2 It is necessary to pay attention to the behavior of the car when driving straight, on turns, during acceleration and during braking. Since most serious violations and malfunctions (which cannot be determined when the vehicle is stationary or when starting to move), manifest themselves only during movement. The consequence of malfunctions in the transmission may be jerks when the car is moving, and malfunctions in the settings or malfunctions of the chassis manifest themselves in the form of knocks and deterioration in the controllability of the car.
Car jerks while driving
1 Malfunctions in the fuel system (see chapter "Power supply system")
2 Malfunction of the ignition system (see chapter "Engine electrical equipment".)
3 Air leak in the engine intake system. In this case, when jerks occur, there is a sharp drop in engine power, no traction (see chapter "Intake and exhaust system").
4 Malfunction of the electronic transmission control system (cars with automatic transmission). You need to contact a service station to diagnose the system.
5 Malfunction of the electronic engine control system. It is necessary to contact a service station for system diagnostics.
Car jerks when braking
1 In this case, the cause may be warping of the brake disc. Therefore, it is necessary to contact the service station for repairs as soon as possible.
Note:
- In most cases, the service station will offer two options for troubleshooting, namely:
- Turning and subsequent grinding of brake discs/brake drums to repair size.
- Complete replacement of the brake disc.
- The first solution to the problem is less expensive, but there is one significant drawback - the brake pads and the brake disc must be ground in, and this will take a certain period of time, during which slight jerks will be felt when braking.
- The second option eliminates the disadvantage of the first, but it is more expensive.

2 Poor tightening of wheel nut bolts.
3 Getting mud or ice on the vehicle's braking mechanisms. In case of freezing, it is necessary to press the brake pedal several times while driving at a low speed to warm up the braking mechanisms.
