TLDR;
The video discusses surprisingly unreliable cars from brands typically known for their reliability, such as Honda, Ford, and Toyota. It highlights specific models and engines to avoid due to potential major issues.
- Honda's 1.0L turbocharged 3-cylinder engine (Civic 2017 onwards) has a problematic wet belt design.
- Ford Cougar (2012-2016) with the early PowerShift automatic gearbox is prone to plastic retainer clip failures.
- Honda's 1.5L engine (CR-Vs and Civics) may suffer from fuel dilution issues.
- Toyota Rav4 (2012) diesel models can have oil pump and head gasket problems.
Honda 1.0L Turbocharged Engine [0:24]
The Honda 1.0L turbocharged 3-cylinder engine, found in Civics from 2017 onwards, uses a wet belt design, similar to Peugeot's PureTech and Ford's EcoBoost engines. This is concerning because the rubber timing belt, submerged in hot oil, can break apart, causing rubber particles to clog the engine. These particles can cause the turbo to fail. Replacing the belt and turbo is a significant job, and the issue may reoccur. It is advised to avoid this engine due to these potential problems.
Ford Cougar and Carly Diagnostic Tool [1:54]
Second-generation Ford Cougars made between 2012 and the 2016 facelift had a problematic PowerShift automatic gearbox. The plastic retainer clips inside the gearbox would fatigue and break, causing the car to lose drive. Ford redesigned the gearbox in the 2016 facelift, so it's recommended to choose a post-2016 model if you want an automatic Cougar. The speaker recommends using a Carly diagnostic tool to check for stored codes when buying a used car. Carly plugs into the OBD port and allows manufacturer-level diagnostic scans. The speaker demonstrates how Carly helped diagnose and resolve a boot issue on a Volkswagen Golf R by identifying a short circuit and a blown fuse. Carly can also unlock hidden features in cars like Volkswagen, Audi, and BMW, such as audible confirmation when unlocking and folding mirrors.
Honda 1.5L Engine Fuel Dilution [6:12]
The newer Honda 1.5L engine, found in CR-Vs and Civics, may have fuel dilution issues, where fuel finds its way into the engine oil. This issue has led to class-action lawsuits in the USA and similar concerns in China. While Honda claims there are no issues in the UK or Europe, some owners have reported rising oil levels, suggesting potential problems. Cold temperatures and short journeys are thought to exacerbate the issue. Caution is advised regarding these 1.5L engines until the extent of the problem is determined.
Toyota Rav4 Diesel Engine Issues [8:28]
The 2012 Mark III Toyota Rav4 diesel models can have issues with the oil pump, which can fail and damage the engine. They can also suffer from head gasket problems. It's recommended to stick to petrol-powered Toyotas from this era, as the diesels were not as reliable. This also applies to other Toyota diesel models like the Yaris and Avenis.
