Engine, power train, malfunction changing my speed control. No warning lights, first ticking noise from engine then knocking loud noise from engine. Noticed ticking about 4 days ago at first, today on freeway going 60-70 mph just changed to loud knocking, immediately engine warning starts to flash on dash board then speed just drops from 60-70 mph to 35 mph almost got hit by trucker and another car . Under 90 day warranty still from dealership (27 days since purchased) no license plate yet but insured and registered. Read many complaints of the same problems from numerous of people having the exact same problem. Very dangerous when vehicle stops accelerating on a steep pass on hwy with heavy traffic, this was almost an accident report to dispatch but luckily I reacted fast enough to swerve to the side before hitting the vehicle behind me and missing 18 wheeler trying to get to the right shoulder because theirs no space on left just concrete dividers! To close for comfort I can imagine what really can happen to someone that can't react as quickly as I did. Feeling like a victim their is no way they were not aware of this problem that has happened to many others when it is coming from a Chrysler dealership after reading so many complaints and reviews. I wish I would of known before hand ️ I would of not even bothered but now this is what I'm dealing with instead of feeling safe and comfortable being in a reliable, gas efficient vehicle that I just purchased for $30,000 and my jeep as a down payment not happy with dealership nor product. Who do I look to, when insurance or dealership can't protect me from situations like this it's not fair to someone that's struggling day by day paycheck to paycheck and this happens and now on waiting list until December so dealership is able to take a look at it. This should be most definitely brought to attention!!!

CAR SHUT OFF WHILE ON THE HIGHWAY RANDOMLY STARTED SHAKING. ALL LIGHTS TURNED ON CHECK ENGINE,MOTOR OIL LIGHT BATTERY LIGHT. CAR SHUT OFF TO THE POINT WHERE I COULDN'T ACCELERATE. SO IMAGINE BEING ON THE HIGHWAY AND YOUR CAR SHUTS OFF RANDOMLY WHILE YOUR IN MOTION AND CANT ACCELERATE TO MERGE TO THE EMERGENCY LANE. THIS HAPPENED 4 MORE TIMES ON MY WAY TO THE DEALERSHIP LESS THEN 800 MILES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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 Hyundai Elantra Gt verdict →
