Car insurance looks to ditch pink slips, but it’s not as easy as it sounds

  Car insurance looks to ditch pink slips, but it’s not as easy as it sounds Survey shows most Canadians want it on their phones, but there are still a few regulatory hurdles to jumpThey are if consumers have anything to say about it. Like rotary phones and letters in the mail, the inconvenient tiny documents are often misplaced, expired or forgotten after their annual glovebox shuffle. A new survey from the Insurance Bureau of Canada (IBC) asked Ontarians what they’d like to see insurance companies institute in the future.

Today, ECUs control or finely tune a wide array of critical functions, including steering, acceleration, braking, and dashboard displays. "The fact that a risk of attack exists but there is not a way for researchers to monitor or interact with the system is distressing.

We recently covered the risks that come with certain modifications and upgrades, but left out one key area until now – plug-in computer chips for certain vehicles that can accommodate certain changes. For instance, you can purchase certain chips for many popular SUVs and pickup trucks that keep systems running correctly when oversized tires or off-road axle gears are installed. The software will interact with various on-board systems to correct wheel and vehicle speed calculations, available Most are available through off-road equipment specialty shops for pricing and ordering.

The risks of tampering with your car ’ s ECU . Plug-and-play ECU mods are an easy way to make good power, but there are a few risks to consider.

Here is how to reset your car ' s ECU to get better fuel economy and/or for your car to lean how to use new upgrades.

While we’re on the topic of plug-and-play chips, it’s worth mentioning a few things about these performance-enhancing modifications. These have been around since the beginning of computer-controlled fuel injection and they’re popular with enthusiasts who look for better-than-stock performance.

On gasoline engines, they can advance ignition timing and adjust fuel injection rates, among other things. For diesels, they can boost injection rates putting more fuel into the recipe. For responsible drivers who look after their rides, these can be helpful additions and won’t usually present any problems. But there are some risks to consider.

First, all automakers have clauses in their warranties that indicate that any damage or problem that can be directly attributed to the installation and use of aftermarket products will not be covered. For many accessories, this is fairly straightforward. You’re not likely going to be denied a warranty request for a defective water pump, just because you installed a lift-kit on your truck. Similarly, your wallet should be safe if a steering rack failed on a vehicle with aftermarket trailer hitch wiring. But engine controllers and computers touch pretty much almost every system on a vehicle, so when you add some unauthorized software to these electronic brains, you may risk a lot of warranty coverage.

Warranty Killers on New and Used Vehicles

  Warranty Killers on New and Used Vehicles Nobody likes unpleasant surprises, especially when they cost you a lot of money. That’s precisely why vehicle shoppers, new or used, should be aware that a variety of things may compromise a vehicle’s warranty, whether it’s brand-new, or a newer used model with remaining coverage.The warranty on the few-year-old car you’re considering for purchase could be voided or compromised, without you (or the seller) even knowing it. If that’s the case, you could be in for a nasty and expensive surprise, should you need a warranty-related repair down the line.

A car with a mileage number below 20,000 for example, normally still has its original tires. Even experts need to examine the car closely before being able to detect whether the car ’ s odometer has been tampered with . Digital odometers may nowadays even pose a greater risk than before.

Many car importers and local dealerships including individual sellers tamper with odometer readings when they want to make more money selling a For example, if a car is 5 years old but has far fewer than 60,000 miles, the odometer may have been tampered with . Look closely at the numbers on the

Keep in mind, your connection to your warranty pretty much starts and ends with your retailer. If they see a plug-in chip (or evidence of it) in your car’s system, they may just close the hood and prepare a retail estimate, leaving you with a long distance battle with the automaker’s head office to get some resolution.

For many performance chip fans, this doesn’t present too many concerns because they either wait until the factory warranty expires, or trust the manufacturer based on past experiences.

But while factory warranties expire, emissions regulations don’t. Many performance chips come with a warning that they are not emissions compliant and are only designed for off-road use. It’s a case of not having your cake and eating it, too – in many cases, you can’t have all the performance you can wring out of a stock engine without exceeding emission specs.

You might feel safe knowing that environment department officers seldom travel the highways looking for heavy emitters, but the long arm of the law does have a way of catching up and their fines can be substantial.

Curbsiders a Scourge of Private Vehicle Sales .
In 2017, following an investigation by the Ontario Motor Vehicle Industry Council (OMVIC), an Ottawa man was convicted of illegally selling motor vehicles. In this case, the man sold vehicles that had been written off by insurance companies to unsuspecting buyers. According to OMVIC, many of these vehicles’ airbags had been deployed and the seller did not replace them, nor did he inform the buyers that their airbag needed replacing. The man was charged with “curbsiding” for operating as a dealer without registration. He pleaded guilty to 36 counts of curbsiding. He was fined $40,000 and sentenced to two years of probation.
