike in cars damaged by potholes . Mark McAllister reports. TORONTO – We’ve all been there – merrily driving along when all of a sudden, it sounds like your tire fell off. You’ve hit a pothole .

Potholes are more than just an annoyance, they can cause a lot of damage to your car . Potholes are those craters in the road that form when cracks in the asphalt are widened by water, ice and salt, then freeze and expand to push out the dirt and gravel, leaving a hole .

How the Damage Occurs

The damage caused by driving through a pothole begins at the tire, as it’s what first impacts the far side of the pothole. Crushed between the edge of the road surface and the wheel of the vehicle, it gets subjected to violent and very concentrated forces. Modern tires are surprisingly robust, however it is very possible for the sidewall to get pinched between the wheel flange and the ground. The result can be a puncture, a deep sidewall slice that compromises the integrity of the tire, or even cut belts within the structure of the tire. Tires are by far the most likely part of your car to fall victim to a pothole.

The wheel is next in line. Bent lips, fractures/cracks, or even being bent out of round or out of parallel are all possibilities. Some of this damage may not be obvious without spinning it in place on a hoist or mounted on a tire balancer.

While some stick ink-filled needles into their bodies, others poke holes in all sorts of places. There are even some folks who actually wear white after Labour Day. Shocking, I know, but it’s true.

Are potholes giving you an expensive repair bill? Fear not, as you might be able to claim compensation. Potholes are a nightmare, this we know. You can’t drive five minutes down the road without becoming intimately acquainted with at least one of them.

Typical Pothole Damage. Billions of dollars of damage certainly sound steep, but what does that really equate to in a daily driver’s life? The easiest way to avoid potholes is by keeping your distance from the car in front. Tailgating cars will obstruct your view of potential potholes .

The wheel bearing experiences the impact shock from the wheel at the same instant as the wheel. Direct bearing failure as a result of hitting a pothole is extremely unlikely; however, repetitive or severe impacts can crater or flake the chromed surfaces in which the bearing’s balls or rollers run on, leading to premature death, excessive play, or – quite commonly – noisy operation.

Immediate injury to a shock or strut from an impact is similarly unusual, though their mounting points can break in extreme cases. Even so, every motion of the suspension is countered by resistance from those components, which pass oil through tiny holes and valves to create that resistance, a process that generates heat. Besides the expected physical wear, tremendously rough surfaces taken at speed, such as a dirt road or heavily pockmarked highway, can actually overheat the shocks, potentially damaging the seals, eventually leading to oil loss and damping failure. An oily damper is a failed damper, and it and its matching mate should be replaced.

There are a multitude of different suspension layouts, but there’s some commonality between them – all use some kind of bushing or pivot where they connect to the vehicle’s frame or body; all use some form of ball joint, strut mount, or kingpin to facilitate steering; and all can suffer from bent, fractured, broken, or worn out components and mounting points. Regular vehicle inspections are a must, and any unusual behaviour – especially in the wake of a particularly noteworthy impact – should be investigated as soon as possible. The pounding that your average ball joint or tie-rod end receives is astonishing, and in most cases failure will lead – at minimum – to considerable damage to the vehicle and the need to be towed, with the very real possibility existing of a loss of control leading to a serious crash.

SUV Review: 2017 Land Rover Discovery V6 HSE Luxury

  SUV Review: 2017 Land Rover Discovery V6 HSE Luxury Luxury off-roader is improved on from before, and the V6 gives scoot if not decent fuel economyThe fifth-generation Discovery, which debuted earlier last year, is decidedly better looking and more luxuriously contented than before. One of the hallmarks of the four previous generations was the stepped roofline, allowing for greater headroom in the available third row of seats. Though not as perceptible as before, it remains a key design cue. Far more noticeable is that the squared-off profiles of past have given way to a more streamlined design, ensuring the newest Discovery —muscular, masculine — is the most aerodynamic version yet, its drag coefficient of 0.

Share Tweet Pin. Think driving will get easier once the winter season ends? Think again. Warm spring weather melts away slippery snow and ice, but it also brings out one of the most problematic elements on the road: potholes .

Potholes are likely to appear in winter and spring when ice and running water disrupt the soil layer beneath the road surface. Cars driving over these weak spots in the road cause the top layer to deform, crack and chip away.

Warning Signs of Damage

There are immediate signs to watch for after running into a particularly memorable pothole, especially those encountered at any kind of meaningful speed. Most of the same symptoms also apply to damage caused by skidding or sliding into a curb, ditch, or snowbank, whether there is visible harm or not.

Signs of immediate concern include a shimmy felt in the steering wheel or through the vehicle body that was not present beforehand (often most noticeable at low speed), pulling, a misaligned steering wheel (i.e. crooked when driving straight ahead), or any unusual rattling, clunking, or rubbing noises.

If you observe any of these symptoms, particularly after hitting a pothole, road heave, or suffering an inadvertent impact, you should have your vehicle inspected by a qualified repair shop.

Impacts severe enough to damage a tire or wheel can also damage other less visible components within the steering and suspension systems, so the same advice applies even if a flat tire is the only apparent consequence of your incident.

Minimizing the Consequence

There are lots of factors that influence how much (if any) damage potholes or heavily broken pavement will cause. Obviously increased speed means increased impact energy, but the low-profile tires used on high-end and sporty cars are at greater risk than the taller tires common to trucks and many SUVs.

What do you need? Car insurance. Hitting one at a higher speed can cause a lot more damage to your car . You could also lose control and end up crashing, So, if you’re unlucky enough to hit a pothole , here’s what you need to do

David Rogers, the Monday Morning Mechanic, shows what kind of damage that potholes can do to your car , and explains why having your can inspected

A recommendation that I make to my customers is the use of a dedicated set of wheels for their winter tires, using a smaller-diameter wheel whenever that option exists; this applies to both cars and light trucks. (Keeping the overall diameter of the tire as close to the original as possible by selecting an appropriate replacement size will maintain speedometer accuracy, clearances, and gearing.)

Smaller wheels mean using (often less expensive) tires with taller sidewalls – more forgiving of impacts – while relatively inexpensive steel or aftermarket alloy wheels minimize the cost of replacement in the event damage does occur. Less expensive at changeover time and eliminating the potential for damage to both tire and wheel during mounting and dismounting, a second set of wheels offers an additional bonus: keeping the original (usually ludicrously expensive) factory wheels away from both prime pothole season and the corrosive effects of salt and anti-icing brine.

In this part of the world, it’s unlikely that you’ll be able to avoid every pothole, but there are ways to reduce their impact on your car and your wallet. Recognising the signs of damage if it should happen can still allow you to minimize the risk of further harm to your vehicle and safety. The pavement should be the only thing that gets all broken up about pothole season.
