Nov 7, 2023Transmission & drivetrainEngine

While driving vehicle two "Oil Lights" on dash came on and car instantly began making a noise. Pulled over and had it towed to a service shop, they are telling me the "Oil Pump Drive Belt" broke and now the entire engine needs replaced. Upon researching this issue I come to find that this is a VERY COMMON issue that Ford is aware of but refusing to fix. This needs addressed!

Nov 2, 2023Fuel system

The purge valve problem persists well into this model year. The car is hiccuping and stalling at lights and has difficulty starting after fueling. I find it appalling that reprogramming the "check engine" light to acknowledge the defect, rather than actually repairing the defect was considered an adequate solution. My car has 59,000 miles and is just out of warranty. I think had this purge valve problem (rather than just the engine light symptom) been properly addressed by the NHTSA and Ford, my family would be safer in this car. I will never buy a Ford again.

Car failed to engage transmission at low to moderate speeds particularly when accelerating. RPMs revved with no acceleration and then engaged suddenly causing the car to lurch forward and jerked while accelerating. The check engine light appeared. The car was brought to an independent service station. Repairs were made to the computer system and motors but the problem is still not resolved. Mechanic recommends full transmission replacement at this point. Called Ford Dealer who said this is a known issue with dual transmission system. Called Ford Motor Co to make them aware of the issue and no assistance was provided (they stated that my consumer score did not qualify me for assistance but would not disclose what was impacting my score).

The purge valve has been an ongoing continuous problem since we bought the vehicle. I have fixed it multiple times. It’s caused the vehicle to stall after putting gas in the tank, and just recently stalled while driving, causing me to hit a curb leading to the passenger front tire popping, the rim being dented, the tire rod bent, alignment out of wack, and the valance ripped off. It also caused a dashboard light to pop up saying Hill Start is Not Available. I was in the car thankfully alone and not with my children. The windshield wipers are a fairly newer issue, they come on whenever they want with the switch being touch. But won’t come on when I try to do it myself. I had my mom take a photo of the steering wheel/road while I was driving to show the severity of the alignment needed, it’s causing extra wear and tear EXTREMELY fast on tires. Rainy season has begun and this is absolutely unsafe and not my responsibility.

When you accelerate the car hesitates and shakes, the rpm needle goes way up even though you are creeping along. It seems like it is a recall issue on earlier model Ford Focus's. The recall should be extended to all model years. There is no reason I should have to spend money to repair a transmission issue on a 5 year old car. It is sitting out on the street not being driven while I make payments, not a happy camper. The check engine light comes on also, if someone was following too close and it starts sputtering it could cause an accident, a auto parts store checked it out- Most likely solution-"Replace Dual Clutch Transmission Clutch Assembly"

My oil light is flickering. I have taken it to 3 different mechanics, one of which is a Ford dealership. Oil is getting on the timing belt, causing it to fray. Oil is being prevented from getting to the engine efficiently. They all state that the problem is a design issue, and that having it repaired will fix it for awhile, but the problem will continue later.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Ford Focus RS verdict →
